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.

What ? Climate change is impacting negatively the economy ?

No it's not possible. Remember, 3°C of warming would only reduce the global GDP by 2.1%. (According to Nobel prize winner William Nordhaus)

So please stop complaining, put a hat, pull your bootstrap and go back to the construction site. And try not to fall in the ground because you might get a third degree burn on the asphalt and we can't afford a replacement since nobody want to work anymore.

Imagine how much money shipping companies will make/save when they can send cargo haulers where the ice caps used to be!

The Nordhaus estimates were always known for having limited utility for large changes in temperatures.

They assumed that damage to a sector wouldn't matter much if it was currently a small part of the economy. For example, if agriculture was 2% of the US economy, and agricultural output went to zero, the result would be 2% damage to GDP. The real world doesn't work that way though: people who are starving to death don't work, so GDP would go to zero in that case.
