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.

So… to summarize the argument: we have to build nuclear plants, even though they are the most expensive renewable per kWh and they take the longest amount of time to build (even by the author’s “fast” timeline standards) because we don’t have batteries that can store wind and solar energy, even though there are multiple emerging potential solutions that could result in days-long storage capacity.

Not buying it. I don’t buy the “unsafe” argument but I also don’t buy this argument

Edit: this same publication that published this op-ed published a pretty negative review of this book, funny enough: https://www.theguardian.com/books/2025/jun/02/going-nuclear-by-tim-gregory-review-a-boosterish-case-for-atomic-energy

“Emerging”- what does that mean? Whats the timeline on them? The failure rate? The cost at the scale needed? I mean if you’re gonna complain about nuclear being more expensive then the batteries need to be cheaper necessarily. Also what materials are they made out of?

I suppose you know don't about the superbattery projects already implemented, e.g. the one in Australia and its huge benefits to their grid?

About sodium based batteries which have become commercially viable in recent years?

And because of the implication also that nuclear reactors produce extreme waste of building materials (e.g. Greifswald, ran for 26 years, dismantling in operation since 35 years and projected to last till 2040 at least, because higher contamination than estimated) and mining for them is at least as bad as for Lithium?

If not ask the search engine/ai of your choice.

This one?

If so it would supply just New South Wales for only 20 minutes. Hardly seems to be on the verge of solving grid scale storage.

Now to the word "emerging"

This was built entirely in 16 months, from groundbreaking to connection to the grid. For the cost of a single nuclear reactor you can build 30 of these. And opposed to nuclear technology batteries are still making remarkable progress in their affordability.

Edit: Btw the battery also uses below 0,5% of the area of a usual nuclear plant.

How often do you think it would need to supply a whole state? Australian states are massive.

I'm in NSW, and from memory, I can think of a few power outages that took down a few tens of thousands of homes for a few days. Most are much smaller. That's in a state with a couple of million homes. So at most a few percent of the state. So even in a worst case scenario maybe you still get a day at full power. If you ration it out to essential services, then a lot longer.

This is all ignoring the fact that most outages are grid related, not generation related, which means that nuclear would be of no help, but a somewhat distributed battery backup system could be massively useful.
