If we continue on our business-as-usual trajectory of unchecked greenhouse gas emissions, the toddlers riding on their parents’ shoulders and the teens entering their senior year of high school will inherit a planet beset by rising seas, withering heat, wild weather swings, mass animal, bird and plant extinctions, and potentially billions of environmental refugees displaced by forces of a human made disaster.
This future is neither acceptable nor inevitable, proclaimed the millions of protesters in hundreds of cities worldwide who held a climate strike  on Sept. 20. Uganda, India, Nepal, New Zealand, Sweden, the US — and Halifax Mall in Raleigh: They protested the malfeasance of global leaders who are doing too little — or nothing — to thwart the worst effects of climate change.
President Trump is among the world’s worst climate offenders. His administration has repealed, or proposed to repeal, crucial rules that limited methane — a potent greenhouse gas 85 times more potent than carbon dioxide. Under his leadership, the EPA weakened pollution controls on new and expanding power plants, proposed weakening fuel-economy standards for cars and trucks, as well as 20 more rollbacks on air pollution and greenhouse gas emissions.
In Raleigh, just feet from the hub of state government, itself leaden and largely ineffective, high schoolers hoisted signs: “There is no Planet B,” “Our Gen Will Pay,” “Act As if Our House Is On Fire.”
The air was redolent of burning sage as members of the Saponi nation spoke of hope: “We believe that when we gather inside that sacred circle, no matter how small or how big, and we have love, harmony, and balance in our heart, then anything in the entire universe is possible in that space.”
An entire week of action is underway: Go to www.strikewithus.org  for details.
