The 2012 figure for the year so far stands at 14.45°C. If that were the figure for the full year, it would be cooler than 1998 (14.51°C) and most of the years since then (full listing from the Met Office here).
there is now some admission even from the hardest climate hardliners that something may be going on which is not understood. Dr Peter Stott of the Met Office, head of Climate Monitoring and Attribution, had this to say while announcing the 2012-so-far-number:
"We are investigating why the temperature rise at the surface has slowed in recent years, including how ocean heat content changes and the effects of aerosols from atmospheric pollution may have influenced global climate."
Meanwhile, according to some research from Princeton:
At current melt rates, the Greenland ice sheet would take about 13,000 years to melt completely, which would result in a global sea-level rise of more than 21 feet (6.5 meters).
Page provides some context:
Put another way, in that scenario we would be looking at 5cm of sea level rise from Greenland by the year 2130: a paltry amount. Authoritative recent research drawing together all possible causes of sea level rise bears this out, suggesting maximum possible rise in the worst case by 2100 will be 30cm. More probably it will be less, and there will hardly be any difference between the 20th and 21st centuries in sea level terms.
