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.

It's never been about climate, it's always about the money.

There are a lot of "forests" that are actually stupid monoculture wood farms. So even alleged forest protection can be purely about the money...

Is monoculture the word of the week on Lemmy? Let's be clear, carbon dioxide doesn't care what kind of tree converts it to oxygen.

Monculture only convert about half the Co2 that a real forest would.

How much CO2 does a solar panel convert?

[–] Ooops@kbin.social 3 points 5 months ago

I doesn't need to convert CO2 when it helps to produce less CO2 in the first place.

I don't know. But maybe it should be word of the week, month, year or decade given that the concept seems to not have been stressed enough in education and people constantly miss the issues created by monocultures, wether it's soil damage, higher need for fertilizers, susceptibility to diseases or parasites (reqiring again more chemicals) or the simple fact that plants for monocultures are rarely chosen based on perfect climatic conditions (so even more at risk with changing climate). Ffs... regarding trees in particular the ones planted are often just picked for their straight trunks, so the wood is easier to sell later...
