atmosphere
Scientists have presented new discoveries about the way heat and energy move and manifest in the ionosphere, a region of Earth’s atmosphere that reacts to changes from both space above and Earth below.
Somewhere between Earth's creation and where we are today, scientists have demonstrated that some early life forms existed just fine without any oxygen.
Researchers studied storm development from the Pliocene era, roughly three million years ago, because it was the last time Earth had as much carbon dioxide as it does now.
"This is a major milestone in our understanding of the atmosphere. The CERN experiment is unique, and it has produced data that seemed completely out of reach just five years ago."
Forecasters are saying that La Nina is expected to influence winter conditions this year, likely developing in late fall or early winter.
The risk of a 35+ year megadrought in the American Southwest likely will rise from a low chance over the past thousand years to a 20- to 50-percent chance in this century.
During the past 100 years, atmospheric oxygen has declined by a "speedy" 0.1 percent because of the burning of fossil fuels, researchers say.
Besides providing information about the atmospheres of other planets, cosmic dust can impact radio communications, climate and even serve as fertilizer for phytoplankton in the oceans.
