Using proxy evidence to study past climates helps us put the 20th century warming into a broader context, as well as to better understand the climate system and improve projections of future climate.

The researchers applied statistical tools designed to identify structural changes in time series data over time, commonly called changepoint models, to four sets of global mean surface temperature ...

A temperature reconstruction from ice cores of the past 1,000 years reveals that today's warming in central-north Greenland is surprisingly pronounced. The most recent decade surveyed in a study, the ...

At high elevations of the Greenland Ice Sheet, the years 2001 to 2011 were 1.5 °C warmer than in the 20 th century and represent the warmest decade in the last thousand years A temperature ...
