Edit:
Pope Leo X died of malaria in 1521.
Pope Sixtus V died of malaria in 1590.
Giambattista Castana was elected Pope Urban VII in 1590, but died of malaria before his coronation.
In 1623, when the Sacred College of Cardinals was convened to choose a successor to Pope Gregory XV, malaria felled many of these clergymen.

CO2 is not a pollutant. It is an absolute necessity for plant life.
CO2 levels are just barely just above their all time, in the entire history of the planet, low level. If we remove much of it, we will need a new food source because the plants will start dying out. And then the animals. And then, guess who!
Oh, and the oxygen, which the plants make, will run out too! Choke! Gasp!
Somebody needs to actually think this thing out. NOW!

Since biblical times, drought has resulted in migration and conflict.

Ironically, even electronics and computers, generally don't like the heat, either.
Pity we can't just invent something, which can turn heat (temperature) as opposed to temperature differences, into electricity. Saving burning so much fossil fuels and reducing the global temperatures (maybe or maybe not, as that electricity would eventually be turned back into heat, when it is used, typically).
It would be great, if we could all (world wide) band together and invent/construct and pay for massive carbon-dioxide removal techniques, and perhaps then bury the excess CO2, back underground somewhere, out of the way.
Instead governments, seem to go for things like forced LED light ownership and electric vehicles. Yet, they still need enormous amounts of energy and stuff, to be created in the first place.
E.g. An electric car and its batteries, must use up a huge amount of energy and precious materials, in their construction, and will need to get their electricity and spare parts, from somewhere. So are they really saving the planet, like governments, seem to be implying (by their forced introduction, in the coming future, in many countries).

It is simple:
The ones who live on the east side of the city, WORK on the west side.
The ones who live on the west side of the city, WORK on the east side.
The ones who live on the north side of the city, WORK on the south side.
and
The ones who live on the south side of the city, WORK on the north side.
See, it's simple.

That's kind of how physics works though. Heat is a bit like static electricity, unless the heat (or electricity) is flowing somewhere, no work is getting done.

My understanding, is that it might be theoretically possible.
Example:
You use a very high efficiency heat pump, to turn the existing temperature into a temperature difference, perhaps using a fifth (or hopefully higher) of the electrical energy, that would have been needed, to create the heating (temperature increase) using resistive heating elements.
You then use that temperature difference to power a thermopile https://en.wikipedia.org/wiki/Thermoelectric_generator with perhaps an ...

can be used. Then it might be possible, eventually, to make realistic ones, which can 'profitably' extract electricity, out of pure/fixed temperature.
Just that they need to invent, practicable heat-pumps and thermopiles, with the necessary high enough efficiencies, over compatible temperature ranges.
But don't worry. I've heard about and/or spoken to one or more people, who strongly think that the Physics of what I just said, is relatively impossible and it would never work.
Anyway, as a backup solution. Perhaps fusion power will be invented one day (by that I mean our own fusion generators, excluding calling solar cells/panels fusion as they use the suns natural fusion energy system).

That's enough to cause problems but not likely going to be very perceptible to humans or affect the amount of time you'd want to open the windows. Where I live has weather similar to that in the UK and it does seem like our summers are a bit hotter than when I was a kid, but it's always gotten pretty hot for at least a few weeks.

Without getting too deep into the global warming "debate", there's a difference between average climate warming and actual weather. So whilst global warming has only had a sub-degree rise so far compared to 1950, the number of days the UK experiences with weather over 30C has increased considerably as a result.
