Global Warming

Global warming is unfolding before our very eyes. And when it unfolds enough, it is catastrophic. It will get worse and worse unless humanity somehow undertakes a radical change of course. These videos dramatically illustrate the problem:

Climate: What’s the Worst That Could Happen?

Capture of Carbon Dioxide from the Atmosphere

Can we stop climate change by removing CO2 from the air?
From the video’s description: “Could we cure climate change? Geoengineering researcher Tim Kruger wants to try. He shares one promising possibility: using natural gas to generate electricity in a way that takes carbon dioxide out of the air. Learn more — both the potential and the risks — about this controversial field that seeks creative, deliberate and large-scale intervention to stop the already catastrophic consequences of our warming planet.”
Bill Gates-Backed Carbon Capture Plant Does The Work Of 40 Million Trees
From the video’s description: “In Squamish, British Columbia, there’s a company that wants to stop climate change by sucking carbon dioxide out of the atmosphere. It’s called Carbon Engineering, and it uses a combination of giant fans and complex chemical processes to remove carbon dioxide from the air in a procedure known as Direct Air Capture. Direct Air Capture isn’t new, but Carbon Engineering says its technology has advanced enough for it to finally make financial sense.”
A new way to remove CO2 from the atmosphere
From the video’s description: “Our planet has a carbon problem — if we don’t start removing carbon dioxide from the atmosphere, we’ll grow hotter, faster. Chemical engineer Jennifer Wilcox previews some amazing technology to scrub carbon from the air, using chemical reactions that capture and reuse CO2 in much the same way trees do … but at a vast scale. This detailed talk reviews both the promise and the pitfalls.”

How to green the world’s deserts and reverse climate change | Allan Savory
From the video’s description: “‘Desertification is a fancy word for land that is turning to desert,’ begins Allan Savory in this quietly powerful talk. And terrifyingly, it’s happening to about two-thirds of the world’s grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes — and his work so far shows — that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.”
