Europe Hammered By Winter, Is North America Next?
Then, out of the blue, Europe got clobbered: Over the past two weeks, temperatures in Eastern Europe have nose-dived to -30 degrees Celsius (-22 degrees Fahrenheit). Blizzards and the bone-chilling cold have resulted in the deaths of over 550 people so far, with rooftop-high snow drifts trapping tens of thousands of villagers in their homes and cutting off access to entire towns. It has even snowed as far south as North Africa.

Ancient plants back to life after 30,000 frozen years
Scientists in Russia have grown plants from fruit stored away in permafrost by squirrels over 30,000 years ago.The Institute of Cell Biophysics team raised plants of Silene stenophylla - of the campion family - from the fruit.
Writing in Proceedings of the National Academy of Sciences (PNAS), they note this is the oldest plant material by far to have been brought to life.
Prior to this, the record lay with date palm seeds stored for 2,000 years at Masada in Israel.

Believe it or not, the Sky is Falling
A new paper just published in Geophysical Research Letters
by Roger Davies and Mathew Molloy of the University of Auckland finds
that over the past decade the global average effective cloud height has
declined and that “If sustained, such a decrease would indicate a
significant measure of negative cloud feedback to global warming.”Davies and Molloy are quick to point out that part of the decline from 2000 to 2010 in cloud height is due to the timing and variability of El Niño/La Niña events over the same period, however, there still seems to be evidence that at least part of the decline may remain even when El Niño/La Niña variability is accounted for.

Arctic Is Already Suffering the Effects of a Dangerous Climate Change
ScienceDaily (Jan. 30, 2012) —
Two decades after the United Nations established the Framework
Convention on Climate Change in order to "prevent dangerous
anthropogenic interference with the climate system," the Arctic shows
the first signs of a dangerous climate change. A team of researchers led
by CSIC assures so in an article recently published in Nature Climate Change
These researchers assert that the Arctic is already suffering some of the effects that, according to The Intergovernmental Panel on Climate Change (IPCC), correspond with a "dangerous climate change."
