What a sales pitch.

it is all about the rapidness of the change, which happened with volcanic activity that wiped out 85% of all living species back then and is similar to the rapid change we are responsible for in the present.

Hello; An interesting read. Did find one part of particular interest.

You Asked: Dinosaurs Survived When CO2 Was Extremely High. Why Can’t Humans? - You Asked (columbia.edu)

"How did global temperatures and CO2 levels stabilize before people came along?"

"Extremely high concentrations of carbon dioxide disappear from the atmosphere through three major mechanisms. The first one is that the ocean absorbs large amounts of it to create an equilibrium in the atmosphere."

"Earth’s second mechanism to suck CO2 out of the air is through the weathering of rocks. The products of this type of natural carbon sequestration end up in the oceans as limestone."

"The third mechanism is photosynthesis. Plants absorb carbon dioxide, and if they get buried in sediments before they decompose, the carbon in their tissues gets stored underground. These three mechanisms occur slowly over several thousands of years."

Hello; How weathering of rocks removes carbon from the atmosphere does not add up without further details. Weathering is making smaller bits out of larger bits. Freeze-thaw, erosion by wind and water and such. The rock does not necessarily change structure. Carbon in the rock was already present before the weathering started. More is needed on this.

Limestone is formed in two other ways not mentioned. Likely the greater portion from water creatures which secrete shells or body parts such as clams, oysters, coral and the tiny diatoms to name just a few. Accumulations of the remains can build up in shallow parts of oceans. My take has been this is the way most limestone has been formed.
The other that comes to mind is evaporation in cave formations.

Of course, pretty much all living things are carbon based to one degree or another.

In general, I accept the timeline idea as valid. Too sudden of changes likely do make adaption difficult. Not necessarily impossible.
Many years ago, some Africanized bees (killer bees) were found far south of my location. Speculation was they could not spread to colder areas. Thing is they have been spreading beyond into areas first thought not likely.
Same for fire ants. I knew they were south of Knoxville TN about 15 years ago. Pretty sure I find several nests along a walking trail near my home this past year.
An ideal, perhaps not proven yet, is most types of plants and animals had ancestors who survived extreme climatic conditions in the distant past. As conditions have changed back and then back the other way again the gens kept a record of the adaptations. Not like an individual can necessarily change it's phenotype but a species can. Point being each species does not have to reinvent the evolutionary wheel all over again.
Then there is behavioral adaptation. Humans are perhaps best of all at that game.

Back to a question I posed earlier today.
Quote myself " Next question and perhaps the more important is what benefits can be expected if the agenda of the anti fossil fuel folks is fully put into place right away. I have posed this many times and still wait for responses. I get it is not possible but as an exercise. Say human CO2 goes to zero next week all over the world, when will the benefits of such an action start to take place? Follow up question. If the benefits do eventually take place at what scale will the benefits happen? "

Hello; I know the answers by the way. The literature of the anti-fossil fuels folks has stated many times according to their figuring we are stuck with some warming for a minimum of 50 years even if they get their way. Also, if they get their way at maximum effort the temperature savings will be just a small number of degrees. Go figure???

It wasn’t volcanos that killed off dinosaurs, it was a 15km wide meteor that killed majority instantly then the blocking out of sun light did the rest in.

Hello; Very good point. To be a bit fair I think he is referring to a different mass extinction. There have been a few over time. But you are correct the current popular theory is an asteroid strike in the Yucatan (sp) wiping out the last of the dinosaurs and forming the K/T boundary.
Interesting thing about science. We have to be ready to chuck favored theories at any time. I grew up and was decades old when this latest theory was generally accepted. Thing is even the asteroid strike idea might be overturned with new evidence. Such is the fickle nature of science. Just a tiny fact can trash a beloved notion.

It was the Triassic period as referenced in the article, illustrating the rapid change in atmospheric conditions. Certainly, during the Jurassic period extinction, a giant meteor strike would be considered a rapid change in atmospheric conditions.

Thanks for clearing that up.

So you think that you have done so much reading online that makes you some kind of expert on CC? And people who have differing opinions or simply "uninformed"? That same type of attitude was used with covid. If you don't take everything the media jams down your throat and you question things your a anti this or denier that or some kind of uniformed troll. We have seen how well that all went.

There are plenty of people out there that believe in CC but still understand how EV's are not the answer and may even make things worse.

Because I trust climatologists who are professionally qualified in their field.

I do not profess to be an expert on CC, reading anything on the internet does not make you an expert. The media are not experts.

EV's are just one part of the solution, after all 'EV's' cover many different types of vehicle from PHEV to BEV and FCEV

Hello; Seems you missed the point again. It is the way you for sure and some others treated others during the Covid back and forth. Now you are doing much the same about climate. Not quite so much name calling and overt putdowns currently, but still any of us who dare to differ with you are not qualified to have an opinion and must follow your guide.

You are well known from past experience. Also, that you, as a self-proclaimed medical professional, were so insistent but incorrect about the Covid stuff a lack of credibility attaches.

Wasn't NYC supposed to be underwater by now?

But yea, trust away.

Looks like the V8 isn't going anywhere. GM is developing the 6th gen small block V8.

The Forever Battery That Promises to Change the EV Industry (msn.com)

Hello; the stuff dreams are made of.

Hello; the stuff dreams are made of.

Kinda of reads like the 100 Mpg carburetor.

I'll believe it when they are installed in devices.

Hello; likely can still buy stock in it. Joking in a way. I have no idea if this will fly. Thing is i have seen so many new wonderful things fall flat.

The forth type of person sums it up...

We are still with the early adopters... those who expect a skip to their phase can cry on....

The major problem with any battery tech is you still have to put the juice into the battery. If it stores 100 Kwh's of energy you need to fill it with that amount of energy. To fast charge you need chargers with high frequency welder amounts of power. This is a huge drain on the power grid and very dangerous.
