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.

Dubai’s Costly Water World | The city has spent billions of dollars to provide fresh water to its residents and tourist attractions, but experts say the efforts are straining the Persian Gulf (www.nytimes.com)

If no immediate action is taken to counter the harm, desalination, in combination with climate change, will increase the Gulf’s coastal waters temperature by at least five degrees Fahrenheit across more than 50 percent of the area by 2050, according to a 2021 study published in the Marine Pollution Bulletin on ScienceDirect, a site for peer-reviewed papers.

Wait, desalination causes seawater temperatures to rise?

But to maintain its opulence, the city relies on fresh water it doesn’t have. So it turns to the sea, using energy-intensive desalination technologies to help hydrate a rapidly growing metropolis.

All of this comes at a cost. Experts say Dubai’s reliance on desalination is damaging the Persian Gulf, producing a brackish waste known as brine which, along with chemicals used during desalination processing, increases salinity in the Gulf. It also raises coastal water temperatures and harms biodiversity, fisheries and coastal communities.

I was wondering too
