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.

How surprising - an artificially subsidised industry wants more subsidy

Just to be clear I wasn't being feacious genuinely curious as to the specifics as I'm not as familiar with haulage.

I suspect there is an argument that we've made cargo transport too cheap and its skewed the economics of local vs outsourced production.

My preference would be pantograph systems on the motorways and main routes which we could roll out quite quickly and remove the majority of emissions coupled with a systemic look at our material needs and production capacities locally with a view to lowering volumes

The Silvertown tunnel (and lower thames crossing) in London would be a good example where we are rebuilding our infrastructure along the lines of sustained and increased haulage along certain routes at great public expense so I guess this could be considered an indirect subsidy.
