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.

Importantly, he has backed out of a pledge to reject money from top fossil fuel executives and lobbyists:

Miller said Villaraigosa signed a pledge during his unsuccessful run for governor in 2018 not to accept campaign contributions from oil companies and “named executives” at fossil-fuel entities. She said he took the pledge shortly after accepting the maximum allowable contributions from several oil donors in 2017.

Miller said that more than $100,000 in donations that Villaraigosa has accepted in this gubernatorial cycle were clear violations of the pledge.

Ahead of oil-rich Suriname's election, the country's president tells AFP that a looming energy windfall will not spell a shift away from climate-friendly policies.

The country of 600,000 recently discovered a vast oil field off the Atlantic coast that within years should be capable of producing 220,000 barrels daily.

There will be "a huge amount of income for the country" once drilling gets underway in 2028, Chan Santokhi told AFP in an interview on the eve of the vote. (...)

Note: He got re-elected, which means more oil drilling, there too unfortunately.

It's worth noting that he also fired many of the staff who know how to ensure that they're actually safe, as well as the staff who would approve financing.

For context, increased concentrations of greenhouse gases, including CO2, are responsible for approximately all of the warming that has happened in recent decades:

With carbon dioxide being the largest part of that:

And human burning of fossil fuels (as in power plants) is substantially responsible for that increase:

Based on multiple lines of evidence using interhemispheric gradients of CO2 concentrations, isotopes, and inventory data, it is unequivocal that the growth in CO2 in the atmosphere since 1750 (see Section TS.2.2) is due to the direct emissions from human activities. The combustion of fossil fuels and land-use change for the period 1750–2019 resulted in the release of 700 ±75 PgC (likely range, 1 PgC = 1015 g of carbon) to the atmosphere, of which about 41% ±11% remains in the atmosphere today (high confidence). Of the total anthropogenic CO2 emissions, the combustion of fossil fuels was responsible for about 64% ± 15%, growing to an 86% ±14% contribution over the past 10 years.

  • Agricultural expansion in Brazil’s Pará and Mato Grosso states has destroyed 27 million hectares (67 million acres) of jaguar habitat — an area the size of the U.K. — with 5 million hectares (12 million acres) cleared between 2014 and 2023, most of it illegally.
  • A report by Global Witness links some of this deforestation to indirect suppliers of JBS, the world’s largest meatpacker, which has failed to fully uphold its pledge to eliminate illegal deforestation from its supply chain by 2025.
  • The report highlights weak enforcement of environmental laws and recent attempts by local governments to reverse antideforestation policies, as agribusiness continues to wield major political and economic power.
  • With Brazil hosting the COP30 climate summit later this year, campaigners are urging governments and corporations to fulfill deforestation pledges, improve supply chain traceability, and address agriculture’s growing role in greenhouse gas emissions.
