New fed data shows no stop­ping or slow­ing of global warm­ing


Global warm­ing has not stopped or even slowed in the past 18 years, ac­cord­ing to a new U.S. gov­ern­ment fed­eral study that re­buts doubters who’ve claimed that that heat­ing trends have paused.

Sci­en­tists at the Na­tional Oceanic and At­mo­spheric Ad­min­is­tra­tion read­justed thou­sands of weather data points to ac­count for dif­fer­ent mea­sur­ing tech­niques through the decades. Their cal­cu­la­tions show that since 1998, the rate of warm­ing is about the same as it has been since 1950: about two-tenths of a de­gree Fahren­heit a decade.

The so-called hia­tus has been touted by non-sci­en­tists who re- ject main­stream cli­mate science. Those claims have res­onated; two years ago, the United Na­tion’s In­ter­gov­ern­men­tal Panel on Cli­mate Change felt the need to ex­plain why the Earth was not heat­ing up as ex­pected, list­ing such rea­sons as vol­canic erup­tions, re­duced so­lar ra­di­a­tion and the oceans ab­sorb­ing more heat.

One key to claims of a hia­tus is the start date: 1998. That year there was a big tem­per­a­ture spike; some of the fol­low­ing years were not as hot, though even hot­ter years fol­lowed in 2005, 2010 and 2014, ac­cord­ing to NOAA, NASA and tem­per­a­ture records kept in Eng­land and Ja­pan. This year is on pace to break last year’s global heat record.
