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 are correct this is called geoengineering and it is born of the hubris of humans thinking they should control the planet like a machine or something. The person you replied to I believe is appealing to other people who think Promethean action is irresponsible and instead we need to modify our relationship with the environment, by not continuing down the path we are on.

We are already geoengineering whether we like it or not. We just aren't good at it, and we're heating up the climate rapidly. Look at how much carbon dioxide we've put into the atmosphere. We don't have a choice, doing nothing isn't an option, hoping people stop being greedy is not an option.

This is correct, the unknown experiment of removing sulfur from the upper atmosphere causing a more rapid heating of the ocean just ended.

There are talks of the decrease of whales and the loss of their scat, which is high in iron. If they are calculating the amount of iron in the ocean if those animals haven't been slaughtered... We would be kick starting the process

Whaling has caused irreparable harm to ocean ecosystems. We only recently learned that whales contribute largely to carbon sequestration due to what you wrote. Again, people who dismiss iron fertilization as a legitimate solution are a major concern. We need solutions to be implemented NOW.
