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.

Findings suggest that prior to shifting beliefs, participants were similarly skeptical or rejecting of climate change, while remaining diverse in the ideologies that influenced these beliefs. For most participants, shifting beliefs were catalyzed by three key experiences:

  1. distancing from ideological community
  2. desire to seek out information, and
  3. solidifying experiences of gradual or epiphanic realization

As the atmosphere continues to fill with greenhouse gases from human activities, many proposals have surfaced to "geoengineer" climate-saving solutions, that is, alter the atmosphere at a global scale to either reduce the concentrations of carbon or mute its warming effect.

"Our work showed that the efficiency of the proposed technology was quite low, meaning widespread adoption of the technology would be required to make any meaningful impact on atmospheric CH4," said Mayhew, a postdoctoral researcher with the U's Wilkes Center for Climate Science & Policy. "Then, our results indicate that if this technology is adopted at scale, then we start to see some negative air-quality side effects, particularly for wintertime particulate matter air pollution."

For some time, there has been a forecast that The Great Salt Lake, once one of the largest inland salt lakes in the world. New data confirms the likelihood of the disaster.

If the lake does disappear, it causes real problems. According to NPR, “The big unknown is how bad dust storms could get from a dried up lake bed. There is precedent. Along California’s Eastern Sierra Nevada mountains, years of water diversions from the Owens River by the city of Los Angeles caused downstream saline Owens Lake to dry up. Dust storms from that lake bed became the largest single source of dust pollution in the nation.”

A report by risk experts says previous assessments ignored severe effects of climate crisis.
