Overall, global CO2 emissions from fossil fuels increased 29% between 2000 and 2008 and 41% from 1990-2008, and the current concentration of CO2 in the atmosphere is now at its highest in at least 2 million years, according to a new study in the journal Nature Geoscience.

The new report published this week by an international team of researchers who are part of the “Global Carbon Project” shows emissions trends through 2008 (including changes in emissions causes and in the amount of emissions remaining in the atmosphere) and brings up some major questions for the future as well.

With concerns over climate change globally, you might think that the last thing that environmentalists would worry about would be the natural food chain of wildlife; but for the Great Lakes there could be severe consequences posed if the carp manage to enter waterways they’ve been barred from entering.

Oceans regulate our climate. They play a key role in keeping the world’s “homeostasis” in tact. However, their ability to absorb carbon & keep the climate in balance is dwindling, a new report shows.

In a year-by-year study from 1765 to 2008, researchers found that the oceans are struggling to meet increasing emissions demands. They cannot take in as much carbon as they used to.

The study, published in the November 19 issue of the journal Nature, found that the percentage of fossil fuel emissions the ocean has been taking in since 2000 has decreased by as much as 10%.

This is the first study of its kind or breadth. One previous study had attempted to measure the oceans’ industrial carbon absorption for one year — 1994. This does so for a period of 200+ years.

Thanks to rampant poaching and habitat destruction, rhinos have the unfortunate distinction of being one of the most endangered animals on earth.

Over the last 30 years, the world’s overall rhinoceros population has declined by over 90% - and if not for dedicated conservation efforts over the last 100 years, it is likely that all rhinoceros species would already be extinct.

To help raise awareness for these proud pachyderms, here are 11 incredible facts about rhinos - plus a compilation of beautiful photos (except for one very graphic photo) and a couple of videos, too. Enjoy!

With bike weddings, bike parades, hundreds of naked bicyclists, bike fashion shows, popular & interesting cargo bikes, and travelling bike pubs, Portland is #3 on this great bicycle city photo tours list.

Portland has great bicycle facilities (colored bike lanes, bike boxes at intersections, great bike signs, off-road bicycle paths, etc.), a large number of people using the bicycle for transportation, and a bike culture that brings the fun of bicycling to another level.

As a result of these factors and more, Portland was the first large city in the US to achieve the Platinum level Bike Friendly award from the League of American Bicyclists (LAB) — the Platinum level being the highest level possible (above Gold, Silver and Bronze). It is truly a world-class bicycle city now, and the amazing photos in this photo tour help to show that.

The awesome power released by a detonating mine

The New Mine Detection Technology

Researchers at the University of Edinburgh have engineered a bacteria using the latest BioBrick technology. BioBrick an open source technology of the BioBricks Foundation, a not-for-profit organization founded by engineers and scientists from MIT, Harvard, and UCSF. Simplistically stated, it offers the ability to introduce standardised strands of DNA with known function into bacteria. In this case the Bricks gave the ability to detect the chemicals leaked by buried explosives and to produce chemicals that cause it to glow green. Linking these new functions together produces a safe, easy to grow bacteria that after application to the ground in a coulourless liquid glows green within a few hours. With the location of the mine noted, de-mining can be undertaken quickly without the risk of undetected mines.

A trek across a frozen lake proved to be a deadly journey for hundreds of reindeer last week.  Sami herders in Sweden were leading 3,000 reindeer to “greener pastures” across a frequently-traveled route during their annual migration to their winter grazing grounds when tragedy struck.
