Warmists say they won’t disbelieve models unless ‘pause’ lasts another 20 years!
AFP reports:
Over the past 50 years, the mean global temperature rise was 0.12 degrees Celsius (0.2 degrees Fahrenheit) per decade, slowing to an average 0.05 C (0.09 F) per decade over the past 15 years.Half of the slowdown could be attributed to volcanic eruptions, whose particles reflect sunlight, and a bigger-than expected drop in heat from the Sun’s changing activity cycle, said a summary of the report.
The other half is attributed to a “cooling contribution from internal variability”.Laurent Terray with the French computer modelling agency Cerfacs said the term is used to explain a shift in the way heat is distributed between land, sea and air.Still unclear is what causes the variation or determines its duration.
“We know that this kind of episode, of a decadal length or thereabouts, can occur once or twice a century,” said Terray.“If it (the present one) continues for two more decades, we may start to think that the computer models are underestimating internal variability.”
