I'm glad it's not all bad news. But models? That's a laugh. As a software engineer with a degree, summa cum laude, and 40+ years studying climate science, I'm quite familiar with the efficacy of climate models. And it's not good.
I prefer to look at paleoclimate history and gain a rough understanding for what climate will likely do from what it has done before.
The notion that so many places will become desert is nonsense! Deserts and droughts are the product of weather patterns plus the availability of water vapor for clouds and rain. In a warmer world, rain would become far more common. Not every location would enjoy the increased rain, but more places would get it. The opposite is true with global cooling. In fact, during the last glacial period of the current Ice Age, the cooler oceans evaporated such a smaller degree of water that deserts were far more common, including the polar deserts which covered much of North America and northern Europe. We know this because civilization was virtually impossible to start without the agriculture and its required abundance of rain.
If you look at the climate history for Earth over the last 4.5 Billion years, you'll see that a vast majority of that history was spent far, far warmer than today—and life thrived! The tropics were still filled with life, even with +10C of warmer climate. And the polar regions were lush gardens. Deserts were smaller, but with a deeper dryness.
Here's one of my more recent topics on global warming.
Thank you for sharing your insight and expertise! Good to know that this guy was off base on some levels, and I never believe everything I read so thank you for your comment and video. I think politicians (on both sides) stretch the truth today regarding global warming so it is nice to get differing opinions and facts on the topic.
