The affects of this on third world country are even worse. Here in Algeria we are having the worst drought in over 20 years. What I fear, is that if this continues to happen, people could literally start dying from thirst again. I wonder how good is desalination of sea water technology and if we could see some startups that explore this field, certainly a lot of people's lives to be changed.

I'm not celebrating people dying of thirst, but I also think that's the only thing that will get the world properly focused on the issue. We need to make big structural changes to the global economy to fight climate change, and those changes are going to have an outsized negative impact on today's wealthiest and most powerful people. They aren't going to let change happen without a fight. People dying is what it's go…

Millions of people die from AIDS, malaria, and the lack of potable water and food each year. But most of those deaths happen other continents, so nothing is done about it.

The transmission of HIV could be virtually ended in the US with drugs like PrEP that have been on the market for a decade, halting a 30+ year AIDS pandemic. That didn't happen, and PrEP's price in the US rose from $1200 to $2400 for a 30-day supply in 2019, despite costing ~$40 retail in other first world countries. Now that one formulation recently became generic, it costs $1400 retail, or $600 with coupons, for a 30-day supply. As of 2020 there is a program for those without insurance, but if you're a working adult with insurance, you aren't eligible.

As long as there is money to be made, people dying will be acceptable to those in power.

Earlier quoted context omitted.

Most desalination methods are unfortunately quite energy intensive, and produce a concentrated brine that has environmental/disposal concerns such that it can't just be pumped back into the ocean, really. It presents a difficult problem for entrepreneurs to tackle. Definitely the potential to change people's lives for the better, though.

Stupid question. Can't we just let the brine evaporate and then compress the minerals left over?

In theory sure, but that would consume huge areas of valuable coastal real estate. And we don't really need more salt.

US voters didn't become climate change deniers by chance

How do US voters go about changing climate policy in China and India?

By voting for politicians who contribute and participate in international regulation, like the Paris Agreement, instead of just quitting them.

Trade war perhaps? Against non-nuclear powers (like Brazil), conventional war is not off the table.

How much of that has actually been environmentalists and not a result of intentional deceptive tactics and undermining of public education by fossil fuel companies?

Most of it has been environmentalists.

Can you provide some evidence of that?

It isn't technology that holds back water desalination, it is energy availability/cost. Even the most promising desalination tech is only a small efficiency boost over simpler established methods. Yeah efficiency gains certain help over the long term, but the overall energy costs are still enormous and nearly require dedicated power plant for any significant amount of clean water. The best bet in actually desalinatin…

Wouldn't solar be much better for powering desalination than nuclear power? It is way cheaper per energy produced than nuclear, especially in those countries, which need desalination most. Also, it doesn't take a decade to set up. Not even mentioning proliferation issues.

I wonder if this heat dome effect contributed to Venus' eventual fate. My #1 fear is we're just going to get into some runaway cascade of warming and turn into something like Venus much faster than we realize.

It's kind of sad how we are fantasizing about terraforming Mars, while we've been seemingly very effective at venusforming Terra.

In the US, at least, air conditioning is somewhat common from what I know. It was as hot as +35 in northwest part of Russia last week, for several days, with sun barely coming down at night, and that felt like a torture at times. Some historical records were broken.

> In the US, at least, air conditioning is somewhat common from what I know. Afaik that depends on the specific region in the US. Some states have hot regions where AC is common, but plenty of others don't because heat didn't used to be as common as it's now, thus the sudden need for cooling to such a degree that even public cooling shelters are a thing [0] Another factor, even for places with AC, is that their infra…

Even in hot regions, existing cooling systems may not be designed for higher temperatures happening earlier in the year.

Honestly, why bother? The earth isn't dying, the earth will be fine, it will recover over time, humanity on the other hand needs to be reduced. If it isn't climate change, an epidemic or something else, then it will be war over resources some time in the future. On the other hand, climate change will probably lead to war anyway, since resources like water and places to live will decrease from that, so war is probably…

> humanity on the other hand needs to be reduced The point of view expressed here somewhat ironically show a severe lack of humanity. If anything it seems more humanity is needed here. It’s not uncommon to hear people talk about various types of population control/reduction while being seemingly oblivious to just how tragic and psychopathic the point of view is. If you find yourself agreeing with, say, Thanos, and al…

Population reduction advocates never seem to argue that themselves committing suicide would be the moral choice, which reveals they are valuing the preservation of their own current lifestyle over the lives of the "others".

In practice, it seems like the majority of people who call for population reduction are white/western supremacists who lack empathy for humans born with less privilege.

Birth control should be freely available to every human on the planet. Beyond that, I don't think there is any moral policy available to reduce population.

Maybe it’s time to signal political leaders that climate collapse is an urgent issue.

Amazingly, the GOP just last week formed a Conservative Climate Caucus with something around 60 members. They even explicitly admit climate change is man made
