Changes in our climate caused Sandy's malice

01 November 2012

The ferocity of Superstorm Sandy is directly linked to climate change (News, October 31).

Man-made global warming has increased the temperature of the sea surface around the world.

This leads to Sandy having more energy to suck up and, in turn, become more ferocious.

A study that uses accurate tide measurements since 1923 removes any doubt that superstorms are stronger in warmer years.

The number of warm years has increased over the past century and especially in the past decade.

For every increase of one degree fahrenheit, US superstorms are likely to get 2% stronger.

Those who talk about solar energy being 'more expensive' than fossil fuels are not factoring in the expense of climate change.
