For decades, rising carbon emissions have accelerated climate change, but this year marked a critical turning point that could finally reverse that trend. Renewable energy has now graduated beyond the need for subsidies and incentives, emerging as a cheaper alternative to fossil fuels in many countries. News Editor Tim Appenzeller and policy expert Li Shuo describe the economic forces behind this shift, and the obstacles that remain to the continued rise of green energy.This is the same good news reported in PBS Terra says 'We Just Crossed Our FIRST Tipping Point… And It’s NOT What You Think'.

1:15 The graph has mislabeled trend lines. "Other renewables" generate more energy than hydropower alone.
Unlike passing the other tipping points, like the AMOC, permafrost, West Antarctic ice sheet, and coral reefs, passing the renewable energy tipping point is good news. I wrote about it in DW News asks 'Earth Overshoot Day: What can we do to try live within the planet’s limits?'Science Magazine's video is shorter and more focused than PBS Terra's, so it's one I'm more likely to show to my students. Again, welcome to blogging as professional development.[C]onvincing people to be less wasteful, particularly creating less food waste and eating less meat, especially beef, would be helpful. [One] could consider that to be a technology. So is renewable energy. Between the two, it would move Earth Overshoot Day back more than a month. Progress!Yes, it is, and it's good news I can share with my students. Welcome to blogging as professional development.
