Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Properly vented-to-outside exhaust hoods (not the stupid kind that are built into microwaves and just shoot you in the top of the head with the air) should be required by building codes regardless of range type.

I agree but pretty much all microwaves can have their fan rotated to exhaust external also. It would go a long way to just mandate the required venting to support the orientation.

Exhaust hoods like that are a really bad idea (and actually forbidden in some places) when you have a system which requires open fire like a gas stove, an oven or a gas heating system. They transport air outside and depending on the age of the building not enough fresh air gets in while the fire is consuming all the oxygen.

Also the reason why it is a really bad idea to have a gas heater for warm water and one of the mobile indoor acs. We have some deaths in Vienna every year because of that.

Edit: nevermind, only somewhat true. The slight under pressure caused by exhaust hoods with outside vents pulls down exhaust fumes from the chimney in case of gas heaters. In case of ONLY a gas stove it is not the same problem (I threw them into one basket because most places with a gas stove also have gas heating around here, and in this cases it would be a big no-no).

A mechanical ventilation system with heat recovery should take care of this completely adequately I imagine, if your home happens to be air-tight enough to encounter this problem

In the US, builders have to calculate make up air for this specific reason. In very efficient houses, make up air units need to be installed.

Oh interesting to know how this is handled in different places!
