The indisputable fact that flood maps are going to have to be updated based on climate change makes some people uncomfortable: especially those whose activities are worsening climate change, and those whose income will be greater if they sweep the bad news under the rug.

Well, fuck them. People are entitled to the best information so they can make informed decisions.

C.R.M.L.S. and a few homeowners told The Times they questioned the validity of property-level forecasts, and C.R.M.L.S. said it grew “suspicious” when models showed high flood risk in places that hadn’t flooded in decades.

Who wants to tell them that floods don’t always just target the same places all the time?

@silence7 information to property listings last year disclosing flood, wildfire, heat and air-quality risks, it was following its own research: More than 80 percent of home shoppers consider climate risk in their decisions

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.
