Doubt Cast on Carbon Capture by Stanford Study – “It Usually Increases Air Pollution”

Syria Update: Turkish Ground Operations

SYRIA UPDATE: Yesterday, Turkey began ground operations into Syria. Their goal is to take two predominantly Arab cities, Tel Abyad and Ras al-Ayn, that are controlled by the Kurdish-aligned Syrian Democratic Forces. Taking those two cities will cut the main highway connection between the main Kurdish population centers in Kobane canton (to the west) and Cizire canton (to the east).

Elizabeth Warren's Climate Policy

Elizabeth Warren has been releasing a trickle of climate change policy for what feels like 40 or 50 years now, on such hot issues as fossil fuel leasing on public lands and how much greenhouse gases our military bases emit. As much as I like Warren, I've found her approach to climate policy to be extremely irritating.

Now, at long last, she's finally released the meat and potatoes of her plan. Let's take a look at what she has to say.

Some questions I hope to see:

Period of Change in Yemen?

I'm starting to think I need to figure out what's going on in Yemen. I've mostly been ignoring the conflict, but it looks like it could be approaching a period of change.

Jay Inslee vs Joe Biden

This strikes me as slightly unfair. It is certainly true that the emissions reductions by 2030 matter more than the exact year in was which we reach net zero. (There's expected to be a long period before we reach net zero in which net emissions are extremely low, so a few more years of low emissions won't add substantially to our cumulative emissions. On the other hand, even one more year at our current level of emissions will eat pretty noticeably into our carbon budget.) It's also true that Biden's plan doesn't currently specify a 2030 reduction target.

Impeachment scenarios

One interesting thing about the current political situation is that I have literally no idea what's going to happen. Here are a few possibilities:

A) The House votes to impeach, but Mitch McConnell refuses to allow a vote in the Senate. Trump carries out the rest of his term under a cloud. During the debates, Biden calls him a coward and struts around him while clucking like a chicken. The Biden-Buttigieg ticket ekes out a narrow 291-247 victory in 2020. America reaches net zero emissions in 2049.

NET Power Zero Emissions

If the numbers in this article are even remotely accurate, this is a game changer for the fight against climate change, and sets the stage for a major fight within the environmental movement.

Negative Emissions and Carbon Pricing

One of the problems with carbon pricing is that it's difficult to use for negative emissions. Let's say that you set the price of carbon at the cost of removing the carbon from the atmosphere. That lets you get to net zero emissions, but it doesn't do anything about existing emissions. Now let's say that you increase the price on carbon to, let's say, 150% of the cost of CDR (Carbon Dioxide Removal). That lets you go net negative, but only by a certain amount. It's hard to calculate what percent of CDR your carbon price needs to be, since it depends on so many different factors.

Biden's Climate Plan

I'm finally sitting down and reading through Biden's climate plan, and it is really, really similar to Beto's. It was a smart move by Beto to get his climate plan out first, even though it wasn't really done, because it makes it look like everyone else is imitating him. (The exceptions to this are Jay Inslee, who imitates no one, and John Delaney, who's imitating Milton Friedman.)

Some highlights:

"Ensure the U.S. achieves a 100% clean energy economy and reaches net-zero emissions no later than 2050."
