Blue-green algae causing health crisis Southwest Florida – “It is not alarmist to say that the people of Florida are being slowly poisoned by the water”

By Howard Simon 23 April 2019 (Miami Herald) – Hats off to Southwest Florida Congressman Francis Rooney for pressing the Centers for Disease Control and Prevention and other federal agencies to tell the public what it knows about the threat of toxic blue-green algae. Finally, a public official is focusing attention on our public-health crisis, […]

Decreasing snow cover causes increasing methane production in frozen lakes

25 January 2019 (Uppsala University) – New, unexpected consequences of climate change keep presenting themselves. A new study from Uppsala University and SLU shows that a decreased snow cover on frozen lakes in boreal forests may inhibit the activity of methane degrading bacteria beneath the ice, thereby causing an increased net production of methane, a […]

By Naaman Zhou24 January 2019 (The Guardian) – Temperature records have tumbled across South Australia, with the city of Adelaide experiencing its hottest day on record, as the second heatwave in as many weeks hit southern parts of Australia Adelaide hit 46.6C on Thursday afternoon, the hottest temperature recording in any Australian state capital city […]

The hottest 15 places in the world today are all in Australia as record heatwave rages on – Thousands of flying foxes dead – “One of the worst things is in the aftermath and you hear the mums calling out for their pups”

16 January 2019 (The Journal) – The top 15 hottest places in the world today are all in Australia as a severe heatwave continues to roast the southeast of the continent. The Australian Bureau of Meteorology said the past four days were among the country’s top 10 warmest on record, with temperatures nearing 50 degrees […]

Phosphorus pollution reaching dangerous levels worldwide, new study finds

WASHINGTON D.C., 25 January 2018 (AGU) – Man-made phosphorus pollution is reaching dangerously high levels in freshwater basins around the world, according to new research. A new study published in Water Resources Research, a journal of the American Geophysical Union, estimated the global amount of phosphorus from human activities that entered Earth’s freshwater bodies from […]

Ocean oxygen levels dropping as world warms – “The decline in ocean oxygen ranks among the most serious effects of human activities on the Earth’s environment”

4 January 2018 (Smithsonian Environmental Research Center) – In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside […]

Global warming has quadrupled ocean dead zones – “The decline in ocean oxygen ranks among the most serious effects of human activities on the Earth’s environment”

4 January 2018 (SERC) – In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside these zones as […]

Study reveals scale of “nitrate timebomb”

By Roger Harrabin 10 November 2017 (BBC News) – Huge quantities of nitrate chemicals from farm fertilisers are polluting the rocks beneath our feet, a study says.Researchers at the British Geological Survey say it could have severe global-scale consequences for rivers, water supplies, human health and the economy.They say the nitrate will be released from […]

Microbes dictate regime shifts causing anoxia in lakes and seas – “Hysteresis loops and tipping points are a common feature of oxic-anoxic transitions, causing rapid drops in oxygen levels that are not easily reversed”

6 October 2017 (UvA News) – Gradual environmental changes due to eutrophication and global warming can cause a rapid depletion of oxygen levels in lakes and coastal waters. A new study led by professors Jef Huisman and Gerard Muyzer of the University of Amsterdam (UvA) shows that microorganisms play a key role in these disastrous […]

Lake Erie algal bloom cleanup falling far short of 40 percent phosphorus reduction goal

By James F. McCarty 11 October 2017 (The Plain Dealer) – Approaching the end of another summer marked by a substantial algal bloom in Lake Erie’s western basin, environmental and conservation groups released separate reports Tuesday that came to the same conclusion: Ohio, Michigan and Ontario are falling far short in their efforts to reduce […]
