I put to you that it is very difficult to overlook the following two implications from recent climate science:

• Greenhouse gases are not the only anthropogenic emissions that strongly interfere with the global and regional climate
• We are already in the danger zone, and given that CO2 lives in the atmosphere for hundreds of years, CO2 reductions alone are very unlikely to help us avoid near-term tipping points in the earth’s thermostat

Like most people, you’ve probably heard about it, but are not entirely sure what it is. You are not alone.
