Climate Reality: Pittsburgh & SWPA 🌎

Lonnie Thompson went to the ends of the Earth and above the clouds to document and understand the effects of the climate crisis on our planet. Across the highest mountain ranges, from the Andes to the Himalaya, his physically arduous and heroic research revealed the rapid decline of the world’s highest glaciers. And his meticulously documented findings from the ice cores he carried back down the mountains had an impact far beyond the scientific community. His lifelong determination to communicate what he discovered about the global impact of the climate crisis with policymakers and the public was extraordinary. For more than three decades, Lonnie and his wife and scientific collaborator Ellen Mosley-Thompson were trusted advisors to me and many others on climate science. Lonnie was an invaluable ally in the global movement to solve the climate crisis and was a cherished friend I will miss dearly. nytimes.com/2026/11/06/scien…
