Arctic sea ice 6th lowest on record; Antarctic sees record low growth
Arctic sea ice likely reached its annual minimum extent on Sept. 19, 2023, making it the sixth-lowest year in the satellite record, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC).
Previously Overlooked Algae Toxin Widespread in Southern Indian River Lagoon
Pseudo-nitzschia spp., an algae that produces the neurotoxin domoic acid, can bioaccumulate within food webs causing harm to humans and animals. A molecular study of Florida’s Indian River Lagoon shows this algae was present in 87 percent of the water samples collected. All isolates showed toxicity, and domoic acid was found in 47 percent of surface water samples. As a nursery for many organisms that supports a high amount of biodiversity, the presence of domoic acid could negatively impact the lagoon system.
Expert available to discuss new report that puts globe on course for breaching benchmark high temperature
A new report from the World Meteorological Organization (WMO) shows that the world’s average temperature could breach a record 1.5 Celsius of warming compared to pre-Industrial Revolution levels. News reports call the WMO announcement a critical warning of an average world temperature limit in the face of climate. Researchers indicate the threshold could be broken as early as 2027.
Colorful films could help buildings, cars keep their cool
Air conditioners require a lot of energy and can leak greenhouse gases. Today, scientists report an eco-friendly alternative — a plant-based cooling film with many textures and iridescent colors that could someday keep buildings and cars cool. They will present their results at ACS Spring 2023.
Forest growing season in eastern U.S. has increased by a month
The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.
Horticulture expert addresses plant resiliency as seasons change
A West Virginia University expert is offering insights on the effects lingering winter weather and fluctuating temperatures could have on trees, shrubs and flowers heading into the official start of spring on Monday, March 20. Mira Danilovich, associate professor with…
Hummingbirds use torpor in varying ways to survive cold temps
Hummingbirds have the fastest metabolism of any animal. The tropical hummingbirds that live in the Andes Mountains in South America must expend considerable energy to maintain their high body temperatures in cold environments. One tool that they use to survive cold nights is called torpor, a hibernation-like state that allows them to ramp down energy consumption to well below what they normally use during the day.
Magnetic spins that ‘freeze’ when heated: Nature in the wrong direction
Physicists observed a strange new type of behaviour in a magnetic material when it’s heated up. The magnetic spins ‘freeze’ into a static pattern when the temperature rises, a phenomenon that normally occurs when the temperature decreases. They publish their findings in Nature Physics on July 4th.
Coldest Northern Hemisphere temperature, first recorded by UW–Madison, officially confirmed
Nearly 30 years after recording a temperature of minus 93.2 degrees Fahrenheit (minus 69.6 Celsius) in Greenland, the measurement has been verified by the World Meteorological Organization as the coldest recorded temperature in the Northern Hemisphere. The measurement was first recorded by a University of Wisconsin–Madison Antarctic Meteorological Research Center Automatic Weather Station in December 1991.

New Portable Tool Analyzes Microbes in the Environment
Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms – too tiny to be seen by the naked eye – and their response to threats to their ecosystems. Rutgers researchers have created just such a tool, a portable device that could be used to assess microbes, screen for antibiotic-resistant bacteria and analyze algae that live in coral reefs. Their work is published in the journal Scientific Reports.
