More than 15,000 plant species have a high probability of being considered threatened or near-threatened under a new model used to predict conservation status.

Once spring-run chinook salmon disappear, they are not likely to reemerge, indicates genetic analysis of the revered wild fish in a study led by the University of California, Davis. Prompt conservation action could preserve spring-run chinook, as well as their evolutionary potential.

Writing in Scientific Reports, researchers say effective management of the marine environment could mitigate the impact of future global changes.

Global emissions are on the rise as national commitments to combat climate change come up short. 

A new federal report finds that climate change is affecting the natural environment, agriculture, energy production and use, land and water resources, transportation, and human health and welfare across the U.S. and its territories.

In a time when fake news, bots and pseudoscience make it challenging for individuals to separate fact from fiction, Werklund School of Education graduate student Lauryn Record is exploring the increasing significance of the non-formal science education taking place at museums, science centres, zoos and aquariums.

Today many regions rely on ever more sophisticated irrigation systems, using pumps and water sensors to grow crops on otherwise unworkable land as efficiently as possible. But not every part of the world benefits from modern irrigation and lack of freshwater is often the major limiting factor in crop production. Now a study reveals that global irrigation levels could sustainably increase by nearly 50%, boosting crop yields and feeding an additional 2.8 billion people.

The U.S. Environmental Protection Agency (EPA) released its final state implementation plan (SIP) Requirements Rule for implementing the 2015 National Ambient Air Quality Standard (NAAQS) for ground-level ozone. These requirements apply to states and tribes with nonattainment areas as well as the 13 northeastern states that currently comprise the Ozone Transport Region. This rule will assist our state and tribal partners in developing their implementation plans to meet the 2015 ozone standards, while providing the greatest flexibility possible.

When the phone rang at 5 a.m., Graham Tapley felt the bottom of his stomach drop.

Urban planning decisions from decades past are likely a contributing factor to the rise of right-wing populism, a study from the University of Waterloo has found.
