sounds like we need another term than “normal” state if an ozone layer with a hole is my entire life

Your life is a hell of a lot shorter than the life of the ozone layer, so it's kinda weird to constrain it to that timeframe

The Montreal Protocol has been a massive success and was even strongly supported by Reagan (possibly due to his own skin cancer scare, according to one article). Though I'm highly skeptical it could make it through today's political system in the US.

Nah I think it could pass today. What set it apart was there was an equivalent cost chemical to switch to. It would be kind of like if there were a different liquid hydrocarbon than gasoline that cost the same, doesn't emit CO2, and only took minor tweaks to the engine design to switch to.

It's one of the biggest ozone holes on record — but not necessarily cause for alarm. right nothing to look at here just carry on

If you don't live in the Southern Hemisphere, you'll be fine.

And if you do, I recommend Neutrogena SPF 50+ sports spray.

So if we can survive the next thirty years, we're good. I can barely look forward to the next five. Edit: Woah. Humor doesn't translate well on this site doesn't it? I'm not saying the world is ending. I'm just saying with the next five years it looks bloody bleak, at least for me, turning 40 doesn't look fun. With wars, environmental mess going on; the world looks very dystopian to the vision where it could be utopi…

This sort of ridiculous, silly rhetoric needs to end. It's not just unproductive, it's counter-productive. "ThE wOrLd Is EnDiNg!" is such a tired line, used by religious fanatics since the beginning of time. Modern-day climate activism has indeed become it's own sort of religion, complete with the same sort of doom-and-gloom "repent now before it's too late" rhetoric and increasingly not based on facts or science but…

The people saying we're close to tipping points are scientists, with research papers, not religious nuts.

Yeah but people do this. Consider for a moment that most environmentalism is really just self-preservation... consider the experience of the "earth" over its lifetime, compared to humanities...

Feel the need to *just a thought, Im not some anti-climate change nut job...

Just putting this here for a future "told you so".

It's not "man made climate change", it's the upcoming Sun micronova which will cause a pole shift in 15 to 30 years. It happens every certain number of tens of thousands of years on your planet. You should have felt the sun "feel different" over the last few years. It's getting stronger and it's slowly decreasing your protective magnetic field.

In a few decades you'll be hit with catestrophic floods, tectonic plate movement, earthquakes, and blasted with solar radiation.

So in other words, more clickbait doomer-ism titles. It's disappointing to see this type of junk "journalism" be submitted to, and upvoted on, HN.

i wonder: would clickbait style articles be submitted if there were no karma points?

If you don't know: Brazil is bigger than mainland USA. USA is bigger due to Alaska.

For a more hands-on demonstration, I like this little site which lets you move/rotate [0] and superimpose nation boundaries, while adjusting the shape to account for 2D map projections. https://www.thetruesize.com [0] Rotation of the last-touched country outline is possible by dragging around the "N" compass in the lower-left.

That's really fun and helps put the globes distortion into perspective. Thanks!
