“…[The Fourth National Climate Assessment, Volume II, a congressionally-mandated report from 13 federal agencies] detailing the impacts of climate change across the United States, shows] the clear and present danger that human-caused climate change poses to the American people, especially to communities of color, the elderly and rural communities…[It shows there] is no credible alternative to greenhouse gasses to explain the warming…Temperatures have risen 1.8°F since 1901, and all of that warming (plus some) is due to human activity…Globally, 16 of the last 17 years are the warmest years on record…The planet has 1.1°F of warming locked in, even if emissions were to drop to zero in the short term.

…Economic losses from climate change could reach hundreds of billions of dollars annually, for some sectors. Climate impacts along the coastlines are exacerbating existing social inequities. Communities face difficult questions regarding who will pay for current impacts and future adaptation strategies and if, how, or when to relocate vulnerable communities…The Southeast is expected to lose over a half-billion labor hours by 2100 due to extreme heat…Agricultural crop quality and quantity is projected to decline across the U.S. due to increased flooding, temperatures, drought and other climatic changes...In the Midwest, corn crop yields could decrease by up to 25 percent by mid-century...The economic value of timber is expected to decrease by up to $788 billion by the end of the century due to changes in forest composition…In 2010, heat stress was estimated to have lowered annual U.S. dairy production by $1.2 billion…Global warming and acidifying oceans are already harming the $200 billion fishing sector…” click here for more

By 2100, annual acreage burned could increase by as much as 6 times. Historically, the U.S. has spent an average of $1 billion a year to fight wildfires. In the first eight months of 2017, costs exceeded $2 billion…Rising temperatures are reducing snow-to-rain ratios, leading to significant differences between the timing of water supply and demand…[and] Atlantic hurricane activity has increased…

Climate change is upsetting coastal ecosystems, threatening fisheries, the tourism industry, public safety, and human health. Continuing coastal impacts will worsen existing social inequities as vulnerable communities reckon with adaptation…Sea levels have risen 8-9 inches since 1880, three inches of which have occurred since 1990. As much as 8 feet of sea level rise is possible by 2100 if greenhouse gas pollution is left unchecked…Even with adaptation measures, billions to hundreds of billions of dollars of additional damages are expected by 2100. Lasting damage to personal property and infrastructure will lead to financial losses and higher insurance premiums…” click here for more
