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.

This is probably why the Australian government won’t release the climate threat report.

Stone cold actuarial analysis predicting devastating results.

It would literally panic the population.

Tropical Asia uninhabitable is not good for the economy. Like at all.

Nor is 60-80 million climate refugees controllable with “tough border policies”

Even just the small part of the disaster that falls under the heading of sea level rise would be just a little bad for trillions in current real estate valuation. And then there's what true risk valuation in river flood plains and wildfire risk zones would do. And then...

Aye.

I read the actual report, well worth looking at.

Very sobering when you see actuaries - the dry math types that make accountants look like party animals state:

.. at what point do we expect 50% GDP destruction – somewhere between 2070 and 2090 depending on how you parameterise the distribution.
