Carbon Dioxide Makes You Fat

So sayeth some Danish scientists, as reported in Science Nordic:

No, this is not 1 April — and this is not an April Fool’s hoax. Mad as it may sound, Danish researchers have announced a theory that may not only explain why people all over the world are getting fatter and fatter, but also warn of the serious consequences for life on Earth of continued pollution of the atmosphere by CO2 emissions. In itself, the theory is quite simple: CO2 contributes to making us fat.

Rising CO2 ‘Driving Fish Crazy’

Via Common Dreams:

New research shows the disastrous consequences the world’s rising carbon dioxide levels are having on ocean life.

A team of researchers from the Australian Research Council Centre of Excellence for Coral Reef Studies and James Cook University published their findings in the journal Nature Climate Change. They document how elevated CO2 is “driving fish crazy.”

The Australian Associated Press reports that the new research point to ocean problems beyond acidification.  From Professor Phillip Munday, one of the researchers:

”We’ve now established it isn’t simply the acidification of the oceans that is causing disruption, as is the case with shellfish and plankton with chalky skeletons. But the CO2 itself is damaging the fishes’ central nervous systems.”

Agence France-Presse reports:

The team began by studying how baby clown and damsel fishes performed alongside their predators in CO2-enriched water.

They found that while the predators were somewhat affected, the baby fish suffered much higher rates of attrition.

Via ScienceDaily:

Scientists are reporting discovery of an improved way to remove carbon dioxide — the major greenhouse gas that contributes to global warming — from smokestacks and other sources, including the atmosphere. Their report on the process, which achieves some of the highest carbon dioxide removal capacity ever reported for real-world conditions where the air contains moisture, appears in the Journal of the American Chemical Society.

Alain Goeppert, G. K. Surya Prakash, chemistry Nobel Laureate George A. Olah and colleagues explain that controlling emissions of carbon dioxide (CO2) is one of the biggest challenges facing humanity in the 21st century. They point out that existing methods for removing carbon dioxide from smokestacks and other sources, including the atmosphere, are energy intensive, don’t work well and have other drawbacks.

In an effort to overcome such obstacles, the group turned to solid materials based on polyethylenimine, a readily available and inexpensive polymeric material.

Global Carbon Emissions Reach Record 10 Billion Tons

SmokestacksVia ScienceDaily:

Global carbon dioxide emissions from burning fossil fuels have increased by 49 per cent in the last two decades, according to the latest figures by an international team, including researchers at the Tyndall Centre for Climate Change Research, University of East Anglia.Published December 4 in the journal Nature Climate Change, the new analysis by the Global Carbon Project shows fossil fuel emissions increased by 5.9 per cent in 2010 and by 49 per cent since 1990 — the reference year for the Kyoto protocol.

On average, fossil fuel emissions have risen by 3.1 per cent each year between 2000 and 2010 — three times the rate of increase during the 1990s. They are projected to continue to increase by 3.1 per cent in 2011.

Total emissions — which combine fossil fuel combustion, cement production, deforestation and other land use emissions — reached 10 billion tonnes of carbon* in 2010 for the first time.

Climatologist: CO2 Poses No Threat To Human Welfare

You can rely on the “journalists” at Fox News to bring you the latest developments from the “no man-made climate change” camp. In this story they feature a scientist who says his research indicates that CO2 poses no threat to human welfare at all, and he says the EPA should revisit its findings:

Carbon dioxide is hazardous to your health, the Environmental Protection Agency says. Oh really?

EPA scientists say manmade carbon dioxide and other greenhouse gases are contributing to a warming of the global climate — and as such represent a threat to human welfare. Officials went so far as to declare the gas a danger to mankind in early December. But a leading climatologist says his research indicates that CO2 poses no threat to human welfare at all, and he says the EPA should revisit its findings.

“There is an overestimation of the environment’s sensitivity to CO2,” said Dr.
