There is no scientific evidence that an asteroid is going to send us the way dinosaur but there is plenty of evidence that climate change caused by rising greenhouse gases levels are a threat to our way of life. We are only starting to see those changes which will gradually increase through the end of this century and almost surely will continue for centuries to come. Conversion to EVs will certainly help mitigate climate change but it will not stop it. We will have to adapt. The amount of adaption is going to depend on what we accomplish in this century.
The power grids can support all EV charging needed to convert all autos and small trucks to EVs. That is not the problem is not the grids. We will have to change the way we manage the power grids. Currently states limit sales to grids and 35% of our power plants in the country are not connected to grids. Access to regional grids vary by state. There are also legal limitations within the grids that prevent energy from flowing where it is needed. With increasing generation of power by solar cells and wind and better management of the grids we should be able to avoid building any new power plants to support EVs till after 2050 when 30% of the vehicles and light trucks are projected to be EVs. In the second half of the century we will probably need more power plants but the number will be dependent on growth of EVs and alternative power generation.
There are people who SAY there is scientific evidence that climate change caused by AGW is threatening our way of life but almost all of those have jobs, incomes, positions, reputations, credentials that DEPEND on them saying that. The person who questions AGW is generally forced out in a hurry.
Most scientists whose jobs, reputation, income etc. do not depend on them saying that aren't saying that.
Almost all government, education, scientific institutions, MSM, social media, entertainment, and big business is now controlled by those on the hard left and these can severely limit what the average American is allowed to see or hear. And of course what they want us all to hear is that climate change is our largest existential threat. (Or maybe it is second behind white supremacy depending on who you talk to.)
But I also see people who have zero reason to lie about it say they've seen data manipulated to produce a certain conclusion, data omitted that would change perspectives of conclusions, etc. etc. I see the 'scientific' predictions come and go again and again and again with nothing happening and they just move the goal posts further into the future.
It is getting far more difficult for the average citizen to get all information necessary to have an informed opinion now that Google, Edge, et al are severely limiting what their search engines produce for us to see.
I see that despite the intense efforts to go green, green and greener, those efforts have made not one whits' difference in the climate.
I see most of those leading the charge to combat climate change almost universally living their personal lives as if nothing at all was happening with the climate. That makes it really hard to believe they are honestly concerned.
All this convinces me that we should keep studying the issue but we are seriously misdirecting funding and policy when what we should be doing is helping people improve their lives in the climate that exists and be developing ways for us to adapt to an inevitably changing climate with minimal disruption of lives and quality of life.
Certainly forcing people to prematurely give up fossil fuels as they are currently doing is a certain prescription to increase massive poverty and misery around the world. And I'm more and more confident that climate change presents far less of an immediate challenge to human kind than does that asteroid. The odds are way in favor of the asteroid.
