A lot of different chemicals end up in our rivers and streams.

Researchers are finding these mixtures of chemicals are more complex than we thought, and it could hurt fish and other creatures.

This year’s Winter Study of the wolves and moose of Isle Royale found that there are still just two wolves hanging out on the island.

Tomorrow evening at 7pm, the Michigan Department of Environmental Quality is holding a public hearing on a request from Nestle Waters. 

Fish consumption advisories usually focus on one chemical at a time – like mercury – and these advisories tell you how much of each kind of fish you should eat, and what to avoid. But they don’t often tell you much about mixtures of different chemicals in the environment that could be in fish.

Most of us don't think about how much electricity costs at different times of the day. But the state's two largest utilities are planning to change that.

When it's really, really hot and humid out, what do lots of people do when they get home? They turn on, or turn up, the air conditioning.

There are big spikes in electricity demand on the hottest summer days, between 2:00 in the afternoon to 7:00 in the evening.

The buildup of nutrients in western Lake Erie can trigger algae growth – and contaminate drinking water in nearby cities. That happened as recently as 2014, when Toledo residents could not drink their water for two days.

Here’s one way to react to a warming planet: get smaller.

We know mammals literally shrank, during a massive global warming event 56 million years ago. Imagine an early horse ancestor the size of a cat.

Now back then, the earth was 46 degrees hotter on average than it is right now.

So researchers wanted to know: do mammals still experience shrinking - a.k.a. dwarfing - during other, less intense periods of warming?

Funding for Great Lakes protection at risk?

Mar 7, 2017

Early budget indications suggest the Trump administration could slash funding for the Great Lakes.

There are many possible cuts to EPA programs. Great Lakes restoration money could be cut by 97%, and money for beach monitoring could be also at risk.

President Trump called for a trillion dollar investment in infrastructure this week in his address to Congress.

The Great Lakes Commission has ideas for where some of the money should go. The Commission is an interstate compact agency that represents Great Lakes states. The agency released recommendations today for rebuilding our water infrastructure.

These maps show the early arrival of spring

Feb 28, 2017

Scientists have known that spring is arriving earlier across the U.S. because of climate change. Now, you can take a look at new maps from the U.S. Geological Survey to see how early spring is arriving where you live.

Jake Weltzin is an ecologist with the USGS, and the executive director of the National Phenology Network.

"The folks down in the southeastern United States, across much of that region, are seeing spring coming as many as three weeks early this year," he says.

Energy costs can be a huge burden on low-income communities.

That’s especially true in Highland Park. The tiny enclave within Detroit was literally left in the dark after it ran up a big street lighting bill.

But there are some small bright spots popping up—thanks to solar power, and the efforts of one community group.

The International Joint Commission, a treaty organization that advises the United States and Canada, says the two countries should do more to keep microplastics out of the lakes.

Microplastics are tiny pieces of plastic that are five millimeters or smaller. Microbeads are used in things like soap and toothpaste. Microfibers are tiny fibers that wash off our synthetic clothing, like fleece.

Those tiny plastics can end up in the Great Lakes and can get into fish.

Shortly after the election, researchers from the U.S. and Canada got together to start backing up scientific data from federal agencies in the U.S.

They’re also keeping a close eye on how the Trump Administration is changing federal websites, and they're already finding some changes.

One of the groups heading up this effort is called the Environmental Data and Governance Initiative. (You can see EDGI's report on changes to some EPA websites here, and its report on the State Department and Department of Energy here.)

There’s been a lot going on at the Environmental Protection Agency lately.

First, the Trump administration barred anyone at the EPA from communicating with the public. Then, a White House official announced that EPA research could be subject to review by the administration.

The Trump administration has sent strong signals that it’s going to be friendly to industry.

Will grass carp spread in the Great Lakes?

Jan 31, 2017

There are grass carp in three of the Great Lakes, but it’s not too late to do something about it.

That’s one of the conclusions of a new risk assessment on this type of Asian carp by the United States and Canada.

"Goldilocks days" and a warming climate

Jan 25, 2017

2016 was the hottest year on record.

When we talk about climate change, we usually talk about extreme weather events: extreme heat, drought, flooding. But scientists have also studied what’s likely to happen with the best weather days. Days that are not too hot, not too cold, or humid or rainy. Just right.

Researchers have found a chemical that’s widely used on crops such as almonds, wine grapes and tree fruits can be bad for bees.

They’ve found it makes honey bee larvae more susceptible to deadly viruses.

Bumble bee added to the endangered species list

Jan 12, 2017

For the first time in the U.S., a bumble bee has been listed as an endangered species. 

It’s called the rusty patched bumble bee. The species is no longer found in Michigan, but small populations still exist elsewhere in the Great Lakes region.

State officials want you to check your trees for a tiny insect. It’s called the hemlock woolly adelgid, and it survives by sucking sap from hemlock trees.

This insect was first detected in Michigan in 2006.

The U.S. EPA estimates that companies in Michigan waste up to a third of the energy they buy because of inefficient buildings and equipment.

But most of the companies just keep paying those high energy bills, month after month, because they can't make a business case for a big energy efficiency project. The payback for the upgrades takes too long – often ten or more years.

The winter study of the wolves and moose on Isle Royale is heading into its 59th year. The wolf-moose study is the longest running study of any predator and its prey in the world.

Scientists from Michigan Tech spend several weeks on the island in the middle of winter every year. They'll be heading back out soon.

Last month, we heard how an abundance of deer is reshaping the forests in northern Michigan. Deer are eliminating trees like maple, oak and cedar in many places.

The trees can’t reproduce because any seedling that sprouts up is eaten.

Today, we visit a forest in Leelanau County where a conservation group has taken an unusual step to address the problem.

Federal agency changes rules on accidental eagle deaths

Dec 20, 2016

Bald eagles came off the endangered species list in 2007 because they were doing so well. These days you can see more bald eagles than in any time in the past 50 years, according to the U.S. Fish and Wildlife Service.

The agency has just finalized a new rule about bald and golden eagles, which revises the permitting system for unintentional impacts on eagles.

A year ago, Flint Mayor Karen Weaver declared a state of emergency in the city. Now, officials say the water is improving, but it’s still not safe to drink without a filter.

The water crisis has forced some people to make tough choices.

Dana Banks and her husband Charles were both born and raised in Flint, and they still have a lot of family here. Their church is here. Their house, right near downtown, is the first home they bought together.
