In a world of increasing Tropical Storms and Hurricanes, the causes are scientifically pointing towards man made climate change.
The U.N. Climate Panel says that a build-up of greenhouse gases, in the atmosphere, mainly from burning fossil fuels, has created a Global Warming trend that will cause more heatwaves, floods and droughts, rising sea levels, tropical storms and hurricanes.
A report in the scientific journal Nature indicates that the last decade has seen, on average, more frequent hurricanes than any time in the last 1,000 years. The last period of similar activity occurred during the Medieval Warm Period.
The study is not definitive, but it is a unique piece of work that combines an analysis of sediment cores from inland lakes and tidal marshes with computer modeling and finds a “striking consistency” between the two, the authors suggest.
“You don’t want to go into the business of predicting the future without knowing the history, which does tell us what’s possible and tests our understanding,” says Richard Alley, a Pennsylvania State climate change researcher. “When people build models to predict hurricanes in the future, one way you know it works is to wait 100 years and say, ‘See.’ Or you run it against the previous 1,000 years.”
The new report, was written by Penn State University paleoclimatologist Michael Mann and several colleagues.
