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.

Maybe a world without readily available and affordable coffee will finally make more people care about climate change?

Can't wait for the switch to robusta. ๐Ÿ˜ฑ

Albeit, some work is being done to improve flavor given this possiblity.

I would be sad if Arabica wouldn't exist anymore. But seems to be only a matter of time. Nevertheless, I too have high hopes regarding Robusta. I heard, there is a big potential.

Yeah...you know that's what they said about me...

Me too. All I can do is drink coffee.

robusta has more caffeine and is more tolerant of climates and diseases (robust), arabica has a better taste (original coffee arabs popularized as an alternative to wine).

There's also a very uncool colonial system involved where many small growers are not allowed to sell or export thier coffee crop without jumping through exploitative regulatory hoops that increase the cost at every step. Not to discount the climate impact on the crops. The added cost comes down to greed in both cases - the ones taking advantage of farmers developing countries and marking up the product more and more and the greed of people profitmaxxing regardless of causing and making the climate crisis worse.

it's climate change - it's always climate change
