The goby fish, both belonging to the genus Rhino ...
Farmlands are turning more saline due to climate change, rising sea levels, expanding drylands and groundwater depletion. This crisis is exacerbated by unsustainable farming practices. The resulting loss in crop yield threatens malnourished populations across the globe.
The continent of Africa has a distinctive physical geography—an "egg carton" pattern of basins and swells—that researchers attribute to plumes of mantle rocks rising beneath a tectonic plate.
2021 tied with 2018 as the sixth warmest year on a record that extends back to 1880, according to NASA's annual analysis of global average temperatures. The year contributed to an unprecedented, but well-understood trend in which the last eight years have been the warmest ever recorded.
Perennial water shortages in California will likely only grow worse due to climate change. But emerging technologies offer hope—if Californians can stop taking water for granted, says David Feldman, UCI professor of urban planning & public policy and director of Water UCI.
Repeated exposure to major disasters does not make people mentally stronger, a recent study from the Texas A&M University School of Public Health found that individuals who have been repeatedly exposed to major disasters show a reduction in mental health scores.
Giving up land to the sea needs to be one of the options considered for responding to serious erosion events along our coastline, says a University of the Sunshine Coast researcher.
"Hurricane Hunter" aircraft are mobilizing for an expanded 13-week period that began Jan. 5 to glean critical data for improving forecasts of atmospheric river storms over the Pacific Ocean. Such storms provide up to half of the U.S. West Coast's annual precipitation and a majority of the flooding.
When it comes to the business of seafood, COVID-19 hasn't been nearly as damaging as the ecological havoc caused by humans, a recent global survey of fish farms found.
Extreme natural phenomena have caused mass biodiversity extinction five times throughout the history of life on Earth. Many experts now believe that a Sixth Mass Extinction is underway, this time caused entirely by human activities.
Though there is a suggestion that large industrial farms can harm biodiversity, there are solutions farmers can put in place to mitigate this and promote wildlife growth in agricultural settings.
