The depth of this winter's chill will depend on the 'Greenland Block' – a high-pressure bulldozer that holds up warmer winds from the equator and steers Arctic air toward the Deep South.
2010 was one of the deadliest years on record for coral reefs. The Caribbean Sea just outside the Cancún climate conference offers evidence of global warming's negative effect.
Israeli officials are racing to contain wildfires that began in northern Israel on Thursday morning, prompting the evacuation of 17,000 and a rare request for international assistance.

Summer thaw was underway on the fringe of eastern Greenland when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite passed overhead and captured this image on July 13, 2007. Inland (l.), snow and ice make a white blanket, while closer to sea (c. and r.) the annual snow has retreated from much of the rocky coastline and from the surface of some glaciers, which appear slightly gray. In the fjords, meltwater carrying finely ground sediment, crushed by the movement of glaciers over rock, colors the water turquoise.
If November and December temperatures stay relatively warm, 2010 could capture the record for warmest year, an early analysis shows. This year has also been marked by extreme weather events.
A Tokyo earthquake measuring 6.9 hit Japan Monday afternoon. The quake affected a broad swath of the country.
Europe: Man-made lights highlight particularly developed or populated areas of the Earth's surface, including the seaboards of Europe. Large cities are often located near rivers or oceans so that they can exchange goods cheaply by boat. This image is a composite of hundreds of pictures made by the Defense Meteorological Satellite Program (DMSP), which currently operates four satellites carrying the Operational Linescan System (OLS) in low-altitude polar orbits.
That's the good news heading into Cancun global warming talks Nov. 29. The bad news is that the carbon dioxide emissions aren't likely to stay down for long.
Meteorologists continue to marvel at the megastorm that blew through the Midwest Tuesday. Several peculiar weather events combined to make the storm historic.
The Pacific Northwest will be colder and wetter than usual, while the South and California will be warmer and drier, says the US National Weather Service.
