Personally I would not buy property south of the 45th parallel anymore (in the northern hemisphere). Even north of that we have seen shockingly high temperatures. Anything south of that will become a hellscape within our lifetime.

Cause he’s rich and can afford it regardless what happens. Why would you pay for ice at a convenience store when you could make it yourself at home.

I'd like to remind the HN community, some of whom are rather quick to defend the corporate matrix, that fossil fuel companies saw this coming in the 70s and covered it up.

And they had broad, deep-pocketed support.

Government subsidized them, and protected them after their oil spills.

Media ran Exxon and Chevron's greenwashing ads,

Police beat up protesters, going so far as to infiltrate their groups, seduce their leaders, and have entire fake marriages with them all to keep tabs on them.

Judges sent those protesters to jail - Steven Donziger ought to be a household name, for a recent example.

The military invaded countries illegally for them.

And not a single comment here so far as I can tell is putting any of them on the hook for this ongoing atrocity.

We should start by working to keep the ocean clean, then worry about the temperature of the polluted water. Why is there more interest in controlling the temperature vs the pollution itself? consumerism needs to change for temperature to change

Climate change may very well be an extinction level event. Plastic in the ocean is not.

Reminder that according to the IPCC there is literally no scenario where the human race is worse off in 2100 than we are now, even if we do nothing about climate change and continue to use fossil fuels.

"Extinction event" narratives are not grounded in reality or backed by the science.

Chart has baseline at ~1995. They say we reached 200 zettajoules around 2019. 200 zettajoules => 2.0e23 J * 4.184 J/cal => 8.36e+23 calories They say this is the energy absorbed by top 2000 meters of the oceans. There are 84.8 million sq km of ocean. 2000m * 84.8e6 => 1.69e20 liters of water. 1000 calorie to warm 1L of water by 1 deg C. 1.69e20 L / 8.36e23 cal => warmed by 0.2 deg C since 1995.

Don't you want to divide J by (J/cal) to get cal (as opposed to multiply)?

2.0e23J = 4.78e+22 cal

Let me tell you one thing I've learned: There's never ever a good time to have children.

I imagine raising children is much easier if you can afford round the clock nannies. Or even just retired physically able grandparents a few doors down who can help serve as a redundancy.

My wife and I are those grandparents, and frankly we don’t want the job.

Calgary. It amazes me that despite the Chinese money laundering, the Trudeau Federal government willingness to back residential real estate through monetary, immigration, and legal policies; and just the general Canadian willingness to pretend everyone is well-intended and no one would lie in a mortgage application; that Calgary is the one place in Canada that remains somewhat reasonably priced. Multiple road and rai…

> economy is 50% real estate, That mirrors what Canadians have told me. There's little interest in innovation and building tech when the simplest way to make money is simply housing. The CSeries comes to mind, it was almost ready and had orders for years, then the Trump admin slapped tariffs on it and Trudeau did basically nothing. All it needed was a little capital injection while waiting for the courts to declare t…

Fascinating… I had no idea they grow sour grapes in america :-)

Is anyone on HN reconsidering having children because of climate change? Recently I've had a big shift myself on this topic, probably influenced by not many women my age (younger than 30) having any interest in bringing a child into a world where they could potentially suffer real physical danger due to climate change.

As an European under 30 living in a country whose our society isn't so worried (and we should) about climate change, and I don't personally feel it like a crucial factor in order to have or not a child. Most important factors for us are economic stability and having a couple who also want descendants.

I personally want to have child, and probably would do when I met those two requirement, and probably the most problematic of them are one you also have: Finding a woman who wants that.

Having a child in a modern European country isn't the same as our parents or grandparents had. We have paid parental leave, decent health, nursery, and education services, a society where both parts of the couple can go to work, share home tasks, and care of their childs (independently of being a man or a woman) without having to give up on other things, and so on.

I find it very sad having 40 or more, wanting to have kids, but having conception problems due to your age. I don't if there are statistics about this, and I don't want to influence anyone with this, but from personal experiences, most of the people who decided to not have kids regret that decision, and not too much of those who had them does.

Every year, it seems like we get closer and closer to the end. One day, temperatures will be so hot, and they will not go down. They will only continue to rise, people being kept alive by AC. Then the power grids will fail, and AC won't work, and people will just pass out from heat strokes and die off. And the world will be left with only the few who can withstand the increasing temperatures. And then the temperature will increase even more, and those too will die, or starve from nothing to eat. Bare shelves, dead crops. This is how the end will be. Crime will become rampant as rising temperatures make people more violent and people take what they need to survive by force. Grim.

The irony of this is that the people who care about the wellbeing of the planet enough to question having children due to climate concerns are the ones who really should be having children. They are more likely to raise them to be conscious of issues like this, to look for solutions, and to minimize their impact.

And right there, you have the thesis underlying the plot for Idiocracy, a time-shifted documentary masquerading as a comedy, in which the value of t is claimed to be 500 years, but is actually unknown (and current data suggest far lower value).

I don't want to sound fatalistic but it's difficult to see how we can reset the 4 big feedback loops in any reasonable amount of time: Ice-albedo feedback - https://en.wikipedia.org/wiki/Ice%E2%80%93albedo_feedback Permafrost thaw feedback - https://www.thearcticinstitute.org/global-carbon-budget-perm... Forestfire\Drought feedback - https://weatherology.com/trending/articles/Drought-Feedback-... Jetstream Disruption…

Sulfur dioxide aerosol injection in the stratosphere until carbon capture and decarbonization can catch up. We desperately need an energy inexpensive way to sequester atmospheric carbon underground in stable (mineral) form. Hopefully we’ll see progress from Climeworks or similar concerns in this space. https://iopscience.iop.org/article/10.1088/1748-9326/aae98d/...

As long as so many coal plants are happily smoking and even more are about to be build, I think the first priority is to shut them down and replace those, instead of experimenting with the already quite instable global climate, by injecting more chemicals.

And after we stop emmitting CO2, we can focus on artificial decarbonization. But I would rather invest in proven technology, like reforesting first.
