Scientists in the UCAR community found themselves on the front lines of the cyber revolution that stormed the world in the 1990s. Many UCAR universities were early adopters of the World Wide Web, a technology well suited to a science that thrives on distributed data and collaboration.

Intrigued by an atmospheric mystery bringing down aircraft, a small group of scientists at NCAR embarked on a series of field studies from the late 1970s through the 1980s.

Rarely before the 1980s did a scientific issue jump from the corridors of research to the halls of international diplomacy in less than a decade. Such was the case when a profound threat to the Antarctic’s protective layer of stratospheric ozone became apparent.

The biggest swarm of tornadoes ever recorded—148 in all—rumbled across the U.S. Midwest and South on 3–4 April 1974.

The periodic cooling of the eastern tropical Pacific Ocean helps bring rain to Alaska and blizzards to Colorado.
