If calling for action based on science rather than corporate interest makes someone a demagogue, then the political system is profoundly sick
Actions based on claims that political opinions and positions are science is indeed demagoguery. Every attempt to model our climate falls woefully short. The East Anglia model has been used for about 15 years to inform government decision-making; it stopped working about 14 years ago. All of its claims, and every claim that came before it, have proven wrong. There were supposed to be tens of millions of climate refugees five years ago, Madison Avenue in New York was supposed to have become an underwater wonder ten years ago, and most of Florida was supposed to have disappeared fifteen years ago.
This isn't as bad as the Imperial College of London model of COVID-19, but it's close. The lockdowns resulting from the model's false predictions will ultimately kill more people than the virus. Both, though, were successful in causing unneeded panic. Lockdowns did increase the power of authoritarian regimes. We knew enough about respiratory viruses to catch the fact that the models were wrong before they were released.
Global glacier volume is unchanged; it's only the retreating glaciers that are given press, according to the world's best glaciologists who are, unsurprisingly, located in Iceland. Sea ice is unchanged since the 1970s. Polar bear populations keep going up, and the nature of greenhouse gases reflect back into space more energy than received means that there is no future hockey stick.
