The 51-square kilometer (20-square-mile) pileup is an important yet poorly quantified part of the carbon cycle, scientists say.

Streamflow is increasing in Alaskan rivers during both spring and fall seasons, primarily due to increasing air temperatures over the past 60 years, according to new CU Boulder-led research.

On the slender wings of the tiny Pipistrel Velis Electro ride some of the greatest the hopes of the aviation industry — and the Waterloo Institute for Sustainable Aeronautics (WISA). 

March was a turbulent month weather-wise across the United States, as a series of western storms brought record amounts of precipitation and tornadoes ripped through parts of the South and the nation’s midsection. 

Research shows flooding events in the province have doubled in the last century.

The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, depending on their unique temperature, light and flow.

Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists.

Reducing global carbon dioxide emissions is critical to avoiding a climate disaster, but current carbon removal methods are proving to be inadequate and costly.
