Global Warming: Winter Weirding
Scientists are now observing what may become a more frequent pattern, caused by declining northern sea ice - of frigid polar air being pushed out of the arctic regions, while warmer air is drawn to northern areas.

In 1982, Mike MacCracken, then a senior researcher at Livermore Laboratory, gave a lecture at Sandia Labs on the subject of global climate change.
This is the story of how we discovered the planet was warming, and why.
A new study by British and Canadian researchers shows that the global temperature rise of the past 15 years has been greatly underestimated.
Scientists think the amount of methane emitted to the atmosphere from freshwater ecosystems will increase as the climate warms, triggering further warming.
The fact that global surface temperatures have not increased as much over the past decade as many climate models predict they should have, doesn't necessarily contradict the model predictions at all.
Human greenhouse gas emissions have continued to warm the planet over the past 16 years.
Virtually all of the scientific papers published in 2013 accept climate change.
