Ice-free Arctic summers now very likely even with climate action

The loss of summer sea ice in the Arctic is now very likely before 2050, new research shows, even if the carbon emissions driving the climate crisis are cut rapidly. The result has alarmed scientists but they said slashing greenhouse gases remained vital as this would determine whether Arctic summer ice vanished permanently or could

Environmental Cleanup Courtesy of a NASA Cafeteria Brainstorm

Jackie Quinn had an idea. What if the system NASA developed for removing contaminants from building paint could also be used to clean up the environment? In her quest to find out, the engineer demonstrated NASA resourcefulness, starting out with a couple of plastic drinking straws she grabbed from a cafeteria at the agency’s Kennedy

Arctic stratospheric ozone levels hit record low in March

Ozone levels above the Arctic reached a record low for March, NASA researchers report. An analysis of satellite observations show that ozone levels reached their lowest point on March 12 at 205 Dobson units. While such low levels are rare, they are not unprecedented. Similar low ozone levels occurred in the upper atmosphere, or stratosphere,

Climate change: US megadrought ‘already under way’

A drought, equal to the worst to have hit the western US in recorded history, is already under way, say scientists. Researchers say the megadrought is a naturally occurring event that started in the year 2000 and is still ongoing. Climate change, though, is having a major impact with rising temperatures making the drought more

How silver ions kill bacteria

The antimicrobial properties of silver have been known for centuries. While it is still a mystery as to exactly how silver kills bacteria, University of Arkansas researchers have taken a step toward better understanding the process by looking at dynamics of proteins in live bacteria at the molecular level. Traditionally, the antimicrobial effects of silver

The link between virus, wildlife and the environment

As COVID-19 spreads across the globe, a common question is, can infectious diseases be connected to environmental change? Yes, indicates a study published today from the University of California, Davis' One Health Institute. Exploitation of wildlife by humans through hunting, trade, habitat degradation and urbanization facilitates close contact between wildlife and humans, which increases the

Climate change to affect fish sizes and complex food webs

Global climate change will affect fish sizes in unpredictable ways and, consequently, impact complex food webs in our oceans, a new IMAS-led study has shown. Led by IMAS and Centre for Marine Socioecology scientist Dr Asta Audzijonyte and published in the journal Nature Ecology and Evolution, the study analysed three decades of data from 30,000

Heat stress may affect more than 1.2 billion people annually by 2100

Heat stress from extreme heat and humidity will annually affect areas now home to 1.2 billion people by 2100, assuming current greenhouse gas emissions, according to a Rutgers study. That's more than four times the number of people affected today, and more than 12 times the number who would have been affected without industrial era
