Two hottest years ever: 2014 will set new world temperature record – and 2015 will break it

El Niño Southern Oscillation index: duration and intensity of La Niña and El Niño years. El Niño is usually defined as a positive temperature anomaly in the east and central tropical Pacific. Another way to express the climate phenomenon is … Continue reading

Arctic sea ice literally halved – September 2012 smashes old record, 3.29 million km2 ice gone

Paleocene-Eocene Thermal Maximum caused by thawing permafrost?

In a new study reported in Nature, climate scientist Rob DeConto of the University of Massachusetts Amherst and colleagues elsewhere propose a simple new mechanism to explain the source of carbon that fed a series of extreme warming events about 55 million years ago, the Paleocene-Eocene Thermal Maximum (PETM), and a sequence of similar, smaller warming events afterward.
