Climate change first ‘went viral’ exactly 70 years ago
"But it was in early May, 1953, at a meeting of the American Geophysical Union, that Canadian physicist Gilbert Plass – who had been corresponding with Callendar – told the gathered scientists that trouble was afoot." #cchistory

1.5°C: where the #Target came from – and why we’re losing sight of its importance
"The idea that a “safe” level of warming could be achieved was subjective: current levels were already unsafe for those on the sharpest end of climate change." #cchistory
Climate scientists: concept of #NetZero is a dangerous trap
"Most attention in the mid-1990s was focused on increasing energy efficiency and energy switching (such as the UK’s move from coal to gas) and the potential of nuclear energy. The hope was that such innovations would quickly reverse increases in fossil fuel emissions." #cchistory

Analysis: Which #Countries are historically responsible for climate change?
"In total, humans have pumped around 2,500bn tonnes of CO2 (GtCO2) into the atmosphere since 1850, leaving less than 500GtCO2 of remaining carbon budget to stay below 1.5C of warming." #cchistory
SEC and “Climate-Related Disclosures” – Oil companies knew their “#Scope3” liability decades ago
"Decades before the term “Scope 3” downstream emissions became a term of art, we have a “confidential” Shell Oil document from 1988, wherein we find this shocking line : “However, by the time the global warming becomes detectable it could be too late to take effective countermeasures to reduce the effects or even to stabilize the situation.”" #cchistory
The #LieBrary: Big Oil & Gas knew since the 1960s that their products would have disastrous impacts worldwide.
"Evidence shows that Big Oil & Gas knew as early as the 1960s that their products would lead to climate change, and that it could have disastrous impacts worldwide." #cchistory
Assessing #ExxonMobil’s climate change #Communications
"By the late 1970s, global warming was no longer speculative. The issue was not were we going to have a problem, the issue was simply how soon and how fast and how bad was it going to be. Not if." #cchistory

#SixtyYears of climate change warnings: the signs that were missed (and ignored)
"In August 1974, the CIA produced a study on “climatological research as it pertains to intelligence problems”. The diagnosis was dramatic. It warned of the emergence of a new era of weird weather, leading to political unrest and mass migration (which, in turn, would cause more unrest)." #cchistory
#MargaretThatcher: How PM legitimised green concerns
"On November 8, 1989 [Thatcher] told the UN: "While the conventional, political dangers [...] appear to be receding, we have all recently become aware of another insidious danger. It is the prospect of irretrievable damage to the atmosphere, to the oceans, to earth itself." #cchistory
Judgment on #JamesHansen’s ’88 climate testimony: ‘He was right’
"Our computer climate simulations indicate that the greenhouse effect is large enough to begin to affect the probability of extreme events such as summer heat waves. … It is changing our climate now." #cchistory
