It is still worth acting to prevent extreme changes, but climate change impacts are already locked in

Climate Change Impacts Already Locked In — But The Worst Can Still Be Avoided  http://www.enn.com/pollution/article/53180    From: University of Exeter 
November 16,  Some impacts of global warming – such as sea level rise and coastal flooding – are already locked in and unavoidable, according to a major research project.

Global temperatures have already risen by around 1°C, and a further 0.5°C warming is expected. The full impacts of current warming have not yet been seen, since ice sheets and oceans take many decades to fully react to higher temperatures.

But more severe impacts can still be avoided if global greenhouse gas emissions are reduced.

More than 50 scientists from 16 institutions in 13 countries have worked on the HELIX project (High-End Climate Impacts and Extremes), which has just finished after four years. The project examined the possible effects of warming of 1.5°C, 2°C, 4°C and 6°C compared to pre-industrial levels.
