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.

I'm building a new house soon, and looked heavily into this. Live in USDA zone 5 Midwest.

First, like many have mention, I MUST keep gas furnace to handle the few weeks of -10F we have.

SECOND - the cost of gas is SO CHEAP, and electricity SO HIGH - that it ALWAYS costs more to run the heat pump. Even adjusting the heat pump range.

I couldn't justify spending $10k more on the house, just to spend more on monthly bills.

My gas is like $7/mmbtu, and electricity $0.20/kwh.

Given the large number of gas export terminals already approved and under construction, I'm expecting US gas prices to at least double over the next few years, bringing them up to match the international LNG price.

To add to this, I work in Oil and Gas regulation. Unless you're in Texas, prices are gonna go up.

hmm.... maybe i should see just how much money switching to heat pumps is. it'll 10-15 years before they'd need replaced naturally
