A new study reconstructs roughly 800 years of streamflow history in India’s major rivers, showing an increase in synchronous drought linked to anthropogenic climate change.

El Niño May Be Driving Insect Decline in the Tropics
Stronger and more frequent El Niño events are contributing to a decline in arthropod diversity and population, as well as to a reduction in the ecological services the animals provide.
Tree Rings Record History of Jet Stream-Related Climate Extremes
Persistent spatial patterns of summer weather extremes in the northern hemisphere recorded in tree ring growth records provide a thousand-year history of jet stream ‘wave5’ dynamics.
Decadal Forecasts with a SMYLE
Scientists use a large suite of simulations with an established climate model to predict the Pacific Decadal Oscillation up to one year in advance, but El Niño can still get in the way.
Two Equations that Unlock El Niño
Despite the El Niño–Southern Oscillation’s global reach and complex ocean–atmosphere interactions across timescales, two simple, elegant equations capture its key dynamics and defining properties.
Busy Hurricane Season Expected in 2025
A new NOAA report predicts an active Atlantic hurricane season, though global weather patterns could still shift predictions.
The Interplay of ENSO and Immunity in Infectious Disease Outbreaks
El Niño and La Niña events can affect the spread of infectious diseases including cholera and dengue fever. The effects of some diseases may persist over several years.
Three Studies Point to El Niño as Key to 2023 Record Global Heat
Three recent studies reveal how the interplay between El Niño and long-term global warming drove the record-breaking global temperatures of 2023.
“Exceptional” Global Warming Spike Continued in 2024
More than 3 billion people experienced their hottest year ever in 2024 because of anthropogenic climate change. The world is speeding toward its 1.5°C warming target.
Darker, Less Cloudy Earth Contributed to Record Heat
Decreases to our planet’s albedo caused by fewer low-lying clouds helped push temperatures to historic highs in 2023, according to new research.
