An international team of researchers has developed a computer model that makes predictions regarding four major stressors to the world's oceans over the next several decades. In their paper published in the journal Nature ...
Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet's surface. Yet, the ancient sun was about one-third less warm and climate modelers ...
