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.

Giant Hail Is the Weather Threat Keeping Insurers Up at Night (www.bloomberg.com)

As the climate has warmed, there’s been an increase in the ingredients that make up hail storms: more instability in the atmosphere and stronger updrafts. The altitude in the atmosphere where water freezes has also been rising because of the warmer weather. This means that small hailstones often melt before they hit the ground. The upshot, said Gensini, is the hail that hits will be bigger and storms that produce small stones will be less frequent, thanks to climate change.

Yet even if warming’s effect on hail globally is still emerging, there are clear climate signals in specific places, namely Europe, according to Ian Giammanco, lead research meteorologist and managing director of standards and analytics at the Insurance Institute for Business & Home Safety (IBHS), an industry-funded research group. “The hail across northern Italy, France and that sort of belt is increasing at an anomalously high rate,” he said.

Probably because if you do that, you're on the hook for damage to properties your company didn't underwrite policies for.

Works here, I think all the insurance agencies pay into the program.

But what would you sue them for? The storm was happening and it also doesn’t always work, it mitigates their potential payouts for claims that are already going to happen.

Think golf ball sized instead of baseball, stuff is still getting damaged.
