More spectacular junk science from former astronaut Piers Sellers
Sellers claims that “straightforward observed facts” tell us that there was a dramatic uptick in warming in the 20th century. But in 1989 , NOAA said the exact opposite.
Analysis of warming since 1881 shows most of the increase in global temperature happened before 1919 — before the more recent sharp rise In the amount of carbon dioxide In the atmosphere. said Thomas Karl. of the National Oceanic and Atmospheric Administration’s National Climatic Data Center in Asheville. N.C.
While global climate warmed overall since 1891. It actually cooled from 1921 to 1979. Karl said.
Sellers claims that sea level rise and glacial melt is due to humans, which is as dishonest and clueless as a scientist can get. Glaciers have been melting and sea level rising for 20,000 years.
There is no indication that sea level rise has accelerated over the past 150 years.
The 1990 IPCC report said that there was no acceleration of sea level rise in the 20th century.
NASA’s finest people understand that NASA climate science is junk science, but a few charlatans insist on tarnishing the agency’s great accomplishments.
