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.

One way companies like Amazon try to minimize that is by placing their supply chain closer to customers to reduce mileage and improve speed for the customer. Their goal is to make the journey fast and effective, but reduce its emissions at the same time.

“By really leveraging our supply chain efficiencies that we have at scale, we’re able to both offer better speed and sustainability outcomes at the same time,” said Chris Atkins, director of Worldwide Operations Sustainability at Amazon.

Greenwashing. Amazon doesn’t give two shits about emissions, only about costs. You can order 5 items at once with grouped shipping but still have them show up in 4 different deliveries over the subsequent 3 days.

People are more likely to delay or consolidate orders once they understand the environmental impact of fast shipping, according to Sreedevi

That part is true, which is why Amazon offers “lower carbon delivery” as one of its slower options. But it’s primarily emotional manipulation of customers to reduce their timeliness expectations. Reduced emissions just happen to be a side effect that’s convenient to emphasize.

Wow, it's almost like people should start shopping locally again. Ya know, support the little guy, bring our economy closer to us? A little environmentalism wouldn't hurt either.
