Maybe it's time to start talking about ways humanity can geo-engineer our way out of this instead of just sitting here waiting to suffer. The US Air Force has been interested in this topic for decades, but there's no way to know how viable any of that research actually is. Some of the speculative documents I've read propose using carbon black dust as a way to artificially reflect heat, like https://web.archive.org/we…

One of the more compelling geoengineering strategies I've seen discussed has been Olivine weathering: https://en.wikipedia.org/wiki/Olivine

From the name I was assuming this was going to be growing olives, turning them into a spreadable butter product, and then burying it underground.

I am from Pakistan and have quite a few cities there were temperature goes up to 50 degrees Celsius. I am living in UK these days and feel that UKs cold will kill me. Summer is the only one or two months when I feel alive.

My mom grew up in Guddu for part of her childhood and her cousins lived down the road in Daharki at same time. I wonder if those get as hot as Sibi/Jacobabad

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.

The Earth has had 2,000+ ppm CO2 concentrations in the past and hasn't turned into Venus. And more or less we're going to dig up all the dinosaurs and plants that died and turned into oil/carbon and put them back in the atmosphere and return to that if we do nothing. But we have a record of what that looks like and its not Venus. That's also a very silly things to "fear" since to turn into Venus you gotta do things l…

The planet has been ice-free in past interglacials, e.g. the last interglacial (before the current Holocene) was warmer than the current. Earth becoming like Venus would take far more terraforming than it would take to turn Mars into a new Earth, probably comparable to turning Venus into an Earth-like planet - i.e. it is not going to happen. In "a few thousand years" [1] the temperature will drop precipitously and we'll be heading for the next ice age if the pattern from the last ~2.5 million years holds. In other words, enjoy the warmth while it lasts, it is sure to get very cold again sometime in the future...

[1] which can mean anything from "soon" to "100.000 years" depending on who does the talking

If it's not ideal right now, how well does it scale if more and more desalination plants come online to meet freshwater demands, and dispose of their brine in the same manner?

The “brine” at the outlet pipe is just 2-3% saltier than the ocean water at the intake pipe. The impact is not zero, but it is very low if done right.

This statement could mean just about anything. My understanding is that desalination plants often have a fairly-sizable fairly-dead-zone around them, taht the salinity is a pretty pronounced local issue.

Sea-water is about 3.5% salt by weight. Are you saying that the brine water coming out is 3.5 * 1.025% salt, or that it's 5.5% salt? Do you have anything you can cite? What % of the water that goes in the inlet makes it to the "brine" outlet?

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...

The turbines do but you can recycle much if not nearly all of that water by cooling the steam and condensing it, which you could use sea water to heat exchange to for it.

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!

How does that compare to the heat I had today? We are 90 at 75% humidity. 60-70% humidity is normal for our summers with 80-90+ weather.

I'm concerned how this article speaks about setting records. Setting new records aren't always a good thing. Setting a new record in climate change destroys uncountable organisms affecting the nature system, and eventually humans. By staying ignorant of our impact on the nature system, we dig our own grave.

> 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.

Yes that's true. I forget about the Dry Side, having never visited there. I'm a transplant to the wet side :)

While the topic is certainly interesting, the way that this article is written feels odd. It reads (to me) like GPT-generated text.

How else would they make you look at all those ads? A lot of the paragraphs were repeating themselves without really saying anything.

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.

Any citation on the portion of American voters who vote for federal politicians who deny climate change? I suspect it’s nowhere near 50%, even if 50% of elected officials deny climate change. Representation is ludicrously disproportionate in the United States federal government.

This is a good point. According to this

https://www.statista.com/statistics/1035521/popular-votes-re...

The Republicans have won the larger percentage of the popular vote once in the last seven elections. Most Americans prefer the non-denialist party but they are denied equal representation at the state and federal levels of government.
