Because of anthropogenic emissions of oxides of nitrogen (NOx), the NOx deposition rate is about five-fold greater than that of pre-industrial times largely due to energy production and biomass burning.

New research shows that this type of wildfire—which can survive the winter to re-emerge in spring—is becoming more common in high northern latitudes as the climate warms.

Heat from the Atlantic Ocean carried to higher latitudes is causing the edge of the sea ice to retreat.

Yellowstone National Park is famous for harsh winters but a new study shows summers are also getting harsher, with August 2016 ranking as one of the hottest summers in the last 1,250 years.

A large-scale research project at the University of Alaska Fairbanks Geophysical Institute has revealed insight into the relationship between surface debris on glaciers and the rate at which they melt.

Researchers have detected groundwater beneath a glacier in Greenland for the first time using airborne radar data. 

The frequency and intensity of heat waves in cities is increasing due to climate change, with a great negative impact on the health and mortality rates of the population.

Five years after the disastrous wildfire in Fort McMurray, Alta., researchers are warning that the complex role of peatlands, a factor critical to projecting the risk and behaviour of future fires, is missing from the forecasting model.

NOAA’s Climate Prediction Center is predicting another above-normal Atlantic hurricane season.

The dynamics that lift smoke from large wildfires into the upper atmosphere could potentially be employed one day to help temporarily cool the planet, based on the findings of a modeling study led by NOAA scientists.
