The Climate Dragon's Breath

Jason Box warns on the danger of letting carbon heat our planet. “Dragon Breath”—a warning of catastrophic climate change ahead?
What's the take home message, if you ask me? Because elevated atmospheric carbon from fossil fuel burning is the trigger mechanism poking the climate dragon. The trajectory we're on is to awaken a runaway climate heating that will ravage global agricultural systems leading to mass famine, conflict. Sea level rise will be a small problem by comparison. We simply MUST lower atmospheric carbon emissions. This should start with limiting the burning of fossil fuels from conventional sources; chiefly coal, followed by tar sands [block the pipeline]; reduce fossil fuel use elsewhere for example in liquid transportation fuels; engage in a massive reforestation program to have side benefits of sustainable timber, reduced desertification, animal habitat, aquaculture; and redirect fossil fuel subsidies to renewable energy subsidies. This is an all hands on deck moment. We're in the age of consequences.
There are still questions, of course, but the cautionary principle makes clear we have to keep this dragon in the ground.
