New NRC report on the state of the polar regions

GlacierThe 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.

Arctic beluga whales and narwhals had a close relative in Pliocene waters

Beluga whales and narwhals live solely in the cold waters of the Arctic and sub-arctic. Smithsonian scientists, however, found that this may not have always been the case. They recently described a new species of toothed whale and close relative to today’s belugas and narwhals that lived some 3-4 million years ago during the Pliocene in warm water regions.

Arctic ice has had a good winter

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

Arctic warming cold winter hypothesis loses one year

And it also loses a study, but then it gains two… We’ll just admit a small prejudice. Are gut feelings allowed in science?

Today´s paradox: European cold winters associated with Arctic warming – and positive(!) AO

Warming in the Arctic would increase the chance of cold winters in Europe and parts of North America and Asia. There have now been three consecutive studies that reach this conclusion in as many years. That means it is about … Continue reading

Today’s paradox: Russian ice is melting, water becomes saltier

As the climate changes, so does the face of local meteorology. In the Arctic it appears the Beaufort high is gradually making place for increased dominance of low pressure systems, leading to a more dominant positive phase in the Arctic … Continue reading

Drop in CO2 heralded the onset of Antarctic glaciation

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
