Australia now has so many residential solar installations that it's meeting close to 100% of demand at times. This causes problems with stability of the grid as traditional sources such as coal and diesel cannot operate below a certain minimum. The grid operator is asking for the power to throttle small scale solar in cases of emergency.

Storage of energy will always be the real challenge. Generating it always looks so sexy and innovative but the age old Achilles heel will be an effective means of storing it

That only got him the weird looking Biily Eyelash sucking his nuts.

Not good enough

Seminar I did on Strategic Minerals was mainly about batteries. Most of the talks were about existing tech, mainly lithium given by folks heavily invested in lithium resources but one guy gave a very conflicting talk that fired up the crowd. Simple economics, as the price of lithium goes through the roof, R&D will come up with a different technology that does not use lithium. It was such a simple argument that there was nearly an audible "oh fuck" heard through the Zoom seminar.

The other very cool talk came from a US State Dept rep on the geopolitics of securing reserves. We are fucked. China is miles ahead of the west. Biden's $1B aid to Africa yesterday was was all about securing strategic minerals.

Oh, and China just cut off the US from their exports.

When rebuilding the fire ravaged sections of LA they should look at Brasil. Brasil puts the barios on the hillsides for the natural disasters to cause havoc with.

I wonder what the deforestation protests and carbon tax were at the time.

Wait a minute.....

You're saying that the world was warmer than it is now only 5000-6000 years ago?

And that plant-life wasn't wiped out?

No, it is much warmer now. This is the warmest it’s been for at least 130,000 years, or roughly as long as there have been homo sapiens.

But! When the last ice age ended, about 12,000 years ago, give or take, it got warmer and it kept getting warmer for quite some time. Then about 6,000 years ago it started getting colder, and then at some point after that this 6,000 years old forest got covered in ice. Then about 300 years ago we had the industrial revolution and started burning coal, and since then the temperature’s been rising at an accelerating speed. And in only a few centuries we have managed to thaw all the ice that formed over millennia.

Here’s a chart, it’s more than 10 years old though. In 2024 we hit 1.5 degrees over that average they’re using as 0, so way way hotter than the neolithic climate. But it still gives you the general idea.

If we go further back it has been warmer though. It was way warmer back when dinosaurs roamed the earth, but that climate would not have been suitable for humans.

Well done, Per. Very interesting, yet very concerning.

Btw, when you look at that graph you also see why scientists in the 19th and early 20th century suggested we were heading toward a new ica age. But then carbon emissions changed the course of events.

Oh yes, it's all because of human activity lol...

Well, mostly.

I mean, we've changed the composition of the atmosphere rather dramatically. That change is completely on us.

We've been through this extensively in the past.

I maintain CO2 is not a greenhouse gas.

That’s interesting. So all the scientists, from the 19th century onward, have been wrong.
Have you told them yet?

And if so, why is it getting warmer when we really should be trending toward a new ice age?
