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.

Cycling like the Dutch would slash the world’s carbon footprint (www.euronews.com)

Dutch people cycle an average of 2.6 kilometres each per day. If this pattern was replicated worldwide, the study suggests, annual global carbon emissions would drop by 686 million tonnes.

This mammoth figure exceeds the entire carbon footprint of most countries, including the UK, Canada, Saudi Arabia and Australia.

But how much "actual travel" do you do? Most of my travel is urban, where cycling tends to be the fastest and most efficient option when you factor in traffic, parking dilemmas, etc.

I'd say outside of 2-3 months in the winter, I make around 80% of trips by e-bike. The car is still there when I need it. I guess what I'm trying to say is it's not an either/or proposition.

For me, actual travel is 35 miles every day. Uphill elevation change over that distance is 800ft-1500ft depending on the direction.

Most places in the US never considered biking as a valid travel method when being designed.
