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.

A new report on the impacts of gas-powered lawn and garden equipment in Massachusetts estimated the devices generated more than 600,000 tons of carbon dioxide in 2020 — an amount equivalent to the pollution from about 135,000 standard cars.

Is it better to get rid of a working gas mower to buy electric? How about a snow blower?

I got rid of all gas power equipment a while ago and have no regrets but I have a small yard and do everything with hand tools (snow, raking, etc) except mowing and string trimming. I use corded, not battery, and while a cord is mildly annoying I never have to charge batteries and the mower and trimmer were both very affordable because of this.

I wasn't sure. Everything metal went to the recycler, most of the rest was plastic or rubber but surprisingly little on a push mower that I couldn't recycle.

Before switching to a fully mulched food forest garden, I used a Fiskars reel mower. For a lawn I'd consider a reel mower first, then an electric, then a scythe. There are free reel mowers on Craigslist from time to time.

How much snow do you get? We get 50 inches (127cm) of snow in winter and a shovel works fine for us.
