We are in a La-Nina phase at present, so any notion the world is cooling is wrong. Arctic sea ice is at it lowest ever for this time of year.

My big worry is that one or both of the Greenland and W. Antarctic ice sheets starts to collapse. As we saw with other ice sheets this can happen VERY quickly. If sea levels start really rising by more than a few inches a year, politicians may be forced to act. This could take the form of simply turning off coal fired power stations.

A minor correction - arctic sea ice isn't at its lowest ever for this time of year - we'll see how it goes over the summer though.

Hi Big Gav
I wasn't only referring to the extent of sea ice. A crucial factor is that ice that has formed since last September over open water is young and thin; and therefore is much more likely to melt this northern summer.
