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.

Never mind the planet’s fate when the jet set feel the urge to seek out some winter sun | Self-denial will save the Earth, we’re told. But big emitters seemingly haven’t had the memo (www.theguardian.com)

For the present, research indicates that the public still underestimates, to a degree hugely convenient to the richest groups, their contribution to global warming. The majority of respondents in a four-country study overestimated the carbon footprint of the poorest 50%, and underestimated those of the richest 10% and 1%. One of its authors, Dr Ramit Debnath, commented: “These countries are very different, but we found the rich are pretty similar no matter where you go, and their concerns are different to the rest of society. There’s a huge contrast between billionaires travelling by private jet while the rest of us drink with soggy paper straws: one of those activities has a big impact on an individual carbon footprint, and one doesn’t.”

A whopping 2.5% of global emissions are from air travel.

And I'm fine with it. Solidarity is necessary for a just transition.

But it won't be a significant stop on climate change.

Getting our buildings and cars green will have a much bigger effect.

That's honestly more then I thought and I already felt too guilty about traveling to get on and airplane.

What does the phrase getting green mean to you?

[–] alvvayson@lemmy.dbzer0.com 2 points 1 week ago (1 children)

"Getting green" to me means Greenwashing, lots of talk and ignoring actual solutions.

Solving climate change means getting carbon emissions under control as soon and fast as possible.

Which means a focus on energy use by buildings and road transport, and a willingness to use all economic and technological solutions that accomplish that goal.

What is your plan for steel and concrete? Getting rid of diesel and bunker fuel in transport and mineral extraction? These would be big wins, but there are no easy fixes.
