While banning ozone-destroying gases such as CFCs has helped the ozone layer to recover, when combined with increased air pollution the impact of ozone...
During the Paleocene-Eocene Thermal Maximum (PETM), a period of geological rapid warming and aridification approximately 56 million years ago, a flesh-eating...
The end-Permian mass extinction, which occurred about 252 million years ago, was the most severe extinction event in the past 540 million years, eliminating...
One-third of Mars’ surface has shallow-buried water, but it is currently too cold for use by life. Proposals to warm Mars using greenhouse gases require...
In a study published in the journal Frontiers in Ecology and Evolution, a team of scientists in South Africa assessed the effects of air temperature and...
Paleontologists in Argentina have identified a new species of eusauropod (true sauropod) dinosaur that lived 179 million years ago, just after the mysterious...
The end-Cretaceous mass extinction 66 million years ago eradicated roughly 75% of the animal and plant species on Earth, including whole groups like non-avian...
An international team of geologists has found the first direct evidence that volcanic eruptions in the southern part of the Siberian Traps region 252 million...
High levels of damaging ultraviolet-B (UV-B) radiation collapsed forest ecosystems and killed off many species of fish and tetrapods at the end of the...
Some 252 million years ago, intense volcanic activity belched massive volumes of greenhouse gasses into the atmosphere and triggered rapid changes to the...
A new study in the journal Science shows that two alpine bumblebee species have responded to a decline in flowering due to warming temperatures by evolving...
Warming temperatures are causing mosquitoes in Greenland to grow faster and emerge earlier, boosting their population and threatening the caribou they...
Short, rapid warming events, known as interstadials, coincided with major extinction events, according to a team of scientists from Australia and the United...
A group of scientists headed by Dr Jeremy Kerr from the University of Ottawa, Canada, has discovered that climate change is rapidly shrinking the area...
A team of researchers led by Jamin Greenbaum of the University of Texas at Austin has discovered two seafloor troughs that could allow warm ocean water...
A new study published in the journal Nature Climate Change has confirmed a long-standing prediction that snowfall in Antarctica will increase significantly...
