What happened? A whole lot of fossil fuel bullsh*t and corruption in service of a whole lot of nothing.

It is amazing that 60 years ago, scientists were so crystal clear that burning fossil fuels was raising Earth's temperature.

And yet thanks to Big Oil's decades of lies, today 40% in the US still don't believe global warming is human-caused or settled science, and 30% don't think it's happening!
PROBABLE FUTURE CONTENT OF CARBON DIOXIDE IN THE ATMOSPHERE We can conclude with fair assurance that at the present time, fossil fuels are the only source of CO: being added to the ocean-atmosphere- biosphere system. If this held true throughout the last hundred years, the quantity of CO: in the air at the beginning of the present decade was about 7% higher than in the middle of the last century (see Table 3). Throughout these hundred years, the rate of fossil fuel combustion, and thus of CO, production, continually increased, on the average about 3.2 percent per year. The amount produced in 1962 was almost 25 times the annual production in the mid-1860's. The rate of increase may be accelerating. During the eight years from 1954 to 1962, the average rate of increase was 5%. POSSIBLE EFFECTS OF INCREASED ATMOSPHERIC CARBON DIOXIDE ON CLIMATE One of the most recent discussions of these effects is given by Möller (1963). He considers the radiation balance at the earth's surface with an average initial temperature of 15°C (59°F), a relative humidity of 75 percent, and 50% cloudiness. We may compute from his data that with a 25 percent increase in atmospheric CO, the average temperature near the earth's surface could increase between 0.6°C and 4°C (1.1°F to 7°F), depending on the behavior of the atmospheric water vapor content. The small increase would correspond to a constant absolute humidity, that is, a constant weight of water in the atmosphere. The larger increase would correspond to a constant relative humidity, that is, as the temperature rose, the water vapor content would also rise to maintain a constant percentage of the saturation value. A doubling of CO: in the air, which would happen if a little more than half the reserves of fossil fuels were consumed, would have about three times the effect of a twenty-five percent increase. CARBON DIOXIDE FROM FOSSIL FUELS-THE INVISIBLE POLLUTANT Only about one two-thousandth of the atmosphere and one ten- thousandth of the ocean are carbon dioxide. Yet to living creatures, these small fractions are of vital importance. Carbon is the basic build- ing block of organic compounds, and land plants obtain all of their carbon from atmospheric carbon dioxide. Marine plants obtain carbon from the dissolved carbon dioxide in sea water, which depends for its concentration on an equilibrium with the carbon dioxide of the atmosphere. Marine and terrestrial animals, including man, procure, either directly or indirectly, the substance of their bodies and the energy for living from the carbon compounds made by plants. All fuels used by man consist of carbon compounds produced by ancient or modern plants. The energy they contain was originally solar energy, transmuted through the biochemical process called photosynthesis. The carbon in every barrel of oil and every lump of coal, as well as in every block of limestone, was once present in the atmosphere as carbon dioxide. Over the past several billion years, very large quantities of carbon dioxide have entered the atmosphere from volcanoes. The total amount was at least forty thousand times the quantity of carbon dioxide now present in the air. Most of it became combined with calcium or magnesium, freed by the weathering of silicate rocks, and was precipitated on the sea floor as limestone or dolomite. About one-fourth of the total quantity, at least ten thousand times the present atmospheric carbon dioxide, was reduced by plants to organic carbon compounds and became buried as organic matter in the sediments. A small fraction of this organic matter was transformed into the concentrated deposits we call coal, petroleum, oil shales, tar sands, or natural gas. These are the fossil fuels that power the world-wide industrial civilization of our time. Throughout most of the half-million years of man's existence on earth, his fuels consisted of wood and other remains of plants which had grown only a few years before they were burned. The effect of this burning on the content of atmospheric carbon dioxide was negligible, because it only slightly speeded up the natural decay processes that continually re- cycle carbon from the biosphere to the atmosphere. During the last few centuries, however, man has begun to burn the fossil fuels that were locked in the sedimentary rocks over five hundred million years, and this combustion is measurably increasing the atmospheric carbon dioxide. In the geologic past, the quantity of carbon dioxide in the atmosphere was determined by the equilibrium between rates of weathering and photosynthesis, and the rate of injection of volcanic carbon dioxide. on an earthwide average, both weathering and photosynthesis must speed up when the carbon dioxide content of the air is increased, and slow down when it is diminished; consequently, over geologic time the carbon dioxide in the air must have risen when volcanic activity was high, and must have gone down when volcanoes were quiescent. On a human scale, the times involved are very long. The present rate of production of carbon dioxide from fossil fuel combustion is about a hundred times the average rate of release of calcium and magnesium from the weathering of silicate rocks. As long as this ratio holds, precipitation of metallic carbonates will be unable to maintain an unchanging content of carbon dioxide in the atmosphere. Within a few short centuries, we are returning to the air a significant part of the carbon that was slowly extracted by plants and buried in the sediments during half a billion years.

The US group included eight people, according to one person present. The intimidation included approaching country officials during coffee breaks to warn them they might not be able to transit via the US, or that they and their families could face restrictions on entering the country if they acted against American interests, according to five people at the talks, including two from countries that were directly threatened. US President Donald Trump has branded the framework a “global green new scam tax on shipping”, and in a social media post last month called for it to be blocked.

Just like dealing with the mob (which this is, under Trump).

A clip from the FT article. (H/T @allouryesterdays.bsky.social). Nice post, Doug.
While the Trump administration has made no secret of its disdain for the UN and multilateral organisations, diplomats and experts warned that the behaviour at the IMO crossed a line, with potential long-term consequences for global governance. “It was like the New York street,” said a diplomat from a nation that was threatened with visa restrictions for shipping crews and other penalties, including increased fees to access US ports, if it did not drop its support for the framework. “They went from delegation to delegation ... threatening them. Telling them to go back and speak to their capitals, warning what would happen if they didn’t change their minds,” the diplomat said. A second veteran of IMO meetings said the US tactics had left the entire organisation — usually a forum for technocratic discussion and consensusbased decision making — in a state of “complete shock”. “It’s like dealing with the Mob,” the veteran added. “It’s bully-boy tactics. They don’t need to tell you exactly what they’re going to do to you, just make it clear that there will be consequences.” A State Department official did not address the personal threats to delegates
