Climate - truthful information about climate, related activism and politics.

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.

The US government is eschewing paper straws and going back to plastic. So why are the plastic variety restricted in many countries around the world in the first place?

Oh common, are we really circling this discussion forever?

We need to reduce burning fossil fuels, everything else is nice, but doesn't really make a dent in the graphs.

You are totally right saying:

We need to reduce burning fossil fuels

Still, we live in a triple planetary crisis, which includes 3 issues:

  • climate crisis
  • biodiversity loss
  • garbage/pollution

Please, do keep in mind that these issues intersect and this is why they need to be tackled in the same time.

I remember my physics teacher - a most rational man - telling us that complaining about burning plastic waste was stupid. Of all the oil extracted from the ground, only a small fraction is turned into plastic. All the rest, the vast majority, is burned as fuel. Burning the rest, too, does not really make a difference. Heck, it could even be better for the environment, as trash incinerator facilities (at least here) have so strong legal requirements for filtering their output that the 90%+ of normal burners like cars, ships, trains, and central heatings just can't compete.

Use paper straws, still wrap them in plastic. Mission failed successfully.
