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.

Deep sea miners have turned water hoses on Greenpeace activists attempting to block their prospecting in the Pacific Ocean, according to footage released by the NGO.

For the past week, an international team of Greenpeace activists have been using canoes and dinghies to obstruct the Coco, a deep sea mining exploration vessel, as it collects data to file for a mining permit for waters between Mexico and Hawaii.

On Friday, after a Dutch court largely refused an application by miners to stop the protests, sailors on board the Coco appeared to turn hoses on the activists.

Totally agree. Have we already forgotten about things like the deepwater Horizon?

Some of the richest people on the planet are also involved heavily with mining, and that is only because their cost of doing business is the environment and other people's health.

We're trading those things for their profits

Here in Australia in fact, they're running campaigns to try to convince people of how great their renewable gas is (despite only being 5% renewable at the moment, and it's still incredibly inefficient to produce hydrogen compared to battery tech, whilst also wasting fresh water)
