Reverse Circulation in Atlantic Ocean

this wil make your toilet spin the other direction upon a flush. Fear not.

Universitat Autònoma de Barcelona scientists have researched how ocean currents in the Atlantic were affected by climate change in the past. The study shows that there was a period when the flow of deep waters in the Atlantic was reversed. The results are relevant for the near future since similar changes are expected to occur in the course of climate warming over the next 100 years.

Water Flowing Through Ice Sheets Accelerates Warming

“The earths natural slushy!”

Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to climate change, according to a new study involving the University of Colorado at Boulder.

Eating makes You Emit 2 Tons of CO2 a Year ?!

I’ll give you one guess were the CO2 was released from in this photo

Every person emits the equivalent of approximately two tonnes of carbon dioxide a year from the time food is produced to when the human body excretes it, representing more than 20% of total yearly emissions. That is what a study by the Universidad de Almería says, confirming for the first time that human excrements contribute to water pollution, primarily with nitrogen and phosphorus.

Pollution from Asia Circles Globe at Stratospheric Heights

100325143047-large

Factories line the shores of the lower Yangtze River in China. Heavy pollution tied to China’s rapid industrial growth has produced poor visibility and health effects.

The economic growth across much of Asia comes with a troubling side effect: pollutants from the region are being wafted up to the stratosphere during monsoon season. The new finding, in a study led by scientists at the National Center for Atmospheric Research, provides additional evidence of the global nature of air pollution and its effects far above Earth’s surface.

Upside-Down Answer for Deep Mystery: What Caused Earth to Hold Its Last Breath?

100217131140-large

Volcano eruption

When Earth was young, it exhaled the atmosphere. During a period of intense volcanic activity, lava carried light elements from the planet’s molten interior and released them into the sky. However, some light elements got trapped inside the planet. In the journal Nature, a Rice University-based team of scientists is offering a new answer to a longstanding mystery: What caused Earth to hold its last breath?

A new study links springtime ozone in North America with pollutants from Asia

Such increases in ozone could make it more difficult for the United States to meet Clean Air Act standards for ozone pollution at ground level, according to a new international study. Published online January 20 in the journal Nature, the study analyzed large sets of ozone data captured since 1984.

Alligators Breathe Like Birds, Study Finds

Computerized tomographic (CT) X-ray images of side and top views of a 24-pound American alligator, with 3-D renderings of the bones and of airways or bronchi within the lungs.

University of Utah scientists discovered that air flows in one direction as it loops through the lungs of alligators, just as it does in birds. The study suggests this breathing method may have helped the dinosaurs’ ancestors dominate Earth after the planet’s worst mass extinction 251 million years ago.

Amphibians, for years considered a leading indicator of environmental degradation, are not uniquely susceptible to pollution, according to a meta-analysis to be published in Ecology Letters.

Hemigraphis alternata, or purple waffle plant, one of the highest ratedornamentals for removing indoor air pollutants.


Air quality in homes, offices, and other indoor spaces is becoming a major health concern, particularly in developed countries where people often spend more than 90% of their time indoors. Surprisingly, indoor air has been reported to be as much as 12 times more polluted than outdoor air in some areas. Indoor air pollutants emanate from paints, varnishes, adhesives, furnishings, clothing, solvents, building materials, and even tap water.

Banded Rocks Reveal Early Earth Conditions, Changes

Pictured in 2008, a banded iron formation about 2.5 billion years old near Soudan Underground Mine State Park in Minnesota shows alternating layers of silica-rich (red) and iron-rich (gray) minerals.

The strikingly banded rocks scattered across the upper Midwest and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than 2 billion years ago. Continue reading… “Banded Rocks Reveal Early Earth Conditions, Changes”

Acidic Clouds Nourish World’s Oceans

091005102645-large

Water droplets in clouds generally form around dust and other particles. When clouds evaporate, as they often do naturally, the surface of the particle can become very acidic. This is especially true where the air is polluted.

Scientists at the University of Leeds have proved that acid in the atmosphere breaks down large particles of iron found in dust into small and extremely soluble iron nanoparticles, which are more readily used by plankton.
