100 Solutions for global warming

This TED talk from 2018 discusses the research and conclusions from Project Drawdown.  Drawdown is when concentrations of CO2 in the atmosphere begin to decline on a year-to-year basis. The Project Drawdown organization has been evaluating a variety of solutions for both reducing CO2 emissions and removing CO2 from the atmosphere.  100 solutions are described in the book that summarizes their research and evaluation.  You really need to watch the video to get a good understanding of their work, but here are a few highlighted quotes from the video. 

• “We would want to implement these solutions whether or not global warming was even a problem, because they have cascading benefits to human and planetary well-being.” “When we implement these solutions, we shift the way we do business from a system that is inherently exploitative and extractive to a new normal that is by nature restorative and regenerative. We need to rethink our global goals, to move beyond sustainability towards regeneration, and along the way reverse global warming.”
• “What surprised us, honestly, was that eight of the top 20 relate to the food system. The climate impact of food may come as a surprise to many people, but what these results show is that the decisions we make every day about the food we produce, purchase and consume are perhaps the most important contributions every individual can make to reversing global warming.”
• “A plant-rich diet is not a vegan or a vegetarian diet, though I applaud any who make those choices.  It's a healthy diet in terms of how much we consume, and particularly how much meat is consumed. Moreover, approximately a third of all food produced is not eaten, and wasted food emits an astounding eight percent of global greenhouse gases.”
• “The single most impactful solution, according to this analysis, would be refrigeration management, or properly managing and disposing of hydrofluorocarbons, also known as HFCs, which are used by refrigerators and air conditioners to cool the air.”
• “Rooftop solar comes in ranked number 10.”
