San Francisco’s zany Bay to Breakers race brings out not only world class runners but crazy costumes as well. Some companies took advantage of the crazy and healthy atmosphere to promote various items (energy drinks, anti pain patches) but we had to question the Foster Farms “Say No to Plumping” race team.

Sure, everyone seemed to enjoy having their photo taken with the plump Foster Farms chickens but the brightly colored 16-person Foster Farms race team seemed bent on raising awareness of a little-known food fact: “plumped” or saltwater-injected chicken that costs consumers their health and money.

Nasa scientists have told government’s that a simple cut in worldwide emissions of soot could lead to a dramatic reduction in the effects of global warming, as well as preventing hundreds of thousands of deaths from air pollution.

Soot contains black carbon, thought to be the second largest cause of global warming after carbon dioxide. Whilst airborne, it it spread around the globe by wind, heating the atmosphere by absorbing and releasing warmth from the sun’s rays. When it falls to the surface it also darkens snow and ice in polar regions or high mountain ranges, further reducing the Earth’s ability to reflect solar radiation.

Cutting soot emissions has a virtually instantaneous effect since it disappears rapidly from the earth’s atmosphere, unlike CO2, which can linger for hundreds of years.

A team of UK scientists have discovered a natural process that could delay, or even end, the threat of global warming.

The researchers, aboard the Royal Navy’s HMS Endurance, have found that melting icebergs off the coast of Antarctica are releasing millions of tiny particles of iron into the southern Ocean, helping to create huge ‘blooms’ of algae that absorb carbon emissions. The algae then sinks to the icy depths, effectively removing CO2 from the atmosphere for hundreds of years.

According to lead researcher, Prof. Rob Raiswell of Leeds University, “The Earth itself seems to want to save us.”

This is one of the most succinct illustrations of the story of Earth’s recent life, as endured with a case of Humans. It even leaves the door open for sequels, as we all wait to see where humans go next — Mars? — and what they do there. Oh, the suspense.

Scientists at Columbia University have discovered that a rock found in the Middle East can be used to soak up carbon dioxide at a rate high enough to significantly slow global warming.

The team found that when the rock, known as Peridotite, comes into contact with carbon dioxide it converts the gas into harmless minerals such as calcite. They have also worked out a way to ’supercharge’ the naturally occurring process to a million times its normal speed to grow enough of the mineral to permanently store 2 billion or more tons of carbon dioxide annually. This equates to an astonishing 7 per cent of the total global carbon emissions from human activity each year.

Nature has finally confirmed it: the industrialized nations may be rich but the air that people breathe in poorer nations in the Southern Hemisphere is cleaner four times over.

A chemical equator - an atmospheric line - discovered by scientists suggests the existence of a 50 kilometer-wide boundary between polluted air of the Northern Hemisphere and the largely uncontaminated atmosphere of the Southern Hemisphere.

In a model, the red that represents high levels of carbon monoxide present in the air in the Northern Hemisphere gives way to blue that reflects clean air of the South; in between, a white-colored ‘chemical equator’ separates them.

Over our history eclipses have been the portent of the gods wrath, new things to come, or simply a pretty light show. But would you have expected our last lunar eclipse to have been of any help to researchers looking at climate change?

Researchers at the University of Colorado in Boulder, US, found that Earth’s atmosphere contained very little light-blocking volcanic dust. During the eclipse, Earth blocks sunlight from reaching the moon – hence why [...]

I played around for a few minutes with a heading that said something along the lines of “Scientists alert us to the Obvious… etc” for this story. It seems to me that I am dealing more and more with people who simply intend to live their lives with their heads buried in the sand.

That isn’t to say that [...]

Could he see where it would end?

Turner, arguably the greatest artist Britain has ever known, painted the scene above. A steam tug tows a wind-powered warship to its grave. The sun sets. It’s not optimistic. Maybe not pessimistic either, yet the artist knows something has changed. Wind power is no longer an option. It’s 1838.
