Scientists have uncovered strong evidence that a major Atlantic Ocean current system tied to global climate is weakening. The slowdown has been detected across a vast region of the North Atlantic over ...

Even below the 1.5-degree Celsius threshold, California reservoirs no longer fill in some years and overflow with extreme ...

Ocean temperatures may be quietly protecting the world from a global drought catastrophe. By analyzing more than a century of climate data, researchers discovered that droughts rarely spread across ...

The Earth’s climate system is now “out of balance,” according to a new global report — with scientists warning that a key measure of warming has reached its highest level on record. The latest “State ...
