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.

I hate leaf blowers. I'd rather use a rake. I can't comment on the landscaping business but when I see neighbors use them I just roll my eyes.

Yeah. Like almost zero impact (zero if exclude the creation process and calories you have to eat) and you are a lot more precise, with the only downside being that it takes a bit longer to finish.

Where I live leaf blowers are really rare. I see them as a very unnecessary luxury.

Leaf blowers seem infuriating to me to use. Where I live people even use them for snow clearing because in the deep cold the snow is light/dry.

I can often go outside, shovel, and be back inside when my snow blower and leaf blower neighbors started before me and are still at it. The driveways and walkways are the same.

I don't know, I just feel like some people love noisy machines and could not care less about anything else?
