Climate change far less serious than 'alarmists' predict says NASA scientist - 30th July 2011

Climate change is far less serious than ‘alarmists’ predict, an eminent NASA scientist has said.

Dr Roy Spencer, who works on the space agency’s temperature-monitoring satellites, claimed they showed ‘a huge discrepancy’ between the real levels of heating and forecasts by the United Nations and other groups.

After looking at the levels of radiation in the atmosphere over the past ten years, he believes the Earth releases a lot more heat into space than previously thought.

This means carbon dioxide emissions do not trap as much heat or force temperatures up as much as global warming bodies fear.

Dr Spencer, a climatologist at the University of Alabama, said his satellite readings between 2000 and 2011 show far smaller temperature rises than six climate models which are used by international governments and corporations to predict changes to our climate in the future.

He said: ‘The satellite observations suggest there is much more energy lost to space during and after warming than the climate models show.

'There is a huge discrepancy between the data and the forecasts that is especially big over the oceans.’

However critics say his research is over too short a period to draw conclusions and ignores other factors.

Dr Spencer is the first scientist to examine the data from Nasa satellites in relation to climate change.

He has long believed the build-up of hot air produces more clouds, which have a cooling effect on the Earth, counteracting global warming to some extent.

However his study, published in the journal Remote Sensing, does conclude that the limited heating he has found remains an ‘unsolved problem’. Read More
