    Earth now halfway to UN global warming limit

    29 July 2015 (New Scientist)

    “…All but one of the main trackers of global surface temperature are now passing more than 1 °C of warming relative to the second half of the 19th century…[and we] could also be seeing the end of the much-discussed slowdown in surface warming since 1998, meaning this is just the start of a period of rapid warming…Last year was the hottest since records began, but only just. With an El Niño now under way – meaning warm surface waters in the Pacific are releasing heat into the atmosphere – and predicted to intensify, it looks as if the global average surface temperature could jump by around 0.1 °C in just one year…The UN negotiations on climate change aim to limit warming to 2 °C above pre-industrial temperatures…[I]f climate talks do not lead to drastic action, we could pass the 2 °C mark around the middle of the century…[T]emperatures might briefly drop next year after the current El Niño ends…[but] with global emissions of greenhouse gases rising ever faster, [the planet may continue to warm at a rate more like those from 1984 to 1998, when it warmed at 0.26 °C per decade]…” click here for more

    Atoms for electricity: Inside Exelon's push to save its Illinois nuclear fleet; Exelon says its nukes need backing, others say nukes shouldn’t get another bailout

    Herman K. Trabish, February 26, 2015 (Utility Dive)

    Exelon’s new plan to support aging nuclear plants and cut carbon emissions is putting a big decision in front of Illinois lawmakers.

    Will legislators make ratepayers rescue Exelon’s uncompetitive nukes to sustain reliability and an influential economic sector? Or will they turn to renewables and energy efficiency to fill the gap when the plants retire?

    “There are likely to be tremendous cutbacks of basic social services and the legislature is likely to have to raise taxes or fees to make the budget balance,” said Environmental Law and Policy Center Executive Director Howard Learner. “Will legislators at the same time force consumers, through a non-bypassable charge, to pay hundreds of millions of dollars each year for the next six years to bail out Exelon nuclear plants?”

    But many who make their livelihoods in and around the nuclear plants see things a bit differently.

    “Part of the upcoming debate in Springfield should focus on what these plants mean to their host communities,” read a letter signed by Mayors from six nuclear plant neighbor cities. "Illinois nuclear facilities provide thousands of good jobs; the kind of jobs you can support a family on ..."

    What Illinois stands to gain and lose

    In Potential Nuclear Plant Closings in Illinois, a report to the legislature, four state agencies recommend a Low Carbon Fuel Standard (LCFS) as one of five market-based solutions to the challenges facing Exelon. Other possible solutions assessed by the agencies are (1) pure market economics, (2) a carbon tax, (3) a cap and trade program, or (4) a sustainable power standard.

    In the report, the Illinois Commerce Commission concludes negative economic impacts from the closures would include:

    2,500 direct job losses at the nuclear plants

    4,431 indirect job losses at local businesses

    $1.8 billion in annual lost economic activity

    a 10% to 16% increase in wholesale power prices which would cause further economic impacts, including 896 job losses and $45 million in lost economic activity

    Regional grid operators PJM and MISO calculate, according to Exelon, that early nuclear plant closures would drive Illinois electricity prices up 10%, costing Commonwealth Edison customers $437 million and Ameren customers $810 million to $1.2 billion in the first year.

    Investments in energy efficiency and renewables would, however, create 9,600 new jobs by 2019 and $120 million in annual energy cost savings from lower electricity prices, the Commerce Commission concluded.

    The Better Energy Solutions for Tomorrow (BEST) Coalition and the Chicago Mayor Rahm Emanuel-led Clean Jobs Coalition argue efficiency and renewables offer a more sustainable alternative to the nuclear plants.

    Exelon’s LCFS is a cornerstone of both Senate Bill 1585 and House Bill 3293, legislation that Exelon argues would “help reduce carbon emissions, increase renewable energy, and maintain affordable, reliable electricity for consumers and businesses” as well as “ensure continued operations of the state’s nuclear power plants.”

    “Illinois needs an all-of-the-above energy strategy that will help reduce harmful air emissions, grow renewable energy and maintain our state’s existing nuclear plants,” said Senator Mattie Hunter (D-Chicago).

    “This comprehensive legislation balances the need to preserve our nuclear plants while at the same time promoting other low-carbon energy resources such as wind, solar, hydro and clean coal,” said Senator Sue Rezin (R-Morris).

    The cost of nuclear power

    Flat or declining Illinois electricity demand has resulted in an electricity oversupply thanks to Exelon’s 11-plant nuclear fleet, Dynegy and NRG coal fleets, existing, retrofitted, and new natural gas facilities, and a growing wind portfolio, according to Learner. With all these merchant generation sources fighting for a share of the competitive power markets, prices are falling.

    “That means the less economically efficient plants are getting squeezed out,” Learner said. That’s good for consumers and the Illinois economy. But it is bad for Exelon because, he added, “the less efficient either have to cut prices or shut down.”

    While Exelon’s LaSalle, Braidwood, and Dresden units remain competitive, the Clinton and Quad Cities units are not, and the Byron units are marginal, Learner said.

    “As an NRC Commissioner, I licensed about twenty nuclear plants,” said Vermont Law School Adjunct Professor Peter Bradford, who also served as Chair of the Maine and New York utilities commissions. “But now nuclear just doesn’t make the cut economically.”

    Contrary to Exelon claims, it is not low natural gas prices or negative power market prices caused by wind’s production tax credit that are the cause of its plants' financial problems, Bradford said.

    “Ten years ago, the operations cost was between $0.01 per kWh and $0.02 per kWh but now, largely because of substantial capital investment needs, the operating cost is between $0.04 per kWh and $0.05 per kWh,” Bradford explained. “If plants were still able to operate in the $0.01 per kWh to $0.02 per kWh range, they would be fine.”

    Not one, but two previous bailouts

    Exelon’s LCFS will require Illinois investor owned utilities to purchase low-carbon energy credits for 70% of their power. Eligible sources would be solar, wind, hydro, nuclear, tidal, wave, and clean coal. The standard sunsets at the end of 2021, or when an EPA Clean Power Plan program supersedes it. It cannot increase electricity customer rates more than 2.015% above 2009 levels, or about $2 per month. Excess revenues would be rebated.

    “Exelon is asking the legislature to change the rules of the competitive market in a way that would bail out its economically uncompetitive nuclear plants,” Learner said. “It wants to essentially re-regulate and require utilities to purchase 70% of their power from nuclear plants owned by Exelon. And force consumers to pay for it, even if the price is above the current market price.”

    “Those reactors were already bailed out once,” Bradford added. “When electric restructuring led to competitive power markets, the nuclear plant owners insisted on stranded cost recovery.”

    They were bailed out again last spring by PJM, Learner pointed out. By withholding part of its fleet from the May 2014 PJM capacity market auction, Learner explained, prices cleared at $120 per MW-day, doubling the RTO-wide clearing price of $59 per MW-day for planning year 2016/17. That produced, he reported from a UBS Bank analysis, almost $150 million more in capacity revenue for planning year 2017/18.

    Exelon “couldn't have played its hand any better in the capacity auction,” one account of the UBS analysis reported.

    Even if Illinois legislators go along with the Exelon-backed bills, “there is no reason to think this will be the last time Exelon has to come around,” Bradford said. “Even if gas prices don’t go lower, developments in storage, solar, and efficiency will put downward pressure on power prices and operational costs will continue to put upward pressure on nuclear plant costs.”

    Kicker: The PJM capacity market auction

    Though many think Exelon will get its way, Learner is unconvinced.

    "I’m not saying it won’t happen, but the legislative session runs to at least the end of May,” he said. “PJM’s May capacity market auction could well provide considerable revenue to Exelon. Some in the legislature will ask how many gifts from the public wallet and business’s bottom line Exelon is going to get for the same nuclear plants.”

    Drivers of the US CO2 emissions 1997–2013

    Feng, Davis, t. al., July 21, 2015 (Nature Communications)


    Fossil fuel CO2 emissions in the United States decreased by B11% between 2007 and 2013, from 6,023 to 5,377 Mt. This decline has been widely attributed to a shift from the use of coal to natural gas in US electricity production. However, the factors driving the decline have not been quantitatively evaluated; the role of natural gas in the decline therefore remains speculative. Here we analyse the factors affecting US emissions from 1997 to 2013. Before 2007, rising emissions were primarily driven by economic growth. After 2007, decreasing emissions were largely a result of economic recession with changes in fuel mix (for example, substitution of natural gas for coal) playing a comparatively minor role. Energy–climate policies may, therefore, be necessary to lock-in the recent emissions reductions and drive further decarbonization of the energy system as the US economy recovers and grows.

    The CO2 emissions from the burning of fossil fuels are the primary cause of anthropogenic climate change1, and the United States emits more CO2 each year than any other country except China. In the decade before 2007, US CO2 emissions grew by an average 0.7% per year. However, beginning in 2007, US emissions decreased, reaching a minimum of 5,284 Mt CO2 in 2012—12% lower than 2007 levels and 5% lower than 1997 levels2. This recent decline is good news and is consistent with the Obama administration’s stated goal of reducing CO2 emissions by 17% in 2020 and 83% in 2050 relative to 2005 levels3. Assuming no change in emissions outside the power sector, the new rules proposed by the US Environmental Protection Agency in June 2014 to limit CO2 emissions from power plants will require US emissions to decrease to 4,200 Mt CO2 in 2030—a further 20% reduction from 2013 levels4.

    Coinciding with the post-2007 decline in emissions, innovations in hydraulic fracturing technology have dramatically increased domestic supplies of gas5,6. Commentators in the scientific community and media have linked the two trends, celebrating the climate benefits of the gas boom7–9. Recently, the Third National Climate Assessment of the United States Global Change Research Program also adopted this conclusion, stating that the decrease in US CO2 emissions was ‘ylargely due to a shift from coal to less CO2-intensive natural gas for electricity production’10. Yet, despite potentially significant implications for US climate and energy policy, there has been no quantitative analysis of whether the gas boom and changes in the fuel mix of the power sector are indeed driving the decrease in US CO2 emissions.

    Here, we use input–output structural decomposition analysis (SDA) to assess sources of change in US CO2 emissions over a decade of mostly increasing emissions, 1997–2007, and then over the period of mostly decreasing emissions, 2007–2013. Our analysis quantifies the contribution of six different factors to changes in US emissions. These factors are: population growth; changes in consumption volume caused exclusively by changes in per capita consumption of goods and services; shifts in consumption patterns or the types of goods and services being consumed; adjustments in production structure or the mix of inputs (for example, labour, domestic and imported materials) required to produce US goods and services; changes in fuel mix as reflected by the CO2 emitted per unit of energy used; and changes in energy intensity or the energy used per inflation-adjusted unit of economic output. The SDA in this research is based on the additive decomposition of the changes in emission determined by six multiplicative factors acting as accelerators or retardants of the emission dynamics. Each term in the decomposition is a product of the change in one explicative factor and the level values of the other five factors, and thus represents the contribution of one explicative factor to the total change in emission. For example, in the term where population is the explicative factor, the values of consumption volume, production structure, consumption patterns, energy intensity and fuel mix are held unchanged and only population varies. In this way, the SDA method allows us to quantify the contribution of each of the assessed factors to the trend in emissions. Details of our methodology and data sources are in the Methods section (including Supplementary Methods). We find that before 2007, rising emissions were driven by economic growth: 71% of the increase between 1997 and 2007 was due to increases in US consumption of goods and services, with the remainder of the increase due to population growth. Concurrent with the global economic recession, 83% of the decrease during 2007–2009 was due to decreased consumption and changes in the production structure of the US economy, with just 17% related to changes in the fuel mix. During the economic recovery, 2009–2013, the decrease in US emissions has been small (o1%), with nearly equal contributions from changes in the fuel mix, decreases in energy use per unit of GDP, changes in US production structure, and changes in consumption patterns. We conclude that substitution of gas for coal has had a relatively minor role in the emissions reduction of US CO2 emissions since 2007.


    Growing emissions from 1997 to 2007. Between 1997 and 2007, US emissions increased by 7.3% (Fig. 1, black curve). Our analysis shows that the main factor behind this increase was an increase in consumption volume caused by growth in per capita consumption of goods and services in the United States. Indeed, increases in such consumption volume correspond to a contribution of a 21.8% increase in emissions over this decade (Fig. 1, red curve). The next most important factor influencing CO2 emissions over the same period was population growth. Immigration and natural growth have resulted in steady population growth at a rate of B1% per year since 1997. These population gains contributed to an 8.9% increase in emissions between 1997 and 2007 (Fig. 1, yellow curve).

    However, other factors slowed the growth of emissions between 1997 and 2007: decreases in the energy intensity of GDP; changes in the consumption patterns of US consumers; shifts in production structure; and decreases in the use of coal as an energy source. For instance, over this period, the energy used per dollar of economic output decreased by 17% (Fig. 2a, black curve), the share of consumer spending on manufactured goods decreased by B4% (Fig. 2b), the share of imported inputs to the US industry sectors increased (for example, imports to petroleum and coal products sector increased by 6.7%, and imports to the chemical products, primary metals and textile sectors increased by 2.7%, 2.5% and 2.1%, respectively)11, and the share of US electricity generated from coal decreased by B5% while the share generated from natural gas increased by 8% (Fig. 2c). All of these trends exerted a downward influence on emissions. Between 1997 and 2007, changes in energy intensity, consumption patterns, production structure and fuel mix contributed to retarding emissions of 7.4, 6.9, 4.9 and 3.6%, respectively (Fig. 1, purple, green, blue and orange curves, respectively).

    Declining emissions from 2007 to 2013. US CO2 emissions stopped growing in 2007, and decreased by B11% between 2007 and 2013 (Fig. 1, black curve). Looking at this time period in aggregate, the only factor which acted to increase emissions over the period was continued and steady population growth ( þ 3.7%) (Fig. 1, yellow curve). However, the upward influence of population growth was overwhelmed by the downward influence of changes in production structure ( 6.1%), fuel mix ( 4.4%), consumption volumes triggered by per capita consumption ( 3.9%), energy intensity of GDP ( 0.5%) and changing consumption patterns ( 0.4%; Fig. 1, blue, orange, red, purple and green curves, respectively).

    Although all of the analysed factors except population contributed to the decrease in emissions during 2007–2013, different factors dominated over shorter periods. Figure 3 subdivides 2007-2013 into 2-year periods, showing that emissions fell by 9.9% from 2007 to 2009, increased by 1.3% between 2009 to 2011 and decreased again by 2.1% between 2011 and 2013.

    More than half (53%) of the initial and most substantial decrease in emissions, between 2007 and 2009, was due to a sharp drop in the volume of consumed goods as a result of reduction in per capita consumption during the global economic recession (Fig. 3, red bar). In particular, Fig. 4 shows that sharp decreases in the volume of capital expenditures and exported goods between 2007 and 2009 drove down associated emissions by 25% and 18%, respectively. Changes in the production structure of the US economy (that is, the volume and type of intermediate goods demanded) and the fuel mix of the energy sector contributed 30% and 17% of the initial (2007–2009) decrease in emissions, respectively, while increases in the energy intensity of the US economy and changing consumption patterns exerted modest upward influences on emissions during the same period.

    As the US economy had slowly recovered from the global economic recession, between 2009 and 2013, the average annual change in US emissions was small: a 0.2% decrease. Economic recovery is reflected by the upward influence of the volume of goods consumed on emissions during both 2009–2011 and 2011–2013. Between 2009 and 2011, rising consumption volume, population growth, and increasing energy intensity urged emissions up by a combined 4.0% (2.2%, 1.5% and 0.3%, respectively), which was only partly offset by the changes in consumption patterns ( 1.1%), production structure ( 1.0%) and fuel mix ( 0.6%), resulting in an actual increase in emissions of 1.3% (Fig. 3). However, between 2011 and 2013, the upward influence of consumption volume and population on emissions was less ( þ 1.2% and þ 1.2%, respectively) and the energy intensity of the economy decreased ( 2.1%). When combined with changes in the fuel mix of the energy sector ( 1.2%) and shifting consumption patterns ( 0.2%), the net effect was a 2.1% decrease in emissions during 2011–2013 (Fig. 3).

    Increases in the supply of natural gas affect two of the factors in our analysis: the fuel mix of the energy sector and, to a lesser extent, the energy intensity of the US economy. By decreasing gas prices, abundant gas encourages a shift in the fuel mix from more carbon-intensive coal to gas. In turn, a shift to gas may contribute to decreased energy intensity because gas-fired power plants are on average 20% more efficient at converting fuel energy to electricity than coal plants12.

    The boom of natural gas from breakthroughs in hydraulic fracturing of shale deposits had only just begun to affect US gas supplies in 2009 (ref. 5). Thus, the decrease in emissions from changes in the fuel mix of the energy sector prior 2009 reflects an independent and longer-term trend of the declining use of coal in the US energy sector (see, for example, Fig. 2c). However, as seen in Fig. 3, changes in the US fuel mix from 2007 to 2009 alone would not have caused a decrease in US emissions.

    Although the decreases in emissions since 2009 have been relatively small, the influence of shale gas is visible. For example, about half of the 2.1% decrease in emissions during 2011–2013 is related to changes in the fuel mix of the energy sector ( 1.2%, orange bar in Fig. 3). Yet the decrease in the energy intensity of the US economy was nearly twice as strong an influence on emissions over the same period (purple bar in Fig. 3).

    Although a drop in the energy intensity (exajoule per dollar output) of the energy sector in 2013 accounts for roughly a third of the observed decrease in US energy intensity in 2011–2013, the remaining two-thirds relate to changes in energy used by the transport and service sectors (Fig. 2a). Three unrelated trends underlie the decreasing energy intensity of these sectors. First, high gasoline prices during 2011–2013 (the average price of gasoline had remained above $3.40 per gallon during this period, in contrast to the average price of $2.50 per gallon in 2005) have contributed to both a reduction in per capita miles driven (Supplementary Fig. 1a) and an increase in average fuel efficiency of vehicles (Supplementary Fig. 1b), and thus a 33% decrease in US gasoline consumption during 2011–2013. Second, a mild winter in 2012 meant less energy was used for heating and thus reduced energy intensity of the service sector (households also used less energy for home heating, which accounts for part of the drop in consumption volume)13 (Supplementary Fig. 2). Last, there is evidence that manufacturing in the United States became more energy efficient: energy use by manufacturing was nearly constant 2011–2013 despite average annual growth in GDP of 2.3% per year over the same period.

    Shifts in the production structure of the US economy between 2007 and 2013 have consistently exerted a downward influence on US emissions, as the volume and type of intermediate goods used by various industry sectors has evolved and become more efficient (blue bars in Fig. 3). Yet this structural shift also reflects the progressive offshoring of emissions-intensive industries to China and other developing countries over the analysed period14. For instance, between 2009 and 2011, when changes in domestic production structure exerted a downward influence on US CO2 emissions ( 1%, blue bar in Fig. 3), we calculated that the net import of emissions embodied in US trade increased by 32% (Supplementary Fig. 3). Trade data for the 2011–2013 period is not yet available.

    Between 2009 and 2013, the share of US consumption of manufactured goods increased relative to services (Fig. 2b), but the net effect of changes in consumption patterns was to decrease emissions (by 1.1% between 2009 and 2011 and by 0.2% between 2011 and 2013; green bars in Fig. 3). This result reveals that changes in the types of goods being consumed over time can have a significant impact on emissions15,16, and that it is not as simple as the balance of manufactured goods and services…

    Decomposing Final Demand. Because changes in the volume of goods and services consumed were the single most important influence on US emissions between 1997 and 2013, we also analysed four separate components of final demand to assess the trends in emissions related to each category as well as the important influences on emissions in each case. Figure 4 shows the emissions associated with different final demand (consumption) components: household consumption (Fig. 4a), governmental expenditure (Fig. 4b), capital formation (Fig. 4c) and exports (Fig. 4d).

    Between 2007 and 2013, emissions associated with household consumption decreased by 11.0%, which was almost entirely driven by changes in fuel mix and production structure, especially between 2009 and 2013, since consumption volume was constant (Fig. 4a). Emissions associated with government expenditures in the same time period decreased by 4.8%, and it was largely driven by changes in energy intensity and production structure (Fig. 4b). In contrast, emissions related to capital formation decreased by 24.4% between 2007 and 2013, primarily due to a huge decline in the volume of capital investment (Fig. 4c, red curve). However, changes in emissions related to exports between 2007 and 2013 were almost entirely the result of changes in the volume of exports, with the other factors cancelling each other out (Fig. 4d).

    Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 ◦C global warming is highly dangerous

    Hansen, et. al., July 23, 2015 (Atmospheric Chemistry and Physics)


    There is evidence of ice melt, sea level rise to +5–9 m, and extreme storms in the prior interglacial period that was less than 1 ◦C warmer than today. Human-made climate forcing is stronger and more rapid than paleo forcings, but much can be learned by 5 combining insights from paleoclimate, climate modeling, and on-going observations. We argue that ice sheets in contact with the ocean are vulnerable to non-linear disintegration in response to ocean warming, and we posit that ice sheet mass loss can be approximated by a doubling time up to sea level rise of at least several meters. Doubling times of 10, 20 or 40 years yield sea level rise of several meters in 50, 100 or 10 200 years. Paleoclimate data reveal that subsurface ocean warming causes ice shelf melt and ice sheet discharge. Our climate model exposes amplifying feedbacks in the Southern Ocean that slow Antarctic bottom water formation and increase ocean temperature near ice shelf grounding lines, while cooling the surface ocean and increasing sea ice cover and water column stability. Ocean surface cooling, in the North Atlantic 15 as well as the Southern Ocean, increases tropospheric horizontal temperature gradients, eddy kinetic energy and baroclinicity, which drive more powerful storms. We focus attention on the Southern Ocean’s role in affecting atmospheric CO2 amount, which in turn is a tight control knob on global climate. The millennial (500–2000 year) time scale of deep ocean ventilation affects the time scale for natural CO2 change, thus the time 20 scale for paleo global climate, ice sheet and sea level changes. This millennial carbon cycle time scale should not be misinterpreted as the ice sheet time scale for response to a rapid human-made climate forcing. Recent ice sheet melt rates have a doubling time near the lower end of the 10–40 year range. We conclude that 2 ◦C global warming above the preindustrial level, which would spur more ice shelf melt, is highly danger- 25 ous. Earth’s energy imbalance, which must be eliminated to stabilize climate, provides a crucial metric.


    Humanity is rapidly extracting and burning fossil fuels without full understanding of the consequences. Current assessments place emphasis on practical effects such as increasing extremes of heat waves, droughts, heavy rainfall, floods, and encroaching 5 seas (IPCC, 2014; USNCA, 2014). These assessments and our recent study (Hansen et al., 2013a) conclude that there is an urgency to slow carbon dioxide (CO2 ) emissions, because the longevity of the carbon in the climate system (Archer, 2005) and persistence of the induced warming (Solomon et al., 2010) may lock in unavoidable highly undesirable consequences.

    Despite these warnings, global CO2 emissions continue to increase as fossil fuels remain the primary energy source. The argument is made that it is economically and morally responsible to continue fossil fuel use for the sake of raising living standards, with expectation that humanity can adapt to climate change and find ways to minimize effects via advanced technologies.

    We suggest that this viewpoint fails to appreciate the nature of the threat posed by ice sheet instability and sea level rise. If the ocean continues to accumulate heat and increase melting of marine-terminating ice shelves of Antarctica and Greenland, a point will be reached at which it is impossible to avoid large scale ice sheet disintegration with sea level rise of at least several meters. The economic and social cost of losing 20 functionality of all coastal cities is practically incalculable. We suggest that a strategic approach relying on adaptation to such consequences is unacceptable to most of humanity, so it is important to understand this threat as soon as possible.

    We examine events late in the last interglacial period warmer than today, called Marine Isotope Stage (MIS) 5e in studies of ocean sediment cores, Eemian in European 25 climate studies, and sometimes Sangamonian in American literature (see Sect. 5 for timescale diagram of Marine Isotope Stages). Accurately known changes of Earth’s astronomical configuration altered the seasonal and geographical distribution of incoming radiation during the Eemian. Resulting global warming was due to feedbacks that amplified the orbital forcing. While the Eemian is not an analog of future warming, it is useful for investigating climate feedbacks, the response of polar ice sheets to polar warming, and the interplay between ocean circulation and ice sheet melt.

    Our study relies on a large body of research by the scientific community. After intro- 5 ducing evidence concerning late Eemian climate change, we analyze relevant climate processes in three stages. First we carry our IPCC-like climate simulations, but with growing freshwater sources in the North Atlantic and Southern Oceans. Second we use paleoclimate data to extract information on key processes identified by the modeling. Third we use modern data to show that these processes are already spurring 10 climate change today…

    Summary implications

    Humanity faces near certainty of eventual sea level rise of at least Eemian proportions, 15 5–9 m, if fossil fuel emissions continue on a business-as-usual course, e.g., IPCC scenario A1B that has CO2 ∼ 700 ppm in 2100 (Fig. S21). It is unlikely that coastal cities or low-lying areas such as Bangladesh, European lowlands, and large portions of the United States eastern coast and northeast China plains (Fig. S22) could be protected against such large sea level rise.

    Rapid large sea level rise may begin sooner than generally assumed. Amplifying feedbacks, including slowdown of SMOC and cooling of the near-Antarctic ocean surface with increasing sea ice, may spur nonlinear growth of Antarctic ice sheet mass loss. Deep submarine valleys in West Antarctica and the Wilkes Basin of East Antarctica, each with access to ice amounting to several meters of sea level, provide gateways 25 to the ocean. If the Southern Ocean forcing (subsurface warming) of the Antarctic ice sheets continues to grow, it likely will become impossible to avoid sea level rise of several meters, with the largest uncertainty being how rapidly it will occur.

    The Greenland ice sheet does not have as much ice subject to rapid nonlinear disintegration, so the speed at which it adds to 21st century sea level rise may be limited. However, even a slower Greenland ice sheet response is expected to be faster than carbon cycle or ocean thermal recovery times. Therefore, if climate forcing continues 5 to grow rapidly, amplifying feedbacks will assure large eventual mass loss. Also with present growth of freshwater injection from Greenland, in combination with increasing North Atlantic precipitation, we already may be on the verge of substantial North Atlantic climate disruption.

    Storms conjoin with sea level rise to cause the most devastating coastal damage. 10 End-Eemian and projected 21st century conditions are similar in having warm tropics and increased freshwater injection. Our simulations imply increasing storm strengths for such situations, as a stronger temperature gradient caused by ice melt increases baroclinicity and provides energy for more severe weather events. A strengthened Bermuda High in the warm season increases prevailing northeasterlies that can help 15 account for stronger end-Eemian storms. Weakened cold season sea level pressure south of Greenland favors occurrence of atmospheric blocking that can increase wintertime Arctic cold air intrusions into northern midlatitudes.

    Effects of freshwater injection and resulting ocean stratification are occurring sooner in the real world than in our model. We suggest that this is an effect of excessive small 20 scale mixing in our model that limits stratification, a problem that may exist in other models (Hansen et al., 2011). We encourage similar simulations with other models, with special attention to the model’s ability to maintain realistic stratification and perturbations. This issue may be addressed in our model with increased vertical resolution, more accurate finite differencing method in ocean dynamics that reduces noise, and 25 use of a smaller background diffusivity.

    There are many other practical impacts of continued high fossil fuel emissions via climate change and ocean acidification, including irreplaceable loss of many species, as reviewed elsewhere (IPCC, 2013, 2014; Hansen et al., 2013a). However, sea level rise sets the lowest limit on allowable human-made climate forcing and CO2 , because of the extreme sensitivity of sea level to ocean warming and the devastating economic and humanitarian impacts of a multi-meter sea level rise. Ice sheet response time is shorter than the time for natural geologic processes to remove CO2 from the climate system, so there is no morally defensible excuse to delay phase-out of fossil fuel emissions as 5 rapidly as possible.

    We conclude that the 2 ◦C global warming “guardrail”, affirmed in the Copenhagen Accord (2009), does not provide safety, as such warming would likely yield sea level rise of several meters along with numerous other severely disruptive consequences for human society and ecosystems. The Eemian, less than 2 ◦C warmer than pre-industrial 10 Earth, itself provides a clear indication of the danger, even though the orbital drive for Eemian warming differed from today’s human-made climate forcing. Ongoing changes in the Southern Ocean, while global warming is less than 1 ◦C, provide a strong warning, as observed changes tend to confirm the mechanisms amplifying change. Predicted effects, such as cooling of the surface ocean around Antarctica, are occurring 15 even faster than modeled.

    Our finding of global cooling from ice melt calls into question whether global temperature is the most fundamental metric for global climate in the 21st century. The first order requirement to stabilize climate is to remove Earth’s energy imbalance, which is now about +0.6 W m−2 , more energy coming in than going out. If other forcings are unchanged, removing this imbalance requires reducing atmospheric CO2 20 from ∼ 400 to ∼ 350 ppm (Hansen et al., 2008, 2013a).

    The message that the climate science delivers to policymakers, instead of defining a safe “guardrail”, is that fossil fuel CO2 emissions must be reduced as rapidly as practical. Hansen et al. (2013a) conclude that this implies a need for a rising carbon 25 fee or tax, an approach that has the potential to be near-global, as opposed to national caps or goals for emission reductions. Although a carbon fee is the sine qua non for phasing out emissions, the urgency of slowing emissions also implies other needs including widespread technical cooperation in clean energy technologies (Hansen et al., 2013a).

    The task of achieving a reduction of atmospheric CO2 is formidable, but not impossible. Rapid transition to abundant affordable carbon-free electricity is the core requirement, as that would also permit production of net-zero-carbon liquid fuels from electricity. The rate at which CO2 emissions must be reduced is about 6 % yr−1 to reach 5 350 ppm atmospheric CO2 by about 2100, under the assumption that improved agricultural and forestry practices could sequester 100 GtC (Hansen et al., 2013a). The amount of CO2 fossil fuel emissions taken up by the ocean, soil and biosphere has continued to increase (Fig. S23), thus providing hope that it may be possible to sequester more than 100 GtC. Improved understanding of the carbon cycle and non-CO2 10 forcings are needed, but it is clear that the essential requirement is to begin to phase down fossil fuel CO2 emissions rapidly. It is also clear that continued high emissions are likely to lock-in continued global energy imbalance, ocean warming, ice sheet disintegration, and large sea level rise, which young people and future generations would not be able to avoid. Given the inertia of the climate and energy systems, and the grave 15 threat posed by continued high emissions, the matter is urgent and calls for emergency cooperation among nations.

    HP to Power Texas Data Centers With Wind Energy

    The list of corporate purchasers of wind is expanding rapidly. Last week, Hewlett-Packard announced a 12-year contract for 112 MW from a SunEdison Texas wind project. And a long term contract with Amazon Web Services allowed Iberdrola Renewables to break ground on the 208 MW Amazon Wind project in North Carolina, the Southeast’s first utility-scale wind installation. In February, Kaiser Permanente signed a 20-year contract for 153 MW of California wind and solar. In March, Dow Chemical contracted for 200 MW of Texas wind. Some 60 non-utility entities have contracted for wind, including IKEA, Facebook, Google, Mars, and Anheuser-Busch. They are buying renewables to meet corporate sustainability goals but also because, like utilities, they see the long term, fixed price contract as a hedge against fossil fuel price volatility. click here for more

    What electric reliability is actually worth and what it means for utilities; LBNL’s new numbers on the value of service reliability are revealing

    Herman K. Trabish, February 25, 2015 (Utility Dive)

    The cost of outages to utility customers is not always adequately included in utility planning, according to experts at calculating those costs.

    But Pacific Gas and Electric (PG&E) and Southern Company, two very different types of investor owned utilities, are among the most advanced atincluding the cost into their planning. That raises a very interesting question about the way utilities spend money.

    “Utilities usually plan to certain minimum requirements or only consider their own costs and benefits,” according to Nexant Utility Services Managing Consultant Josh Schellenberg, co-author of the just-released report, "Updated Value of Service Reliability Estimates for Electric Utility Customers" from Lawrence Berkeley National Laboratory (LBNL).

    “By providing a meta-analysis to understand the customer benefits associated with various types of reliability interruptions,” Schellenberg said, “this report helps address one of the barriers to utilities incorporating the customer perspective.”

    Incorporating customer interruption costs into planning, which is known as "value-based reliability planning," leads to a much better assessment of the societal costs and benefits, Schellenberg said.

    Often the utility is comparing multiple investments, he added. If it looks only at utility costs and benefits and doesn’t incorporate the customer perspective, it could make the wrong decision because “the customer may benefit greatly from one investment and not much from another investment.”

    Who gets the costs and benefits?

    Utility benefits from reliability investments include operations and maintenance savings and lower restoration of service costs. Though the utility incurs costs for reliability investments, those costs are generally recovered from ratepayers in time.

    “Power interruptions can be incredibly costly to customers, especially to commercial-industrial customers,” Schellenberg said. “Ignoring the potential benefits to customers in the cost-benefit assessment of reliability investments can undervalue them.”

    The LBNL survey provides three key metrics for planners:

    the cost for an individual interruption for a typical customer

    the cost per average kilowatt (kW)

    the cost per unserved kilowatt-hour (kWh), which is the expected amount of unserved kWhs for each interruption and is relatively high for a momentary interruption because the unserved kWhs in a 5-minute period is relatively low.

    The national average price of residential electricity for 2014 was $0.1246 per kWh, according to the U.S. Energy Information Administration. The average commercial electricity price was $0.1071 per kWh and the average industrial price was $0.0703 per kWh.

    The values derived from the survey, soon to be publicly acessible through the Department of Energy ICE Calculator, show customers value their electricity at “orders of magnitude larger than what they pay for the electricity,” Schellenberg said. "That shows interruptions can be highly costly to customers and utilities should incorporate those costs into planning.”

    The electricity not provided that a medium to large commercial and industrial (C&I) customer otherwise would have consumed, the survey shows, is valued at $21.80 per kWh. For the small C&I customer, the value for a one hour outage is $295 per kWh. For the residential customer, it is $3.30 per kWh.

    How to use the numbers

    Demonstrating the high value customers place on reliability to regulators can be a power lever in justifying utility spending, Scehllenberg acknowledged.

    “Tell me something a utility does that doesn’t affect reliability,” he said. "Tree trimming is about reliability. Demand response affects reliability. Distributed batteries and solar can affect reliability. Improving the call center could affect reliability.”

    PG&E incorporated interruption costs into many of their proposals for reliability investments on the transmission and distribution side in their last rate case, Schellenberg said. Southern Company has incorporated interruption costs into their generation planning for about 20 years.

    “There are two basic kinds of outage,” explained Regulatory Assistance Project (RAP) Senior Advisor Jim Lazar. RAP is a global, non-profit team led by former regulators that provides guidance on power sector economic, environmental, reliability and benefit allocation issues.

    Outages from a shortage of generation are “very very unusual,” Lazar said. “Transmission and distribution system failures are far more common. The average customer experiences one of those per year.”

    There is a supply curve for reliability services, Lazer went on.

    “The cheapest are things that can be delayed or done without for a few hours," he said. "At the high end of the scale is building utility scale generation, plus transmission, plus distribution upgrades for reliability that is only needed a few hours per year."

    Regulators must understand the supply curve and “figure out the best way to acquire the options at the cheap end of the curve,” Lazar said. "Utility scale generation, transmission, and distribution is a very, very expensive solution. It is an appropriate expenditure for providing thousands of hours of service per year but inappropriate for one hour every ten years.”

    The key question to ask about Southern Company’s use of the costs and benefits to customers of outages to justify expenditures for new generation is whether they are necessary if “substantially all outages are distribution-related and virtually none are generation related,” Lazar suggested.

    PG&E’s use of the customer perspective to justify transmission and distribution spending “is more logical,” Lazar said, “because that is where the interruptions – even the biggest ones – are coming from, and not from an insufficiency of generation.”
