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.

This article is frustrating for me. Especially his take on trees. The article states the target goal/amount of trees planted would only reduce carbon 6%. Ok, but, it will reduce temperature. I live in WV near a state forest. It is typically 7°-15° F cooler at my house than in town. Additionally, the sun in the summer doesn't even hit my house until noon-ish, which significantly reduces my air conditioner consumption.

I chose to share this mostly for awareness. I am not especially fond of his perspective.

I think the take on trees is massively important when it comes to outdoor planning (or whatever you call it) in cities. Green patches in cities help reduce temperature, making it a safer environment. Oftentimes trees are available in the rich parts of cities but not the poor parts.

Ok but I feel like you and op are conflating local and global temperature. Cities are warmer because of the heat island effect but I'm pretty sure that has basically nothing to do with global climate change.

Local effects are a way to deal with the warming we've already locked in.
