The Land and Sea Surface Temperature data record an
accelerated temperature increase. Here, from Hadley
Centre, are the global surface temperatures from 1850
to 2010. Note that data for the last 17 years are all
above the linear trend. This is the result of an
accelerated warming.

of global warming rates starting in 1952.
