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.

I'll note that almost all "carbon credit company" approaches tend to be scams.

President Trump and Republicans in Congress are eliminating federal incentives to buy electric vehicles, but carmakers need to keep selling and investing in them.

The E.P.A. said this week it would revoke its own ability to fight climate change. It’s the latest move in an extraordinary pivot away from science-based protections.

Of the five stations they list in their table, the one which shows the most obvious acceleration (St. Petersburg) is the one they don’t show the graph of! Of course they didn’t find acceleration in U.S. tide gauge records, because they never looked for it. They only looked for what they wanted to see, and that’s all they found. If you do analyze sea level data (and I have), in light of the most recent data (from satellites and from tide gauges) acceleration is obvious, both for the U.S.A. and the globe as a whole.

The Bureau of Land Management implemented four rules today that create more leeway for oil and gas companies wanting to drill on public lands, as required by the spending bill President Donald Trump and Republicans in Congress passed in July. But voters will not have a chance to comment on two of the rules.

Note that they're also making it impossible to locate wind or solar on public land

Cold Nordic countries are being seared by “truly unprecedented” heat, as hot weather strengthened and lengthened by carbon pollution continues to roast northern Europe.

Sorry about the paywall, but the key facts are all in the beginning:

The Interior Department released a new secretarial order Friday saying it may no longer issue any permits to a solar or wind project on federal lands unless the agency believes it will generate as much energy per acre as a coal, gas, or nuclear power plant.

Hypothetically, this could kill off any solar or wind project going through permitting that is sited on federal lands, because these facilities would technically be less energy dense than coal, gas, and nuclear plants. This is irrespective of the potential benefits solar and wind may have for the environment or reducing carbon emissions – none of which are mentioned in the order.

The fundamental problem with a "war" like this is that physics isn't responsive to politics.

Exxon has consistently lobbied against the regulation, due to be phased in from 2027, which will require EU and non-EU companies with significant turnover in the bloc to ensure that their supply chains do not harm the environment or human rights. EU member states will be allowed to impose fines of up to 5 per cent of global turnover on companies found to be in breach of the law.
