"Lake Erie’s harmful algal blooms have started sooner and had longer peak periods over the past decade compared to earlier years, newly released data shows. Warming temperatures linked to climate change are a cause, according to researchers for NOAA’s National Centers for Coastal Ocean Science, with interactions among species likely playing a role as well.

"The NOAA scientists discussed the shift and forecast a moderate to above-moderate algal bloom for the lake’s western basin this summer during a briefing last month at Ohio State University and Ohio Sea Grant’s Stone Laboratory, off the coast of Put-in-Bay on Lake Erie.

"Algal blooms occur when #cyanobacteria, or blue-green algae, grow out of control due to a combination of excess #nutrients, #weather patterns and other #ecological factors. The blooms can be a serious public health problem because some types of cyanobacteria produce toxins. #Microcystin, for example, can lead to skin rashes, gut problems and liver and kidney issues. Relatively high levels of it in August 2014 prompted a two-day shutdown of #Toledo’s public #WaterSupply, which comes from Lake Erie."

Climate change is increasing risk of high toxin concentrations in northern US lakes, study finds

As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research led by Carnegie's Anna Michalak, Julian Merder, and Gang Zhao. Their findings, published in Nature Water, identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.

Current estimates of Lake Erie algae toxicity may miss the mark

There is more to a harmful algal bloom than the green stuff in water that meets the eye—specifically, a changing hazard level of toxins produced by the microbes that make up the scummy mess.

This CBC article notes the trade-off associated with #eutrophication and #AlgalBlooms with fish habitat use and productivity. Our collaborative 2019 project in #LakeErie targeted this exact factor. Many players with Fisheries and Oceans Canada (#DFO), Ohio State U and EPA among many others. Required the CCGS Limnos, EPA Lake Explorer II and DFO RV Cisco. A bunch of papers will be out this year for this project! #cyanobacteria #HABs #microcystin #Fisheries #GreatLakes

Some Lake Erie anglers consider algae blooms helpful — but what are the health implications? | CBC News

Despite often being described as smelly and not nice to look at, some anglers say they find algae blooms helpful when it comes to catching more fish in Lake Erie. Scientists weigh in on possible human and fish health impacts from algal blooms.
