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.

Biden wants network of 500,000 EV chargers. Two states are getting a head start. Ohio and Pennsylvania are leading the way in the completion of a more robust national charging network (wapo.st)

Not everyone just drives a bit and returns home each day.

What percentage don't?

More than 0%, therefore DC fast chargers are needed.

this is true and it's a fact that most people do just drive a bit and return home each day

When it comes to building DC chargers, the relevant question is "does anybody ever drive more than 100 miles from home in this area?"

Even if 99% of your trips are near home, you still need DC chargers for the rest.

Maybe I'm out of the loop! Figured they'd phase it in. Something like:

  • 1 transition fleets - buses, local delivery
  • 2 people commuting in town to and from work on the daily
  • 3 long haul interstate trucking

When the plan is everyone gets 100% coverage, you're absolutely right. We'll need chargers every 50 miles
