Yes they have. Wrong every year. I see you still use the internet. Co2 use is high for you.

Stop trolling

You are wrong about what I believe is true. I’m wrong about what you believe is true. There, problem solved and nothing left to argue about.

 

i'm going to borrow this comment. fantastic.

At low altitudes water H₂O (vapour) is by far the biggest GH gas threat and at those levels the H₂O molecules considerably outnumber CO₂ molecules. However, as we all know,  H₂O readily condenses forming clouds and rain but CO₂ does not. Earth's gravity prevents CO₂ escaping into space and so the 'blanket' gets thicker but it's the lower layer of CO₂ that absorbs most of the energy. The higher layers simply keep the energy for longer and that is the problem. The current CO₂ level is about 0.04% (trivia-Venus is the hottest planet in the SS but its atmosphere is around 99% CO₂ ) CH₄, N₂O and O₃ are GH gasses to a lesser extent. As well as agricultural products humans and other animals (cattle for example) produce CH₄.

Wind Farms, Solar Panel areas aren't supplying and cannot supply right now, the demand for electricity and fusion reactors, it seems, won't be near supplying the grid anytime soon.

So we've gotten ourselves into a bit of a rut. Well, what can we do? We could ALL stop using our combustion vehicles, stop using aircraft for holiday trips, stop using...That is just not going to happen! We have to face that our 'needs' have outrun progress in technology-for example the weight of the batteries in EV's is roughly 40% (give or take a little) of the total. The batteries will become smaller as research continues but it isn't going to happen overnight.

The dinosaurs were eating their way to being doomed, the asteroid/comet strike just made it sooner...is it now our turn? I think we are intelligent enough to avoid it.

Of course it might be just one big conspiracy to make us all bow down...everyone has to decide for themselves.

 

Wishful thinking. Humans will never give up their creature comforts even if it destroys the planet. The governments will never allow alternative means of producing the electric demands as long as they profit from oil. Even this push for EV will find more opposition than acceptance but still will need coal and oil to sustain the demands for electric. For those who think all this is propaganda for global warming they simply need to look at temperatures, basic sea life patterns, and the ice caps to know it is real. They are the ones who will slow the process to heal the planet.

I was just trying to give a 'balanced very brief' intro to calculating problems. Unfortunately, I agree with you and my personal opinion is that we have already passed the point of no return for one reason or another. We got ourselves into this mess and the alternatives for even part correction are not acceptable. Fusion energy is still a long way off so we can discount that as a solution. Pity.

Good news. Once humans exterminate ourselves the Earth will soon return to a natural state. In a “blink of an eye” of geologic time .
