I only call them as I see them and you really don't need to look very hard.

This is not a binary situation. There is wide spectrum that includes those seeing how obvious man-made climate changes is and also seeing how obvious some are using it to push a IMO anti-capitalist, fear mongering, end of the world if we don't act today, BS agenda.
It's getting harder and harder to keep an objective and realistic stance on this topic due to all the political noise created around it.

And I see lots of money, grift, and power being traded, at the expense of ordinary humans.

The whole thing is BS.

IMO it's getting easier and easier as the effects grow with each year. Climate Change is a proxy 'battle' in a larger and much older ideological 'war IMO. Truth (as defined by the warring factions) is the first casualty so I will try to just stick to actual evidence and let the cards fall.

Attacking those who dissagree with you with loaded words like "denier" clearly demonstrates you've chosen your faction and have no interest in discovering truth.

Yes, I've chosen the majority faction of scientific evidence instead of a ideological truth from either polar opposite side.

If I really wanted to attack you on this subject, you would have heard it in much stronger terms. The disagreement is not with me or you, IMO the disagreement is with actual evidence. I long ago decided that's the way to truth back during the old “global warming is not happening” phase of this issue as we move forward (when the old battle was lost) to the "solutions don’t work” phase part of the battle.

A 350kW DC superfast charger. A standard rack of 'pumps' working to recharge cars would take the energy of streets of houses (the USA average kWh per day was 29).
But Dr Edward Brightman, lecturer in chemical engineering at Strathclyde University, said that while rapid charging is useful for long journeys, the real barrier to electric vehicle take-up still lay in the supporting infrastructure.

"We need more batteries, and we need them fast."

Translation:

SEND MORE MONEY!
Yeah, well I had a breakthrough in battery technology last night too. I now have a battery that charges itself, from itself.
Check back in 99 years or so or until you drop dead, whichever comes first :)

Funny they can make an almost completely noiseless CPAP machine to keep a human being breathing for 8 hours straight without a hitch ... but an EV can't be charged without making a fuzz

A major EV charger location is equivalent to a sizable electrical substation.
https://electrical-engineering-portal.com/audible-substation-noise
Equipment noise levels may be obtained from manufacturers, equipment tendering documents, or test results. The noise level of a substation power transformer is a function of the MVA and BIL rating of the high voltage winding. These transformers typically generate a noise level ranging from 60 to 80 dBA.

Transformer noise will “transmit” and attenuate at different rates depending on the transformer size, voltage rating, and design.

Few complaints from nearby residents are typically received concerning substations with transformers of less than 10 MVA capacity, except in urban areas with little or no buffers. Complaints are more common at substations with transformer sizes of 20-150 MVA, especially within the first 170-200 m (500-600 ft).
