NASA scientists find new human-caused shifts in global water cycle

Greenbelt MD (SPX) Jan 17, 2025
In a recently published paper, NASA scientists use nearly 20 years of observations to show that the global water cycle is shifting in unprecedented ways. The majority of those shifts are driven by activities such as agriculture and could have impacts on ecosystems and water management, especially in certain regions.

Approximately 66 million years ago, a massive asteroid known as the Chicxulub impactor struck the Yucatan Peninsula in present-day Mexico. Measuring an estimated 10 to 15 kilometers in diameter, the asteroid left a colossal 200-kilometer-wide crater. This event triggered rapid climate changes that ultimately caused the extinction of non-avian dinosaurs and about 75% of Earth's species. A signifi

For decades, scientists have tried in vain to accurately predict solar flares - intense bursts of light on the Sun that can send a flurry of charged particles into the solar system. Now, using NASA's Solar Dynamics Observatory, one team has identified flickering loops in the solar atmosphere, or corona, that seem to signal when the Sun is about to unleash a large flare.
