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.

US says climate change threatens wolverines with extinction (www.aljazeera.com)

The tenacious wolverine is under threat as climate change threatens to melt away mountain habitats.

The North American wolverine will receive long-delayed federal protections under a Biden administration proposal released on Wednesday in response to scientists warning that climate change will likely melt away the rare species’ snowy mountain refuges.

Across most of the United States, wolverines were wiped out by the early 1900s from unregulated trapping and poisoning campaigns. About 300 surviving animals in the contiguous US live in fragmented, isolated groups at high elevations.

In the coming decades, warming temperatures are expected to shrink the mountain snowpack wolverines rely on to dig dens where they birth and raise their young.

The decision Wednesday by the US Fish and Wildlife Service follows more than two decades of disputes over the risks of climate change, and threats to the long-term survival of the elusive species.

The animals resemble a small bear and are the world’s largest species of terrestrial weasels. They are sometimes called “mountain devils” for their ability to thrive in harsh alpine environments.

Protections were rejected under former President Donald Trump. A federal judge in 2022 ordered the administration of President Joe Biden to make a final decision this week on whether to seek protections.

It sounds like extirpation is more likely in the short term, than full extinction. Canada has a larger population than the US.
