What you need to know, currently.

NOAA is predicting a less damaging algal bloom for Lake Erie this year. It’s expected to start in mid-July and to measure only 3.5 on the severity index — last year’s bloom was a 6.

“Toxic algae affect not only the health of people and marine ecosystems, but also the health and vibrancy of local and regional economies,” said Nicole LeBoeuf, Assistant Administrator for NOAA’s National Ocean Service.

The forecast is part of NOAA’s Ecological Forecasting Service, which predicts ecological conditions that are often tied to, and exacerbated by, climate change and the weather.

Many scientists believe Harmful Algae Blooms (or HABS) are worsened by climate change, although a 2021 paper in Nature found the situation was slightly more complex. HABS may seem to be increasing because of more intense oversight, but their effects aren’t being felt equally across the globe. HABS were found to be increasing in Central and South America, but decreasing in Australia and New Zealand.

Study co-author Henrik Envoldsen explained that because of the emerging aquaculture industry and increased monitoring due to climate change, we’re noticing more about the world.

“Some [HABs] are more related to the fact that we are everywhere,” Envoldsen told Mongabay. “And then we encounter what has always been there as a part of a natural ecosystem.”
