Snow covered Palm trees in Las Vegas, Nevada.

When it comes to holiday dinners, many give thanks for beautiful and mild weather. Others give thanks to a blanket of snow on the ground. Still others dare to ask the often debated question about whether having a white Christmas is good or bad. Statistically speaking, depending on which state you live in, you may have a better (or worse) chance than you think to have snow appear near your home on Christmas Day. Check the statistics for your home state now to see if you will have a white Christmas. Just think about it, even Las Vegas gets snow as you can see in the image.

Weather history is an interesting subject. In fact, some people have deicated their lives to showing how weather changes history. From the Salem Witch Trials, to slave revolts in the South, and to the appearance of a winter tornado, storms can and do change lives, if not history altogether. The 10 Deadliest Tornadoes describes some of the worst tornadic storms in US History. Each storm resulted in multiple deaths and millions in damages.

In preparation for the 2009 United Nations Climate Change Conference (COP 15) in Copenhagen December 7-18, 2009, the American Association for the Advancement of Science (AAAS) has opened a photograph exhibit showing climate change around the world. Photographs from the book "Earth Under Fire: How Global Warming is Changing the World," by Gary Braasch will be on display from November 18, 2009 to March 15, 2010. The location is at the AAAS gallery at 12th and H Streets, N.W., Washington, D.C. Admission to the public is free.

What is the purpose of the photo collection? The idea is to show the effects of climate change around the world in a series of photos. The images really do speak louder than any words that are spoken on global warming issues. Globally, there is already evidence for a warming planet. You can visit the online climate change photo gallery at the Earth Under Fire website. The photos are truly stunning, in my opinion. Children and teachers are also invited to participate in the event by checking out the "How We Know What We Know About Climate Change" book online.

Ida was a late-season storm, but her severity was not indicative of a typical late-season tropical storm activity. By November 9th, Ida was reduced to a tropical storm. Wind shear had caused the storm to weaken significantly, but not before causing major damages in Central America. Ida officially made landfall in the United States northwest of Bon Secour, Alabama on November 10, 2009.

The storm later moved on to create a Nor'easter as the remnants of Ida fueled the storm. The result was major flooding along portions of the East coast. According to Dr. Jeff Masters, in some locations record-breaking storm surges were higher than they have been in more than 80 years. Particularly hard-hit were Virginia and northeastern North Carolina with some locations getting over 12 inches of rain.
