Climate Change Week

Afternoon all!

I have officially and arbitrarily decided that this week on GiA will be Climate Change Week.

I’m assuming that everyone has a pretty good understanding of the science, so I’ll skim over that before delving into the depths of international climate change talks, where it gets seriously complicated.

The science is easy; it’s the politics of it that’s nuts.

First off though, we’ll start with this, a counter that shows you the atmosphere’s current and past carbon dioxide concentration in parts per million (ppm).

It’s a crazy graph and as you can see, we cracked 400ppm earlier this year. The international community has agreed that we need to stay below 2’C of warming above pre-industrial levels in order to avoid a climate that most societies won’t be able to function in.  To stay below this 2’C, we’d need to get carbon dioxide levels down to or below 350ppm.

The 2’C is in itself a bit arbitrary (I’ll explain that in a bit), but it provides a good indicator of how we’re going.

I realise this is pretty sad, so to cheer you up, here’s a video of a baby panda sneezing.
