Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

For those wondering, one degree celsius increase means every kilogram of air has at least increased by 1°C. The specific heat of air is about 1158 J/(kg*C). Now that might not seem like a lot of energy, in fact 4g (one teaspoon) of sugar has 68,000 J of chemical energy.
The thing is, you might have noticed, there's a lot of air around us. About 5.14 x 10^(18) kg of air. So when you take a pretty normal number and multiply it by an insanely huge number, you get an insanely huge number. That's about 5 exajoules of energy. That is the total energy consumption of the US in 2021 for four million years. Or in sugar terms, equal to the energy of sugar if you converted a little over half of the Earth's entire mass into sugar.
We hit that additional amount of energy in our atmosphere in 2017.
The air increasing by 1⁰C isn't too crazy.
The ocean increasing by 1⁰C is an insane nightmare. Do you know how massive a heat sink the ocean is? For it to change, even by 1⁰, is terrifying.
And we're gleefully adding thermic energy to this constantly at a rate of about four Hiroshima bombs every second.
