Pollution affects the ocean in many different ways. One of these is that it causes hurricanes. A recent increase in the intensity of tropical cyclones in the Arabian Sea may be a side effect of increasing air pollution over the Indian sub-continent.

Traditionally, prevailing wind-shear patterns prevent cyclones in the Arabian Sea from becoming major storms, but the weakening of the winds has enabled the formation of stronger cyclones in recent years–including storms in 2007 and 2010 that were the first recorded storms ever to enter the Gulf of Oman.

First it was drought, then it was massive floods–now Australia faces a hurricane that is estimated to be twice the size of hurricane Katrina and at least as powerful. The Australian Meteorology Bureau issued the following warning: ‘This impact is likely to be more life threatening than any experienced during recent generations." The largest typhoon so far recorded was supertyphoon Tip, which struck Guam in 1979 with 200 mph winds. Yasi has so far displayed winds of 180 miles per hour and is expected to strengthen over the next 24 hours.read more

Summer is hurricane season, which seems far away right now. But it never hurts to be prepared, because hurricanes do more than devastate the landscape–they’re bad for pregnant women and their unborn children as well. Exposure to hurricanes can cause significant adverse fetal distress risks and can lead to longer-term health care problems for affected children. These risks contribute previously hidden human and economic costs to the impacts of severe hurricanes.

There seem to be more destructive hurricanes every year. Atlantic hurricane activity gets stronger and weaker over a cycle of several decades, and we’ve been in the active part of that cycle for the last 15 years. Scientists now say they have found a way to forecast hurricanes in the Atlantic–not just for the upcoming year, but for several years in the future.read more
