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

Lower in the article explains why: > Yet despite experiencing large seasonal growth this year, the ozone hole is still decreasing in size overall. "Based on the Montreal Protocol and the decrease of anthropogenic ozone-depleting substances, scientists currently predict that the global ozone layer will reach its normal state again by around 2050," said Claus Zehner, ESA's mission manager for Copernicus Sentinel-5P.

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

The climate over the last 10 years haven't felt or been exceptional. The news has certainly been sensational.

Are you kidding? How many temperature records were broken? How many "once in a 100 years events" happened? Texas had two such winter storms in less than 10 years. There have been record droughts in France, and then record rainfalls. An unprecedented heat dome in the Pacific Northwest. Vast areas in the Middle East and South Asia, and hell the US too, are approaching unliveable wet bulbs temperatures in the summer. If…

Happens all the time. Media wants you to believe otherwise so the rich can get richer and have more control.

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.

Was it? "Two additional regions of Asia were sources of banned ozone-destroying chemicals" https://research.noaa.gov/2022/03/09/two-additional-regions-...

Yes, because despite there being setbacks, the ozone layer is still healing! The hole is getting smaller

Yet I see the “do your own research!” crowd now reference the ozone hole as another example when a cabal of evil scientists came up with a cash grab that the mainstream media terrified everyone with for no reason, and “now no one even talks about it!”.

Yeah, there are a lot of crazies, but there are also a lot of vacation property owners, tennis players, golfers, etc. and saying, truthfully, that no one will be able to do anything outside again, even with sunscreen, nobody will come rent your properties in Florida to go to the beach again, and the solution doesn't cost anything, it should pass.

Which exactly part happens all the time? Each year setting temperature records? "Once in a lifetime" climate disasters? Wildfires getting worse and worse?

On the wet bulb temperature front, it's literally unprecedented and quite impactful. Millions of people would be unable to survive where they currently live and would need to move.

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…

If you are over, say, 25, then you know that the last 10 years have been _exceptional_ years for our climate, and that the time for normal non-sensational warnings was 40 years ago or 50 years ago. Look at a graph of CO2 emissions and you realize that we are in a place where what was alarming in the 80's was the result of only _half_ of the CO2 pumped into the atmosphere since 1900 ( https://ourworldindata.org/co2-em…

> If you are over, say, 25, then you know that the last 10 years have been _exceptional_ years for our climate

And if you know anything about statistics, its that ancedotes are not the plural of data and that humans have a severe recency bias.

The facts about climate change are damning enough, i don't know why people feel the need to resort to poor logic and fallacies when describing climate change. The truth is actually on your side. Lets present that instead.

And yet those same people out right deny that climate change, and its accompanying sea level rise, is a myth. You'd think the wealthy property owners and governor of a state where it's most valuable economic sectors are on the coast and a mere 10 feet or less above sea level would behave more rationally about the preventable danger that has been predicted for decades, but alas.

I guess they're banking on selling their five million dollar beach home to Aquaman.

Couldn't the US also be bigger because of the 10 states most to the east or whatever? Why specifically Alaska?

Alaska is like ~20% of the entire US area. It's the single largest state, which when removed, drops US from >1 million km^2 bigger than Brazil to 500k km^2 smaller than Brazil.

Even Americans don't realize just how freakin' huge Alaska is.

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…

Honestly always fascinated by this kind of line. Like pedantry aside, it always reads like we are all working together towards some big press briefing in the future, to let everyone else know about climate change for the first time. Like who is the audience here? The swing voters here aren't going to decide the election!

Totally agree. The world is the best it has ever been by nearly any metric. My father had to _literally_ practice hiding under his desk at school with a Geiger counter in preparation for nuclear war. He was then _drafted_ into Vietnam... I don't think I have it so bad.

I mean, if we look at history, climate change (even much smaller than what we are facing) tends to trigger wars. Suddenly land that was valuable isn't and vice versa. Even in the most optomistic scenario it will probably destabalize the world order and result in conflicts.

Like e.g. weather events are thought to be one of the likely factors in the late bronze age collapse. There's evidence that unusual climate events coincided with the fall of rome. Like obviously a lot of other factors were at play, climate just pushed something brittle to its breaking point.
