The Columbia Glacier is about 54 kilometers long, 5 kilometers wide and more than 1,000 meters thick in some places.
La Nina could help trigger dramatic temperature swings across the central and eastern United States and increase the likelihood of drought across the Southeast and Southwest.
The hoary breath of this now-famous media star is already being felt in Colorado, as several major storms have passed through during the month of November, leaving Denver dwellers unseasonably chilled.
While fog can occur under a variety of circumstances, the northward-surge phenomenon–especially common in the summertime–has vexed California forecasters for years.
The study checks the NCAR model’s reliability by simulating past climates and comparing its results to geological data, such as pollen deposited in lake sediments at the time, fossilized, and recently retrieved from lake cores.
The Arctic tree line is sensitive to climatic change and is expected to be one of the first major vegetation boundaries to register greenhouse warming if it is indeed occurring.
The ozone hole that forms over Antarctica each spring is believed caused by a cascade of chemical reactions that begin on the cloud particles at temperatures of minus 118 F.
Is this pattern of change a manifestation of the global warming and related climate change associated with increases in greenhouse gases in the atmosphere? Or is this pattern a natural decadal-timescale variation?
