A new study published in Geophysical Research Letters suggests that intense solar activity may influence Earth’s weather far more quickly than previously understood. While scientists have long known that the Sun’s approximately 11-year activity cycle affects Earth’s atmosphere over extended periods, the latest research indicates that geomagnetic storms can trigger measurable weather changes within hours …
Over the past 2.58 million years — a period scientists call the Quaternary — Earth’s climate has swung repeatedly between cold glacial periods and warmer interglacials. A new study in Nature Communications uses a GCM (General Circulation Model) paired with a faster statistical model called an emulator to investigate what drives these shifts. Because running …
Countries around the world are increasingly turning to tree-planting initiatives as a natural solution to climate change, but new research suggests that the effectiveness of these efforts depends less on the number of trees planted and more on where they are located. A recent study by ETH Zurich demonstrates that reforestation strategies can achieve similar …

Weather forecasts and long-term climate projections may seem almost magical, but they rest on decades of scientific and computational advances. The Earth system is an intricate network of interacting components: oceans circulate heat across basins, forests exchange carbon with the atmosphere, storms redistribute moisture and energy, and human activities alter atmospheric composition. All of these …
In 2008, atmospheric scientist Chris Bretherton flew through clouds above the Atacama Desert aboard an instrument-packed C-130 aircraft, gathering data on ice, water vapor, and air pressure. His goal was not sightseeing but confronting one of climate science’s hardest problems: understanding clouds. Nearly two decades later, as global temperatures have risen by about half a …

Terrestrial ecosystems are vital to regulating Earth’s climate by removing carbon dioxide (CO2) from the atmosphere through photosynthesis. This process, known as gross primary production (GPP), represents the largest carbon flux on Earth and serves as the foundation of the global carbon cycle. However, accurately quantifying GPP has been a longstanding challenge due to uncertainties …
Last year set a grim record as the hottest year ever documented, with unprecedented ocean temperatures and accelerated glacier melts, prompting a scramble among scientists to determine the underlying causes. While the primary suspects included the usual culprits—greenhouse gas emissions from fossil fuels and the natural El Niño phenomenon—these factors alone could not fully account …
The burgeoning field of climate attribution science has significantly advanced our understanding of the extent to which the climate crisis is responsible for extreme weather events that claim lives and devastate communities globally. These studies employ methodologies that rigorously compare historical data with current climatic events to elucidate the influence of human-induced global heating on …
Scientists are exploring the role of sand and dust particles in our climate and weather systems, focusing on a surprising location: Iceland. Unlike typical deserts with orange sandy dunes, Iceland’s vast desert areas—covering 44,000 km²—are flat expanses of black volcanic dust. These areas produce particles known as HLD (High-Latitude Dust), which originate near the Arctic …

Extreme weather events, by definition rare, have always demonstrated the climatic extremes our planet can endure, including ferocious storms, severe heatwaves, and intense cold snaps. However, with the rapid warming of Earth’s climate primarily due to the burning of fossil fuels, the spectrum of possible weather conditions—including extreme weather events—is expanding and altering. This alteration …
