"_All_ the studies are measuring the same tendency : the temperature is rising"

There could be lots of reasons for that. Anyway, the temperatures were not always rising, clear temperatures rise was observed in 1930-40s and in 1980-90s. Cooling in 1960-1970s. And yes, prediction has to be precise. If a model predicts rise of 3K in 100years, and you measure 1.3K - your model is wrong. It's even more wrong if you don't take into account any of the natural cycles, even if prediction is accidentally correct.

LOL, no. Denmark used 67.5TWh gasoline and diesel fuel last year, due to better efficiency of the electric drivetrain it's equivalent to roughly 20TWh of electricity. Denmark also used 46TWh electricity last year, so they would need to increase their production by 43.5%. It's quite high actually, for Germany the same figure is just 31% (190TWh and 610TWh). All data can be found here https://www.statbank.dk/ENE2HA.

Your numbers are off. Tesla requires 9kg of lithium per 10kWh. If 85kWh model has in reality 95kWh, then you'd need 85kg lithium per car. World reserves of lithium are roughly 16 million tons, so, it would suffices for a bit under 200 million Teslas.

Lithium production was 43000 tons last year, which would produce 500.000 cars, even if we wouldn't need lithium for anything else.

2200lb for gas, 3000lb for the engine, 700lb for the transmission. Say 7k lb total. Compare this now to the electric one. The battery alone would weight 33k pounds. Engine and transmission would add another 2k. 5 times more than ICE. The battery would also cost $200k.

It's about battery, not about electricity. You will need 20-40% of additional electricity production to convert all ICE cars to electric, it can be done today. But the battery can't compete with ICE on equal terms.
