Global Warming Intensifying Rainfall
As Britain reels from rainfall of unprecedented intensity [news search], a new scientific study found that heavier rainfall is caused by global warming [more | more2]. The study in the journal Nature found that “more intense rainstorms across parts of the northern hemisphere are being generated by man-made global warming”. Meteorologists agree that the miserably wet British summer of 2007 has generally been caused by a southward shift towards Britain of the jetstream. The new study does not purport to blame any given rain event on climate change (should it?), but it supports the general finding that global warming caused by human emissions is causing increased rainfall [search] — by showing that in recent decades rainfall has increased over several areas of the world, including the mid-latitudes of the northern hemisphere.
This sort of extreme weather response to global heating has long been predicted, but this the first time this link has been made directly. Given an unprecedented string of weather related catastrophes, anyone that does not acknowlege climate change must be a dullard or have investments in fossil fuels. What good is climate science if it preducts climate change produce extreme weather phenomena, but there are no specific events that can be considered as a direct result of the warming? Humanity and the Earth are facing a new type of problem for which they are ill-prepared. By the time there is 100% proof positive that climate change is causing extreme weather, it may well be too late to do anything about it. We need to exercise the precautionary principle and act on the greater than 90% probability it is.
