When the Thomas Fire raged through Ventura and Santa Barbara counties in December 2017, Danielle Touma, at the time an earth science researcher at Stanford, was stunned by its severity. Burning for more than a month and scorching 440 square miles, the fire was then considered the worst in California's history.
ETH Zurich researchers conducted an experiment to investigate the initial steps in the formation of aerosols. Their findings are now aiding efforts to better understand and model that process - for example, the formation of clouds in the atmosphere.
Wetland methane cycling increased during a rapid global warming event 56 million years ago and could foreshadow changes the methane cycle will experience in the future, according to new research led by the University of Bristol.
The first COVID-19 lockdowns led to significant changes in urban air pollution levels around the world, but the changes were smaller than expected - a new study reveals.
Many of the most advanced climate models simulate smoke that is darker, or more light absorbing, than what researchers see in observations.
ASU School of Earth and Space Exploration scientist Amanda Clarke and her team have been working to solve the mysterious root cause of the Sunset Crater eruption and any lessons learned to better understand the threats similar volcanoes may pose around the world today. But as to why it erupted, that has remained a mystery, until now. Clarke's group is among the first to show the importance of carbon dioxide in volcanic eruptions.
Roughly two billion years ago, microorganisms called cyanobacteria fundamentally transformed the globe. Researchers are now stepping back to that pivotal moment in Earth's history.
A new study led by researchers at the Universities of Bristol, Exeter, and Bath helps to shed light on the winter weather we may soon have in store following a dramatic meteorological event currently unfolding high above the North Pole. Weather forecasting models are predicting with increasing confidence that a sudden stratospheric warming (SSW) event will take place today, 5 January 2021.
Although stellar flares are typically viewed as a detriment to habitability, study shows "life might still have a fighting chance." Researchers find that flares drive a planets atmospheric composition to a new chemical equilibrium.
Land ecosystems currently play a key role in mitigating climate change. The more carbon dioxide (CO2) plants and trees absorb during photosynthesis, the process they use to make food, the less CO2 remains trapped in the atmosphere where it can cause temperatures to rise. But scientists have identified an unsettling trend - as levels of CO2 in the atmosphere increase, 86 percent of land ecosystems globally are becoming progressively less efficient at absorbing it.
