The study is published in the journal Nature, the British recovered from the unusual to see heavy rain in some areas more than 1 month’s decline in rainfall in the space of several hours. Dr. Peter Toth, climate scientist at the University of Reading and co-author of the paper, said: “This document is understandable, there are a large number of human activities affect global rainfall patterns, including increased precipitation in the north of 50 degrees north latitude, In this area, including the United Kingdom.

“The wet winter in the United Kingdom is expected that this will lead to more extreme precipitation, while summer is expected to be drier. But it may be based on climate change, there will be increased, even in extreme precipitation generally dry.” Recent events related to abnormal Weather conditions, with tropical ocean. The biggest problem in the UK is a great uncertainty about what will happen in the future of extreme rainfall. ”

Dr. Francis Zwiers of the Canadian Climate Center model in Toronto, and his colleagues compared records of global rainfall between 1925 and 1999, a global network of climate history, focusing on the 40 degrees north latitude and between the south and the north of 70 degrees . They pointed out that the focus of the precipitation forecast different climate models – some involving only natural trends and others, taking into account the impact of human activities on climate change.

These models, including the impact of human activities proposed by the heavy rains in the northern hemisphere mid-latitudes in the Southern Hemisphere in the deep sea in tropical and subtropical and lower rainfall in the tropical and sub-tropical Northern Hemisphere. When the researchers analyzed the historical record, they found more accurate. Global warming is likely to lead to more rainfall because of the higher atmospheric pressure to improve their water vapor.

Boshialun Myers, climate dynamics group at Oxford University, said: “This is a very important document.” We now know that the external drive as volcanic eruptions affect large-scale precipitation, but for the first time this paper fingerprint of human Impact. This means that the precipitation trends, they may indicate the future to find out more. ”

Dr. Huntingford, of the Center for Ecology and Hydrology, said: “It has been confirmed that the burning of fossil fuels have to change the pattern of rainfall at the global level. Here, we have to understand how they found a significant adjustment into the local changes in extreme precipitation events.

“And after that, we have a project in the future, how to carbon dioxide emissions could lead to further changes in local rainfall. This is a very regional rainfall is expected to be very important to help governments prepare for the possibility of some Circumstances, is a dangerous climate change. “

Although we do not know that most of the media in the U.S. , to record “once in a hundred years flood” West now seems to be every decade, more or less exactly what scientists had expected the heat.

A 2004 analysis by the NOAA National Climatic Data Center found a rise during the 20th century by rainfall, temperature, flow, heavy and very heavy rainfall and high flows in the East. “They found an increase of 14 percent” strong rainfall events “More than 2 inches in a day, and an increase of 20 percent” very heavy rainfall events, “best described as the largest Deluge-4 centimeters in a day. These rains are extremely exactly what was expected by warming comprehensive and scientific models.

Indeed, 2007 saw the second most extreme rainfall over the United States in the historical record, according to the NCDC climatic extremes Index (CEI). Here is a land of the percentage of the country (or two), much higher than normal proportion of precipitation derived from extreme 1-day precipitation events (extreme, which is equal to the higher percentile of tenth Deluge):

I do not know that our government has maintained an index extreme weather? Why do you have? The media does not write about it.

U. S. extreme climate index was created expressly to take a complicated subject ( “multiple climate change and multidimensional in the United States”) and to make them easier to understand for citizens and policy makers. As far in 1995, the analysis by the National Climatic Data Center showed that during the 20th century, the United States has suffered a statistically significant improvement in a variety of extreme weather events, which hopefully heating in general as more – and more – precipitation. Analysis concluded that the chances were only “5-10 percent” this increase was due to other factors that global warming, such as natural climate variability. “And since 1995, the climate has become more extreme .

I have followed this issue, the link between climate change and extreme weather events very closely – and yet, in 2006, we have not seen a single mention of the index in the media, or even a scientific paper on its initial For more than a decade. Global warming may be a hot topic, and in 2006 was the second year ever more extreme, but try a search on Google News “extreme weather Index” (the quotation marks) – do not get to all matches.

Story after story appearing in the mainstream media have no connection with any extreme weather, global warming and disconnected from man-made, a trend that eventually all our lives. The media should do a better job.
