Thank you for sharing Seth Borenstein’s article “Looking for signs of global warming? They’re all around you,” on June 19th.
For over 10,000 years nature kept CO2 in balance at 280 ppm. When Bill McKibben wrote “The End of Nature” in 1989, CO2 had already passed the safe upper limit of 350 ppm. It is now at 411. It means we are breathing man-made air. The end of nature.
We monitor our children daily for anything that looks suspicious from spots and rashes to labored breathing, but we ignore the vital signs of their life support system. My 33-year-old son has never experienced a month of below average global temperatures or breathed air with a safe level of CO2.
Please continue to report on the accelerating changes to our natural world. No one is coming to ensure our children have a livable climate. We need an informed public to demand urgent action.
