Latest Paleocene–Eocene Thermal Maximum Stories
This isn't the first time global warming has occurred. But will we survive it again?
Some 56 million years ago, a massive pulse of carbon dioxide into the atmosphere sent global temperatures soaring. In the oceans, carbonate sediments dissolved, some organisms went extinct and others evolved.
While scientists have known for several years that some mammals became smaller during a period of warming known as the Paleocene-Eocene Thermal Maximum, researchers have found a second instance of mammalian “dwarfing” attributable to increasing temperatures.
A new study, led by Scripps Institution of Oceanography, reveals the look of the oceans will change drastically in the future as the coming greenhouse world alters marine food webs and gives certain species advantages over others, if history's closest analog is any indication.
Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago.
A series of global warming events called hyperthermals that occurred more than 50 million years ago had a similar origin to a much larger hyperthermal of the period, the Pelaeocene-Eocene Thermal Maximum (PETM), new research has found.
The world’s oceans may be acidifying more rapidly than they have at any time in the past 300 million years due to high levels of pollution, according to research published this week in the journal Science.
The ancient sifrhippus, the earliest known horse, lived around 50 million years ago. It was very distinct in its appearance because it was only about the size of a modern day house cat, weighing in around 12 pounds.
Rice researchers show ocean could have contained enough methane to cause drastic climate change.
Warmer temperatures and a lack of water are causing some types of plants and animals to become smaller, claims a new study published Monday in the journal Nature Climate Change.
