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.

Bill Gates take on Climate change (fortune.com)

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.

This tech bro needs to go away the same way Elon needs to go away.

I also completely disagree with his perspective on trees because it ignores so much of what we already know that trees do (other than store carbon in their bodies and in the soil around them). Trees are basically straws that take water from the soil and put it in the atmosphere. Along with this they put turpenoids that act as seeds for droplet formation in clouds. They prevent erosion and help infiltration. They increase soil C in both litter and below ground inputs (which extends the duration of moisture into the drought season for most drought limited climate. All of these non-linearties further increase the effectiveness of trees as a stop gap against climate change. Trees buffer local climate and support keeping areas of our planet as functional ecosystems. Without functional ecosystems, we stand 0 chance against this issue. Along with other environmentally appropriate solutions like re-installing deep rooted prairies into the mid-west, tree just make sense.

And most importantly, trees exist right now. They aren't some imaginary technology that emits more CO2 than it consumes because its lab bench level at best. There are species adapted to every climate in every biome on planet earth where it is physiologically possible to grow trees. Trees are something we can do right now that can actually make a dent; they have basically no down-side, and many slight but important upsides.

Bill Gates is a turd that should be ignored in the same manner that Elon musk should be ignored. Just because he enacts his individual will through billionaire "philanthropy" instead of through corporate decision making, doesn't make him some savior to be listened to.
