The increasing amounts of carbon emissions are pushing hurricanes away from the western Caribbean towards the Northeastern USA

Hurricanes are likely to become both stronger and more frequent in northeastern coast of United States thanks to carbon emissions.

A new research, led by Durham University, UK, has found that weather patterns that cause hurricanes have gradually moved from Western Caribbean towards Northeastern coast of America over the course of few centuries and this shift in weather patterns will lead to increase in intensity and frequency of hurricanes over American Northeast. In contrast, the occurrence of hurricanes has considerably decreased in some parts of the Caribbean. 

The data shows that the deviation in hurricane track is linked to the changes in distribution of heat in the atmosphere – possibly caused by the increasing carbon dioxide emissions.

This inevitably means that New York and other big coastal cities are at high risk of major impacts caused by hurricanes and they need to be better prepared for it.

To reach at the conclusion, researchers reconstructed rain patterns for the western Caribbean dating back 450 years by analyzing the rock formation from cave in southern Belize, Central America.

Researchers found that the average number of hurricanes at the Belize has decreased over time. The reason is hurricanes are moving to the north rather than declining in numbers and manmade emissions in the late 19th century are likely the main driving force behind the shifting of hurricane tracks. 

“Our research shows that the hurricane risk to the Northeastern coast of the United States is increasing as hurricanes track further north,” said study's lead author, Dr Lisa Baldini from Department of Geography, Durham University.

“Since the 19th Century this shift was largely driven by man-made emissions and if these emissions continue as expected this will result in more frequent and powerful storms affecting the financial and population centers of the Northeastern United States.”

In 2012, Hurricane Sandy hit the Caribbean and much of the eastern coastal area of United States, killing hundreds of people and ruining billions of dollars of properties. The study urges authorities to make better plans for mitigating the potential devastating effects of future hurricanes.

Dr Lisa Baldini says. “Given the devastation caused by Hurricane Sandy it is important that plans are put in place to protect against the effects of similarly destructive storms which could potentially occur more often in the future.”
