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.

‘Megayachts’ are environmentally indefensible. The world must ban them. (www.theguardian.com)

“The rich gazed at their superyachts, and decided they were not enough. The new breed of megayachts, which are at least 70 metres (230ft) in length, may be the most expensive moveable assets ever created.”

“First and foremost, owning a megayacht is the most polluting activity a single person can possibly engage in. Abramovich’s yachts emit more than 22,000 tonnes of carbon every year, which is more than some small countries. Even flying long-haul every day of the year, or air-conditioning a sprawling palace, would not get close to those emissions levels.

The bulk of these emissions happen whether or not a yacht actually travels anywhere. Simply owning one – or indeed building one – is an act of enormous climate vandalism.”

I'm surprised I don't hear more stories about them being targeted by pirates.

Probably not a lot of valuable cargo on board.

The whole thing is valuable cargo

Probably pretty hard to fence a yacht though

[–] AnAngryAlpaca@feddit.de 2 points 10 months ago (1 children)

Probably a lot of very nice and expensive things on a yacht though

[–] Obi@sopuli.xyz 1 points 10 months ago (1 children)

For sure but probably also security personnel, alarms, quick response by law enforcement, etc.
