Scientists have been worried about the herring population in Lake Superior recently. In fact, last year they warned it might collapse.

Lake Superior is the only one of the Great Lakes with a large population of this native fish.

This fall, new rules protecting herring took effect in Wisconsin and Minnesota and things appear more stable.

But there may still be a big problem lying beneath the surface.

This year is likely to be the hottest on record. Scientists with the World Meteorological Organization announced that recently, as world leaders met in Morocco to talk about limiting the impacts of climate change.

President-elect Donald Trump has called climate change a hoax, and he’s said he’ll withdraw from the Paris climate agreement.

Andy Hoffman is a professor with the Ross School of Business and education director for the Graham Sustainability Institute at the University of Michigan.

He says we don’t really know what the president-elect’s climate policy will look like.

2016 has been on a record-breaking warm streak, according to the National Oceanic and Atmospheric Administration. 

So what does this unseasonably warm fall mean for birds that need to start packing up and heading south?

Andrew Farnsworth is a research associate with the Cornell Lab of Ornithology, and he runs BirdCast – it’s a tool the lab created to forecast what’s happening with bird migration each week.

Every day, you and I burn up all kinds of things.

We burn gasoline to get to work, mow the lawn, or fly to a conference. We burn natural gas, coal, or heating oil to heat our homes. And we burn up coal or natural gas when flipping on that light switch.   

Whenever we burn stuff, we release carbon dioxide into the atmosphere.

Burned a gallon of gas driving around town? You just put around 20 pounds of CO2 into the air.

That CO2 traps heat, and all the burning we do is causing the planet to warm dramatically.

Researcher Markus Hagemann says even he was surprised by the radical degree of change that will be required in energy use in order to limit global warming to a 2 degree Celsius increase.

Hagemann is with NewClimate Institute, a partner with Climate Action Tracker.

The group's research shows that gas and diesel-burning cars and trucks would have to get about 100 miles to the gallon by 2030, and the entire fleet will need to be at least 50% electric by 2050.

Do teachers' beliefs on climate change affect their students? Yes and no.

The vast majority of climate scientists agree climate change is happening and it’s mainly caused by people.

A new study looks at how middle school students' beliefs about climate change are shaped by their teachers’ own beliefs.

Our cities are especially vulnerable to climate change. More than 80% of people in the U.S. live in cities, so things like flooding and heat waves can affect a lot of people at once.

But city planners don’t always have a good handle on the risks their cities face.

The natural gas industry tells us that using natural gas is environmentally friendly. The industry says natural gas has fewer impurities than coal, and tells us its combustion yields mostly carbon dioxide and water vapor, so there’s less pollution.

But the main ingredient of natural gas is methane. And methane is one of the biggest contributors to climate change.

That’s why University of Michigan public policy assistant professor Catherine Hausman said we need to be concerned about what happens to the environment when methane leaks.

She also believes the utilities have little incentive to plug natural gas leaks. She recently wrote about the issue in an article at TheConversation.com and she joined Stateside to talk more about it.

Major stretches of highway throughout Metro Detroit were flooded out Tuesday morning, after heavy rainfall Monday night.

That’s likely a “new normal” people will just have to deal with going forward.

The first six months of this year were the warmest on record. This week, we heard about a deadly anthrax outbreak in Russia that's thought to be the result of permafrost thawing.

A new survey finds that fewer Americans doubt that climate change is happening, but it continues to be a highly polarizing issue.

Now, you can type in your zip code and see the future.

At least, you can see how hot it’s probably going to be.

The National Oceanic and Atmospheric Administration has updated the tool it calls Climate Explorer. It’s an interactive website loaded with data for each county in the U.S.

David Herring is with NOAA’s Climate Program office. He says you can type in your city or zip code, and see projections: for example, how many days might be hotter than 95 degrees Fahrenheit.

The Next Idea

Climate change presents one of the biggest problems we have ever faced. It is literally as large as our planet. We must take action to address it or its consequences will intensify, growing more costly and increasingly affecting us all.

Fortunately, we know what to do -- transition to cleaner sources of energy to reduce our dependence on fossil fuels. Quickly.

In the electricity sector, this means rapidly tapping into renewable energy resources like wind and solar on a grand scale.

New research finds people often stay quiet when it comes to talking about climate change.

It’s not because they’re afraid of being disliked.

A study published in the Journal of Environmental Psychology found that people avoid bringing up the subject for two main reasons:

1) People underestimate how much other people care about the subject.

2) People feel like they don’t know enough about the science of climate change to hold a discussion.

Climate activists see bringing climate change into the classroom as a simple matter of updating the science curriculum. But a recent survey revealed that science teachers are often ill-equipped to deal with the subject.

A survey published in the journal Science earlier this year showed that most science teachers spend little time teaching climate change - just an hour or two a year.

 

But making climate change a classroom priority doesn’t always win you fans.

University of Michigan researchers are trying to figure out what exactly it takes to get people to care about climate change. Their study is published in Nature Climate Change

What they found seems to refute the popular line of thinking that culture is the biggest factor in whether we care and are willing to do something about climate change.

City officials around the country are trying to figure out how to make changes in their communities to adapt to climate change.

Researchers from the University of Michigan and the University of North Carolina looked at 44 of these climate adaptation plans, and found they were a mixed bag.

Michigan will see more extreme storms as the climate changes

By 2095, Michigan's summers will be like those we're used to seeing in Arkansas and Mississippi. Our winters will be like West Virginia's and Kentucky's.

And that changing climate – with extreme heat, big storms, plus a LOT more rain and snow – means we're looking at five major health risks, according to a new report from climate researchers and the state health department.

Some kinds of birds are doing better in our changing climate, and others are declining. These changes are happening in similar ways in both the U.S. and Europe.

Those are the findings of a new study in the journal Science.

Phil Stephens is a senior lecturer in ecology at Durham University in the UK, and he’s a lead author of the study. 

Stephens and an international team of researchers studied data on more than 500 common species of birds over a 30 year period (1980-2010) in both Europe and the U.S.

If you want to help reduce greenhouse gases - without a major change in life style, the best single action is to drive a more fuel efficient car.

According to a new study by researchers at the University of Michigan Transportation Research Institute,  if every American were to drive a car that gets 31 mpg, instead of the current average of 21.4 mpg, total U.S. carbon emissions would drop by 5 percent.  Driving a vehicle that gets 56 mpg would mean a 10 percent drop.

Attacking the science behind climate change effectively sways public opinion, according to a recent study by Michigan State University researchers.

MSU associate professor and sociologist Aaron McCright led the study of 1600 US adults.

McCright says messages that frame climate change as a public health or national security threat, or even through a “positive” frame like economic opportunity or religious obligation, seem to fall flat.

After the Paris climate agreement, it looks like 2016 could be a big year for new climate change and energy policies in the U.S.

And if Michigan businesses haven't already started preparing for new energy markets and a changing climate, they'll need to soon, says Andrew Hoffman, Professor of Sustainable Enterprise at the University of Michigan’s Ross School of Business.

"Any business who hasn't been looking at least at, where are our greenhouse gas emissions coming from? What will it cost to reduce them? Where will it be cheapest, where will it be most expensive?"

Lakes are getting warmer worldwide

A study of 235 lakes around the world shows water temperatures are on the rise. The overall average increase was 0.61 degrees per decade over the past 25 years. Four of the five Great Lakes were included in the study, with deeper, colder Lake Superior showing the biggest temperature gain – about three times the worldwide average.

The ongoing temperature change could be damaging to Michigan's lake ecosystem and economy, says Donald Uzarski, director of the Institute for Great Lakes Research at Central Michigan University.

Aptly enough, it was 60 degrees in Michigan, in December, the day that 195 nations agreed to take steps to reduce carbon emissions.

Carbon dioxide from those emissions is heating the atmosphere, melting glaciers, and increasing sea levels.

In Ann Arbor, several hundred people joined a "Michigan Climate March," not to protest the accord, really, but to demand that governments go further.

At a rally following the march through city streets, participants held aloft signs bearing messages like, "I Love Clean Air," and "This is a Crisis."

As 190 nations try to finalize a climate change agreement in Paris, activists around the world are planning marches and rallies in support of that agreement.

But it won't be enough, says Nicholas Jansen of the group 350.org, so named for a reduction to 350 parts CO2 per million that the group is pushing the world to achieve.

That's why his group, and others around the world, will immediately begin pressuring their governments to go far beyond what is agreed to in Paris.

Jansen says the U.S. needs to play a large role.

Coal is an abundant source of energy.  But burning it spews billions of tons of climate-warming CO2 into the air every year.

Much hope has been placed on a developing technology known as carbon capture and sequestration (CCS).  The idea is to extract the carbon before it’s emitted from smokestacks, compress it, and store it underground. 

That could allow humans to keep using coal, without further loading the atmosphere and oceans with more CO2.

The flooding event in Detroit fits the global warming pattern, according to reports such as National Climate Assessment.

In 1997 world leaders met Kyoto, Japan to set goals to curb carbon emissions in response to the threat of global climate change. While some nations strove to meet those goals, other countries ignored them. Almost 20 years later, the world community is meeting again to come up with a global plan to fight climate change. 

General Motors

The Obama Administration says 13 of the nation's largest companies are taking the "American Business Act on Climate Pledge," including General Motors.

Other companies pledging to significantly reduce their carbon emissions are Alcoa, Apple, Bank of America, Berkshire Hathaway Energy, Cargill, Coca-Cola, Goldman Sachs, Google, Microsoft, PepsiCo, UPS, and Walmart.

A new effort led by the private sector in Grand Rapids will try to cut water, energy use and transportation emissions in half over the next 15 years.

More than a dozen businesses, including Spectrum Health, Consumers Energy, Rockford Construction and SMG, which manages DeVos Place and Van Andel Arena, have agreed to the general concept. A new committee will draft details of the plan this year.

U.S. Agriculture Secretary Tom Vilsack believes farmers can do more to combat climate change. 

He spoke to an audience of farmers and agri-business leaders this afternoon at Michigan State University.

Vilsack says farmers are very familiar with the effects of climate change.
