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 be taking a bus to a swing state to help elect Harris this coming weekend. You don't need to do quite that much; there are actions hosted near you to join.

The reason is that while Harris isn't in absolute 100% agreement with me on every detail (unless I run for office, no candidate will be), she's the candidate much closer to taking adequate climate action. The Biden/Harris administration did a lot, starting with Harris casting the deciding vote for the Inflation Reduction Act., a key piece of climate legislation. We even saw major cuts to the leasing of federal lands for coal, as well as big cuts to oil and gas leasing

By contrast, Trump appointed a coal lobbyist to run the EPA and took steps to increase not just greenhouse gas emissions, but a wide variety of human-impacting pollutants, and surrounded by people who want to eliminate any effort to address the climate problem

changes in population distribution and land use over the 20th century – including forest fragmentation and the conversion of land for urban development and agriculture – have suppressed wildfires, driving down global burned area by 19%.

However, this decline has been hindered by human-caused warming, which has expanded the area burned by 16% through increasingly hot and dry conditions across much of the world.

Roughly a month after the Ketchikan slide, Hurricane Helene caused hundreds of landslides in southern Appalachia; more than 600 have affected rivers or critical infrastructure. “We can say for certain that we’re seeing more landslides occurring because of the effects of climate change,” said Dave Petley, a landslide expert at the University of Hull in England.

But if CCS operations leak, they can pose significant risks to water resources. That’s because pressurized CO2 stored underground can escape or propel brine trapped in the saline reservoirs typically used for permanent storage. The leaks can lead to heavy metal contamination and potentially lower pH levels, all of which can make drinking water undrinkable. This is what bothers critics of carbon capture who worry that it’s solving one problem by creating another.

In particular, they're looking at charts like this one:

These don't scale down the industry as fast as we need, but do promise a future of sharply reduced profitability.

The $5 trillion industry's move against clean energy and green technology may prove more damaging than political pushback over "woke" capitalism.

You want to keep him from taking office and repeating his pollution-maximization agenda? Then don't just voteget involved as a volunteer for the Harris campaign

IMHO the big thing that will help is actually volunteering for her campaign

Should international climate pacts require militaries to report the amount of greenhouse gases they release into the atmosphere?

He added: “For island states – which make up nearly half of the membership of the Commonwealth – it’s a threat which is truly existential. If we cannot find ways to make our countries more resilient to these shocks, we will not survive.”
