Yeah, old pickups were gas guzzlers. But pickups as ordinary commuter cars are incredibly rare in the UK.

It's a major problem that they're mostly sold for that purpose in the US.

Old pickup trucks?

My first pickup - 1985 Nissan pickup (manual) averaged 25mpg.

My current 2022 Chevy 1500 company owned work truck gets 19mpg.

Of course the old Nissan weighed 2500 lbs. My Chevy work truck weighs in at 4400lbs.

So fuel efficiency per weight has increased, but the newer trucks larger size still sucks gas.

I still prefer the smaller trucks, so much easier to drive.

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.
