G8 agrees to limit temperature rise to 2 degrees Celsius above pre-industrial levels by 2050

Fantastic, no need to worry about that global warming thing after all, the G8 have solved it,.....

BTW, How bad would 2 degrees be?

The common view is that 2 degrees gives a 50/50 chance of runaway global warming - a bit like playing Russian Rulette with a two chamber gun and with your grandchild the potential victim.

The target that we need is to get CO2 below 350. http://www.350.org/

That's ok. Not having had any children, I'm unlikely to have grandchildren. Actually it's probably not ok, as not many of the politicians who decided that will be around in 2050 to face the consequences

A paper in Nature last April suggested that to give us only a 25% change of exceeding 2C warming, a 1 in 4 chance of going over 2C, we need to limit CO2 emissions to 1 trillion tonnes between 2000 and 2049. That's going to be tough given than during 2000-2006 we emitted 234 billion tonnes!

Hmmmm, if true, that is a bit depressing.

We're lucky at the moment as we're in a period of low solar activity which is supposed to last for the next 30 years. Mind you, we've still had temperatures at near record levels in Europe already this year. So, is Global Warming stronger than the sun's cyclic influence?

Can we not all move to Siberia and Antartica?

Nice and warm........but a little bit wet.

Having read 6 degrees, my question was meant in jest.

Is the map representative of 9 meters rise or just a general image?

Since no one at the meeting will be alive in 2050, or in power 2019, its relevent how?

IanG, I don't think it's representative of any particular sea level rise, just a striking picture from a design blog.

FYI Here's the page I got it from Link

FWIW I think we've already set in motion a climate beyond +2degC - it's about adaptation now.

What happened to Ireland?
