The U.S. National Research Council has just released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions.
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
Heard about Sunday’s big climate news? We are afraid it is actually twice as bad as most media reports suggest:
To notice something is going on with the world’s ice sheets, you could measure melting water runoff, glacier retreat or use satellites and GPS to measure ice volume decline. Just like measuring sea level rise and temperature this all adds … Continue reading
For about 100 million years all sorts of animals roamed the then subtropical North and South poles. But then suddenly some 34 million years ago during the Eocene everything changed when temperatures fell dramatically in only a 100,000 year timespan, … Continue reading
Is it the albedo effect? Is it increased ice dynamics? Dutch researchers add a third player to better understand why Arctic melting is happening as fast as it is. The clue is in the winter polar night skies, they say.
Yes, indeed, we’re a couple of days late bringing you the news. But this could be an important update to our Arctic melting coverage. It’s feedback-driven (after all), American and French researchers say.
In our first ice age riddle a couple of days ago we looked at the link between CO2 rise and ice retreat, after the last ice age had reached its max, some 18,000 years ago.
Today is September 14 2011, the day the Climate Reality Project makes a stand against the ‘new normal of climate denial.’ Over 24 times zones there will be 24 climate presentations in which public attention will be focused on the … Continue reading
