Climate - truthful information about climate, related activism and politics.

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.

You seem to be under several misconceptions:

  1. The force of these polices are applied in exactly the opposite of how you think they are. Zoning reform does not force "stacking people on top of each other;" it allows them the freedom to choose to live more closely together. Single-family exclusionary zoning is, in fact, the policy that curtails freedom the most by forcing everyone to live in only one type of housing whether they like it or not. Any property owner is perfectly free to build a single-family house in an area zoned to allow high density if they want; it's the single-family zoned areas where their property rights are infringed.

  2. Low-density areas are objectively harmful to live in. Physical health is destroyed by the forced imposition of a sedentary lifestyle due to lack of walkability, and mental health is destroyed by the prohibition of convenient access to third places (i.e. forcing them to be miles away instead of interspersed within neighborhoods). To be very clear: this is not an opinion; this is a fact informed by studies showing that people's health and happiness are measurably worse in car-dependent places.

"Allows them freedom"? From my viewpoint, that is straight up newspeak. Which is also a point to be made, our respective frames of reference is so diverse I'm hard pressed to think we would ever use the same language to describe any form of housing. Only in America is walkability a problem in low density areas. Presuming your definition of "low density" isnt rural, of course. And if we are rural, I have a hard time seeing how that can be defined as a sedentary lifestyle. Going for a walk is not usually a problem in those settings, either.
