Yeah, I was looking at this and thinking "At 20m, basically the entire Eastern and Southern Seaboard of the US is gone."

Not at all. Those living along the shore have flood insurance which will continue to pay for restoration of the coastline.

I live in NJ. As I understand it, the state gov - via taxpayers, obviously - subsidizes property insurance at the shore (as NJ calls the beach).

That generosity isn't endless.

These communities are wealthy and influential. Places like Buffalo will go bankrupt keeping places like NYC above water.

The scientists know this. Paleoclimatology is one big part of climatology. But the outcome is the opposite - you should be more scared, since it shows that climate can change massively. That affects things like agriculture or sea level. What would you assume the sea level was, when those plants were alive? For example, with very quick search: "In general, world oceans were about 100 to 200 metres (330 to 660 feet) hi…

> Unless you haven't been paying attention, the most recent IPCC report basically says, "We're fucked, its gonna happen now no matter what."

Yes, the IPCC is finally coming around to using the words irreversible and abrupt in their assessments.

> You can play with the current IPCC model, change where the clouds form, and get an ice age.

I don't recall seeing any mention of a potential pathway to an ice age in any IPCC report or any recent paper from a peer reviewed journal. Are you saying that there is at least one IPCC contributor who will admit that the models are so uncertain that we don't know whether to expect an ice age instead of catastrophic warming?

> weaponize anxiety to encourage action

A reasonable way to encourage action when nothing has been working. People are going even further than attempting to appeal to emotion, they're actually blocking streets and engaging in civil disobedience. That's because people still believe there's hope for themselves and / or their children and they care to attempt to push for the best outcome possible.

> "Being scared" and "being anxious" isn't productive

It absolutely can be. Sometimes you need a good amount of fear or anxiety to kick you in the ass and cause you to act. That's how most of my writing in high school got done as I didn't do anything until the panic set in. It's not ideal, but again...nothing else has been working.

> what I see as fear mongering headlines and articles trying to steer resources to one and only one cause

How many causes are as important as the preservation of habitat for homo sapiens? I don't think very many people share your "No big deal, ... look forward to seeing what the new apex predator looks like" point of view.

Okay. So what do you think will happen when a significant chunk of the United States economic power is under water?

I suspect it will look like Amsterdam, or Venice, or any number of cities that figured out how to cope with existing at or below sea level.

I just went looking for a map to see how different coastlines would look with a 200m sea level rise. It's, unsurprisingly, significant!! https://www.floodmap.net/

It's difficult to imagine the extent and depth of suffering that humans will endure during the transition.

The Netherlands didn't endure much suffering. In fact, quite the opposite.

The highest point in the Netherlands is 322 meters (https://en.wikipedia.org/wiki/Vaalserberg), so even the mighty Dutch might have a problem with a 500m rise in sea level.

I think they're referring to the increasing intensity of severe weather.

I am not a "denier", I can recognize that anthropomorphic activities are changing the climate over time and we're not prepared to deal with that. But this sort of article annoys me because "on record" represents a nanosecond of geologic time. There are mountains, and plant fossils [1] under the ice at Antartica, so at some point in the geologic record there was little to no ice at all! And no humans likely either, wh…

The only solution to fossil-fueled global warming is the elimination of the combustion of fossil fuels. This creates problems for many interests. The United States is currently the world's #1 producer of fossil fuels. A plan to eliminate fossil fuel production within 30 years, i.e. a 3% per year program (meaning, building out that 3% per year as solar/wind/storage) is plausible. However, this would upend the current global economic order. Hence, there is a deliberate effort to not replace fossil fuels with renewables, even though it is now technologically feasible to do so. That's all there is to it really.

No, vast majority of energy is from warm surface waters vs temperatures up into the troposphere.

Once an individual cyclone gets going, that makes it stronger, yes. But what happens to cyclones? They don't just sit in the same place. They move, generally speaking, from the tropics towards the poles. That's what cyclones are doing from the perspective of the climate system as a whole, which is what the post I responded to was talking about: they're transporting energy from the tropics to the poles. (Of course they aren't the only things that do that: the overall circulation of the atmosphere does it all the time. Cyclones are just one piece of that overall picture.)
