33 years of climate data show temps well below alarmist prediction
It’s another nail in the long-buried coffin of the “man-made global warming” conspiracy theory.
“Every month climatologists John Christy and Roy Spencer report the latest data from satellite measurements of global average temperatures. This month marks the 33rd anniversary of their data set. On the occasion, the researchers release a longer analysis of global temperature trends…” Reason magazine reports.
The verdict? “Man-made global warming” theorists are the ones belching hot air.
Globally averaged, Earth’s atmosphere has warmed about 0.45 Celsius (about 0.82° F) during the almost one-third of a century that sensors aboard NOAA and NASA satellites have measured the temperature of oxygen molecules in the air.
This is at the lower end of computer model projections of how much the atmosphere should have warmed due to the effects of extra greenhouse gases since the first Microwave Sounding Unit (MSU) went into service in Earth orbit in late November 1978, according to satellite data processed and archived at UAHuntsville’s ESSC.
“While 0.45 degrees C of warming is noticeable in climate terms, it isn’t obvious that it represents an impending disaster,” said Christy.
And where did that warming come from? Human activity?
“Mother Nature” herself.
“Clear net warming did not occur until the El Niño Pacific Ocean “warming event of the century” in late 1997. Since that upward jump, there has been little or no additional warming,” Reason reports.
“Only portions of the Antarctic, two areas off the southwestern coast of South America, and a small region south of Hawaii have cooled. On average, the South Pole region has cooled by about 0.05 C per decade, or 0.16 C (0.30° F) in 33 years. The globe’s fastest cooling region is in the central Antarctic south of MacKenzie Bay and the Amery Ice Shelf. Temperatures in that region have cooled by an annual average of about 2.36 C (4.25° F).”
