Arctic and Antarctic

 

I have gathered this information to focus attention on these two danger areas and to enable us to understand the dangers better. The science of many of the processes at work is in its infancy and climate models have so far largely ignored the effects, like the potential for the disasterous release of methane, because they cannot yet be predicted accurately.

 

Please help us to gather this information and assess the dangers.
