Tornadoes in Winter

Thursday, February 7th, 2008

I did a little research to see if the phenomenon of deadly tornadoes during the winter months is normal or related to warming. There are differing opinions but the consensus is that tornado season can start in January in the Southern states and extremely dangerous tornadoes are not uncommon during winter months. Dot Earth has more info and stats on the frequency of dangerous storms that show little definable connection between warming and these weather phenomena.

Here in Rochester (NY) the winter pattern is much different than in the past and it is definitely a warming pattern. However this has not resulted in better weather- it has been different weather. We’ve had a lot of big fluctuations in temperatures. Tuesday it was 55 degrees F, this Sunday we will be lucky to see 10 degrees. Last week in a ten minute period the temps dropped 35 degrees.

The effects of these swings are extreme: very high winds (70 mph gusts during that rapid drop), heavy ice storm-style icing which we seldom saw before the end of March and heavy, wet lake affect snows. Most of us would much rather have a 25 degree dry humidity powder snow day anytime over 35 degree damp slush weather which has been the story most of this winter.

Brad Pitt funds sustainable housing designs for New Orleans

Monday, December 3rd, 2007

Brad Pitt enlisted a bunch of architects to design houses for the Lower Ninth Ward in New Orleans. They were to be green, 1200′ sq. ft. and buildable for $150,000.
A lot of interesting designs that wouldn’t be bad around here (Rochester).

I could live in those.

20 foot storm surge in UK and Europe

Saturday, November 10th, 2007

A huge storm in the North Atlantic brought storm surges as high as 20 feet yesterday to Europe and the UK. Barriers on the Thames were closed to protect London. This is the biggest surge since 1953. Fortunately no one was hurt and damage was minimal.

The issue here is that climate change doesn’t simply mean higher ocean levels. Even a slight rise in levels, combined with more violent weather due to warming, will mean more and more of these storms in regions where they have been very rare in the past. Because there was no historical record of major storm surges, these coastal areas are highly developed and support dense populations. The potential for future destruction is much higher because of this.

This is a classic environmental feedback loop. Warming generates storms, higher ocean levels mean higher surges. Interestingly, the same storm caused unstable snowpack conditions in Switzerland, creating dangerous avalanche conditions.

A perfect storm: water disasters strike North America

Tuesday, October 23rd, 2007

Residents of Atlanta, Georgia may open their taps in the next month and have nothing come out. 14,500 lawn and landscape workers have been laid off because there is no water. The state has done nothing to deal with the crisis except for asking residents to ‘take shorter showers’. (!) Real estate developers have built like crazy and were never required to prove there was enough water to support the development.

North Carolina today asked its residents to halve their water use through Halloween so the state can evaluate its ability to handle a water crisis.

300,000 Southern Californians (update- make that 500,000) flee fires that cannot be fought because of Santa Ana winds, extreme drought conditions and large amounts of dead, dry brush. Thousands of homes will be lost.

The Great Lakes are down seven inches from their normal levels due to very dry winters. Each inch of loss means that 8000 tons of raw materials that drive manufacturing in the region cannot be shipped this year because of the danger of shipping running aground.

In Canada’s West glaciers are rapidly disappearing. These glaciers supply the lakes and rivers that are the primary water sources for huge farms. The permafrost on the mountains is melting so that snow runoff, instead of running into the streams, is being absorbed by the ground, accelerating the losses to the water sources.

The Colorado river is drying up. It is the only supply of water for the entire South West including much of Mexico as underground aquifers are no longer viable. Yet there have been 300 hundred golf courses built in the region in the last five years.

These stories are all current today. In each case there is no man-made solution, no emergency action we can take to fix the problem. Nor are we doing anything about this- not a thing. We are building housing like crazy in areas that have no regional water sources. A study released today shows that carbon emissions worldwide have risen drastically since 2000, much faster than expected. Again, we are doing nothing.

No matter how rich we are here in North America, we cannot sustain life without water. We have no infrastructure to produce water where there is no natural source and building such an infrastructure would mean mustering hundreds of billions of dollars and a solid political consensus that understands the emergency nature of the problem. Not much chance of that taking place.

I have friends who tell me they can’t read this blog too often because it is depressing. I have held off on blogging because there is too much climate change news every day. It is obvious that this thing is upon us full force yet there is still denial at the very center of power. We have to reach these people somehow and get their attention. Perhaps having dry faucets in the thousands of McMansions around Atlanta will wake a few people up.
