Are we impacting the future of our planet for thousands of years?

The Earth may suffer irreversible damage that could last tens of thousands of years because of the rate humans are emitting carbon into the atmosphere.

In a new study in Nature Climate Change, researchers at Oregon State University, Lawrence Livermore National Laboratory and collaborating institutions found that the longer-term impacts of climate change go well past the 21st century.

“Much of the carbon we are putting in the air from burning fossil fuels will stay there for thousands of years — and some of it will be there for more than 100,000 years,” said Peter Clark, an Oregon State University paleoclimatologist and lead author on the article. “People need to understand that the effects of climate change on the planet won’t go away, at least not for thousands of generations.”

LLNL’s Benjamin Santer said the focus on climate change at the end of the 21st century needs to be shifted toward a much longer-term perspective.

Over 50 Percent of the World Breathes in Toxic Air

Everyone needs clean air to survive, yet somehow it is not an internationally recognized human right. That probably has something to do with the fact that over half of the world’s population live in areas where they breathe in toxic air. Altogether, that means there are more than 3.5 billion people inhaling dangerous air into their lungs on a daily basis.

Disease may wipe out the world's bananas

Bananas are at the sharp end of industrial agriculture's chemical war on pests and pathogens, writes Angelina Sanderson Bellamy. But even 60 pesticide sprays a year isn't enough to keep the diseases at bay. It's time to seek new solutions with little or no use of chemicals, working with nature, growing diverse crops on the same land - and breaking the dominance of the banana multinationals.

Universtiy of Alaska studies how the melting Greenland glaciers are impacting sea levels

University of Alaska Fairbanks mathematicians and glaciologists have taken a first step toward understanding how glacier ice flowing off Greenland affects sea levels.

Andy Aschwanden, Martin Truffer and Mark Fahnestock used mathematical computer models and field tests to reproduce the flow of 29 inlet glaciers fed by the Greenland ice sheet. They compared their data with data from NASA's Operation IceBridge North aerial campaign.

The comparisons showed that the computer models accurately depicted current flow conditions in topographically complex Greenland.

Who would have guessed this? Study finds vacations can lead to weight gains!

A week's vacation may leave many adults with a heavier midsection--extra weight that can hang around even six weeks post-vacation.

A faculty member in the University of Georgia's College of Family and Consumer Sciences found that adults going on a one- to three-week vacation gained an average of nearly 1 pound during their trips. With the average American reportedly gaining 1-2 pounds a year, the study's findings suggest an alarming trend.

"If you're only gaining a pound or two a year and you gained three-quarters of that on a one- to three-week vacation, that's a pretty substantial weight gain during a short period of time," said Jamie Cooper, an associate professor in the college's department of foods and nutrition.

Man-made underwater sound may have wider ecosystem effects than previously thought

Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton.

The study, reported in the journal Scientific Reports published by Nature, found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

Loss of wild flowers matches pollinator decline

The first Britain-wide assessment of the value of wild flowers as food for pollinators shows that decreasing resources mirror the decline of pollinating insects.

Seafood Consumption May Play a Role in Reducing Risk for Alzheimer's

New research published Feb. 2 in the Journal of the American Medical Association found that older adults with a major risk gene for Alzheimer’s disease known as APOEÉ›4 who ate at least one seafood serving per week showed fewer signs of Alzheimer’s-related brain changes.  In contrast, this association was not found in the brains of volunteers who ate fish weekly but did not carry the risk gene.   

Air pollution in Europe and the EU lack of action

Air pollution from vehicles is killing tens of thousands of people every year in the UK alone, write Jean Lambert, Molly Scott Cato & Keith Taylor, an outrage set into stark focus by VW's 'test cheating'. The EU's response? To relax tests and allow cars to be more polluting - with the full support of the UK government.

Rather than clamping down on the car industry's irresponsible approach to pollution, EU governments and the Commission instead want to rewrite existing law, providing loopholes which will allow cars to legally pollute more.

Faced with a public health crisis, responsible for nearly half a million premature deaths in Europe each year, we would expect an emergency response.

How Modular Construction is Keeping Waste Out of U.S. Landfills

When we think about the overflow of our nation’s landfills, we probably picture limiting our food waste; recycling plastics, glass and paper; and keeping out potentially harmful hazardous waste. What we probably don’t consider is one of the largest sources of waste generation, construction and demolition (C&D) waste.  It is estimated that anywhere from 25 to 40 percent of the national solid waste stream is building-related waste, with only 20 percent of C&D waste being recycled.
