As the days shorten and the summer sun is slowly setting under the horizon, the frost is returning to the Arctic and American scientists make up the balance of what has turned out to be an unprecedented melting season. The … Continue reading →
Do you recall the big Arctic melting records of 2005 and 2007? Probably you do. Scientists had noticed the Arctic ice was on a declining trend and predicted this would continue under expected climate change. But no one expected the … Continue reading →
Ocean level rise is known as one of the most disquieting effects of global warming, with more than three billion people living on the coast or less than 200 kilometres land inward and one tenth of the world population living … Continue reading →
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.
There has been much speculation about what exactly caused the end of the last ice age 10,000 years ago. Some say the Earth’s orbital changes were the cause, others say it was an increase in atmospheric CO2. But although a … Continue reading →
Each year at the end of winter the Arctic sea ice reaches its maximum extent. Although unsurprisingly this ice maximum receives less media attention than the annual sea ice minimum in September, combining the two gives a better representation of … Continue reading →
