Apparently, it IS under control now, but damn, what a crazy sight.
I saw that. And one of those things I felt I had to check multiple tips for being real. It was.

Who had “fire from hell burning the ocean” on their bingo card? I mean damn.

BTW, while I’m sure appropriate and they are the experts, I found it odd to be dumping water on a fire, in the water.

how about twice in 1 month


*the "mud volcano" part apparently came from the State Oil Company, so yeah .. they're believable when something like this happens

Water shortage in the West. As bad as it is now, it could get worse next year, The overall water system is at 40% of capacity now and is expected to keep dropping. Replenishment from snowmelt normally doesn't happen until March, and there is no guarantee how much we will get.

The West Coast megadrought and its impact on water supply to AZ, NV and CA. This is a long term problem and it won't be fixed even with a few years of heavy rain and snow.

I liked that woman from the southern Nevada water district. She pulled no punches.

She's been giving interviews on water depletion for a while but few have been paying attention until this year. The "bathtub ring" pictures give a dramatic visualization of the problem. As bad as things are already, they are worse because we are masking part of them by digging deeper and deeper wells and pumping out water from aquifers. I read that in some places the land is subsiding by 1 foot per year.

That seems like the story on climate change. Deny. ignore and hide it until it's late.

Hydropower plant at Lake Oroville, CA, had to shut down due to low water. We are far from the lowest water point of this season, so this will be a long and tough summer. Other hydropower plants have a similar risk of reduced output, but I think this is the first major one that has to shut down entirely.

I didn't know that Siberia is having the worst forest fire year ever.

Besides the CO2 generated by those fires, there is also risk of release of methane which is much worse (25x?) than CO2 for global warming.

Small steps for a promising technology.



https://www.reuters.com/business/env...nd-2021-09-08/
COPENHAGEN, Sept 8 (Reuters) - The world's largest plant that sucks carbon dioxide directly from the air and deposits it underground is due to start operating on Wednesday, the company behind the nascent green technology said.

Swiss start-up Climeworks AG, which specialises in capturing carbon dioxide directly from the air, has partnered with Icelandic carbon storage firm Carbfix to develop a plant that sucks out up to 4,000 tons of CO2 per year.

That's the equivalent of the annual emissions from about 790 cars. Last year, global CO2-emissions totalled 31.5 billion tonnes, according to the International Energy Agency.

A different way to look at California fires, by burned area. 2020 and 2021 (with 4 months to go) are already more than half of the damage of the last 100 years.

Perhaps the suppression of fires between 1932 and 1999 had something to do with the large fires from 2000 onward?

Re: The One and Only Global Warming Thread, Part 11 (CO2 Kills 10 Billion People Edition)

The idea behind a fire is that we need combustible material and a spark, and right now we have a lot of both. There was a recent New York Times article that talked about it: https://www.nytimes.com/article/why-...wildfires.html

They listed 4 big factors:
- The changing climate: Higher temperature, lower humidity
- People: They live closer to forests and cause sparks. Power lines also.
- Fire suppression: We have let a lot of combustible material accumulate. It's also harder to do controlled burns because of people living around.
- Santa Ana winds: CA has a second fire season from October to April driven by these winds. We have not seen them this year yet and they will add to the 2021 total.

One issue with carbon capture is why would a company do it? How do they make money? I’m guess this example has government backing, which means talking tax payers into it.

But from the article,“U.S. oil firm Occidental is currently developing the largest direct-air-capture facility, to pull 1 million tonnes per year of carbon dioxide from the open air near some of its Texas oilfields.”

Soooooil companies might do it so they can continue to drill! Yea!?!?

I realize we are at the beginning of an emerging technology/industry. And I think I saw some small scale efforts to use carbon capture as bricks and/or to make concrete. Which is the most common construction material. So there could be profits there.

Don’t get me wrong, totally for it. And instead of oil companies doing it, make them pay a carbon tax (yea I said it) so others (maybe non-profits) build and manage these carbon capture units

Yes, "carbon tax." That sounds terrible and weird, but we already have similar things. Many companies do very costly things for air and water pollution abatement, and people pay for catalytic converters in their vehicles. Those things have no direct benefit to them, but they are required and seem quite normal and accepted now.

Many companies such as Microsoft and Google have adopted a goal to be carbon neutral in 10-15 years, and part of their plans is to pay for forests that would otherwise be clear-cut mainly for agriculture (which would contribute to warming gas increase). They can do that through a carbon "tax" or a carbon credit "bank" that charges them for the carbon gas they emit and gives them credit for what they remove.

With all the consequences of climate change, we are already paying a huge price or tax, but it's less direct and obvious to a lot of people. We need to fundamentally change the way we think about and preserve our Earth.

I'm a little suspicious of that carbon capture plant. Would it even be carbon-negative if it weren't powered by the basically free geothermal energy that's available in Iceland?

For now, the Icelandic installation, which is called Orca — phonetically the same as the Icelandic word for “energy” — is an unlikely global savior. Human-sized fans are built into a series of boxes that are the size of standard 40-foot shipping containers. They sip carbon dioxide out of the air, catching it in spongelike filters. The filters are blasted with heat, about the same temperature needed to boil water, freeing the gas. Then it is mixed with water and pumped deep into underground basalt caverns, where over time it cools down and turns into dark-gray stone.

Yes. Subsidize it. Structured with a carbon tax. We should do the same with recycled materials that are currently unprofitable to recycle. Reduce those taxes on uniformly manufactured (simple to recycle) single use products.

When government starts paying recyclers per ton, we will see landfill materials virtually disappear, which will shift the supply chain for raw materials.

We could go further and fund cleanup projects to fix the damage already done.

Probably not. From what I've seen -- lots of moving parts on heavy machinery that use heat -- that thing likely has large energy requirements to operate, so unless they have something that doesn't rely on burning fossil fuels to run it on -- solar, geothermal, or hydro -- it's probably going to either have negligible effect (and it's already pretty negligible; it supposedly removes the equivalent of the output of 800 cars or something), or actually release more carbon than it removes.

Since this is the first commercial-scale carbon capture plant, they want to make it as green as possible partly for symbolic value. Use renewable energy to run it, and store the carbon captured in natural rock formations (instead of empty oil wells as has been suggested).

Two key metrics are:
- 90% energy efficiency. For every amount of carbon they capture, they use the equivalent of 10% to build, operate and eventually dismantle the plant. If they use non-reusable energy, that will go up to less than 20%. The entire process includes flowing air through carbon-capture filters, and releasing carbon from the filters by heating them to 100C. Not a big energy-intensive process compared to many other chemical plants.
- Capture efficiency, For its footprint this plant is 1000 times more efficient at removing CO2 from the air than trees.

This is the first plant of its kind, and there is more optimization to be done when they scale up and build more plants. I hope they we have thousands more like it.

I hope it works too. But we would need a million of them to match what humans put into the air each year.

carbon capture shouldn't be the only thing we do to fight climate change, but without it we have no chance to keep warming under 1.5 deg., which is the goal most people agree on.

What's good about it is that it's relatively easy and fast to scale up. Simplistically we can look at how big a gap we have to our goal, then decide how many plants to build. Cost is an issue but otherwise the solution is ready. If there is an absolute need, we'll find a way (like we did with Covid vaccines which nobody thought of in 2018).

Fire is threatening the giant trees in Sequoia National Park. Those trees have lived around 2500 years and are now at risk. Maybe coincidence, maybe natural cycle, or maybe we have something to do with it. Look at 0:15. That's symbolic of what we are doing about this problem.
