7 SIMPLE PROOFS OF CLIMATE CHANGE (Part 2)

7 ways to shut down a climate change denier; Comprehensive rebuttals to contrarians' pseudo-scientific explanations why global warming is just a myth (continued below)

John Rennie, December 18, 2013 (Scientific American)

Challenge 3: "...Global warming stopped a decade ago; Earth has been cooling since then..." -- "...Given the extended duration of the warming trend…a decade’s worth of mild interruption is too small a deviation to prove a break in the pattern…[E]xperts found no true temperature declines over time…"

[Challenge 4:] "...The sun or cosmic rays are much more likely to be the real causes of global warming..." -- "...Astronomical phenomena are obvious natural factors to consider…because those seem to have been major drivers of the ice ages and other climate changes before the rise of industrial civilization…[But] there is insufficient evidence that enough extra solar energy is reaching our planet to account for the observed rise in global temperatures…[And] the effect of CO2 and the other greenhouse gases…amplify the sun’s warming…[T]here do not seem to be clear long-term trends in the cosmic ray influxes or in the clouds that they are suppose to form…[and they do] not explain (as greenhouse explanations do) some of the observed patterns in how the world is getting warmer…” click here for more
