When a University of Michigan-led research team reported last year that North American migratory birds have been getting smaller over the past four decades and…
The period preceding the emergence of behaviorally modern humans was characterized by dramatic climatic and environmental variability – it is these pressures, occurring over hundreds…
Analysis of 260 million years of major geological events finds recurring clusters 27.5 million years apart. Geologic activity on Earth appears to follow a 27.5-million-year…
Study sheds light on the future of the massive Thwaites Glacier. The world’s largest ice sheets may be in less danger of sudden collapse than…
New research finds that moving off the coast and away from floods can expand options. University of Delaware disaster researcher A.R. Siders said it’s time…
Researchers have found that Earth’s energy imbalance approximately doubled during the 14-year period from 2005 to 2019. Earth’s climate is determined by a delicate balance…
Ice core samples reveal significant smoke aerosols in the pre-industrial Southern Hemisphere. Centuries-old smoke particles preserved in the ice reveal a fiery past in the…
New estimates suggest Central and South America and South-East Asia most affected regions. Between 1991 and 2018, more than a third of all deaths in…
By combining satellite data and digital models, the researchers have shown that coastal overtopping, and consequently the risk of flooding, is set to further accelerate…
Tiny charged electrons and protons which can damage satellites and alter the ozone have revealed some of their mysteries to University of Otago scientists. In…
Ozone is a pollutant at ground level, but very high in the atmosphere’s “ozone layer,” it absorbs damaging ultraviolet radiation. Past studies have examined ozone…
The accuracy of climate predictions depends crucially on how the ocean circulation of the North Atlantic is incorporated into climate models, study shows. Thirty state-of-the-art…
Methane-eating microbes help regulate Earth’s temperatures with remarkably high metabolic rates within seafloor carbonate rocks. Methane is a strong greenhouse gas that plays a key…
Research based on ice-thickness data from ESA’s CryoSat and Envisat missions along with a new model of snow has revealed that sea ice in the…
In the heart of their Antarctic habitat, krill populations are projected to decline about 30% this century due to widespread negative effects from human-driven climate…
A study of woodland ecosystems that provide habitat for rare and endangered species along streams and rivers throughout California reveals that some of these ecologically…
Climate change associated with emerging disease spread. Humans are creating or exacerbating the environmental conditions that could lead to further pandemics, new University of Sydney…
A new analysis of satellite cloud observations finds that global warming causes low-level clouds over the oceans to decrease, leading to further warming. The work,…
