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 did bike commute to a degree with a normal bike but I do so far more often now with the ebike. What's interesting to me is that my fitbit says I'm actually getting more exercise per week now since I ride more consistently, even if the intensity is not as great as it once was.

With the regular bike, I could get so wiped after one day that I'd be too tired/sore to ride the next. And there were other factors that would affect whether I would ride. Is there a stiff headwind today? Is it a heat wave or is the air quality low? Might I have to make a side-trip in the middle of my work day that will wear me out even more?

The ebike changed all that. It also changed the route I take to work. Now I ride through a ravine park I used to avoid because of all the climbing it would entail once I need to leave it. So it's a much more pleasant experience being far from traffic, which encourages me all the more. Honestly, I had no idea how transformative getting an ebike would be?

I could see this. I have a good transit system and at one point had a great pattern of riding in morning and brining my bike on the train on the way back. If I went both ways It was like you said the next day and sometimes even the day after. So the motivation was way down going both ways.
