NOAA: Summer 2012 third hottest on record, see how local climate has changed

The redder the higher the difference from average temperature, June-August 2012.
NOAA

The National Oceanic and Atmospheric Administration's National Climatic Data Center reported today that the summer of 2012 "was the third hottest summer on record for the contiguous United States since recordkeeping began in 1895."

They looked at records from June through August of 2012 (summer is technically over on the morning of September 22).

...the average temperature for the contiguous United States between June and August was over 74° Fahrenheit, which is more than 2° F above the twentieth-century average. Only the summers of 2011 and 1936 have had higher summer temperatures for the Lower 48.

The online weather service, the Weather Underground, has compiled data that allows users to look at how their local climate has changed over the years.

It also allows users to see how local the climate is expected to change in the coming years using two different IPCC greenhouse gas emissions models.

Researchers measure role of urban greenery in carbon dioxide exchange

Emily Peters measures photosynthesis on trees in a suburban neighborhood from an aerial lift truck.
University of California-Santa Barbara

Scientists know a lot about how natural places process carbon dioxide.  But there hasn’t been a lot of research into what happens throughout the year in the green spaces in cities and suburbs.

Emily Peters is an author of a paper out this week in the Journal of Geophysical Research.  She’s been looking at how plants and trees in one suburban neighborhood take in carbon dioxide during the year... and how they offset the carbon dioxide people in the neighborhood emit – by say, driving their cars.

“In the summer we found the uptake of carbon dioxide from the vegetation is enough to offset fossil fuel emissions – just in the summer.”

She says evergreen and leafy trees took in more CO2 during the middle of the summer. Lawns did the best job of taking in CO2 during the spring and fall.  But Peters says those plants did NOT balance out the total amount of carbon dioxide released in the suburban neighborhood by burning fossil fuels over the year. 

If you're wondering: do certain species of trees do a better job than others?

"That is the question everybody wants answered - we can’t go out with this study and tell city foresters they should plant more of this kind of tree vs. this kind of tree."

Michigan retailers importing cherries

Smeltzer Orchards in northern Michigan had to import cherries - for the first time ever.
Bob Allen

When you scoop up ice cream with cherries in it this summer or add a handful of dried cherries to your salad chances are the fruit won’t be from Michigan. Or even from the United States.

Extremely unusual weather this spring has crippled the state’s entire tree fruit industry. The bulk of the nation’s tart cherry crop is produced here.

The official estimate for the size of the cherry crop won’t be in for a few more weeks.

Even the most optimistic projections for the amount of fruit on the trees amounts to less than ten percent of what the state typically grows.

Tim Brian is president of Smeltzer Orchards in Benzie County.

He grabs a stem from a tart cherry tree and with his thumbnail slices open several buds.

"And right there you can see that brown pistil right there, that’s cooked. There isn’t a single good one in this whole cluster."

A bizarre stretch of hot weather in early March woke trees up from winter dormancy. That was followed by more than a dozen nights of hard freezing temperatures.

Brian thinks there will be entire orchards that won’t be harvested at all this year even if there is a scattering of fruit in them.

"I mean, with $4 fuel, even if there is only ten cherries on a tree that’s not going to be economically feasible to harvest."

Smeltzer’s has been in the business for well over a century.  The company runs a medium sized processing plant that freezes and dries cherries.

Inside the plant, a dozen people are pitting and sorting sweet cherries. The thing is… these cherries are from Chile.

"Normally we would not do this. This is actually the first time we’ve done something like this."

Study finds large majority of Americans connect extreme weather events to climate change

You’ve probably noticed we’ve had a strange spring.

This March – the warm temperatures broke 15,292 weather records across the country.   And last year... there were 14 weather-related disasters that each caused $1 billion – or more – in damages.

A new study finds a large majority of Americans are now connecting specific extreme weather events to climate change.

The study is part of a long-term project called Climate Change in the American Mind.  It’s by the Yale Project on Climate Change Communication and George Mason University's Center for Climate Change Communication.

Here's an excerpt:

A majority of Americans say the weather in the United States is getting worse and many report that extreme weather in their own local area has become more frequent and damaging. Further, large majorities believe that global warming made a number of recent extreme weather events worse. Only about a third of Americans, however, have either a disaster emergency plan or an emergency supply kit in their homes.

Ed Maibach directs George Mason’s climate change center.  He and his colleagues found that 82 percent of Americans personally experienced one or more types of extreme weather or natural disaster in the past year.  I asked him how these experiences are affecting people’s understanding of climate change.

"We know that most Americans believe the climate is changing, and now, this latest survey shows us that a lot of people are connecting the experience of the extreme weather they’re experiencing to the fact that the climate is changing."

But he says not too many people understand the difference between weather and climate.

Study: Electric cars produce fewer emissions than hybrids... sometimes

A new study says electric cars produce fewer global warming emissions than hybrids - in some regions. 

The Union of Concerned Scientists says electricity in California and New York isn't as reliant on older, coal-burning power plants as other regions.

Hard freeze hurts Michigan cherry crop

A hard freeze has wiped out a big portion of the cherry crop in Northwest Michigan this spring.  The area produces more than half the state’s cherries that end up in desserts, juice and as dried fruit.

An historic early warm-up in March left fruit trees vulnerable to frost once the weather turned cooler again.

Temperatures broke records for the month of March across the Great Lakes region.

Climate researchers say there’s never been anything like it going back more than a hundred years.

“We’re seeing history made before our eyes at least in terms of climatology.”

Jeff Andresen is the state’s climatologist and professor of geography at Michigan State.

“And in some ways if we look at where our vegetation is and how advanced it is, it’s probably a month ahead of where it typically is.”

Andresen is careful to point out that this year’s early warm-up is an extreme weather event.

He says it far outpaces the previous warmest March on record in 1945.

He can’t say it’s a direct result of climate change.

But it fits the predicted long term pattern of change that includes extreme fluctuations.

Designing buildings for a changing climate in the Great Lakes region

U.S. Forest Service

A group of planners and designers is arguing that we need to rethink the way we make our buildings. The U.S. Green Building Council and the University of Michigan recently put out a report: Green Building and Climate Resilience.

It says design teams should start making buildings that are better suited to a changing climate. That could mean redesigning heating and cooling and storm water systems, and it could mean changing the kind of landscaping we do.

Larissa Larsen is the lead author of the report. I met up with her on a corner in Ann Arbor to take a look at a new high rise apartment building that’s going up.

“This looks like a fairly traditional apartment building and that’s completely fine. We want to start thinking that this building is going to be inhabiting conditions that are different than what has been in Michigan for a long time.”

The Great Lakes - On Thin Ice?

DULUTH, Minn. (AP) — A published report says the amount of ice covering the Great Lakes has declined about 71 percent over the past 40 years.

The report published last month by the American Meteorological Society says only about 5 percent of the Great Lakes surface froze over this year.

A Duluth News Tribune report (http://bit.ly/z5DoW8 ) says researchers determined ice coverage by scanning U.S. Coast Guard reports and satellite images taken from 1973 to 2010.

Northern Michigan fruit growers brace for a changing climate

Warmer temperatures and melting snow are less than ideal for winter sports and outdoor festivals. But the weird weather has northern Michigan fruit growers holding their breath, hoping to avoid disaster.

In his more than 20 years as an agricultural extension agent in the Traverse City area, Duke Elsner says this is the most bizarre winter weather he’s ever seen.

“The ups and downs have just been remarkable. The inability to hang on to a cold period for any length of time has been very strange.”

A gradual drop in temperature at the beginning of winter and holding there below freezing for long periods are the ideal conditions for plant to become frost hardy, and hardiness is what protects them from getting damaged by cold.

But when temps bounce up into the 40’s and 50’s as they’ve done frequently this winter, some of that hardiness is lost.

“Our trees and vines can take below zero in a normal winter. I sure wouldn’t want to drop below zero at this point in time, I’ll say that.”

That’s fruit grower Jim Nugent. He and a couple of his neighbors are doing the yearly chore of pruning his cherry trees.  With long-handled saws, they reach up eight or ten feet to strip away branches and limbs.

Nugent knows his orchard is vulnerable right now because of a loss of winter hardiness. But there’s not a lot he can do about it.

Things could go either way at this point.

A sudden drop to zero would be serious.

But orchards still may slide by unscathed. If temps gradually drop below freezing and stay there, trees will regain some of their hardiness.

Breaking through to climate change skeptics

Photo courtesy USFWS

Anthony Leiserowitz directs the Yale Project on Climate Change Communication. He says the vast majority of scientists agree that climate change is real. It’s mostly caused by people. And it’s serious.

“We know through multiple studies that over 95% of scientists agree about this.”

But... he says his studies and others show the number of Americans who believe climate change is happening has declined. 

Leiserowitz says there are a lot of reasons for that. A tough economy... declining media coverage...

“Then there’s actually been a very active campaign to discredit the science, to put out disinformation about the science. And that really kicked into gear in 2008 and 2009 because Congress was about to pass climate legislation. Forces that are perfectly happy with the status quo worked very, very hard to stop that effort and they were successful.”

So as a result of these factors and others... he says many Americans are confused about what to believe... or downright skeptical.

This was the topic of a conference put on by the Erb Institute for Global Sustainable Enterprise and the Union of Concerned Scientists at the University of Michigan last week. There were social scientists and climate scientists, religious leaders and members of the business community. They were here to talk about how the public climate change debate has become more about personal values and how you see the world than about the science.

Wangari Maathai, winner of Nobel Peace Prize, dies

Wangari Maathai in Kenya in 2004 - the year she won the Nobel Peace Prize.
Mia MacDonald Green Belt Movement

Wangari Maathai, the first African woman to win the Nobel Peace Prize died on Sunday in her native Kenya.  She was 71.

The New York Times reports:

The cause was cancer, her organization, the Green Belt Movement, said. Kenyan news organizations said she had been treated for ovarian cancer in the past year and had been in a hospital for at least a week when she died.

Maathai was a leading environmentalist and feminist as well as a human-rights advocate.  She has also worked to encourage nations around the world to work together to reduce the greenhouse gas emissions causing climate change.

During an interview on Michigan Radio's The Environment Report in 2009 (click on audio above), Maathai also called on everyone to help work to solve the global warming problem.

"I think it’s very important to encourage farmers, individual citizens to plant trees. And, I’m very happy to know that in some of your states, tree planting has been embraced as one of the solutions. It’s one of the activities that every one of us citizens can do and feel good about it, and teach kids to do it, because every tree will count. And when there are 7 billion of us, almost, in the whole world, so you can imagine, if every one of us planted a tree and made sure that tree survived – can you imagine the impact?"

Climate change & Great Lakes restoration

Photo by Rebecca Williams

There’s an enormous project underway to clean up and protect the Great Lakes. It’s called the Great Lakes Restoration Initiative. People are doing things like cleaning up toxic hot spots... restoring wetlands... and trying to keep Asian Carp out of Lake Michigan.

Melinda Koslow is with the National Wildlife Federation. She’s an author of a new report on how climate change might affect these projects. She says scientists are finding the climate in the Great Lakes region is already changing.

Blocking EPA's regulation of greenhouse gasses

Michigan Congressman Fred Upton (R)
Republican Conference Flickr

The U.S. Supreme Court ruled four years ago that the Environmental Protection Agency has the authority to regulate planet-warming greenhouse gasses... if the agency found those gasses are a threat to human health and safety. In 2009, the EPA found greenhouse gasses are a threat... and the agency started taking steps to regulate emissions from industries such as coal-burning power plants and automobiles.

For months now, many members of Congress have been trying to block the EPA from doing that. The latest people to climb on board are from Michigan: Republican Representative Fred Upton and Democratic Senator Debbie Stabenow.

Fred Upton chairs the U.S. House Energy and Commerce Committee. He not only wants to stop the EPA from regulating greenhouse gasses... he wants to repeal the EPA’s scientific finding that greenhouse gasses are harmful.

Ryan Werder is the political director for the nonpartisan group Michigan League of Conservation Voters. He says since he was appointed Chair, Congressman Upton has shifted to the right politically.

“He was always a good, moderate, reliable voice. Before, when he said climate change was a reality and something we had to consider. He suddenly removed that from this website and acts as if climate change is non-existent.”
