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.

In particular, this is a challenge to California's ability to regulate CO2 emissions from vehicles.

"Our findings indicate that the spatial risk of TC-induced damage to OSW turbines along the US Atlantic and Gulf Coast regions is broadly expected to increase, with strong intermodel agreement on the sign of change (i.e., increase or decrease) in all regions assessed. Detailed regional estimates and their associated uncertainties are outlined in Table 1. Significant increases in yielding risk are expected for the Gulf Coast and Florida peninsula resulting from 20- and 50-year storms (Fig. 1), with the average risk of turbine yielding estimated to increase by nearly 40% for a 20-year storm (Fig. 1c) and 27% for a 50-year storm (Fig. 1f). The Atlantic Coast exhibits similar changes, with projected increases in turbine yielding risk of about 35% for 20-year TCs and 31% for 50-year TCs.

Buckling, being a more acute damage state than yielding, requires higher wind speeds to surpass the structural limit. Historically, the probability that 20- or 50-year storms would induce turbine buckling has been below 10% across all regions assessed. However, under future climate change, this probability is estimated to rise to as high as 57% (Table 1), with the strongest increases and future risk expected for the Southeast and Gulf Coast regions (Fig. 2). For the Gulf Coast and Florida, buckling risk from a 20-year storm is projected to increase from nearly 0% to almost 18% (Fig. 2c). This increase is far more severe when considering a 50-year storm, with the buckling risk in this region expected to grow by almost a factor of eight. Along the Atlantic Coast, the likelihood of TC-induced turbine buckling is projected to rise as well, with anticipated increases in risk of about 9% for a 20-year TC and 34% for a 50-year TC. For both turbine yielding and buckling, the likelihood of damage is markedly higher for the Southeast than the Northeast, differing by almost 12% historically and by over 24% in a simulated future climate (Table 1)."

The key thing in there is that the relative cost of electricity and fossil fuels matters enormously when it comes to getting industry to shift. Making electricity cheap is very important.

The pledge was born out of shareholder activism — and was withdrawn as regulators crack down on greenwashing.
