Its really depressing to see the extent the polar ice caps have melted

Set this map to 66 million years ago. https://dinosaurpictures.org/ancient-earth#66

You will find that this has happened before, and will happen again.

It starts becoming a lot less scary when you ask, are the people selling me this narrative gaining anything by putting me into an emotional state of panic and alarm, whereby you are always more prone to make impulsive decisions (since there is no hope of future, why bother)?

See where this thinking might lead?

Panic sells papers.

Stop consuming/unwittingly perpetuating propaganda.

It’s also common to say stars are dying.

A star is active and full of energy, while ice is just passive and does nothing.

Large amounts of ice have gravitational potential energy and do substantially more than nothing:

(Encountering crevasses which were not there a few days before is one of the traditional ways for mountaineers to die doing what they love. A local village was recently able to close a nineteenth century missing persons case when the ice disgorged some personal effects.)

For external activity, compare https://en.wikipedia.org/wiki/Glacial_erratic

We also used up all the easy carbon reserves. Not obvious we could bounce back easily if we go to a before the industrial revolution level of technology.

We've also concentrated obscene amounts of hard to extract elements near the surface of the earth.

I only heard about this expedition after it was finished. I would have loved to follow their daily updates, but seems like too much work to go through them here afterwards. Does anyone have a good idea about where news about this type of expeditions are shared up front? I searched to subreddits called something with "expedition" but no luck. So all ideas are welcome. Even more cool would of course be to join an exped…

"Spektrum der Wissenschaft", the German edition of the "Scientific American", covered their expedition regularly. I imagine other pop-sci sites and magazines did too...

I thought if mentioning that. On the other hand, many of those will remain as scrap So I’m less sure how that balances out. The burned carbon is just gone.

And makes the atmosphere less hospitable to boot. So any new civilization with 1800 era tech would have headwinds.

Shame on you: * https://mediabiasfactcheck.com/climate-depot/ > ClimateDepot.com is the website of the Committee for a Constructive Tomorrow (CFACT) employee Marc Morano, a conservative global warming denier who previously served as environmental communications director for a vocal political denier of climate change, Republican Sen. James Inhofe.

I think the parent poster was being sarcastic; either way, you're engaging in an ad hominiem attack. Wouldn't it be better to point out that it is normal for animal populations to fluctuate, or that this is likely a transient phenomenon? Perhaps you could find a study or two to buttress your view? Your comment is more likely to alienate people than to convince them, though perhaps your objective is to improve your st…

There is no point in engaging with outgroups that operate in bad faith.

We are at the point in the climate crisis in which “shame on you” is an appropriate response to climate deniers and bad faith actors.

What confusing maps! Blue ice and white water. There's a clearer map of the actual journey here (along with way more technical info): https://eoportal.org/web/eoportal/satellite-missions/m/mosai...

I'd agree if it were a full color map, but it's a single color map, where the color is used to make the subject (ice) pop. Not to mention artic ice is indeed blue(ish), so the color does accurately represent the subject of the map.

Its mother Nature b we're talking about, no level of optimism can predict what can go wrong.

But humans can currently live in vastly different climates on the earth already. Unless something happens way outside of the worst case climate change models, we’re just not looking at anything near an extinction level event for humans. The big island of Hawaii alone has enough population to not suffer genetic inbreeding problems and it’s mountains mean it can handle multiple meters of sea level rise. The entire rest…

The worst case scenario is the oceans shift to a eutrophic ecosystem https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4802792/

Perhaps we are. But don't do it on HN.
