Science says a slowing in global warming is just an illusion caused by bad data

The latest scientific analysis suggests the much talked about global warming slowdown during the first 15 years of the 21st century didn’t actually happen but was an illusion created by inaccurate data.

Researchers at the US National Oceanographic and Atmospheric Administration (NOAA) say thousands of updated and corrected temperature observations show that temperatures did not plateau.

The rate of warming has been at least as high as that seen in the last half of the 20th century, they say in a study published in the journal Science.

Numerous studies have been done to explain the possible causes of the apparent fall off in the global warming rate.

In the latest research, Thomas R. Karl of NOAA and colleagues looked at possible causes of an apparent decrease in the upward trend of global surface temperatures since 1998, a phenomenon which has been dubbed the global warming “hiatus”.

Using updated and corrected temperature observations taken at thousands of weather observing stations over land and as many commercial ships and buoys at sea, the researchers show that temperatures didn’t plateau as thought.

The authors say the IPCC (Intergovernmental Panel on Climate Change) statement of two years ago — that the global surface temperature has shown a much smaller growth trend over the past 15 years — is no longer valid.
