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 love my electric mower, but the batteries are awful: too small for a motor that sized. The high current draw + summer heat absolutely destroyed the batteries after a season. The 5 Ah replacement batteries are like $150 (they also fit my weedeater, leaf blower, and hedge trimmer).

Ended up hacking a 10 Ah e-bike battery onto it (plenty of room inside the housing) and wiring just the board from the old factory battery to trick the DRM or whatever on the motor controller into letting the mower work. Drilled a small hole for the charge port, and it's been a dream.

The small-battery problem is really a pity. I don't have enough lawn to end up using anything other than a reel mower, which doesn't have the battery problem.

My yard is too big for a reel mower but too small to justify maintaining a gas mower.

After the battery hack, the electric one has been great. I just wish it'd have been designed like that from the start.

I had a corded one before this, and it was more trouble than it was worth wrangling the extension cord around, not running over it, and just dealing with it in general.

I'm supposed to be maintaining this?
