Czech Physicist Dr. Lubos Motl: "Well, the actual history of CO2 followed Scenario A most closely – the CO2 emissions kept on rising at a slightly accelerating rate. So you can see that Hansen predicted the warming trend about 3°C per century. The actual observed trend from the 1980s (well, early 1980s) has been about 1.3°C per century according to satellite and slightly below 2°C per century according to weather stations. Although we didn't really stop CO2 emissions at all, the temperature was growing almost exactly like Hansen's scenario in which the CO2 concentration becomes constant after 1988!"
"There's nothing "worse" about the climate of 2018 relatively to the climate of 1988."
Climatologist Dr. Pat Michaels and Meteorologist Dr. Ryan Maue:
"Thirty years of data have been collected since Mr. Hansen outlined his scenarios—enough to determine which was closest to reality. And the winner is Scenario C. Global surface temperature has not increased significantly since 2000, discounting the larger-than-usual El Niño of 2015-16. Assessed by Mr. Hansen’s model, surface temperatures are behaving as if we had capped 18 years ago the carbon-dioxide emissions responsible for the enhanced greenhouse effect. But we didn’t. And it isn’t just Mr. Hansen who got it wrong. Models devised by the United Nations Intergovernmental Panel on Climate Change have, on average, predicted about twice as much warming as has been observed since global satellite temperature monitoring began 40 years ago..."
"Several more of Mr. Hansen’s predictions can now be judged by history. Have hurricanes gotten stronger, as Mr. Hansen predicted in a 2016 study? No. Satellite data from 1970 onward shows no evidence of this in relation to global surface temperature. Have storms caused increasing amounts of damage in the U.S.? Data from the National Oceanic and Atmospheric Administration show no such increase in damage, measured as a percentage of gross domestic product. How about stronger tornadoes? The opposite may be true, as NOAA data offers some evidence of a decline. The list of what didn’t happen is long and tedious."
Via UK Guardian: Jame Hansen’s long list of culprits for this inertia are both familiar – the nefarious lobbying of the fossil fuel industry – and surprising. Jerry Brown, the progressive governor of California, and the German chancellor, Angela Merkel, are “both pretending to be solving the problem” while being unambitious and shunning low-carbon nuclear power, Hansen argues.
James Hansen: ‘Promises like Paris don’t mean much, it’s wishful thinking. It’s a hoax that governments have played on us since the 1990s.’
There is particular scorn for Barack Obama. Hansen says in a scathing upcoming book that the former president “failed miserably” on climate change and oversaw policies that were “late, ineffectual and partisan”.
Hansen even accuses Obama of passing up the opportunity to thwart Donald Trump’s destruction of US climate action, by declining to settle a lawsuit the scientist, his granddaughter and 20 other young people are waging against the government, accusing it of unconstitutionally causing peril to their living environment. “Near the end of his administration the US said it would reduce emissions 80% by 2050,” Hansen said.
'The companies that could be sued are known as the “carbon majors,” Hansen says. These are the 100 companies who have been the source of more than 70 percent of the world’s greenhouse gas emissions since 1988. ExxonMobil, Shell, BP, and Chevron are listed as among the highest carbon-emitting, investor-owned companies. This legal action is comparable to the successful tobacco industry lawsuits that resulted in billions of dollars in settlements, he adds. In fact, climate lawsuits are already happening. Last year, a Filipino government body called the Commission on Human Rights of the Philippines accused 47 carbon majors of human rights violations because of their role in climate change. Three California coastal communities sued 31 fossil-fuel companies in July. Last month, four municipalities on Canada’s west coast asked Chevron, Exxon, Shell, and others to pay their share of the climate costs those communities are facing. There is now even a nascent movement called Climate Law in our Hands that helps communities go after these carbon-emitting companies.'
