Kīlauea Volcano Episode 37 lava fountaining occurred On November 25, from 2:30 p.m. to 11:39 p.m., totaling just over 9 hours. Fountains were limited to the north vent, which sent lava flows over a large portion of the crater floor. Fountain heights reached 500-600 ft (150-180 meters). The south vent showed only weak spattering and flaming. USGS photo by M. Patrick. Kīlauea Volcano The telephoto shows lava flowing east across the floor of Halemaʻumaʻu crater, fed by the lava fountains in the west part of the crater. Preliminary estimates suggest that approximately 6 million cubic meters (7.8 million cubic yards) of lava were erupted during episode 37, based on ground deformation data. USGS photo by M. Patrick.

Upwelling Failure

For the first time since records began, the cold, nutrient-rich waters of the Gulf of Panama failed to emerge from depths of the ocean to rise to the surface.

Finding highlights climate’s impact on fundamental oceanic processes.

Ozone Hole Development 2025

Southern Hemisphere Ozone Hole Area

Ozone hole presented an early development, reaching a larger-than-average area mid-September.

Ozone Hole Development 2025 Southern Hemisphere Ozone Hole Area During the Southern Hemisphere spring season (August - October) the ozone hole over the Antarctic increases in size, reaching a maximum between mid-September and mid-October. When temperatures high up in the atmosphere (stratosphere) start to rise in late Southern Hemisphere spring, ozone depletion slows, the polar vortex weakens and finally breaks down, and by the end of December ozone levels have returned to normal. Since the ban on halocarbons, the ozone layer has slowly been recovering; the data clearly show a trend in decreasing area of the ozone hole. The ozone hole area is calculated as the area with ozone values below 220 DU south of 60S. Credit: CAMS/ECMWF
