Snowfall on a major summit in North America’s highest mountain range has more than doubled since the beginning of the Industrial Age, according to a study from Dartmouth College, the University of Maine, and the University of New Hampshire.

In the Autumn leaves fall and apparently contaminate soil. It happens in the Italian woods where remediation is required by law for heavy hydrocarbon concentration greater than 50 milligrams per kilo.

It’s the kind of thing you might lose sleep over.

How will humans survive serious infections in the future if we’re running out of tools today to fight them? Antibiotic resistance among disease-causing bacteria is of global concern, as some last-resort drugs can no longer cure common illnesses such as urinary tract infections. 

Right now, a handful of motivated Fort Collins citizens are doing something a little out of the ordinary. They’re collecting cutting-edge scientific data from their backyards that may soon help NASA create maps of global air pollution.

Recent stories in the national media are magnifying fears of a catastrophic eruption of the Yellowstone volcanic area, but scientists remain uncertain about the likelihood of such an event. To better understand the region’s subsurface geology, University of Illinois geologists have rewound and played back a portion of its geologic history, finding that Yellowstone volcanism is far more complex and dynamic than previously thought.

Imagine a scenario where a volcano is about to erupt and you are responsible for deciding what to do next. Who should be alerted and who needs to be evacuated? Where and when might lava start flowing? How dangerous will the gas and ash emissions be?

This is what Earth Sciences 421 students experienced during a five-hour volcano simulation exercise in early December.

An imbalance between the trends in two common air pollutants is unexpectedly triggering the creation of a class of airborne organic compounds not usually found in the atmosphere over urban areas of North America, according to a new study from Caltech.

How would today’s weather patterns look in a warmer, wetter atmosphere – an expected shift portended by climate change?

Colorado State University researcher Kristen Rasmussen offers new insight into this question – specifically, how thunderstorms would be different in a warmer world.

Lakes suffering from harmful algal blooms may not respond to reduced, or even discontinued, artificial nitrogen loading.

Many blue-green algae responsible for algal blooms can fix atmospheric nitrogen dissolved in the water, and therefore water stewards should focus their efforts on removing phosphorus from lakes to combat algal blooms.

Old forests that contain large trees and a diversity of tree sizes and species may offer refuge to some types of birds facing threats in a warming climate, scientists have found.
