The glowing algae is suffocating sea life.

Much goes to indicate that such toxins may cause damages to children’s central nervous system. Scientists in Tromsø, Norway have long worked to map the extent of environmental toxins in the Arctic populations, and the result is frightening.

Debris on Cocos (Keeling) Islands was mostly bottles, cutlery, bags and straws, but also included 977,000 shoes, study says

Watch where you step.

I knew that those Japanese currents would come to our waters, and so that’s why I volunteered to do the testing,” Eddie Ungott, a resident of Gambell.

Since 2014 St. Lawrence Islanders have been collecting sea water samples, knowing that the radiation would eventually show up. Now the signature of Fukushima has finally been identified, the northern most sample evidence of the plume. Fortunately the levels are low.

President Moon hopes collaboration with China will improve air quality in the country.

Alex Weber discovered more than 50,000 balls in the ocean near coastal California golf courses. When golf balls degrade, as these were doing, they release plastic particles and toxic chemicals.

The California overwintering population has been reduced to less than 0.5% of its historical size, and has declined by 86% compared to 2017.

Western Lake Erie's annual summer algal blooms are triggered, at least in part, by cyanobacteria cells that survive the winter in lake-bottom sediments, then emerge in the spring to "seed" the next year's bloom, according to a research team led by University of Michigan scientists.

Bacteria living more than 4,000 meters (2 miles) below the surface of the Pacific Ocean are absorbing an estimated 10 percent of the carbon dioxide that oc

Leptospirosis infections, caused by Leptospira bacteria, occur in people and animals around the world, but different strains of the bacteria may vary in their ability to cause disease and to jump between species. Now, researchers have for the first time described the characteristics of the Leptospira variants that infect cattle in Uruguay.

Zarantonelli et al. 2018. Isolation of pathogenic Leptospira strains from naturally infected cattle in Uruguay reveals high serovar diversity, and uncovers a relevant risk for human leptospirosis. PLOS Neglected Tropical Diseases 12 (9): e0006694 DOI: 10.1371/journal.pntd.0006694

EUMETSAT satellite shows blue-green algae bloom covering Lake Okeechobee.

From floods to fires, drought to coastal erosion, climate change is already having an impact on Canada's communities, landscapes and wildlife

An increase in carbon emissions are showing up not only in the air, but also in water. Now researchers and shellfish farmers are teaming up to see how marine plants can help stave off the effects of ocean acidification. Special correspondent Jes Burns of Oregon Public Broadcasting reports.

Fairbanks International Airport and Eielson Air Force Base no longer use a type of firefighting foam containing a chemical compound that’s contaminated groundwater around the city, and that poses a potential threat to human health.

The initial results represent 330 participants from six communities. Around 98 per cent of participants had mercury levels below the health guidance value - a baseline to assess health risks.

When the European Space Agency (ESA) launched a satellite into orbit on Oct. 13, it did so despite opposition from Inuit leaders in Canada and Greenland over its potential to contaminate an important Arctic area.

Trace 134Cs in northern fur seal tissue suggests that the population under study had been minimally exposed Fukushima-derived radionuclides. Despite this inference, the radionuclide quantities detected are small and no impact is expected as a result of the measured radiation exposure, either in northern fur seal or human populations consuming this species.
