What is global news?

Something that happened or was uncovered recently anywhere in the world. It doesn't have to have global implications. Just has to be informative in some way.


Post guidelines

Title formatPost title should mirror the news source title.
URL formatPost URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefixOpinion (op-ed) articles must use [Opinion] prefix before the title.
Country prefixCountry prefix can be added tothe title with a separator (|, :, etc.) where title is not clear enough from which country the news is coming from.


Rules

1. English onlyTitle and associated content has to be in English.
2. No social media postsAvoid all social media posts. Try searching for a source that has a written article or transcription on the subject.
3. Respectful communicationAll communication has to be respectful of differing opinions, viewpoints, and experiences.
4. InclusivityEveryone is welcome here regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
5. Ad hominem attacksAny kind of personal attacks are expressly forbidden. If you can't argue your position without attacking a person's character, you already lost the argument.

A study in Nature reveals glaciers lost 273 billion metric tons of ice annually since 2000, impacting freshwater resources and sea-level rise.

Assuming constant temperature, would the ice's melting accelerate or decelerate as the total volume of remaining ice reduces?

[–] FooBarrington@lemmy.world 1 points 10 hours ago (1 children)

I think it would decelerate, as there's less surface area.

Not that it matters, since the temperature is affected by the ice going away, so it's an impossible scenario anyways.

Do you think that the average temperature of the ice increases as it melts, decreasing the time it takes for remaining ice to melt?

[–] FooBarrington@lemmy.world 1 points 5 hours ago

Only the average temperature of the parts close to the surface, which is why the surface area is so important.

But by reducing the albedo the air gets warmer, which makes the ice melt faster.

The less ice there is the more heat remaining ice can absorb. It would only be true under constant temperature though.

I was under the impression that with the ice shrinking, the surface area decreases. Therefore the contact area between the ice and the surrounding environment also decreases, slowing down the speed of melting. At the same time though the average temperature of the ice will have increased as it melts so the amount of energy required to melt is less, speeding up melting. I might just have to start measuring the speed at which ice cubes melt lmao.
