The claim that we need to "invest into science" is outright bullshit. We don't need more investment into climate change science - we already know what to do to mitigate climate change and we have known it for decades (hell there is an article from over a hundred years ago that warns of the dangers of CO2 emissions [2]): ban ICE vehicles and coal power plants, promote public transit, massively restrict other uses of fossil material, get rid of mass animal farming, prevent profiteers from burning down the Amazon rainforest.
The problem is, politicians won't do anything because they are either bought out by the fossil fuel industry that is at the top of the CO2 emitter list [1] or because they are afraid of telling their voters that the only way to stay on track regarding climate change will be a drastic cut in their quality of life.
