I am sometimes asked which single impact of climate change I think will be worst. I usually say that nothing keeps me up at night as much as Bangladesh. A country with over 174 million people (more than Canada, Italy, and the UK combined) living in an area less than one third the size of California.

Conversation I just had walking home around Columbia University: Cop: "You can't go through here." Me: "Why, is it illegal?" "This street is closed." "I don't understand, is it illegal for me to go through?" "I'll stop you if you do." "Right, but is it against the law? This is a public street." 1/

I urgently encourage everyone, everywhere to read Stephen Miller's full account of his deportation plans Key points: - "Large-scale staging grounds near the border" - Large-scale raids across the country - Deputizing red state National Guards to raid in red and blue states - 10 million deportations

Text, reading: "Joe Biden has led illegal aliens from well over a hundred countries by the millions. So just imagine the logistics involved in getting illegal aliens back to Pakistan, Cambodia, and yes, Mexico, the Northern Triangle, Brazil, South America, Panama, China, all throughout the Middle East, and so on and so forth, all throughout the continent of Africa. It is an undertaking every bit as significant and every bit as daring and ambitious, for example, as building the Panama Canal. It is a great undertaking. And so President Trump has outlined a plan that involves building large-scale staging grounds near the border, most likely in Texas because of the existing infrastructure there, right, the roads, the jeeps, the aircraft, the personnel. And so right now when we think of Border Patrol processing facilities, right, we think under the Biden administration of intake facilities. President Trump is going to build output, throughput facilities. So you go around the country arresting illegal immigrants in large-scale raids."Text, reading, "You have to have somewhere to put them. Again, because if you do a raid, let's say you go to a food processing facility where you know there's a lot of illegal workers. That raid might net illegal aliens just that one raid, right, from two dozen countries. So most countries will refuse to let you take back an alien from a different country. Mexico is not taking illegal aliens from Vietnam, and you could force them back, of course, but that's also a much quicker trip, right, if you're a Vietnamese illegal alien, it's much more inconvenient to be sent back to Vietnam. So you build these facilities where then you're able to say, you know, hypothetically, three times a day are the flights back to Mexico. Two times a day are the flights back to the Northern Triangle, right. On Monday and Friday are the flights back to different African countries, right."Text, reading, "On Thursday and Sunday are the flights back to different Asian countries. So you create this efficiency by having these standing facilities where planes are moving off the runway constantly, probably military aircraft, some existing DHS assets. And that's how you're able to scale and achieve the efficiency. Then in terms of personnel, you go to the red state governors and you say, give us your National Guard. We will deputize them as immigration enforcement officers. They know their states, they know their communities, they know their cities. So it's not like you're asking somebody to move away from their family, away from their home. This is sometimes a complaint as well. You take a National Guardsman from Alabama, you know, you put him on a border assignment for two years and he'd be away from his loved ones and so forth."Text, reading, "Well, you solve that problem. The Alabama National Guard is going to arrest illegal aliens in Alabama and the Virginia National Guard in Virginia. And if you're going to go into an unfriendly state like Maryland, well, there would just be Virginia doing the arrest in Maryland, right, very close, very nearby. So you have experienced ICE veterans who are leading the operations and then you scale up the personnel by bringing in both other federal law enforcement officers, you know, think DEA, ATF, et cetera, and then the National Guardsmen. And then we're the ones who provide them to state and local sheriffs as well, too. That's the basic idea logistically for how you're able to carry out a deportation operation at that monumental magnitude. So let me add, let's just go through scale here. How many people, how many foreign national invaders will America have because of Biden at the end of four years? Well, I mean, even using conservative numbers, I mean, you're going to be looking at 10 million illegals that Biden would have let in."

New dystopia just dropped (Currently #3 in my personal list of most dystopian papers, after the one showing that congress members vote for war more often after their sons leave conscription age, and the one measuring what happens to patients when private equity firms acquire elder care facilities)

This is really, really stupid. And the first thing I've seen since the US election that could really hurt the LPC. They need to immediately fire those responsible and completely disavow this kind of thing to regain a credible claim to respectability. www.cbc.ca/news/politic...

How delulu is it to expect the U.S. to bring "Chinese peasants" to their knees through tariffs? 1. China's GDP (PPP) is larger than the U.S., Canada, Mexico, and Australia combined. 2. Exports to the U.S. account for 2.8% of Chinese GDP.

As an economist who studies housing among other things, "You can't have cheap housing unless the government admits a large number of unskilled immigrants" is not only wrong, it sounds like a hostage negotiation. www.cbc.ca/news/canada/...

Maybe the most radical opinion I have is: I really think they are going to deliberately and irrevocably destroy the SSA, IRS, and treasury codebases. I don't think many people realize that or understand what it will mean The state effectively ceases to exist when it can no longer process payments.

Climate change is an environmental issue – but it’s not only an environmental issue. It affects our health, and the economy. It impacts food, water, and resources. It contributes to geopolitical instability and even conflict. Here are the Canadian scientists who study this.
