Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect!
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

I think climate change is happening far sooner than scientists could have predicted. We focus on increased global average temperatures but I think that we are going to have insanely hot summers sooner. We're fucked.
What makes you think that? The science has been pretty damn good for a long time.
https://www.science.org/content/article/even-50-year-old-climate-models-correctly-predicted-global-warming
Maybe it's more about already being able to see the results of climate change.
Rivers drying out, ice sheets and glaciers melting, oceans heating up, desertification, water shortages, etc.
And with everything it seems like we're "nearly" at a breaking point. Cities running completely out of water, crops failing because of the heat or forests dying or burning, etc.
At least it feels like we're not that far away from a really bad time than anticipated.
You don't need to guess. It was less than 3 months ago where scientists (on nearly every news/publication outlet that wasn't denying climate change) said we are going to blow by the 1.5C estimate we used as a threshold in our models.
Climate change is already happening exponentially now.
Yeah just 20 years ago, much of the world was a bunch of primitive people living in jungles, and the planet could balance the relatively small number of industrialized nations. Today, way more countries have been industrialized. Countries like Vietnam, Thailand, etc are now concrete cities with massive highways and bridges, motorized vehicles everywhere, and factories manufacturing all kinds of stuff and pumping huge clouds of crap into the air. The EU and US try to pass laws and regulations to lower pollution output, but the factories just move to these other countries that have no or less regulations. We aren't at steadily increasing pollution levels, it's exponentially increasing.
The last 20 years saw increased in emissions, but not the the way you claim. see this chart 1990 22 billion t CO2 2003 27.7 billion t CO2 2023 35? 36? Billion t CO2
Even more importantly you can check how the shares of emissions change: Here on this page. 20 years ago the regional emission shares were essentially the same. 30 years ago too. Pretty much only China got really bigger, EU and USA are fairly constant in that time, even tho they moved things like steel production to China.
If I recall they said in that report that we've managed to avoid +4C with our efforts so far, which prevents extinction. But, we've also learned that even modest increases are way more severe than we first thought.
It's a hell of a mixed bag :/
I think the problem is when you show them the projections people would say "you're just being alarmist, clearly you have an agenda"
So the messaging has been consistently toned down in the hopes people would listen.
They've been warning about water scarcity for decades, I think most people accept it's going to be a thing. Tell them this is going to happen in their country, this decade? Most won't believe you.
Doesn't matter that it's already at the breaking point, and that we have still growing populations that are already rationing water from sources that aren't just down due to drought. There's aquifers that would take centuries to fill back up to where they were decades ago
Scientists told us "your grandchildren will be screwed", then "think of the world you're leaving your children"... Well this generation, they're not saying "you're screwed", because people aren't ready to hear that
People don’t want to have to worry or deal with reality so they simply choose to believe otherwise.
Why do you think we still have rampant religion infecting the world.
My guess is its even more than this: deadlines were extended to not let people fall into inaction. The tipping point always close enough so that its dangerous, but still far away enough so that there is still hope. It is a ploy analogous to the fascist "the enemy is strong enough to be dangerous and weak enough to be thoroughly defeated."
This scene is far more realistic, I think. But as you can tell, it doesn't play very well with either the audience or the media.
Imagine being that guy, telling people the same thing scientists have been saying for 100+ years and watching all of them put their hands over their mouths like it's an earth shattering discovery. If only someone had told them repeatedly over the course of multiple generations!
"Who cares?" I feel ya bud.

No, no - it's just as scientists predicted. In the worst-case "no-mitigation" scenario and with attempts from them to explain that +2 global will likely be +10 in peak temperature increase over land (read US, Europe, Asia). As in, both mean and std will increase, but without ocean's mitigation over land.
Fucked is not the correct word - there is a +50 predicted before the end of decade in Strasbourg, where I am from. There is not a single building built there made to resist that kind of temperatures, nor a single tree or crop that could stand that for a day.
And it's a relatively "safe" area as far as long-term projections go...
I would love to read the source on this, not because I think it's bullshit but because that is pretty fucking alarming.
It was predicted, just labeled as "worst case scenario".
Everyone with a vested interest decided to look at the "best case scenario" instead, that predicted decades or centuries of slow heating. Well, nope, "worst case" it is.
