Topic: La Nina

NASA Chief Scientist Kate Calvin appeared on CBS Face the Nation with Margaret Brennan to discuss extreme global temperatures. Calvin explained that the transition from La Nina to El Nino, combined with long-term climate change, is driving record heat waves. The interview touched on rising ocean temperatures and the impact of these cycles on global ecosystems.

Brazil is experiencing its worst drought in 91 years, causing water levels in the Parana River to reach historic lows. The resulting energy shortage has led to increased electricity tariffs and food inflation, putting pressure on the government of President Jair Bolsonaro. While climatologists point to the La Nina effect, many are using the event to advocate for global climate change policies.
