Climate News I've Seen (esp the third)

There's too much climate news to keep track of anymore, but here are a few recent items I've come across:

• Students are now required to take a course in climate change in order to graduate from the University of California at San Diego. Forty different versions that meet the requirement will be offered. The article says, "...at least 30% of a course's content must be related to climate, and the class must address two of these areas: scientific foundations, human impacts, mitigation strategies, and project-based learning." I'd choose scientific foundations and mitigation strategies, but that's just for me. Irrelevant fact: I took Introduction to Statistics from the psychology department to fulfill my college's social science requirement. I knew most of it from high school. It wasn't a good choice, in retrospect, as I took very few "soft" courses in college; it was almost all math & physics


• The Independent: "...hurricanes as intense as Helene, which were once expected to occur every 130 years, are now likely to happen every 53 years – about 2.5 times more frequently." 
• "A separate analysis of Helene last week by Department of Energy Lawrence Berkeley National Lab scientists determined that the climate crisis caused 50 per cent more rainfall in some parts of Georgia and the Carolinas, and that observed rainfall was “made up to 20 times more likely in these areas because of global warming."


• UniverseToday.com: Advanced Civilizations Will Overheat Their Planets Within 1,000 Years
• "Earth’s average global temperatures have been steadily increasing since the Industrial Revolution. Depending on the extent of temperature increases, the impact on Earth’s habitability could be catastrophic. In a recent study, a team of scientists examined how temperature increases are a long-term issue facing advanced civilizations and not just a matter of fossil fuel consumption. As they argue, rising planetary temperatures could be an inevitable result of the exponential growth of energy consumption. Their findings could have serious implications for astrobiology and the Search for Extraterrestrial Intelligence (SETI)."
• Here's a preprint of the study: "Waste Heat and Habitability: Constraints from Technological Energy Consumption," Amedeo Balbi et al, arXiv 9-Sept-2024. The analysis is very simple physics. Here's a key figure:

• Mind, this has nothing to do with fossil fuels. It's only about how much power the planet uses--could be solar, could be nuclear (fission or fusion), geothermal, FFs -- because the problem is waste heat from the machines run by our power sources, not the type of power sources.
