Global Warming Will Intensify Hurricanes and Tornadoes

hurricanesThe lastest news regarding the scientific debate about how, and whether global warming will affect the world’s most violent storms, is that there will be stronger storms – dust devils and water spouts, tornadoes and hurricanes. Or at least this is what us predicted by a team from the University of Michigan.

In the Swedish Journal Tellus A, the University of Michigan team of well-respected and well-credentialed scientists, improves on the predictions of computer models which stimulate the effects of climate change. Their predictions state that for every 3.6 degrees F the Earth’s surface temperature warms, the intensity of of these storms could increase by a few percent.

Nilton Renno lead author of the team said that "It shows us that climate change could lead to increases in how efficient convective vortices are and how much energy they transform into wind. Fueled by warmer and moister air, there will be stronger and deeper storms in the future that reach higher into the atmosphere."

Last May, NOAA suggested that the hurricanes in the Atlantic will grow stronger but will occur less often due to global warming. However, contrary to NOAA’s suggestion, a prominent hurricanes researcher – who had previously supported NOAA’s suggestion – is now second-guessing some of his own ideas.

In 2007, there were fewer hurricanes than expected, though there were rapidly intensifying cyclones in the Atlantic Basin. The World Meteorological Organization also retired three killer storm names – Dean, Felix and Noel.

Early predictions for 2008 are for an above-average year filled with frequent storms and intense hurricanes. Storm season officially starts June 1. The second named storm of the season became its first major hurricane – Hurricane Bertha.

To date, 2008 tornado activity remains above average. Tornadoes have killed more people than any other year since 1998 and is on track to be the deadliest ever recorded.
