I can understand why governments would push for something like this after 9/11, though it of course goes without saying that this is a totally unacceptable violation of someone’s basic rights. It also goes without saying that governments always want more control over their citizens, but what exactly are they so worried might happen, right now, in 2025 or the near future?
We are realistically looking at losing between 200 million and 1 billion people over the next 20 years due to climate-change induced famine and heat stroke. Those are realistic estimates. More optimistic scenarios could make that number less, more pessimistic ones could reduce it. We are on the eve of what future histories may refer to as the Great Hunger.
Even for those lucky enough to not live in regions being rendered uninhabitable, the quality of life for the average citizen is collapsing. The developing world will experience mass famine. The developed world will experience food prices not seen since the advent of mechanized agriculture. Home prices will continue to become more unaffordable, as more and more homes are destroyed by rapidly increasing natural disasters. In the US, tens of millions of homeowners are going to have their primary asset, their homes, rendered completely worthless after they become uninsurable. Governments can try to prop up the insurance market if they want, but not even national governments have the resources to subsidize an insurance market in an era of spiraling natural catastrophes.
Leaders around the world see a future of chaos, famine, and strife. Really all the Four Horseman are coming out. In developed countries, leaders fear millions of desperate poor people from developing countries trying to cross their borders. Internally, they fear violence by their own populations, who are seeing their standard of living rapidly collapse.
The borders are being locked down. The walls are going up. People everywhere are being increasingly surveilled and controlled. Political leaders might be cynical enough to deny climate change for political gain, but that doesn’t mean they’re ignorant to the actual future we’re running headfirst into. Technology is also advancing, allowing “mass shooter” type individuals to potentially cause much larger acts of destruction in the future.
Most governments would prefer to maintain power by actually improving the lives of their citizens. That’s the safest and most moral approach. But in a world of rapidly spiraling climate change, governments simply are not capable of on improving the lives of their citizens. They can’t even maintain the standard of living their citizens already have. So, the leaders have to turn to more brute force methods to retain control. Best to be loved. But if you can’t be loved, then at least be feared.
Who’s “we”?

“The world’s population is projected to continue growing for the next 50 to 60 years, peaking at approximately 10.3 billion by the mid-2080.[sic]”
Those projections assume agricultural yields have no effect on human well being or numbers. They don’t factor in climate induced bread basket collapse.
