The current cold snap may be more than just a blip. Two leading climate researchers have found evidence that the Earth may be heading into a cooling period which could last 20 to 30 years. Better keep those snowshoes handy!
Have you notice that this year is a bit different than these past few years? There is climate changes and I have found out that there is many places that have unusual weather going on. To find out what kind of weather is happening at other people's location I posted up a question on answers.yahoo.com (http://answers.yahoo.com/question/index;_ylt=Ai6ehEHIOirNwIoaUPUQaEAazKI...) to see if the weather is really a sign or a warning of 2012.
Courtesy Della XiongFor an example. In Minnesota, on Spring there wasn't as much rain as it usually did every year. September was the month that has the most rain. It seems as if September was Spring instead of Fall. And going towards October their were a couple days that have snowed, it was unexpected. It's like the weather shifted a month forward. So for me the cause of 2012 could be the weather, but I wasn't sure about it so I ask another question "Is the changing of the weather a sign of 2012? on answers.yahoo.com to get peoples opinion. (http://answers.yahoo.com/question/index;_ylt=Agak5C7_ZvFnrKhAwJySvp0azKI...) The answer that I get was no. Most of them said the changing weather is just a symptoms of global warming and climate changes that is caused by human and this made me think that they could be right about it. So what is your opinion? And what do you think of the weather? Do you think the weather has anything to do with 2012?

Well, summer is officially over. The Weather Service switched to fall on September 1. The rest of the country likes to wait until the day after Labor Day. (The folks who hold out for the equinox are delusional, and best ignored.) So, it's time to update our on-going study comparing summer temperatures to winter temperatures.
For those of you just joining us, last February Buzz blogger extraordinaire Candace noted that the winter of 2008-2009 had been unusually warm. She asked if this meant the following summer would also be warm.
Well, I went to the website of the National Space Science and Technology Center, which very conveniently records the temperature for each month going back to December 1978. I crunched the numbers and found that, yes, there was a connection. Though summer temps fluctuate year-to-year, about half of that fluctuation can be tied to changes in winter temps.
Armed with this information, we anxiously awaited the temperature record from summer 2009. The results are in, and...
...well, this was obviously part of the other half. The winter of 2008-2009 was the 4th warmest in the recording period. The summer of 2009, however, was dead smack in the middle -- 16th out of 31. So disparate were these results that they actually brought down the average for the entire study period: the impact of winter temps on summer temps is now down to just 45%.
Still, for something as complicated as weather, that's a huge impact. So, while the winter-summer connection can't predict what will happen in any given year, over the long run it does still hold true.
Tune in next year for another exciting update!
Courtesy NOAAThe names for the 2009 hurricanes were announced a few days ago by the National Hurricane Center (NHC). The NHC has a list of names they draw from, that reuses names every six years or so, but if a storm is particularly bad a name will be retired. There are no "Q" or "U" names and they go alphabetically so when they get to Danny you'll know that's the fourth of the season. The names for 2009 are:
Ana, Bill, Claudette, Danny, Erika, Fred, Grace, Henri, Ida, Joaquin, Kate, Larry, Mindy, Nicholas, Odette, Pete, Rose, Sam, Teresa, Victor and Wanda.
(Interesting the names "Pete" and "Rose" are in succession.)
So far this year we're up to Claudette. Ana is old news already with the National Hurricane Center announcing yesterday that the storm had weakened so much they were no longer tracking it. Claudette is also weakening, but it had the distinction of being the first tropical system to reach land yet this season. Third in line is Bill, who has already become a category 3 hurricane.

Courtesy Mark RyanAn oddball surprise storm caught the city of Minneapolis and other parts of the Twin Cities metro area completely off guard yesterday.
Courtesy Mark RyanThe National Weather Center was ambushed as well, and no warning of the tempest was issued.
Courtesy Mark RyanNothing's been officially confirmed but Minneapolis residents reported sighting cloud rotation, tornadoes, and hearing the roar of wind as a storm swept through downtown and South Minneapolis.
Courtesy Mark RyanHundreds of the city's trees were knocked down by the storm. I was at the Science Museum for a meeting when the warning sirens sounded so on the way home I drove into the affected area to see for myself.
Courtesy Mark RyanI just happened to have a pocket camera with me (I just bought it over the weekend) so I took some photos of the damage in one small area of South Minneapolis near the intersection of Portland Avenue South and East 43rd Street (I used to live near the neighborhood). Because the storm came on without any warning and much of it under the cover of heavy downpour, the weather service's usual storm spotters weren't in place to report on conditions or damage. Investigators are on site today to determine if the culprit was a small tornado (or tornadoes) or straight line winds. The last tornado to go through Minneapolis was back on June 14, 1981. I remember that one well.

Iowa, Illinois, Indiana, Ohio, West Virginia and Pennsylvania set all time records for cold in July while Michigan, Wisconsin, Missouri and Kentucky had their 2nd-coldest July ever recorded.
What is really weird is that in spite of this record cold
The global average went from normal in June to the second-hottest July on record. USA Today
For the global average temperatures to reach near record highs in spite of the central USA's record cold, it must have been really hot somewhere. If you look at this map you will see that the hotter than normal areas are near the South Pole.

How strong an El Niño will eventually develop and how long it is likely to last is not yet known. Learn more about El Niño in 2009 in ScienceNow Daily News.
That's right, folks, whether you wanted him around or not, El Niño has come, and he's going to break your head open! (Climatologically speaking he will.)
One way to describe El Niño might be to say that it's a global weather phenomenon associated with an upwelling of warm water off of the Pacific coast of South America, occurring every two two five years, which causes all sorts of oddness around the world, from droughts in Australia to major flooding in South America, to heavy rains and increased wave erosion in the Pacific Northwest.
Another way to describe El Niño might be this:
(Actually, I'd encourage someone to write something better than this wimpy little post on El Niño. There's a lot to say about it, and it affects billions of people around the world. Check it out, teach us something we didn't know.)
How Accurate Are The Weathermen on T.V.?
Have you ever gone outside inappropriately dressed for the weather because a weatherman said it was supposed to be 80 degrees and it was 60 degrees? I have, but weathermen are not to blame. For the most part they are 80-90% accurate with their predictions. But like I said they’re PREDICTIONS not a 100% guarantee. As the weather is forever changing, meteorologists use high technology such as dopplar radar, satellite pictures, barometers and other technology to predict weather. They can never be exact because weather is not an exact science. So I took my experiment outside and i measured the humidity, wind, and temperature then I looked up a few weather stations around the Twin Cities to see whose predictions were closest to the predictions I got. They were all similar about 80 degrees and partly cloudy(which it was outside).With humidity 35-40%. The only thing very different was the wind. I got 1mph and the weather stations got 10mph.
