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.

I remember an urban planner and climate scientist/communicator discussing the changes that need to be made. He pointed out in his research and the book he published based on it, that it's cheaper for governments to do climate friendly change than it is to maintain the status quo regardless of climate disasters. He says that yea it's degrowth, but it needs to be framed as efficiency to get interest

Do you remember the name of the book?

[–] rockSlayer@lemmy.world 5 points 5 months ago

It was called Project Drawdown. The statements about degrowth are just author comments about the research, and didn't get discussed in the study

Just one thing I believe to be really important in selling it:

less consumption -> less production -> less work

That means degrowth is earlier pensions, shorter work weeks, more vacation time and so forth. For many people chilling on the beach is saving the planet.

Good thing we didn't spend the last 50 years attaching everything to the stock market because that would have been a real pain to untangle

Yeah, everything is expressed in monetary value. But health, clean air, clean water, health nature do not have monetary value, so they don't matter.

GDP is the total of wealth generated. So a housing shortage, pushes up housing prices, which looks good on the books.. look at all that economic growth.

I was going to comment "Solarpunk", and then I noticed the instance. heh

A word of caution: there is not a constant relationship between carbon emissions (or energy use, for that matter) and GDP. Some economies are far more efficient than others. Some of the most efficient countries are among the wealthiest. So at very least, it is not inevitable that improvements in energy efficiency will mean reductions in GDP, and it certainly doesn't make sense to assume that a reduction in growth will lead to a corresponding reduction in energy use or greenhouse gas emissions.
