94 million year-old climate change event holds clues for future
Description: A new study has found that parts of the ocean became inhospitable for some organisms as the Earth's climate warmed 94 million years ago. As the Earth warmed, several natural elements - what we think of as vitamins - depleted, causing some organisms to die off or greatly decrease in numbers. The elements that faded away were vanadium and molybdenum, important trace metals that serve as nutrients for ocean life. Molybdenum in particular is used by bacteria to help promote nitrogen fixation, which is essential for all forms of life. [Source: Florida State University]
