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.

they're illegal on the US interstate system. i don't say this because i think riding from Chicago to NYC on a ebike would be fun or is a good idea but because lots of people use the interstate to go one of two exits from the suburbs into the city.

the interstate system needs a bike lane

Yes, or a nice "green lane" separated from interstate but as efficient.

In Europe we layed out intercity bikelanes on secondary roads, it is very efficient as there are less traffic lights than roads.

Plus, I would prefer not to breathe gas vapors and tires wear during my daily commute, especially with kids to bring to school or activities

In America, we layed out highways to segregate and displace minorities and maximize economic gains related to the consumption of oil.

Riding a bike on I-95 would be miserable due to the noise and wind, but also amazing biking past all the traffic.
