Over the past 20 years, Great Lakes water levels have gone from sustained multiyear lows to multiyear highs. Climate change is accelerating the transition between dry phases and wet phases.
In many municipalities, aging water infrastructure is serving fewer people than it was built to accommodate. Out of sight has meant out of mind – but resulting changes in water quality may affect safety.
Lead contamination is not just a problem for Flint, Michigan. It is an issue in many regions. One epidemiologist figured out how to measure past lead exposure using treasured biological samples.
The source of water on Earth, the Moon and planets in our solar system is hotly debated. Some in the planetary science community argued that it came from asteroids and comets. Now they have proof.
Hydrogen is the first element in the periodic table and essential for life on Earth. It may also be key to shifting away from fossil fuels toward clean sources of energy, but challenges remain.
Satellites hundreds of miles overheard are helping scientists to predict drought, track floods and see how climate change is changing access to water resources.
