What is net zero?

I know. CO2 is essential to all life on earth though. Right?

Yes, but too much is detrimental to life on earth.

How much is too much? We could double the CO2 levels we have now and I see no problem with that. Heck, we could triple it and plants will just grow better and give us more food. I don't see a problem. That is still less than 1% CO2.

When life started on earth there was probably no oxygen in the atmosphere. It obviously was not a long term problem.

All life on earth depends on lots of things. Sunlight is required, for example, but too much will kill everything.

Humans don't survive on an earth with a climate like what existed when life began.

I know, but my point is that certain life can survive. We cannot, but CO2 levels right now are very low. The Jurassic had 5 times the CO2 as we have right now. The dinosaurs did fine before the meteor strike.

Too much of anything can be bad. Stop being so dramatic.

C02 traps heat and can radiate it back to earth, warming the climate; too much warming can cause all sorts of issues: annual increases in tornados and hurricanes, deadly flooding, dangerously high temperatures.

Record-breaking heatwaves were endemic throughout the U.S. and Europe last year and the year before. This is all due to climate changed caused by an increase in C02.

Not at less than 1%.

There would be less hurricanes. You are repeating misinformation. You have no evidence.

Scientists disagree.

No they don't. You have been mislead by a false consensus.

So it's no longer warming, it's a 'change'.

Greta Thunberg recently deleted her doomsday post because the date came and went and nothing happened.

"Hmm...this page doesn’t exist. Try searching for something else."

Ooops, it's been found:

Greta Thunberg says: "A top climate scientist is warning that climate change will wipe out all of humanity unless we stop using fossil fuels over the next five years."

Only a few hours ago you didn't even know what "net zero" meant. Yet you believe you're knowledgeable enough on climate change to make that assessment?

Looked him up: not a scientist. In fact, he dropped out of school.

Try again.

Good point it's not the scientists catastrophizing, it's Thunberg, Hayes and you.
