The climate emergency is creating a public health emergency by increasing risks for heat stress, vector-borne diseases, and traumatic injuries as well as disrupting healthcare access. Also, 2023 saw some notable environmental decisions in U.S. federal and state courts, from the Supreme Court’s removal of some wetlands protections to the landmark win for youth plaintiffs in a Montana climate case.  And 2023 is likely to go down in history as the hottest year ever seen by humans. But we still have a chance to rein in global warming before it runs too hot for our civilization, says UPenn Professor Michael Mann, whose latest book is Our Fragile Moment: How Lessons from Earth’s Past Can Help Us Survive the Climate Crisis.  -- As a non-profit media organization we could not produce high-quality journalism that educates and inspires you to be fully informed about climate change and environmental issues without your help.
