Wondering why most people doesnt care about nature anymore.
Not realizing that they set their own time bom.
In the latest study, published in the journal Science, a team led by Peter Webster, of the Georgia Institute of Technology, analysed all the satellite records of hurricanes and typhoons since 1970.
“What we found was rather astonishing,” he said. “In the 1970s, there was an average of about 10 Category 4 and 5 hurricanes per year. Since 1990, the number of Category 4 and 5 hurricanes has almost doubled, averaging 18 per year.”
Judith Curry, his colleague, said: “Category 4 and 5 storms are also making up a larger share of the total number of hurricanes. Category 4 and 5 hurricanes made up about 20 per cent of all hurricanes in the 1970s, but over the past decade they have accounted for about 35 per cent of these storms.”
The findings, Dr Webster said, could be a result of global warming, though he said much more research was needed.
