We’ve heard a lot about lead service lines after the Flint water crisis. But that’s not the only way lead can get into your drinking water.

Birds breeding early to catch up to climate change

May 15, 2017

 


New research shows that in order for some early birds to catch the worm, they have to breed sooner in the spring.

 

Luke DeGroote is the avian research coordinator at Carnegie Museum of Natural History, and he runs the bird banding program at the museum's Powdermill Nature Reserve.

 

Right now, he’s in the thick of spring migration.

 

“It’s sort of a bit like fishing, in a way. We put out our nets to see what we catch,” he says.

 

The U.S. Geological Survey reports since the turn of the last century, water levels of Lake Michigan have increased in a series of even higher peaks. One was in 1964. An expensive house in St. Joseph was taken by the lake.

There was damage up and down Michigan’s coast. Another high lake water moment spanned from 1985 to 1987, and again there was a lot of damage to homes, beachfront property and industry.

The uncertain future of Great Lakes funding

May 11, 2017

Now that President Trump has signed the spending bill, Great Lakes funding is safe, at least for now.

The Great Lakes Restoration Initiative is funded in full for 2017. But Trump wants to eliminate this funding entirely in his 2018 budget proposal.

The past few days have seen unseasonable cold across much of Michigan, with temperatures falling below freezing in many parts of the state. A late freeze like this one threatens Michigan’s fruit crop at a crucial time in its annual cycle.

A fight is brewing over Great Lakes fish

May 4, 2017

The rules for commercial fishing in Michigan are being rewritten in Lansing. The law is old and needs to be updated. There are only 21 non-tribal businesses licensed by the state to catch fish for market. Tribes fish under their own rules.

Monarch butterflies need more to eat. That's the conclusion of a new study from the U.S. Geological Survey.

The only thing monarch butterfly caterpillars can eat is milkweed.

Wayne Thogmartin is a quantitative ecologist with the USGS. He says the butterfly population has dropped by about 80% since the mid-90s. The population has rebounded a little bit in the last three years, but Thogmartin says it's not a huge improvement.

One of the most famous and vocal climate scientists is speaking out, again. Penn State researcher and author Michael Mann was recently asked by Democrats to be a witness at a hearing on climate science. It was held by the House Committee on Science, Space and Technology.

Mann called the other three witnesses fringe experts because they were questioning the science behind climate change.

Three years ago today, the city of Flint switched to the Flint River for its drinking water. We all know how that story goes.

So now, three years later, how has what happened in Flint changed the way we look at our drinking water?

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.

The Montmorency tart cherry is pretty much the only sour cherry grown in the U.S. And cherry growers in Michigan know the tree really well. It was brought here from France a couple of hundred years ago. "This is older than most people think of as heirloom varieties and it's our main variety to this day," says Jim Nugent, a cherry grower in northern Michigan.

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 Next Idea

Everyone from author Michael Pollan to climate change experts have suggested raising cattle for beef is hard on the environment.

The amount of resources that go into producing a pound of beef are a lot greater than what it takes to produce a pound of chicken, for instance. Plus, in some cases, transporting beef further adds to its carbon footprint.

The changing climate the Earth is experiencing is changing the forests in Michigan. Warmer and shorter winters affect trees, pests and the diseases that damage trees.

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?

High winds have been punching Michigan squarely in the nose today.

“I was seeing the strongest winds I’ve ever seen in my 35 years as a meteorologist in Michigan today,” said Jeff Masters, a meteorologist with Weather Underground.

Gusts are knocking down power lines and trees across the state. Over 350,000 customers are without power.

 

It's an especially precarious time for Lake Erie's future.

In some parts of Michigan, there are forests that can take you back in time. Old-growth forests of towering trees offer a rare glimpse at what Michigan looked like before the logging boom of the late 1800's.

Donald Dickmann, a professor in Michigan State University's Department of Forestry, told Stateside where visitors can see stands of old-growth trees in Michigan.

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.

We know hunters who take deer or goose out of season are poachers. But what about those who take a plant from a park or a reserve without permission?

They too are poachers and plant poaching can be a huge, illegal business.

It's been nearly a year since the state of Michigan approved year-round and nighttime hunting for coyotes. But how effective has that change in hunting policy been, and how has it impacted the state's coyote population?

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.
