Cartoonist Randall Munroe at XKCD demonstrates ice age issues.
Of course it was a cartoonist. Where else does one go to find the truth these days, but the cartoons?
XKCD dramatically shows differences in North American cities and their relationship with their local ice sheets, 21,000 years ago. Cartoon by Randall Munroe.
Enric Sala wrote about our disappearing ice for the World Economic Forum — a post worth reading.
Twenty kilometres in 20 years. That’s how much the Ilulissat glacier has retreated as this mighty, flowing river of ice crumbles into the ocean. It sounds like a lot. But I did not fully realize what this meant until we flew over the Ilulissat icefjord. It takes 10 minutes for the helicopter to fly over the amount of ice that has been lost because of global warming – in this glacier alone.
The speed at which the glacier moves has doubled relative to that in 1998. My scientist brain, accustomed to working with numbers and large scales, had a hard time absorbing this information. If I was rationally aware of the consequences of global warming from scientific reports before, now I felt it emotionally. This is what my trip to Greenland with a group of World Economic Forum Young Global Leaders did to us. It made us move from knowing and caring to be desperate to do something about it.
The experience also made us realize that all the international negotiations and agreements to date are not going to help avert the imminent catastrophe. Not even the boldest targets to reduce carbon pollution put forward by the smartest nations are going to move the dial. It’s all an illusion of movement, kind of like Alice in Wonderland’s Red Queen, running and running but not going anywhere.
Truth on ice.
There is a difference, though. Ice thins, gets weaker, and covers less area. As that happens, as the planet warms, the density of denialists does not appear to decrease, at least not fast, and not toward greater understanding and less insanity.
