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'm really curious about progress made in backpack blowers as they're used decently often for commercial sidewalk snow removal where I'm from.

Ego has an electric backpack blower in their commercial product line.

There are electric alternatives to pretty much any gas engine tools these days. While they often cost more to purchase, they are drastically cheaper to run and maintain. Those high powered two stroke engines aren't only a blight on the environment, they're also unreliable and need a lot of maintenance. An electric motor just works.

All I can say is that I regularly see people using them for work.

(I use a plug-in blower with a 30m long cord)
