Global Warming 'Pause' Didn't Happen, New Study Confirms
Global Warming 'Pause' Didn't Happen, New Study Confirms
Jan 17, 2024 3:35 PM

An independent study has confirmed previous findings from the U.S. government that there has been no pause in global warming, a common argument made by those who deny the continuous presence of climate change in recent decades.

In 2015, NOAA adjusted a set of temperature readings to take into account changes in how ocean temperatures have been measured since scientists began studying changes in the climate. This adjustment riled a House committee member and others who claimed data was altered to show rising temperatures. NOAA's scientists were then subpoenaed by the House Science Committee, and members then complained that the agency wasn't responding quickly enough to their requests.

The new international study showed the same increase in temperatures NOAA found: about two-tenths of a degree Fahrenheit per decade since 2000, according to the study's lead author,Zeke Hausfather of the University of California, Berkeley. The scientists used data from satellites, buoys and other marine floats to draw their conclusions.

"Our research confirms that NOAA scientists were right," Hausfather said. "They were not in any way cooking the books."

NOAA adjusted past data to take into account old measurements by ships that often recorded temperatures from their engine rooms, where heat from the engines skewed the data. Buoys and satellite data don't have such artificial warming, Hausfather said.

In 1990, about 90 percent of the ocean temperature readings were done by ships, now it is about 85 percent by the more accurate buoys, Hausfather said.

Scientists Andrew Dessler of Texas A&M University and Kevin Trenberth of the National Center for Atmospheric Research, who weren't part the original study or the more recent one that confirmed its conclusions, called both accurate.

"This paper further allays any qualms that there may have been scientific errors or any non-scientific agendas," Trenberth said in an email.

Officials at the House Science Committee did not respond to repeated requests for comment.

Hausfather's study was published Wednesday in the journal .
