2025 was the third hottest year ever.
Trend is worrying and faster than expected a few years ago.

Only when we stop burning coal, oil and gas, temperature will stop rising.

In 2026, Climate Change Is No Longer A Theoretical Risk In 2026, climate change threatens human safety, natural systems & economic stability, as data shows accelerating warming, stronger storms, rising seas and growing losses.

“The data shows a planet warming faster than policy response, storms intensifying alongside rising seas, and economic losses concentrating where resilience is weakest. Climate risk is now a planning variable, rather than a forecast uncertainty.” www.forbes.com/sites/dianne...

The Amazon has more tree species in 2.5 acres than the entire US & Canada combined. The Congo is the only home to all 3 great apes: gorillas, chimpanzees, and bonobos.
We are losing libraries of life before we even read the books.
