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.

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…

I have never believed this. The energy cost of operating a modern (or even moderately old) desalination plant is far, far lower than the cost of water in the Bay Area. It’s not even close.

Capital and permitting costs presumably dominate.

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

It's easy to blame political leaders, but they are (mostly) elected by the general population. Here in the US ~50% of the people vote for climate change deniers, so they are the ones you need to convince.

Yes, the solution to climate change has been obvious for a while - hit fossil fuels with increasing taxes until emissions come down to acceptable levels.

Of course, that involves giving up one’s pickup trucks/SUV, international vacations, and 3k sq ft detached single family homes on quarter acre lots.

So…not going to happen. Blaming politicians is a waste of time, it is the people as a collective that have chosen the path.

What about osmotic pumps? https://science.sciencemag.org/content/183/4121/157

Everytime you take your car think about the discomfort you felt by reading the headline.

On the one hand, it is easy to see the direct link. OTOH, you can't blame a person - or company - for playing according to the rules of the game. It comes down to: "Why should I eschew a car and take 250% longer to travel places on COVID infested public transport, when my neighbour Bob jumps in his BMW SUV and drives." We need leadership from lawmakers or nothing meaningful will happen.

A bit off topic, but: COVID should not be a reason we eschew public transportation; we already have enough of a stigma against it in the USA.

I think last year was understandable why some would shy away from it, but if you'll ride in an airplane I don't see why you would be unwilling to take the train.

To some seeing records such as these fall is heartbreaking. It’s agonizing and vexing when you wonder what can you do to help slow down climate change? The reality is we aren’t doing nearly enough to slow it down and the Earth is gradually destabilizing. We see insane cold snaps such as those that impacted Texas this winter, and at the opposite end of the spectrum heat waves unlike anything humans have ever experienc…

As an individual, there isn't really anything you can do. Going vegetarian doesn't help. Recycling doesn't help. Using your shower for 5 minutes doesn't help. As a society, we've chosen to manage resources via capitalism. If you use less water, what that means is water is cheaper so some corporation can afford another few acres of almond trees. If consumers cut their waste in half, the slack would be picked up at the…

Always the violent dictators ready to save us from ourselves… for our own good too.

Never let a good crisis go to waste, heh?!

Solar doesn’t provide nearly as much energy and for desalination you need a surprising amount. Nuclear is a great use-case since the problem with nuclear is it needs a constant water source. If you’re desalinating you’ve got that problem covered.

Does nuclear need fresh water? I'd imagine salt water would wreck all the equipment, and you probably don't want to use up all the fresh water you generate...

You need very pure water for most portions of a nuclear power plan.

Wow, that's Death Valley hot.

I haven't had the opportunity to look up the humidity in BC, but certainly it is far greater than what you would see in death valley. Death valley is a very dry area. The Pacific Northwest is wet and the humidity just adds to the misery of the heat. In my area we saw almost 110° at about 35% humidity. I have experienced 120° in 5% humidity and I have to say the 110 felt hotter! Definitely more miserable!

> The Pacific Northwest is wet

West of the Cascades, yes. Eastern Oregon and Washington are quite dry.

Lytton, BC is in a similar geographic position. It's inland of the coastal range.

It gets 430.6 mm (16.95 in) of annual precipitation, compared to 1,189 mm (46.8 in) for Vancouver.

Check out Frankie MacDonald, he's an autistic savant meteorologist. Not saying that in any disrespectful way, I know some people get a bit butthurt when using those words. I don't know if he's commented on it yet, but if he has, >99% chance he's correct.

> Not saying that in any disrespectful way, I know some people get a bit butthurt… Incongruence detected.

If someone ACTUALLY is a savant with Asperger's or autism, is it disrespectful to point that fact out when you are gauging the importance of their predictions?

I feel like extreme weather is right up there with super moons and other astronomical events when it comes to generating headlines, so I did a time constrained Google search for "heat dome" and here's what turned up: 2020-07-10 - "How a ‘Heat Dome’ Forms—and Why This One Is So Perilous (A massive, intense heat wave is settling over the continental US. The ravages of the Covid pandemic are going to make it all the mor…

We're up to 1.78:1.00 ratio of hot to cold record breaking events in the past year. In the decade of the 1950s that ratio was 1.09:1.00.

US voters didn't become climate change deniers by chance

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

Taking serious steps to make changes in your own country before requesting changes in others.
