In the North Atlantic, sea surface temperatures have been increasing by around 0.3C per decade over the last 40 years, according to the Met Office.

Climate change is not expected to increase the number of these storms globally. But a warming planet is, bringing heavier rainfall and a higher likelihood of coastal flooding.

This year's above average forecast is expected for two main reasons.Firstly, sea surface temperatures are above average across most of the tropical Atlantic, although they are not as extreme as this time last year.Warmer seas provide the fuel source for hurricane growth as they track westwards across the Atlantic.

– which makes it harder for Atlantic hurricanes to develop - is not expected this year, according to NOAA.Neutral or weak La Niña conditions – which favour Atlantic hurricanes - are considered more likely, though this early on it is difficult to say.

Other conditions have to be right for hurricanes to develop, and those aren't possible to predict months in advance.

Localised air movements and even the amount of dust in the atmosphere can play important roles in shaping whether these storms develop or not.If the measure is ultimately allowed, it could deliver a devastating blow to the university, where more than a quarter of students are from overseas.
