#ExxonKnew about #ClimateChange almost 40 years ago

A new investigation shows the oil company understood the science before it became a public issue and spent millions to promote #misinformation

By Shannon Hall on October 26, 2015

"One thing is certain: in June 1988, when NASA scientist #JamesHansen told a congressional hearing that the planet was already warming, Exxon remained publicly convinced that the science was still controversial. Furthermore, experts agree that Exxon became a leader in campaigns of confusion. By 1989 the company had helped create the #GlobalClimateCoalition (disbanded in 2002) to question the scientific basis for concern about climate change. It also helped to prevent the #USA from signing the international treaty on climate known as the #KyotoProtocol in 1998 to control #GreenhouseGases . Exxon’s tactic not only worked on the U.S. but also stopped other countries, such as #China and #India, from signing the treaty. At that point, 'a lot of things unraveled,' Oreskes says.

"But experts are still piecing together Exxon’s misconception puzzle. Last summer the Union of Concerned Scientists released a complementary investigation to the one by InsideClimate News, known as the Climate Deception Dossiers (pdf). 'We included a memo of a coalition of fossil-fuel companies where they pledge basically to launch a big communications effort to sow doubt,' says union president Kenneth Kimmel. 'There’s even a quote in it that says something like ‘Victory will be achieved when the average person is uncertain about climate science.’ So it’s pretty stark.'

"Since then, Exxon has spent more than $30 million on #ThinkTanks that promote ClimateDenial, according to #Greenpeace. Although experts will never be able to quantify the damage Exxon’s misinformation has caused, 'one thing for certain is we’ve lost a lot of ground,' Kimmell says. Half of the greenhouse gas emissions in our atmosphere were released after 1988. 'I have to think if the fossil-fuel companies had been upfront about this and had been part of the solution instead of the problem, we would have made a lot of progress [today] instead of doubling our greenhouse gas emissions.'"

#JamesHansen says: "I told you in 1988 that the #climatecrisis will come to this level, you didn't listen, now we're on the edge of the abyss", he says what comes next will be a world we've never experienced before. #GlobalWarming #heatwaves

‘We are damned fools’: scientist who sounded #ClimateAlarm in 80s warns of worse to come

#JamesHansen, who testified to Congress on #GlobalHeating in 1988, says world is approaching a ‘new climate frontier’
https://www.theguardian.com/environment/2023/jul/19/climate-crisis-james-hansen-scientist-warning #ClimateCrisis #AndNowYoureGoingToBelieveUs?

"[Climate scientist #JamesHansen] said the record heatwaves that have roiled the US, Europe, China and elsewhere in recent weeks have heightened 'a sense of disappointment that we scientists did not communicate more clearly and that we did not elect leaders capable of a more intelligent response'.

"'It means we are damned fools,' Hansen said of humanity’s ponderous response to the climate crisis. 'We have to taste it to believe it.'"

https://lnkd.in/ejfZ8Ejh #JamesHansen #aerosolen #Klimaatalarm #ExtinctionRebellion #Cliteur Zondag 28-05-2023 Opschudding onder klimatologen. James E. Hansen, Leon Simons en anderen publiceerden een nog niet-peerreviewed artikel 'Global Warming in the Pipeline', waarin hij een forse versnelling van de opwarming voorspelt. In 2050 zouden we daardoor al op een schrikbarende 2,0 graden Celsius boven pre-industrieel niveau komen. Ze waarschuwen voor een termination shock. Dat slaat..

“Equilibrium global warming including slow feedbacks for today’s human-made greenhouse gas (GHG) climate forcing (4.1 W/m2) is 10°C, reduced to 8°C by today’s aerosols”

#jameshansen

"we conclude that continuation of GHG emissions along the path that the world is on will lead to shutdown of the overturning (North Atlantic and Southern Ocean) circulations this century and sea level rise of several meters on a time scale of 50-150 years."

The latest #EcoShock podcast has a good non-technical summary of the recent #JamesHansen paper on "Global #warming in the Pipeline" and the possibility of a 10°C increase being already baked in.

Very concerning messages are emerging about the return of El Niño and its impact on global temperatures in 2023/24.

Good couple of #blogposts by @kenrice on a recent paper by #JamesHansen et al I'd missed about #ClimateSensitivity.
I tend to agree about the #IceSheet point, it's hard to extrapolate #ECS from #palaeoclimate on #milankovitch timescales because the whole world was *very* different place

And here's the source, the reference straight from the horse's mouth, or actually the Hansen's mouth. I'm talking about Dr. James E. Hansen. I was wrong when I said 30 years ago. It was 40 years ago.

@edavies
If you go too far upstream to energy generation, you run into the "socialise the cost" issue— all pay despite some people being more aggressive consumers. Its best to have taxes on luxury and high-impact goods. If that is what #JamesHansen writes about, then we agree.

We in #Australia once had a #luxuryGoodsTax (20%). It was abolished when #GST (10%) was brought in

Does he write for a publication not (#)cheatingHumanity?

On #ClimateChange, We’re Entirely Out of Margin

In 1959, when humans began measuring the #CO2.
In 1988, when the #NASA scientist #JamesHansen first alerted the public to the climate crisis, that number had grown to three hundred and fifty p.p.m., which we’ve since learned is about the upper safe limit. Even then, though, we had a little margin, at least of time: the full effects of the heating had not yet begun to manifest in ways that altered our lives.
