Kids paying cash for lunch eat healthier, Cornell study shows

January 17th, 2014

The more current the currency, the better kids eat, according to a study that looked at how payment methods in public school lunch systems affect food choices. The study, by Cornell researchers funded with a government grant, looked at two types of payment methods in public school cafeterias, those that accept only pre-loaded debit cards and those that accept cash or debit card.

And the Top 10 ‘Cool Schools’ for 2013 are….

August 14th, 2013

Sierra magazine has released its Cool Schools rankings for 2013, revealing that the nation’s campuses are a hotbed of sustainable ideas that are helping cool the planet and set the pace for a new generation ready to confront climate change. We take a look at the Top 10….

Cornell students fuse design and urban agriculture, creating the Hydroponic Bottle Wall

August 13th, 2013

Urban agriculture doesn’t look anything like traditional agriculture. But that can be a good thing, as urban architecture and design weaves food into unlikely spaces, making them more utilitarian and also more beautiful, like this unique project by Cornell University students.

Cornell study finds that natural gas can help slow global warming quickly

July 10th, 2012

ITHACA, N.Y. – No matter how you drill it, using natural gas as an energy source is a smart move in the battle against global climate change and a good transition step on the road toward low-carbon energy from wind, solar and nuclear power.

Arctic ice melt will bring more severe winters, according to Cornell scientists

June 6th, 2012

ITHACA, N.Y. – The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think.That’s because melting Arctic sea ice can trigger a domino effect leading to increased odds of severe winter weather outbreaks in the Northern Hemisphere’s middle latitudes – think the “Snowmageddon” storm that hamstrung Washington, D.C., during February 2010.

Methane gas from fracking will worsen climate change, report Cornell researchers

January 20th, 2012

Groups protesting natural gas drilling have focused on the threat to water supplies. They point to the modern drilling or “fracking” methods, which shatter rock deep beneath the earth, opening fissures that threaten water stores; and they cite cases of wells being contaminated near fracking operations in Pennsylvania and Wyoming.
Now new research by three Cornell University scientists suggests that fracking could cause even more havoc with the atmosphere

Cornell scientists say methane leaks from ‘fracking’ could be worse than emissions from coal and oil

April 12th, 2011

A Cornell review of natural gas extraction methods reveals that ‘fracking’ gas from the Marcellus Shale region of New York and Pennsylvania could release dangerous amounts of methane gas, causing more damage to the atmosphere per pound than even carbon dioxide.

Natural gas, which burns cleaner (producing less carbon dioxide) than gasoline, diesel fuel and coal has been touted as a greener “bridge fuel” that could power cars and replace coal in power plants. Tailpipe emissions from natural gas-powered vehicles emit few greenhouse gases.

But Cornell ecologist Robert Howarth warns that the natural gas extraction or drilling process releases dangerous amounts of methane, a greenhouse gas far more potent than carbon dioxide. The methane leakage is the worse when the gas is accessed by the hydraulic fracturing or ‘fracking’ methods that have become popular with the industry. Fracking is a way of teasing out deeply embedded gas deposits using high pressure water injections in wells that run both vertically and horizontally through shale deposits.

Cornell professors offer advice for helping trees survive heat

August 9th, 2010

This year is well on its way to becoming the hottest year the world has seen since scientists began record-keeping in 1880. According to the National Oceanic and Atmospheric Administration (NOAA), the rising worldwide temperatures are responsible for erratic weather – including severe droughts and heat waves.
What does this mean for your lawn and trees? Two experts from Cornell University have some advice that may surprise you.

Biochar: Panacea or peril?

July 19th, 2010

Biochar has emerged over the last couple years as a ray of hope on the otherwise bleak horizon of the planet’s environmental future. It has been hailed as a possible solution to climate change, world hunger, and rural poverty — though doubts are being raised in some quarters.
Last year, some of the world’s most eminent biochar experts gathered for a biochar conference at the University of Massachusetts-Amherst to discuss this ancient technology that is getting a new look by scientists, governments and investors. To the packed audience, this promising technology sounded like a panacea for a whole host of problems. Biochar, the speakers said, could soak up large amounts of carbon from the atmosphere, supercharge soil fertility to feed the world’s hungry, promote jobs and economic opportunities for farmers, safely get rid of animal and plant waste, heat buildings greenly, and slash the kind of fertilizer use that is creating vast dead zones in coastal waters from nitrogen runoff.

New oil incursion at Raccoon Island blackens the future for pelican chicks

Gulf-area biologists and researchers from Cornell University have discovered that birds on previously unaffected Raccoon Island have been newly oiled, apparently because of waves of crude driven in by winds from Hurricane Alex.

Expert: Public missing full impact of Gulf oil spill

July 13th, 2010

While tar balls, oil-covered birds and dying turtles are the prevailing images of the Gulf oil spill, at least one marine biologist believes the public many not fully grasp the scope of the disaster. “Birds, sea turtles, and dolphins get most of the press, but all marine organisms in the Gulf of Mexico are threatened by the catastrophic oil spill,” says Paula Mikkelsen, a visiting fellow in Cornell University’s department of Ecology and Evolutionary Biology and an associate director of the Cornell-affiliated Paleontological Research Institution. “Every habitat – from intertidal oyster bars and mangroves to deepwater sand plains — depends upon clean water to survive.”
