2011 Climate Change in Pictures and Data: Just the Facts

Peter Gleick

I thought this summary of the latest climate facts at the end of 2011 is useful.  Peter Gleick is a specialist in water and climate change, and is a MacArthur fellow of the National Academy of Sciences in the US. He reminds us here of the key facts of the climate issue, which is useful in the face of having to listen to the endless ideological banter of non-experts with dodgy datasets.

For readers of Forbes, the debate over climate change often takes the form of “tit-for-tat” blogs, conflicting commentary, and dogmatic ideological statements. Lost in this verbal debate are often the simple facts and data of climate change and the immense and definitive global observations of the ways in which our climate is actually changing around us.

So, without much commentary, here are just a few simple and clear pictures (and links) showing how the planet continued to warm and change around us in 2011. And these facts are just part of why all national academies of science on the planet and every major geophysical scientific society agree that humans are fundamentally changing the climate.

The economic costs of ocean acidification and molluscs

[*B.S. means “Bad Science.” What did you think it meant?]

The Earth’s climate continued to change during 2011 – a year in which unprecedented combinations of extreme weather events killed people and damaged property around the world. The scientific evidence for the accelerating human influence on climate further strengthened, as it has for decades now. Yet on the policy front, once again, national leaders did little to stem the growing emissions of greenhouse gases or to help societies prepare for increasingly severe consequences of climate changes, including rising temperatures, changing rainfall patterns, rising sea-levels, loss of snowpack and glaciers, disappearance of Arctic sea ice, and much more.
