Anyone have any idea what a 1m and 2m rise in sea level looks like in terms of impact to land that is currently dry but will eventually end up underwater?
Can't we make solar powered ice makers on a huge scale and just re freeze it?
You understand that a refrigerator puts out heat so in the end it’s a zero sum game?
If you're interested in getting involved in addressing climate change, here are two options for citizens to get involved: 1) The Citizens Climate Climate Lobby has been around ten years, and it currently has a bill in Congress that has bipartisan (1 Republican) support: The Energy Innovation and Carbon Dividend Act ( http://energyinnovationact.org/ ). With this plan, all the revenue from a carbon tax* is directly ret…

Is it? That's how France ended up with the yellow vests. It seems likely that demand for fossil fuels will prove rather inelastic, such that everyone just ends up paying more and not changing behavior in a significant enough way.
When is the next US election due? We might need a new administration to get moving on this one. You know... Before we're all fucked.
The cynic in me has wondered the past couple days whether all this new climate change coverage is a full-court press by Democrats in anticipation of the next election. Seems to have become a hot topic in the news just within the past few weeks.
A new generation of progressive candidates are advancing concrete plans to tackle climate change, and candidates talking about their policy proposals should be expected ahead of an election.
Is there a recent swell of coverage? Yes, that's normal. Is this article part of a "full court press?" Sounds to me like correlation but not causation. In fact, I'd say that the Democrats who care, care because they're familiar with the science: the causative relationship is quite the opposite of your cynicism.
EDIT: The title has been updated: it used to say: "Ice sheet contributions to future sea-level rise to exceed 2m by 2100" _________________________________________________________________ Incredibly misleading title. The expected ice sheet contributions to future sea-level rise are, per the article: 26 cm (Assuming CO2 emissions from the Paris agreement) 51 cm (Assuming CO2 emissions in line with current emissions) 6…
I understand. That said, in retrospect, we seem to be well ahead of "X will happen by Year Y" predictions. I guess my point is, better safe than sorry. Because as it is, we're fast-tracking to worst case.
You won't find the answer and that should make the most critical thinkers amongst you to question how much you actually can rely on much of these predictions about the future 30-80 years out.
It seems like that would be a great place to start if you want to convince people that they should spend a lot of money on something that isn't even demonstrated to be a problem we can't handle already now.
What are you ready to do, who's money and freedoms are you ready to spend on being "safe rather than sorry"?
This is the real question we should be asking ourselves.

> Carbon pricing (which can come in the form of a tax or cap and trade) is the single most effective mechanism to address climate change. Is it? That's how France ended up with the yellow vests.

1) In British Columbia, consumption of fuel has actually _gone_ up despite a tax on carbon (now at $35/ton). It had initially gone down when the tax was introduced...
2) The theory of change of the fee and dividend model was that it wouldn't enlarge the state, and therefore it would be attractive to Republicans. I've seen firsthand all the hemming and hawing of Republicans, and I've pretty nearly lost confidence in any of them coming forward--let alone with the conviction and speed we need. It's more likely to me that a liberal majority will strong-arm a green new deal type program in the next decade.
But that's just my take.
Can't we make solar powered ice makers on a huge scale and just re freeze it?
I did a back-of-the-envelope calculation and was surprised how much ice a square meter of solar power can make in a day. But to scale ice making machinery to planetary capacity you'll probably need to use all the metal we've mined, ever. With this kind of massive industrial effort, it's probably cheaper to build big towers and get rid of excess heat by pumping it up and radiating it into space off the night side of t…

Scientists have been ringing the alarm since the 1970s. In the US and Canada, conservatives have gone to great lengths to censor this science and and the center-left has collaborated in the advancement of oil in spite of the increasingly overwhelming evidence that we're causing significant climate change. This study is just some climate scientists doing their jobs, and the publication date was Monday. Such things hap…
Anyway, thanks for the reasoned response.

Thermal energy storage might be able to capture the waste heat. That’s assuming we can make such a massive amount of ice to begin with.
