Ninety Sky is a weather forecasting system that treats precipitation predictions as probabilities, updating minute-by-minute based on radar data, weather models, and a classification model called Jev that judges combined inputs. The system shows higher accuracy than individual sources across multiple lead times and climates, with calibration to ensure forecast probabilities match actual rainfall frequency.
On the autumn equinox of September 23, 2026, the sun will rise due east from everywhere on Earth. The article describes an interactive visualization showing solar position calculations using NOAA's Solar Calculator and astronomical algorithms, useful for understanding equinox geometry rather than navigation.
A record-breaking El Niño is heating the Pacific Ocean to 3.05°C, surpassing the previous 2015 record months ahead of its expected peak, with forecasts predicting temperatures could reach 4.0°C by late 2023. This super El Niño, likely the largest in 1,000 years, is combining with human-caused global warming to intensify extreme weather globally, including devastating wildfires in Indonesia, droughts in Central America, and flooding in Peru and Chile, with scientists warning it could push 50 million people into acute hunger.
