How hot is too hot? Consequences of global warming

Heatwave: How hot is too hot for the human body?

Given the 2023 summer thus far around the world (northern hemisphere), it is a valid question to ask the basic question: How hot is TOO hot? It is a macro question impacting virtually everyone.

Heat, humidity, and the ability to grow food will become driving forces in human AND animal migration in the coming years. We are seeing it in parts of Florida, Texas, and California now (lack of rain/water over an extended period, storms/tides destroying property along the shore, and so on). Expecting people to remain where they can not reasonably survive (i.e., Latin America between Mexico and Colombia) is not realistic as the planet warms even more–and the humidity also rises (making living in many places impossible).

Plan for it. Do not expect to stop desperate people with no chance of survival to be reasonable when they can see they MIGHT make it in the US, Canada, and elsewhere north of Mexico. They do not care what you want. They are “fighting to survive” and they will do ANYTHING they think will help them to survive.

Why not? We would be fighting to survive too.

Not even close to the same extent. We already have the northern areas to move to–just need to make them more habitable as global temps rise, the frozen areas defrost, and people are forced to move further north.

An unfortunate flawed logic just because a person isn’t “comfortable” in the weather and climate. The most lush and populated areas are near the equator. The Earth warming is a natural occurrence that expands on this tropical lushness of ecosystems.

The most lush and populated areas are near the equator.

At temps that allowed people to live there. As the temps go up, the plants change–or die. People can move to other areas to live. Plants can not. Remember: Cacti are dying in the AZ/NM heat, which essentially disproves whatever theory you might be proposing.

We’re just going to ignore the scientific consensus that current warming is twice what could be attributed to natural causes again?

The most lush and populated areas are near the equator.

The greatest population densities are in areas that DO NOT fluctuate to extreme temperatures. And get adequate rainfall.

Here are population density maps by Visual Capitalist.

Zoom in. It’s a fascinating visual. The highest densities are often coastal or moderate or " Mediterranean climate" regions. These are also often “poor/developing nations”.

3D Map: The World’s Largest Population Density Centers

Here is a different visual of the same info, but plotted against latitude.

Mapped: The World’s Population Density by Latitude

Compare the two visualizations.
The latitude map says:
<<Breaking down the population by latitude, we see the population becomes more concentrated near the equator. In particular, the 25th and 26th parallel north are the most densely populated latitude circles. Around 279 million people reside in these latitude lines, which run through large countries like India, Pakistan, Bangladesh, China, the United States, Mexico, and others.>>

That’s NORTH latitude 25 n 26.

25-26° N: the world's most perilously populated parallel

<<the megacities of Asia, which occupy these same latitudes. These include Tokyo (Japan), Shanghai (China), Bangkok (Thailand), Dhaka (Bangladesh), Chennai (India), Karachi (Pakistan), and Tehran (Iran). The population of those seven cities alone adds up to 137 million, w>>

The article has a graphic showing where 25-26 Lat Nth is on Africa.

Comparing that to the other maps, that latitude crosses South FL and south TX, then North MX, and Baja MX.

For reference, Google says: "Hawaii shares the same general latitude of 20°N with cities and environments such as Hong Kong, Mecca, the Sahara Desert, and Mexico City. "

That is because it includes parts of Pakistan, India and Bangladesh. It is not where people live in the United States (not to mention the Saharan desert).

So the major rainforests of Earth like Amazon, Congo, and Madagascar are the least amount of vegetation on Earth? I didn’t know AZ and NM are in the equator band… Not sure why you are straying from my comment.

[Jkenn21]

You are correct that the current warming is happening faster. There is not a consensus to my knowledge that this is a doom and gloom bad thing. We are humans that will adapt in my opinion.
