Jong-Seong Kug said that El Niño and climate change may be locked into a vicious climate cycle. The study findings suggest global heating amplifies the impacts associated with super El Niños, and “makes the climate system more prone to persistent shifts once those impacts are triggered.” “Super El Niño can shift the background climate conditions that people and ecosystems rely on.” By Bob Berwyn, in April 2026: https://insideclimatenews.org/news/25042026/el-nino-earth-warming/

Atmospheric water vapour drives many important weather phenomena such as precipitation and drought. The atmosphere *can* hold about 7% more water for every 1 °C (1.8 °F) rise in temperature. The model is that saturation vapour pressure increases approximately *exponentially* with temperature under typical atmospheric conditions. Under humid conditions, the rate at which perspiration evaporates on the skin is lower than it would be under arid conditions. With a dew point at 20° C (70° F), almost everyone feels "sticky". When the air above the dew point is cooled, its moisture capacity is reduced, and when the temperature passes below the dew point, water vapour will condense, or precipitate, to form liquid water. The dew point increases by about 1°C for every 5% increase in relative humidity (the ratio of how much water vapour is in the air to how much water vapour the air can contain).
