> And yet ancient Egyptians did it 4 thousands years ago. Have you any evidence of Egypt having those kinds of wet bulb temperatures back then? It's physically impossible to survive high wet bulb temperatures even with an unlimited supply of water without some other form of cooling (i.e. not based on air movement such as fans) as water/sweat evaporation isn't effective. From https://en.wikipedia.org/wiki/Wet-bulb_tem…

Those figures that you quote are not wet bulb temperatures.

https://en.wikipedia.org/wiki/Wet-bulb_temperature

> The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked (water at ambient temperature) cloth (a wet-bulb thermometer) over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature); at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling.

What do you think will happen if the temperatures keep rising, the oceans keep rising, and currently livable areas of land that hold billions of people become inhabitable?

The same thing that's continued to happen: We adapt and create solutions. People have been screaming "everyone will die!!!" via religious based prophecies for... all of human history. The Cult Of Climate Change is no different: a little bit of truth and a lot of faith in Revelations and the unavoidable apocalypse. Prophecies like "all the icecaps will be gone by 2020" and "billions will die from starvation" (hint: th…

The problem with your argument is comparing climate science to religion. There -is- actual science to support the climate doomers. You can cherry pick headlines all you want, but the models have actually been pretty decent so far. Even a little too conservative.

But it's a political problem in the end, anyway, not a science one.

I'm going to guess you've never spent much time outside the bubble of the first world. After living extensively overseas in Latin America & South-east Asia and seeing how its part of everyday life for most people in the rest of the world to openly burn trash, plastics, car tyres.. litter everywhere, cutting the cat converters off their trucks, dumping construction waste straight into rivers.. it's been eye opening. N…

You can wax poetic all you want about anecdotal values differences between the first and third worlds, but speaking in terms of actual practical impact: what you are saying is simply not true. Greenhouse gas emissions scale super-linearly with income: https://www.iea.org/commentaries/the-world-s-top-1-of-emitte... There are dozens and dozens of studies all reaching this same conclusion, if the International Energy Ag…

Yeah and my point is that these studies look at energy consumption they don’t take into account things like burning yard waste or plastic garbage into their co2 consumption which is often done daily to keep mosquitoes away and from laziness. Nor does it look at air pollution nor waterways pollution. So it’s a useless metric that doesn’t even have accurate data or tell the real story.

What will we do when these societies who give no fucks about the environment (compared to the west) get wealthier?

White guilt is not going to save anyone

On the other hand, looking at lived experience the story is quite tricky. From the perspective of an individual it is very hard to detect this level of climate change. I can't tell how much warmer any given month was compared to even 20 years ago. We're talking about 28 vs 28.5°C average for a month. (and July and August made news because of pronounced anomalies, other months were probably even murkier stories due to…

Depends where you live. I live in Vancouver, BC, and the effects here are very, very significant. It used to be that wildfire smoke in the city was super rare, but for the past ~10 years there’s been massive amounts of smoke in the city almost every summer. Weeks each summer where the air is filled with smoke, your throat itches non-stop, and it’s not healthy to be outside for extended periods. Virtually everyone agr…

Global warming is a potential factor, but decades of poor logging practises are also to blame (https://www.sciencedirect.com/science/article/pii/S259006171...).

It's odd how everytime somebody mentions slashing oil production by 50 or 75%, people are immediately up in arms. Same for red meat or cheap air travel. Western rich countries have too many really spoiled consumers. It's weird to say, but we should crash the economy if it can slow down climate change.

I mean there are plenty people in other parts of the world who don't have such a high standard of living, and it's not that big of a problem. The thing is, we have no reason to believe halting climate will do anything other than boost the economy. The reason for inaction despite the fact that it’ll make tons of new jobs, and remo…

Europe has tons of cars and air travel that is cheaper and more plentiful than that of US.

What? Europe has tons of mass transit and walkable cities.

Despite this, they also have a huge length of high speed highways with cars going back and forth. The topology is not much different than in the US. Difference is there, but it's quantitative and will not in any way prevent climate change, especially as it also relies on infrastructure that US does not have and will take a huge carbon footprint to build.

All these comments mentioning cutting down on energy. It will help a bit, but the real problem is there are just to many people on earth. A world wide one-child policy like it used to exist in China [1] would be a real solution in keeping earth a pleasant place to live. [1] https://en.wikipedia.org/wiki/One-child_policy

What % of this warming is due to humans? Aren't we exiting an ice age...?

>people shouldn’t drive a 2-ton vehicle for 40km to buy 200g of Wagyu every other day Your example describes a fantasy. The vast majority of people do not travel anywhere close to 40km to buy groceries. Even in a car-centric country like America, the average driver travels just 4km. If someone has to travel 40km or more to get to a grocery store, it's because they live rural. People who travel that far for groceries…

Here in the UK, if I had to travel 'just 4km' then I wouldn't take a car. In any case it's the other 50% of journeys that are 4km+ (20% of journeys are 10+ miles) that are the problem: https://www.energy.gov/eere/vehicles/articles/fotw-1230-marc... The USA is a young country, built from the ground up around the automobile. Undoing that both physically and psychologically is just not possible in my opinion.

The UK is smaller than Oregon. It's really not an ideal comparison.

Thanos is that you? Wanting to kill people now, to hopefully save the environment in the future.

Why do you think people have to die? Keep the strictly necessary things, get rid of the superfluous. Doesn't seem too difficult to me.

I do, because there is an entire generation steeped in understanding of climate change already taking up policital roles. Minds may be changing (but not fast enough) so intead the politicians changing will be what saves us.
