First direct observation of carbon dioxide's increasing greenhouse effect at Earth's surface

Wed, 2015-02-25 13:21
Scientists have observed an increase in carbon dioxide's greenhouse effect at Earth's surface for the first time. They measured atmospheric carbon dioxide's increasing capacity to absorb thermal radiation emitted from Earth's surface over an 11-year period at two locations in North America. They attributed this upward trend to rising carbon dioxide levels from fossil fuel emissions.

One proposal for reversing climate change could alter the appearance of the sky — and that in turn could affect everything from our physical health to the way we see ourselves.

Climate change influences distribution of organic pollutants in the Baltic Sea

Fri, 2015-02-20 08:37
Regional climate change models predict an increased freshwater runoff into the Baltic Sea. This will result in increased inflow of terrestrial dissolved organic carbon. According to researchers, this change will have high impact on the organic pollutants on the organic pollutants in the northern Baltic Sea, since this carbon can interact with the pollutants and decrease their concentration in the water.

Onwards and upwards

VACCINES are medical science’s nuclear weapons. Clean water and sewage disposal aside, they have saved more lives than any other public-health measure. Vaccines have wiped smallpox, a disease once dreaded by rich and poor alike, from the face of the Earth. They may soon do the same to polio. They have driven words like diphtheria and whooping cough from public discourse in rich countries, and might do the same for measles, mumps and rubella were it not for the vanity, selfishness or foolishness of a minority who will not immunise their children against these threats. They also offer the elderly protection, albeit imperfectly, against the lethal ravages of influenza.

But they could do more. Most vaccines are made in ways which would be familiar to Louis Pasteur, the 19th-century French polymath who put vaccination on a scientific footing. Pasteur’s method is either to weaken a pathogen in a laboratory or to kill it outright. The result, when injected or swallowed, acts as an antigen and stimulates an immune response—but it does not cause illness. Thus safely primed, the immune system reacts faster if and when it encounters the real thing.

For those opposing the science surrounding the issue, are they “climate deniers” or merely “skeptics”? And what about “warmistas” vs. “lukewarmers”?

How carbonates behave in Earth's interior

Mon, 2015-02-16 06:47
Carbonates are the most important carbon reservoirs on the planet. But what role do they play in Earth's interior? How do they react to conditions in Earth's mantle? These are the questions being asked by a group of scientific researchers from various geoscience disciplines.

Going negative with carbon

Sat, 2015-02-14 18:45
A growing number of scientists warn that low-carbon technologies might not be enough to curb global warming. The solution, they say, could require a new suite of carbon-negative technologies that actually remove carbon dioxide from the atmosphere.

Stopping at red lights exposes drivers to high levels of air pollution

Thu, 2015-02-12 21:20
UK commuters spend an average of about 1.5 hours a day at the wheel. Road vehicles in particular are known to emit polluting nanoparticles which contribute to respiratory and heart diseases. Now, researchers have found that where drivers spend just 2% of their journey time passing through traffic intersections managed by lights, this short duration contributes to about 25% of total exposure to these harmful particles.

[In Brief] This week's section

In science news around the world, the Institute of Medicine gives chronic fatigue syndrome a new name and recommends new diagnostics, the National Synchrotron Light Source II is dedicated, a National Institutes of Health idea to create an "emeritus award" for aging scientists is panned in the blogosphere, a South Korean newspaper reports that disgraced stem cell scientist Woo Suk Hwang is teaming up with respected researcher Shoukhrat Mitalipov on a new venture to work on cloning mechanisms, the U.S. Department of Energy pulls out of the country's planned first commercial-scale carbon capture and storage plant, and a just-released report details the reasoning behind three judges' decision to acquit six Italian scientists of manslaughter for failing to warn the public of the L'Aquila earthquake. Also, the U.S. Congress pushes for greater protections for farm animals in scientific research. And a "shattered" chromosome cures a woman born with a serious genetic disease.

[Report] Direct kinetic measurement of the reaction of the simplest Criegee intermediate with water vapor

Thu, 2015-02-12 19:00
Carbonyl oxides, or Criegee intermediates, are important transient species formed in the reactions of unsaturated hydrocarbons with ozone. Although direct detection of Criegee intermediates has recently been realized, the main atmospheric sink of Criegee intermediates remains unclear. We report ultraviolet absorption spectroscopic measurements of the lifetime of the simplest Criegee intermediate, CH2OO, at various relative humidity levels up to 85% at 298 kelvin. An extremely fast decay rate of CH2OO was observed at high humidity. The observed quadratic dependence of the decay rate on water concentration implied a predominant reaction with water dimer. On the basis of the water dimer equilibrium constant, the effective rate coefficient of the CH2OO + (H2O)2 reaction was determined to be 6.5 (±0.8) × 10−12 cubic centimeters per second. This work would help modelers to better constrain the atmospheric concentrations of CH2OO. Authors: Wen Chao, Jun-Ting Hsieh, Chun-Hung Chang, Jim Jr-Min Lin

Carbon release from ocean helped end the Ice Age

Wed, 2015-02-11 13:20
A release of carbon dioxide from the deep ocean helped bring an end to the last Ice Age, according to new research. The study shows that carbon stored in an isolated reservoir deep in the Southern Ocean re-connected with the atmosphere, driving a rise in atmospheric CO2 and an increase in global temperatures. The finding gives scientists an insight into how the ocean affects the carbon cycle and climate change.
