I UNDERSTAND THE MECHANISM!!!
Now I do happen to have the advantage of having studied physics in general and climate physics in particular, but the required knowledge to understand the greenhouseeffect is highschool level and most of my (14-19 year olf) students are capable of understanding it as well.
There are a lot of things about Global Warming that can/need to be debated and researched better, from the particular effects on certain regions of the world, to the exact nature/danger of tipping points such as the Permafrost or the Ice shields of Greenland and the Westantarctic and of course the required response (i.e. CO2-Tax vs. a cap and trade-system vs. investment in new tech etc.). 10 Years ago I myself was part of a research group studying a particular effect, that contributed to cooling!!! the climate, today the results of that study are part of every up-to-date climate modell.
What is not up for debate, is that
a) The greenhouse effect is real, and that a doubling of the CO2-Concentration leads to a warming effect of around 2°C.
While Climatemodels are constantly being refined and updated those updates are about effects that impact the climate on one or two orders of magnitude less then what CO2(and to some extent CH4) contribute. It is still important to incorporate them, after all the climate is a "complex system" and small changes might have big consequences, but nothing ever added will negate this primary driver of our changing climate.
This is NEITHER NEW KNOWLEDGE NOR DEBATLABLE and anyone I have ever encountered to say otherwise was either clearly not educated on the subject or had a political agenda.
In this view I am not alone, any physicist knowledgable on the subject would agree so much so that the high arbiters of scientific achievements, i.e. the Nobel Commitee for the science prizes(=/= peace prize) this year chose to give the Physics Prize to Syukuro Manabe and Klaus Hasselman, who in the 1960s and 70s!!! developed methods show the double CO2 = 2°C as well as methods to clearly show how to distinguish between the natural variability of the climate and the impact of human behaviour.
b) While the climate has always changed it has never done so this quickly. This is important, because while nature can reasonably adapt to changes over the course of thousand or tens of thousads of years, it can not do so withing decades, meaning at our current course we are heading for a mass extinction event.
Now what makes me sad and sometimes angry is that image of green voter/ ecofriendly people as naive. While quite a few of them are, that percentage is about the same as in any other group of humans. But the real naivitee is to think that our economy can go on as it is. The constant more more more of our current type of capitalism ( not advocating for communism here, there are other types of market based system around then what we currently have) is simply not sustainable for more then (maybe) the next few decades.
Ps. Gotta love thejuicemedia
pps. for those fluent in german, this is an Interview with this years Nobellaureate Klaus Hasselmann, listen to the 30-60s starting at 1:20 and remember that the guy knew most of what he found out by 1980!!!https://www.tagesschau.de/multimedia/video/video-927783.html
