We talk a lot about how people can adapt to climate change, and scientists have found that some animals are changing their behavior, too. The ability to change rapidly because of environmental changes is called behavioral flexibility.

Remember how it was too hot for planes to fly in Phoenix last month?

That could happen more often as our climate warms.

Radley Horton is an associate research professor at Columbia University’s Lamont-Doherty Earth Observatory. Horton is an author of a new study on this issue in the journal Climatic Change.

This past June, President Trump fulfilled a campaign promise when he announced that the United States would withdraw from the 2015 Paris climate accord, and end the implementation of carbon reduction targets set under the Obama administration. What are the implications of this decision on climate policy in the United States? And can local governments and the private sector fill in the void left by the federal government?

Biologists say the sixth mass extinction episode on Earth is already happening. But researchers say if we only look at species extinctions, we miss a big part of the story.

Paul Ehrlich is a professor emeritus of biology at Stanford University, and an author of a new study about this published in Proceedings of the National Academy of Sciences.

23 counties in Michigan have reported one or more unhealthy ozone days each year, on average. That’s from a new analysis by the Natural Resources Defense Council.

An online map the group produced also shows where those high ozone days tend to overlap with high pollen days. That can make air unhealthy for people with respiratory problems.

Most of us expect to hear that trees are moving north in search of colder temperatures because of global climate change. But trees don’t only need colder temperatures; they also need to have enough water.

A new study published in Science Advances suggests that trees are moving west in search of more moisture.

Associate Professor School for Environment and Sustainability Inés Ibáñez joined us on Stateside to share her perspective on the many other global change factors that are causing this migration.

A majority of Americans believe states should take the lead to address climate change if the federal government fails to act.

That’s one of the findings of the latest in a series of National Surveys on Energy and Environment.

What do tiny pieces of decomposing leaves have to do with climate change? It turns out they’re nitrous oxide hot spots.

Nitrous oxide is a greenhouse gas that’s 300 times more potent than carbon dioxide.

Less than eight months after General Motors made its initial 100% renewable energy commitment, the Detroit automaker's CEO, Mary Barra, says the timeline will be sped up.

"That's a stake that we put in the ground and now we plan to move that back," Barra said at a press conference held prior to GM's annual shareholders meeting.

A spokesman for GM confirmed the plan, but says there is "no new timetable to announce at this point."

President Donald Trump announced the United States would be withdrawing from the Paris Climate Accord. The agreement calls on participating countries to make efforts to limit global temperature rise.

The United States joins Syria and Nicaragua as the only countries who did not sign on to the accord.

In the wake of President Trump leaving the Paris Climate Agreement, several dozen mayors across the U.S. have created a coalition to uphold the goals of the accord in their own cities. Ann Arbor, Grand Rapids, and Traverse City represent Michigan on the list.

DTE Energy will close its last coal-burning plant by 2040, and reduce its carbon emissions by 80% by 2050, compared to 2005 levels.

The decision comes in spite of the Trump administration's decision to slam the brakes on the Clean Power Plan, which would have allowed the U.S. EPA to regulate carbon emissions for the first time.

While the president and top administration officials continue denying the causal connection between carbon emissions from human activity and climate change, many corporations, including utilities like DTE, have accepted it as fact.

Several hundred people from Michigan got on buses today to ride all night to Washington, D.C., to attend the 2017 People's Climate March.

Andrew Sarpolis with the Sierra Club organized the bus leaving from Detroit. He says many of the buses sold out early.

"Flint filled up almost a month ago," he says. "Our bus filled up a week in advance, and I believe the Ann Arbor bus as well, so all across the board, we're really seeing a lot of interest in going to this march."

Any time there’s a heat wave, or a drought or a big flood, scientists like Noah Diffenbaugh get a lot of calls.

“We are as scientists being asked whether or not global warming has played a role in individual extreme weather events,” he says.

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.

Some government websites are changing what they say about the environment, and a group of researchers is keeping track. Researchers in the U.S. and Canada are continuing to back up scientific data from federal agencies in the U.S.

They’re also keeping a close eye on how information is changing on federal websites like the EPA, the State Department and the Department of Energy, along with other federal agency sites, and they've been finding changes are happening.

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.

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?

You know how in old Disney cartoons and movies, spring arrives and all the birds and woodland creatures just wake up all at once?

That’s kind of how nature works, too.

But new research suggests that what we typically think of as spring: flowers blooming, ice melting... is starting to change.

For the last couple days, I, together with a million or so of my fellow Michiganders, have been living a sort of 19th century life.

By that I mean that we’ve been living without power, electricity or heat, thanks to the freak windstorms that whipped through much of our state.

Now, we’re not quite in the same boat as Abraham Lincoln. He didn’t have Double-A batteries, nor could he go to a motel with internet access, which is how I am broadcasting today.

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.

It’s supposed to be warm throughout the state of Michigan this weekend. Really warm: highs may breach 60 in the southeast corner of the state, while up in the U.P. temperatures could be in the low 50s.

If you’re looking for a good way to get outdoors and take advantage of our temporarily tropical climate, the state’s Department of Natural Resources has an idea for you:

The summer blast happens to coincide with the state’s winter free fishing weekend, during which angling on Michigan’s lakes, rivers and streams requires no fishing license.

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.)

According to NASA, 2016 was the warmest year since record-keeping began in 1880. It was the third straight year to break the record for global average temperatures.

Around the world, governments, businesses and individuals are taking steps to reverse this trend. 

Most of these efforts to combat climate change have centered on reducing emissions of carbon dioxide (CO2) into the air, largely by limiting the use of fossil fuels. But what if simply reducing carbon emissions—even reducing them to zero—is not enough? That is the assumption behind a new initiative from the University of Michigan.

We know a lot about how important wetlands are for filtering water, and controlling floods. A new study documents another big benefit wetlands give us: storing carbon.

Siobhan Fennessy is a biology professor at Kenyon College in Ohio. She says wetlands act like a buffer for climate change.

“Wetlands are really seen now as an ecosystem that can offer us resilience in the face of a changing climate because of their ability to take up carbon dioxide from the atmosphere," she says.

Ann Arbor is joining a "guerrilla archiving" movement.

Librarians, web developers and other volunteers are working fast to save scientific data from federal agency websites.

It’s called Ann Arbor Data Rescue, and it’s part of a larger project that’s springing up around the U.S. and Canada.

They’re doing this in case the Trump Administration changes or removes data.

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.

There have been five mass extinction events on planet Earth over the past 540 million years. Among these are the asteroid strike that is thought to have killed off the dinosaurs roughly 65 million years ago, and four less infamous extinctions, such as the “Permian event” that occurred 250 million years ago.

During these periods, at least three-quarters of all species on earth went extinct. The dinosaurs vanished, as did the giant insects of the Permian era.

Biologists now suggest that a sixth extinction is underway.

The sub-zero temperatures across the state of Michigan this morning do not mean that global warming isn't real. 

Jeff Masters, Director of Meteorology for Weather Underground, is explaining this a lot these days.  He says the long-term trend is clearly a warming planet.  But global warming doesn't mean 'no more winter.'

"The earth is still tilted on its axis," says Masters, "which means we get unequal heating of the poles, and that causes the seasons, and the seasons haven't gone away.  We still expect cold weather, just less of it."

Word came down recently that Shell — the second-largest oil company in the world — has announced that it will link top executive bonuses to progress being made on managing greenhouse gas emissions.

In other words, if they don’t hit targets for reducing greenhouse gas emissions, they’ll get hit in the wallet.

It’s yet another example of business — in this case, a mammoth oil company — recognizing that its long-term survival depends on its ability to reduce the environmental impact of what it’s producing.
