Salon has no respect from me, so I'm not going to generate a click for them.

Since I'm not too familiar with nuclear - how would the on-demand scalability work? My impression has always been that reactors are generating energy at a fairly constant rate.

[-] NaibofTabr@infosec.pub 6 points 7 months ago

Oh no, the whole point of control rods is to adjust the rate of reaction in the core, which adjusts the rate of neutron output which adjusts the rate of steam production. Newer reactor designs are even more flexible in how the rods can be used.

Huh, the more you know. I always though the rods were only adjusting it at a single percentage point rate, just enough to not let it blow up!

Thanks for the answer!

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.
