NASA GLOBAL WARMING SCIENTIST FLIP FLOPS ON FOSSIL FUEL FUSS
UPI ARCHIVES AUG. 17, 2000: James Hansen a leading scientist considered to have been instrumental in sparking serious debate over global warming suggested this week that emissions of carbon dioxide (CO2) from burning fossil fuels are not the main culprit in global warming, and that the world should instead focus on reducing other pollutants, such as chlorofluorocarbons and nitrogen oxides (NOx) to reduce the globalwarming threat. Dr. James Hansen from the National Aeronautic & Space Administration’s Center for Climate Systems Research this week argued that those other pollutants – and not CO2 from burning oil and coal – are the real culprits in global warming. Hansen adds that reducing those emissions instead of CO2 would eliminate many of the political hurdles that slow efforts to curb global warming. “We argue that global warming in recent decades has been driven mainly by non-CO2 greenhouse gases such as chlorofluorocarbons and (NOx), not by fossil fuel burning,” James Hansen had stoked serious debate on global warming by calling on Congress to address the issue in landmark testimony delivered to Capitol Hill in 1988.

Global warming may be happening more quickly than previously thought, according to a new study by a group of researchers including former NASA scientist James Hansen, whose testimony before Congress 35 years ago helped raise broad awareness of climate change.

The 2025 study warns that the planet could exceed 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, of warming this decade, compared with the average temperature in preindustrial days, and that the world will warm by 2 degrees Celsius by 2050. When countries signed the landmark Paris Agreement in 2015 to collectively fight climate change, they agreed to try and limit global warming to “well below” 2 degrees Celsius and aim for 1.5 degrees.
“The 1.5 degree limit is deader than a doornail,” said Dr. Hansen, now the director of the Climate Science, Awareness and Solutions Program at Columbia University, during a news conference on Thursday. The 2 degrees goal could still be met, he said, but only with concerted action to stop using fossil fuels and at a pace far quicker than currently being applied now in 2025.

They have programmed AI to combat the evidence of climate fraud. Global temperatures did not increase until the IPCC was established in the late 1980’s…just a coincidence?
Dr. Hansen, who predicts that at least one new global temperature record will be set by the decade’s end, believes the second possibility more likely. But, citing the atmosphere’s natural variability and large measure of chaotic behavior, he said it would not be clear for several years whether the change in regional climates was more than temporary.
It will be ”extremely interesting” to watch, he said. This was one of his last public comments he made in 1996 befor he resurfaced again in 2000 when he said that burning fossil fuels was not the cause of global warming and blamed another trace gas as the culprit.
I like your tongue twister heading…Fuss..”an excessive display of anxious activity”, “needless or useless bustle”. You nailed it.
The greenhouse gases Nitrous Oxide, PFCs, SF6, CFCs and halons do not react with OH in the troposphere.These gases are destroyed in the stratosphere or above, mainly by solar ultraviolet radiation (UV) at short wavelengths (<240 nm)are long-lived.
The newspapers could not get enough of James Hansen in the eighties and mid ninties but lost popularity when the Hockey Stick crowd, led by CRU East Anglia and promoted by the WMO, lowered global temperatures in 1995 by one degree Celsius to pave the way towards a little more than 15 C+ to line up with NASA earth planetary temperature data.
