UN climate change report dismisses slowdown in global warming

The Earth has changed in “unprecedented ways” since 1950, the U.N. says, and its scientists are 95 percent certain that humans are responsible.

 

Yet the planet has largely stopped warming over the past 15 years, data shows -- and a landmark report released Friday by the U.N.’s climate group could not explain why the mercury has stopped rising.

 

Global surface temperatures rose rapidly during the 70s, but have been relatively flat over the past decade and a half, rising only 0.05 degrees Celsius (0.09 degrees Fahrenheit) per decade according to data from the U.K.’s weather-watching Met Office, a trend current models of the world’s climate have been unable to predict. A draft of the report leaked in early September acknowledged that trend and put it bluntly: We simply can’t explain it.

 

“Models do not generally reproduce the observed reduction in surface warming trend over the last 10–15 years.”

 

But a final version of the report released Friday morning by the U.N.’s Intergovernmental Panel on Climate Change (IPCC) strips out the failure of models and explains away the downward trend.

 

“Due to natural variability, trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends,” the new report reads.

 

A later reference suggests volcanoes, oceans and solar activity may have affected the warming, although the IPCC said it wasn't confident in that finding.
