Climate - truthful information about climate, related activism and politics.

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.

Ah, the real reason the boulder Colorado time server is down... Trying to make sure people are late to the protest

/s yes I know this would be nanoseconds at most but it's a joke

I hadn't even considered the massive power outages could shut down power to the time servers. (Giant wind storms on Weds and Fri, NCAR's facility clocked wind up to 112MPH on Friday, in fact. The corporate power company Xcel Energy (that has mis-managed its grid by basically committing deferred maintenance fraud for years in much of CO) shut down most of Boulder and some of the Denver Metro area to prevent Xcel starting another Marshall fire, and they now have to manually inspect hundreds of miles of wires before they turn them back on so some places may not have power for days.)

Looks like the Boulder servers are up but only off by 4.8 microseconds. Probably on backup generators if power hasn't yet been restored. (https://tf.nist.gov/tf-cgi/servers.cgi)

Oh, and I did chuckle at the joke.
