More than 80 Democrats are calling on the Biden administration to set emissions restrictions on heavy-duty vehicles that are more stringent than what the agency is currently proposing.  In a l…

      US heavy-duty trucks: 417 million metric tons of carbon dioxide equivalent (MtCO₂e) in 2021

      Global shipiping (of which about 40% is shipping fossil fuels around, and most of which doesn’t go to or from the US): ~700 million metric tons of carbon dioxide equivalent (MtCO₂e) in 2021

      So yeah, this is just a bunch of whataboutism and not a meaningful critique.

      Honestly at this point I’m happy to be attacking it anywhere

      What are you talking about? Cargo ships, despite being significant poluters, are far more efficient than trucks.

      It’s necessary to address both sources of pollution, but this is still a big step in the right direction.

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.
