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 for a Democrat and donate accordingly.

For President, the reality is that the Biden/Harris administration has done far more than Trump would even consider, starting with the Inflation Reduction Act, for which Harris cast the tiebreaking vote in the Senate, and continuing through numerous executive actions. Getting involved in this race means volunteering, and if you can, donating to the Harris 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:

Climate activists disrupted a DNC-adjacent event sponsored by ExxonMobil on Wednesday, the same day that Minnesota Governor Tim Walz formally accepted his nomination as vice-presidential candidate for the Democratic Party. Walz has faced harsh criticism from Indigenous and environmental rights groups in Minnesota for his authorization of the Line 3 oil pipeline through Native treaty lands in the state. We host a roundtable discussion on the climate crisis and the Democratic Party’s response with Ojibwe lawyer and founder of the Giniw Collective Tara Houska; climate organizer Collin Rees, who was part of the ExxonMobil action at the DNC; and climate scientist Michael Mann.

"There are thousands of glaciers and glacial lakes in the Himalayas – but very few in the Everest region are monitored and have early flood warning systems installed.

Meanwhile, global warming is accelerating the melting of glaciers which can fill up the lakes to bursting point.

A 2021 study led by the University of Leeds found that Himalayan glaciers have lost ice ten times more quickly over the last few decades than the average rate measured since their expansion 400 to 700 years ago.

Another study published in the Nature journal in 2022 found that Mount Everest’s South Col Glacier may have lost half its mass since the 1990s as a result of warming..."

"In recent years, Europe has experienced some of its hottest summers, which have coincided with high mortality rates. Elderly people are at heightened risk of death from extreme temperatures, and the number of people reaching old age is projected to increase over time.

Most previous studies projecting deaths from hot and cold temperatures in Europe have contained little local-level detail or have been in-depth assessments for individual countries, mostly in Western Europe. This study is the first in-depth analysis of the current and future health risks from hot and cold temperatures across Europe to look at the predicted impact on regions within countries..."
