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.

In the US Republican primary debate, moderators ask for a show of hands of how many candidates believe in human-caused climate change. Not a single candidate raises their hand. (twitter.com)

Paper straws and bicycles won't solve the climate crisis. What my lib friends and I are doing doesn't really matter when just a handful of entities make up so much more of the environmental impact.

We could stop those entities...if it weren't for the cons constantly blocking any attempt to help the greater good.

I could tell you how to stop them, but I don't look good in orange

bicycles won't solve the climate crisis

Not with that attitude!

More specifically, not with that disingenuous attitude that implies giving folks bicycles and changing nothing else, trying to shame them into using a mode that's worse for them in order to altruistically help everybody else. Of-fucking-course that's never gonna work!

Instead, what actually has to change is the zoning laws that shape the built environment the bicycles are operate in. We have to stop limiting density and mandating parking requirements, which not only physically force destinations farther apart (putting fewer within walking or biking distance) and cause the space between to be filled with car-infested asphalt (making walking and biking unpleasant), but also subsidize driving by forcing an oversupply of parking, driving down the price.

Removing the regulations and allowing developers to build as compactly as the market would dictate would cause people to freely choose bicycling because it would become more convenient than driving, and that is what would help solve the climate crisis!
