Meanwhile in North America, Canada's VIA is operating on a shoestring and being further threatened ... and in the last 50 years the US has pulled up most of the rails that were installed in the previous century. We're stuck with airplanes, hybrid metro-transit, and what's left of Greyhound. But, hey, we've got a world to police!

A second Trump administration would be expected to shred climate polices. California officials are devising ways to insulate its environmental regulations.

As storms, droughts, wildfires and other extreme weather events strike with greater frequency and intensity, repairing and rebuilding has grown more costly, too.

In recent days, Brazilian climate experts have mulled why. Some city council and mayoral candidates are financially supported by activities that profit from deforestation, such as logging and mining, Agência Pública reported. Reporters found that in several areas with high deforestation—and thus wildfires—leading politicians tended to be silent about forest stewardship.

Brazil’s largest political parties generally do not tout climate consciousness as a top issue. The party that appears the closest to doing so is the ruling Workers’ Party. Brazilian President Luiz Inácio Lula da Silva has promoted forest protection and green energy in international forums. But Lula governs in a coalition with centrist and conservative parties and has embraced fossil fuel exploration domestically.

To Angelo, a former science editor at Brazil’s newspaper of record, Folha de S. Paulo, climate was discussed so little in the campaign in part because “mainstream media tries to replicate the conversations that are happening on social media,” rather than journalists trying to orient the news cycle around policy questions.

The imaging spectrometer aboard the Carbon Mapper Coalition’s Tanager-1 satellite identified methane and carbon dioxide plumes in the United States and internationally.

Using data from an instrument designed by NASA’s Jet Propulsion Laboratory in Southern California, the nonprofit Carbon Mapper has released the first methane and carbon dioxide detections from the Tanager-1 satellite. The detections highlight methane plumes in Pakistan and Texas, as well as a carbon dioxide plume in South Africa.

The data contributes to Carbon Mapper’s goal to identify and measure greenhouse gas point-source emissions on a global scale and make that information accessible and actionable.

"Even temporarily exceeding 1.5 degrees Celsius before bringing temperatures back down — a scenario known as an “overshoot” — could cause sea level rises and other disastrous repercussions that might last millenia."

This has been one of the inherent problems with any kind of carbon removal — there's no real way to profit from it, so it was unlikely to happen at scale bigger than a PR operation unless government either pays for it or requires firms to pay for it.

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.
