Maybe this is what it would be like to ski on Mars.

In late March 2018, the people of Eastern Europe and Russia found their snow cover had a distinctly orange tint. The color came from vast quantities of Saharan dust that was picked up by strong winds, lofted over the Mediterranean Sea, and deposited on Bulgaria, Romania, Moldova, Ukraine, and Russia. Skiers in the Caucasus Mountains snapped photos that looked like they could have come from the Red Planet.

Highly complex interactions among roots, fungi and bacteria underlie the ability of some trees to clean polluted land, according to a novel study by bioinformatics and plant-biology experts from McGill University and Université de Montréal.

In the wake of the recent water crisis in Flint, Michigan, in which studies confirmed lead contamination in the city’s drinking supply, awareness of the importance of protecting watersheds has increased. User-financed ecosystem service programs can compensate landowners to voluntarily participate in environmental improvement efforts. Now, researchers from the University of Missouri have found in a nationwide survey that members of the public are more willing to pay for improved water quality than other ecosystem services such as flood control or protecting wildlife habitats.

According to researchers at Aalto University, Finland, large-scale weather cycles, such as the one related to the El Niño phenomenon, affect two-thirds of the world’s cropland. In these so called climate oscillations, air pressure, sea level temperature or other similar factors fluctuate regularly in areas far apart in a way that causes rain and temperature patterns to shift significantly.

Fog harvesting may look like whimsical work.

After all, installing giant nets along hillsides and mountaintops to catch water out of thin air sounds more like folly than science. However, the practice has become an important avenue to clean water for many who live in arid and semi-arid climates around the world.
