Katrina and global warming
From PhiloWiki
- "The more likely cause of hurricane frequency might be found in variations in the Atlantic Ocean Conveyer, the movement of the warm Gulf Stream whose waters, taken from the South Atlantic, replace the cooler, sinking water in the North Atlantic.
- When the Conveyer is strong, O'Brien said, historic records have shown an increase in Atlantic hurricanes; when it is weak, so are the hurricane seasons. For a hurricane to grow stronger, it must keep moving over waters warmer than 80 degrees F, which leads some people to link global warming and the storms. But, he said, there's no scientific evidence to show that such areas of warm water are increasing in size."
