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.

Wheat production is down 15% since November, the biggest reduction in cropped areas since 2020. Oilseed rape is down 28%, the biggest reduction since the 1980s, and winter barley is down 22% at 355,000 hectares, the biggest reduction since 2020.

So, the above effects, every 3 years.

And we're just getting started.

Not to stray too close to giving denialists ammo, but wasn’t putin’s war a massive disaster for crops? Ukraine being bombed to a bloody pulp is likely at least partially to blame for these numbers I assume

How did the war in Ukraine affect UK crops?

Ah fair, missed that the original article was limited to the uk

What are you on about? No, if you read the article you can see this is about food grown in the UK, meaning the United Kingdom. This has nothing to do with Ukraine.
