That's because climate change is not the real issue for the Left. It is only the "stated" issue. This is why they have spent decades and decades trying to get people to agree with them and haven't been successful.
Of the top 25 things that people want their government officials to deal with or solve, climate change doesn't even make the list.
The real issue is their wet dream of a socialist revolution. If they can destroy the capitalist, free enterprise economic system by eliminating fossil fuels which powers it, then they can install their socialist/communist big government system to replace it. Simple as that.
They don't care about the climate, saving the earth, environmentalism, reducing CO2, recycling, etc, etc, etc. They only use it as a ruse or a vehicle to try and scare people into accepting their argument.
In other words,they’re evil bastards/bastardettes.
... socialist revolution. If they can destroy the capitalist, free enterprise economic system ... they can install their socialist/communist big government system to replace it. Simple as that.
The real dream of 1940.
“Controversial problems [between Germany and Russia] did not, in my opinion, exist anywhere along the line from the Baltic Sea to the Black Sea and to the Far East. In addition, despite all the divergencies in their views of life, there was one thing common to the ideology of Germany, Italy and the Soviet Union: opposition to the capitalist democracies in the West.”—Julius Schnurre, Nazi trade rep to Russia.
