recorded temperature data used to establish predictive models to highlight the impact of climate change on the recent weather
exceptionally hot summers, droughts and forest fires that follow are the result of climate change, according to a study of global temperature data recorded by an eminent scientist NASA.
The study uses data recorded temperature, instead of forecasting models, to claim that climate change is responsible for the recent extreme weather events such as drought last year in Texas and Oklahoma, the heat wave in Russia in 2010 and the heat wave in Europe in 2003.
The author of the study and director of the Goddard Institute for Space Studies, Dr. James Hansen, said: "We now know that the chances of these extreme weather events have occurred naturally - not climate change - is negligible. "
statistical data in the study shows that temperature extremes are more frequent and more intense in the world. This does not eliminate the possibility that cooler summers than normal in the future, but it means that the probability of unusually hot summer has increased significantly, according to the report.
By comparing the temperature data for the last 30 years in the past 30 years, Hansen and his colleagues say the data show that extreme temperatures have increased since that affects less than 1% of the total area 10%. Hansen explained that the increasing emissions of greenhouse gases "load the dice", or cause the occurrence of extreme events in temperature most likely.
Hansen is a climate scientist, but also a controversial figure. In an apparent reference to the Holocaust, refers to trains carrying coal to power plants "death trains." It has also been arrested four times during the protests of climate change, but still leave his position in the government.
- Other scientists have had mixed reactions to the study. Dr Myles Allen, head of the climate dynamics group at the University of Oxford, said the study results are "broadly in line" with the new offerings. But questioned the authors' interpretation of the data, in particular the idea that recent heat waves must have been a consequence of global warming due to the likelihood also very small.
- "It is very difficult to quantify with certainty the absolute probability of a weather event occurring in a hypothetical pristine environment: the public understands that extreme weather events occur, and the rarest and most extreme event more difficult to quantify the probability of this happening in any given year, "said Allen. The study was carried out before the record heat this summer, which had a devastating drought in the Midwest and destructive fires in Oklahoma.
Overall, the month was the hottest of all time in the average temperature of the earth's surface and the average temperature of the planet's land and oceans were the warmest since the fourth record-keeping began in 1880.
Hansen said at a press conference for the fight against climate change must be a global effort to eliminate dependence on fossil fuels in the long term.
Hansen said: "Frankly, it would not be hard to do if you put a fair price on fossil fuels," and came to advocate something like a carbon tax that companies must pay a fee to consider the use of fossil fuels.
