Big change on a big landscape

The Alsek, a world-class rafting river that flows into the Gulf of Alaska from its headwaters in Canada, may soon abandon the lower part of its drainage for a steeper one 15 miles away. The re-route will be due to the extreme melt of Grand Plateau Glacier, which acts like a cork that prevents the Alsek from following a faster path to the sea.

Discovery and wonder have characterized the last 100 years of science as we learned the plates shift, the climate changes, and scientists are studying the Moon, Mars, and beyond in detail. Our species now has a global view of how …

Smoke from wildfires has cooling effect on water temperatures

Smoke generated by wildfires can cool river and stream water temperatures by reducing solar radiation and cooling air temperatures, according to a new study in California’s Klamath River Basin. A new study published in Water Resources Research, a journal of the American Geophysical Union, suggests smoke-induced cooling has the potential to benefit aquatic species that require cool water to survive because high summer water temperatures are a major factor contributing to population declines, and wildfires are more likely to occur during the warmest and driest time of year.
