This summer is what global warming looks like: Increased average temperatures, forest fires, extreme weather episodes. Climate change is gradual and a matter of averages. Different parts of the globe will be affected differently. We could have a cold wet summer along the way.

Human beings have opened the spigot and are pouring carbon dioxide and soot into the atmosphere in such amounts over a short time that it is unprecedented in earth’s 4.5 billion year history– and that is what is causing the warming, which is just beginning. In the worst case, where we burn all the coal and oil and gas in the world, over the coming centuries we could have an average increase of 9 degrees Fahrenheit, with the entire world being tropical including Antarctica and with a sea rise that would submerge a third of the world’s present land mass.
