Climate - truthful information about climate, related activism and politics.

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.

Hell no, the power grid being a central point of failure is enough of a concern, we don't need to lose power to the fridge when any of the other interconnected systems needs repairs.

I have news for you, my natural gas furnace doesn't work when there is no power, either. Turns out you need electricity to ignite the gas, run a fan to exhaust combustion gases, and circulate air through the heat exchanger and ductwork.

Just amazing that the thing I pointed out is true for you too! What are the odds?

But does your fridge being unplugged for repairs impact your furnance running now?

??? the power grid is already a single point of failure. And, with what I proposed a fridge would only have power for the light, it would not need to be plugged in to get cold. You should look into hermetic pump systems before you go off making obtuse dismissals.

What do words mean?

This is why I supplement my heat pump with a wood stove in the winter. In a real pinch I can heat my house with furniture.
