One of my favorite blogs, Paul Kedrosky's Infections Greed has a post today on a new company called WeatherBill.
WeatherBill is:
In effect, a tool to allow people to create their own weather-related
short- and long-term insurance policies -- and it will appeal to a
broad swath of companies whose business are weather-affected.
It appears to essentially be a marketplace where people can first evaluate what bad weather costs them in terms of sales, then they can purchase short or long term insurance plans to cover themselves from these losses going forward. On the other side it gives investors the opportunity to own these contracts or create their own that businesses can purchase. It appears it may definitely take some work to build up an efficient market, but I believe that the rapidly changing and increasingly sporadic weather makes a service like this definitely worth watching.
A persistent kink in the jet stream pattern typically sets up in these cases, pumping cold air from the pole down to one region, and warm subtropical air northwards into an adjacent region. However, that is not the case this year. Land areas in huge areas of the Northern Hemisphere, including most of Asia (Figure 4), have temperatures well above normal. This is something I've never seen before--there's almost no cold Arctic air to be found.Why is this scary, and potentially dangerous to have such warm winters?
The Arctic Ice Cap has shrunk by about 20% since 1979, and at the end of November this year, the amount of sea ice in the Arctic was about 2 million square kilometers less than had even been seen in any previous November. December has also seen the lowest sea ice coverage for any December on record. All this exposed water provides a huge source of heat and moisture in the Arctic that retards the formation of the usual cold air masses over the adjacent regions of Canada and Siberia... the record low sea ice in the Arctic is probably a significant contributor to this winter's record warmth.He ends with:
I expect that the unnaturally warm winters we've experienced the past two years in the U.S. will become the norm ten years from now--and may already be the new norm.I know I've been posting a lot about the excessive warmth we've seen this winter, but I can't really believe it. I've only been a "weather geek," for about 15 years but I do know for sure that there certainly has been nothing like this since I've been alive, and most likely since anyone reading this has been alive. It seems to me that climate change is not going to be something that happens gradually over hundreds of years, but more likely something that happens very quickly in a rapid chain reaction. The melting of the Artic ice caps is happening and will (as mentioned above) prevent normal cooling in winters, which will melt more ice caps more quickly, which will mean warmer winters, which will melt more ice caps even more quickly...etc. It appears to be happening.
I guess the obvious question I need to ask myself is, what can I do personally to make a difference?
