Barnacles can tell a whale of a tale. Chemical clues inside barnacles that hitched rides on baleen whales millions of years ago could divulge ancient whale migration routes, new research suggests.
Methane wasn’t the cozy blanket that kept Earth warm hundreds of millions of years ago when the sun was dim, new research suggests.
Humankind’s bombs, plastics, chickens and more have altered the planet enough to usher in a new chapter in Earth’s geologic history. That’s the majority opinion of a group of 35 experts tasked with evaluating whether the current human-dominated time span, unofficially dubbed the Anthropocene, deserves a formal place in Earth’s geologic timeline alongside the Eocene and the Pliocene.
A natural ally against global warming may provide far less aid than previously hoped.
As chief scientist for a voyage of the research vessel Endeavor, oceanographer Melissa Omand oversaw everything from the deployment of robotic submarines to crew-member bunk assignments. The November 2015 expedition 150 kilometers off Rhode Island’s coast was collecting data for Omand’s ongoing investigations of the fate of carbon dioxide soaked up by the ocean.
New experiments have re-created the genesis of Earth’s first continents.
Sea ice around the North Pole has reached its second-lowest low on record, tying with 2007, scientists at NASA and the National Snow and Ice Data Center announced September 15.
A stretch of ocean off the coast of Cape Cod more than four times the size of Rhode Island has become the first U.S. marine national monument in the Atlantic Ocean.
What, if any, steps do you think the United States should take to combat climate change and why, or why not?
Collection of articles written on the science-related policy positions of Hillary Clinton and Donald Trump. I researched and wrote the section on climate change.
A melting snow patch in Greenland has revealed what could be the oldest fossilized evidence of life on Earth. The 3.7-billion-year-old structures may help scientists retrace the rise of the first organisms relatively soon after Earth’s formation around 4.5 billion years ago, the discoverers report online August 31 in Nature.
