Quotes of the Week

"We can try to put a nice face on it. We can try to soften it, but the reality is that there is no statistically significant hiatus, and there never has been," says Harvard science historian Naomi Oreskes.

Science challenges claim that global warming took a hiatus by Marianne Lavelle, National Geographic, June 4. 2015

"Adding in the last two years of global surface temperature data and other improvements in the quality of the observed record provide evidence that contradict the notion of a hiatus in recent global warming trends," said Thomas R. Karl, L.H.D., Director, NOAA's National Centers for Environmental Information. "Our new analysis suggests that the apparent hiatus may have been largely the result of limitations in past datasets, and that the rate of warming over the first 15 years of this century has, in fact, been as fast or faster than that seen over the last half of the 20th century."

NOAA's National Centers for Environmental Information (NCEI) is the merger of the National Climatic Data Center, National Geophysical Data Center, and National Oceanographic Data Center as approved in the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. From the depths of the ocean to the surface of the sun and from million-year-old sediment records to near real-time satellite images, NCEI is the nation's leading authority for environmental information and data.

Comments 1 to 1:

  1. The so-called "hiatus" only appeared if you used 1998 as the starting point. Starting with 1997 or 1999 gave completely different pictures of the warming trend. That's why I never bought into it.

    To me the 1998 starting point was always a big sign in glowing neon letters reading "Phony Hiatus".
