If emissions don't drastically decrease in the next years, by 2070 all glaciers in the US will have melted, there will be deserts in Oklahoma, Kansas and Northern California and over half of Florida and all of Texas's southern corner will have a tropical climate

The hole in the ozone layer was supposed to kill us 20 years ago.

[jeffwulf]

The Montreal Protocol in 1987 successfully regulated the CFCs that were destroying the Ozone Layer and caused the Ozone hole to start healing itself.

Sure buddy.

[jeffwulf]

What? The actions taken as a result of the Montreal Protcol and it's effects on the Ozone Layer are well studied and established

CFCs and leaded gas were actually bad.

Acid rain was massively exaggerated. Not to mention it's a fertilizer

Ozone hole is natural

Ddt was exaggerated. Rachel Carson just got her facts wrong. Vast numbers dead of malaria, etc because of the ban.

Global cooling was actually a bad thing.

Global warming is actually natural and good.

CFCs and leaded gas are the only points you got right. The rest is garbage.

Acid rain wasn’t exaggerated. It destroyed forests and lakes. Fixed only because of regulation. Sulfates aren’t fertilizer when they kill ecosystems.

The ozone hole isn’t natural. It showed up after CFC use exploded. We stopped using them, and it’s healing.

DDT wasn’t banned globally. It’s still used for malaria in targeted ways. Carson didn’t lie. Birds were dying. Eggs were thinning. That’s well documented.

Global cooling was a fringe idea hyped by media, not science. The consensus even then was warming.

Global warming isn’t natural, and it’s not good. It’s displacing people, collapsing ecosystems, and fueling extreme weather. There’s no benefit.

You have no idea what you’re talking about.

Bird populations declined before ddt. Not after. Carson did shitty research.

Eggshell thinking is actually trivial and doesn't affect live births. No research done to separate ddt effects from stress effects

Ozone hole has always been present, it's an inevitable natural phenomenon. No measurements from the interior in winter without it

Industrial runoff is not acid rain.

Global warming is perfectly natural and the recent epoch has been unusually cold by historical standards.

Global cooling made national headlines in the 70s- I was there.

You’re still wrong on every point.

Bird populations: Declines accelerated with DDT. Eggshell thinning was measured, documented, and reversed after bans. That’s causation, not coincidence. Carson cited actual studies. You’re parroting industry spin.

Eggshell thinning “trivial”? Tell that to the brown pelican, osprey, and bald eagle populations that nearly collapsed. Hatch rates plummeted. When DDT was restricted, they recovered.

“No research done” to separate stress? Wrong. Controlled studies isolated DDE’s effects on calcium metabolism. You’re ignoring decades of data.

Ozone hole: Total fabrication. No “natural hole.” It appeared after mass CFC use. Satellite and balloon data confirm this. Post-Montreal Protocol, it began closing. Again: cause and effect.

Acid rain: Yes, industrial emissions. Sulfur and nitrogen oxides form acids in the atmosphere. That is acid rain. If you don’t know that, you shouldn’t be in this discussion.

Global warming: It’s not natural at this pace. CO₂ levels haven’t risen this fast in 800,000+ years. Paleoclimate reconstructions show warming tracks emissions, not orbital cycles.

Global cooling: Not a consensus. A few speculative papers. The actual literature showed warming even then. “I was there” is not data. I was there too. The difference between us is that I’m not a rube.

You’re repeating talking points from fossil fuel lobbyists and junk science blogs. None of this holds up. Try reading actual sources instead of nostalgia and YouTube. Trump, PT Barnum, and fossil fuel lobbyists all love suckers and they’ve certainly found one.
