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.

Canada Promises Climate Reparations at COP29 While Courting Big Oil at Home (www.desmog.com)

With spotlight on politicians and their pledges in Baku, fossil fuel lobbyists are racking up private meetings with Trudeau’s government.

In the last year Pathways Alliance, a coalition representing six of the largest oil sands companies, booked 78 meetings with almost 40 senior federal officials including the deputy prime minister, three ministers, three deputy ministers, six assistant deputy ministers, three chiefs of staff, seven members of parliament and two senators. The deputy secretary to the cabinet for clean growth had 38 separate meetings with lobbyists for the Pathways Alliance.

Back at COP29, Canadian hypocrisy is rich indeed. Even if carbon capture of oil sands production worked perfectly, this multi-billion dollar bandaid – largely funded by taxpayers – would only deal with about 20 percent of ultimate emissions. The other 80 percent of downstream emissions from Canadian fossil fuels exported elsewhere in the world now exceeds our entire economy by 327 MT/yr – an amount more than the annual emissions from the UK or 190 other countries.
