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.

If you’re a US citizen, no matter where in the world, start by making sure you’re registered to vote. Many districts are gerrymandered, so you’ll want to register as the party that’s likely to win congressional and/or state legislative districts where you live, and vote in that party’s primary.

In addition to voting, you’ll want to influence politics beyond that. Your local races are a good place to start; cities and states control local land use and things like building codes.

To affect congress, you’ll want to pick swing house districts or swing senate seats. Volunteer and donate accordingly.

For President, the reality is that Biden has done far more than Trump would even consider, starting with the Inflation Reduction Act, and continuing through numerous executive actions. Getting involved in this race means volunteering, and if you can, donating to the Biden Victory Fund. If you’re giving really large amounts of money, and the logistics of it work, go to an in-person event and talk to the candidate or other official about climate:

The surge is startling scientists, amplifying impacts such as hurricane storm surges.

Across the American South, tides are rising at accelerating rates that are among the most extreme on Earth, constituting a surge that has startled scientists such as Jeff Chanton, professor in the Department of Earth, Ocean and Atmospheric Science at Florida State University.

“It’s pretty shocking,” he said. “You would think it would increase gradually, it would be a gradual thing. But this is like a major shift.”

Worldwide sea levels have climbed since 1900 by some 1.5 millimeters a year, a pace that is unprecedented in at least 3,000 years and generally attributable to melting ice sheets and glaciers and also the expansion of the oceans as their temperatures warm. Since the middle of the 20th century the rate has gained speed, exceeding 3 millimeters a year since 1992.

In the South the pace has quickened further, jumping from about 1.7 millimeters a year at the turn of the 20th century to at least 8.4 millimeters by 2021, according to a 2023 study published in Nature Communications based on tidal gauge records from throughout the region. In Pensacola, a beachy community on the western side of the Florida Panhandle, the rate soared to roughly 11 millimeters a year by the end of 2021.

Scientists say the extreme conditions fueling the fires are the result of climate change. In Brazil, like elsewhere in the world, average temperatures are rising, paving the way for more drought. In parts of the Amazon, the dry season is now a month longer than in the 1970s, research shows.
