from TIME Magazine:
How Global Warming will Change Ecosystems
...It's reasonable to expect, for example, that ecosystems will change as plants and animals respond to a rising thermometer -- but how do you measure the change of an ecosystem that may consist of hundreds or even thousands of species?... A team of scientists led by Stephen Thackeray, an expert on lake ecology at the United Kingdom's Centre for Ecology and Hydrology, has combed through observations of more than 700 species of fish, birds, mammals, insects, amphibians, plankton and a wide variety of plants across the U.K. taken between 1976 and 2005, and found a consistent trend: more than 80 percent of "biological events" -- including flowering of plants, ovulation among mammals and migration of birds -- are coming earlier today than they were in the 1970s.
On average, these events are occurring about 11 days earlier, and the pace of change has been accelerating with every decade.

Witnessing Uplifting Behavior May Spur Good Deeds
Seeing someone else do a good deed appears to inspire you to do the same by making you feel uplifted, new research suggests.
In an experiment, researchers recruited volunteers who watched a "neutral" video clip of scenes from a nature documentary or a clip from "The Oprah Winfrey Show" in which musicians thanked their mentors. The participants then wrote essays about what they watched, were paid for their time and asked to indicate whether they'd want to take part in another study.
Those who saw the Oprah Winfrey clip were more likely to volunteer to take part in another study.
The positive, uplifting emotion that makes people feel good and may inspire them to help others is known as "elevation," the researchers explained in a news release about the experiment from the Association for Psychological Science. ...

But what if it's only Oprah that has this power to inspire?

Tofu can harm environment more than meat, finds WWF study
Becoming a vegetarian can do more harm to the environment than continuing to eat red meat, according to a study of the impacts of meat substitutes such as tofu.
The findings undermine claims by vegetarians that giving up meat automatically results in lower emissions and that less land is needed to produce food.
The study by Cranfield University, commissioned by the environmental group WWF, found that many meat substitutes were produced from soy, chickpeas and lentils that were grown overseas and imported into Britain.
It found that switching from beef and lamb reared in Britain to meat substitutes would result in more foreign land being cultivated and raise the risk of forests being destroyed to create farmland. Meat substitutes also tended to be highly processed and involved energy-intensive production methods. ...

Glaciers: Changing at a Less Than Glacial Pace
...a new study published in the Feb. 12 issue of Science indicates that the balance of the world's ice may be shifting faster than scientists thought, which may have consequences in a warming world. A team of scientists traveled to the Spanish island of Mallorca, where they visited a coastal cave that has been submerged off and on by the Mediterranean Sea for hundreds of thousand of years, as glacial periods have waxed and waned. They dated the layers of the mineral calcite, which were deposited by the seawater in rings on the cave walls, as on a bathtub.... "It's fair to say that this means glaciers may change somewhat faster than we once inferred," says Jeffrey Dorale, a geoscientist at the University of Iowa and the lead author of the Science paper.

Maybe we need a different word for "glaciers." How about raciers?

from BBC:
Climate change will make world more 'fragrant'
As CO2 levels increase and the world warms, land use, precipitation and the availability of water will also change.
In response to all these disruptions, plants will emit greater levels of fragrant chemicals called biogenic volatile organic compounds.
That will then alter how plants interact with one another and defend themselves against pests, according to a major scientific review.
According to the scientists leading the review, the world may already be becoming more fragrant, as plants have already begun emitting more smelly chemicals. ...

Plus, there'll be the additional smell of us crapping our pants!

from Washington Post:
U.S. proposes new climate service
The Obama administration proposed a new climate service on Monday that would provide Americans with predictions on how global warming will affect everything from drought to sea levels. The National Oceanic and Atmospheric Administration Climate Service, modeled loosely on the 140-year-old National Weather Service, would provide forecasts to farmers, regional water managers and businesses affected by changing climate conditions... A Web portal launched Monday at www.climate.gov provides a single entry point to NOAA's climate information, data, products and services. ...

from Chicago Tribune:
Chicago schools pile up lunch waste
...Every day, kids in the Chicago Public Schools district throw out nearly a quarter of a million lunch and breakfast trays made of polystyrene foam. That's more than 1 million a week, about 5 million a month.
And those trays are just the start of a river of trash from school meals that ends up in landfills, including nacho-stained containers, half-empty milk cartons, plastic cookie wrappers and plastic tubs that will sit in thick polyethylene bags for centuries without biodegrading.
The Prosser students, led by biology teacher Marnie Ware, found their Belmont-Cragin-area school created 1,500 pounds of cafeteria garbage a day over five periods, including breakfast. ...

from Der Spiegel:
Global Ocean Protection Measures Have Failed
Thousands of tons of trash are thrown into the sea each year, endangering humans and wildlife. A classified German government report obtained by SPIEGEL ONLINE indicates that efforts by the United Nations and the European Union to clean up our oceans have failed entirely.
Since the world's oceans are so massive, few people seem to have a problem with dumping waste into them. But plastics degrade at very a slow rate, and huge amounts of them are sloshing around in our oceans. Wildlife consumes small pieces causing many of them to die, since the plastics are full of poisons. And, as experts warn, we've reached a point where it's even getting dangerous for humans to consume seafood... Our oceans have devolved into vast garbage dumps. ...
