Climate Scare Debunked Again

How often have climate change sceptics been told that we're just bloody-minded protesters who refuse to read and accept the volumes of 'climate change' proof available? Too often. Yet I find those who are sceptical tend to be very well informed, questioning individuals who are prepared to listen to all sides of the argument.

Another climate change 'fact' has been debunked by NASA. New NASA measurements of the Atlantic Meridional Overturning Circulation, part of the global ocean conveyor belt that helps regulate climate around the North Atlantic, show no significant slowing over the past 15 years. The data suggest the circulation may have even sped up slightly in the recent past.

The latest climate models predict the overturning circulation will slow down as greenhouse gases warm the planet and melting ice adds freshwater to the ocean. “Warm, freshwater is lighter and sinks less readily than cold, salty water,” Willis explained.

For now, however, there are no signs of a slowdown in the circulation. “The changes we’re seeing in overturning strength are probably part of a natural cycle,” said Willis. “The slight increase in overturning since 1993 coincides with a decades-long natural pattern of Atlantic heating and cooling.”

Now, like many sceptics this evidence will have to be analysed by other climate scientists but it does show the 'science' is not proven, as many believers insist.
