Why would it be hyperbolic? What exactly do you think happens when temperatures keep rising to unbearable levels? Keep cranking up the AC? What about the crops that feed the animals we eat to survive? What about the dwindling oceans we farm sea food from?

Dwindling oceans? I thought that the sea levels are rising?

Empty oceans

If Chevron didn’t have customers they wouldnt exist. Like i said, take ownership of your role.

Out of curiosity, how do you suggest that be done? Should I live in a mud hut and eat bugs? Forego interaction with society in a cave somewhere?

If you think I should protest, I do. And, I've pointed out exactly how protestors are dealt with: minimized, attacked, infiltrated, smeared, ignored, and so on.

Every year, hundreds of environmental protectors are murdered. So what exactly is your suggested course of action here?

Keeping adding more temperature reading stations in cities and suburbans and you too will get record-breaking heat trends.

Yes, all of those cities and suburbs in the Indian Ocean, that’s what’s creating the trend described in this article.

It's a very naive view of climate change, on par with "whatever happened to global cooling?" What exactly do you think happens? Runaway greenhouse effect? People just start baking to death in the street? It's senseless. Climate change causes negative effects, but it's much more complicated than that. You should do some reading.

You seem to think life will just continue on much like it is today, with no ill effects or threat of mass extinction. This is denial.

I have the feeling that many people (especially politicians) think that global warming is a linear process. It's not. It might even be exponential since some sources for climate-warming are affected by warmer climate. For example, melting ice that reflects sunlight back to space [ https://arcticwwf.org/places/last-ice-area/ ]. I'm thinking about choosing a new place to live right now. Climate change is a big factor f…

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…

In the field of active climate engineering one can try dispersing aluminum [0] or/and (synthetic) diamond micro-particles [1] in the stratosphere to reflect some of the Sun's light back into space. Especially useful because the effect is temporary and self-healing. An accidental "ice age" will resolve on its own in few months after one stops replenishing the stratosphere with the particles.

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.

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.

One would (likely) have the biggest impact on their own children as opposed to other children, but by volunteering for various organizations one can impact far more kids than the few in one's own family.

No, I don't. I've clearly stated several times that negative effects will happen. You can slap your favorite label on it, not everyone who doesn't immediately agree with your absolutely ridiculous take is a denier and you can't just shame people into nodding their head. I never, not once, said it isn't real. Again, read about climate change and you'll actually know something about it.

Yes. Interesting counterpoint from Scott Alexander: https://astralcodexten.substack.com/p/please-dont-give-up-on...

Thanks for this! Lots of my peers are going on and on about how we're all doomed. I belisve in climate change, and that it's bad and we must act. But I don't think we're gonna be living in Waterworld, which is what my friends are describing.

You should consider the possibility that the climate skeptics are right, also. Imagine how you'd feel if you gave up your chance to have a family, and then one day realized that the scientists weren't being completely honest (as is now widely accepted to have been the case with virology/lab leaks).

Claims about world records in temperature can be extremely confusing. Many times, newly announced "record breaking temperatures" are actually lower than they have been recorded in the past. Here is one recent example:

https://retractionwatch.com/2021/08/16/will-the-real-hottest...

"As anyone who follows the climate news is aware, July 2021 was the hottest month on record for our torrid little orb, according to the National Oceanic and Atmospheric Administration (NOAA), with a combined temperature 1.67 degrees F higher than the 20th century average of 60.4 F. NOAA noted in a Friday press release that the previous record was set in July 2016, and tied in 2019 and 2020. But as Bill Frezza, a sharp-eyed reader of Retraction Watch noticed, the agency’s website tells a different story. This press release, dated Aug. 15, 2019, and still live on noaa.gov, proclaims July 2019 to be the hottest month on record for the planet."

The reason this occurs is that temperatures reported by governments are no longer actual recorded temperatures, but rather the output of models. These models significantly change the historical record, both absolute values and trends, in fact they continuously recalculate old temperature values. Climatology doesn't believe you can answer a question like "what was the temperature at weather station X, Y days in the past" because the answer depends on when you ask it. This isn't really a secret but it's also not well known. NOAA explained it like this:

"NOAAGlobalTempv5 is a reconstructed dataset, meaning that the entire period of record is recalculated each month with new data. Based on those new calculations, the new historical data can bring about updates to previously reported values."

Another example is here:

USA Today Jan 2022 https://www.msn.com/en-us/weather/topstories/the-past-seven-... "Europe sweltered through its hottest summer ever recorded in 2021 and set an all-time temperature record in Sicily of nearly 120 degrees Fahrenheit."

Record = 120 degrees Farenheit.

New York Times 1925 https://www.nytimes.com/1935/06/23/archives/127degree-heat-i... "127 degree heat in Zarazoga, Spain"

So 120 degrees is not an "all time temperature record" and 2021 was not the "hottest summer ever recorded".

Try to remember, claims about the end of the world come and go. Our parents were being told the world would end due to mass starvation when population growth exhausted food supplies, a new ice age (global cooling) and of course the ever-present possibility of nuclear war. Humanity survived and if they'd taken the attitude you're talking about now, you wouldn't exist.

If Chevron didn’t have customers they wouldnt exist. Like i said, take ownership of your role.

And if Chevron (& Exxon, et al) didn’t spend 50 years lobbying, burying evidence, and smearing people who pointed out what they were doing, we wouldn’t be in this situation. I take ownership of my role, and I’ve made substantial lifestyle choices to ameliorate my impac, but don’t act like Chevron is some innocent actor born along by the cruel currents of an uncaring market - they have spent substantial energy and resources making this problem worse in ways not core to their business, and they have done so intentionally and knowingly. They bear more blame than any individual does, both collectively and proportionally.

Don't do that man. The oceans are growing acidic, countless species are being lost forever. We could literally all die because of this. Blaming me for my commercial air travel while Chevron can imprison a lawyer for fighting against them is beyond fallacy, and well past what I can describe in polite terms. Do you have family in the oil biz or something? Why would you do this?

Just because Chevron did something wrong doesn't mean you get off scott-free. Chevron can't fix global warming on their own, it takes everyone, including you.

Actually we CAN go scott free. As per the links, they not only knew about climate change but actively tried to subvert activities related to spreading its awareness. If the general public had the same awareness and sense-of-impending-doom that we have now, do you think these companies wouldve been able to withstand that kind of growing public opposition from all walks of society? Pretty sure they would be forced to course correct.
