"For more than three decades NASA has focused its space-faring skills and science chops CSI-like on an elusive global killer. Later this month, that pursuit takes us to East Asia. In a few years, part way to the moon.
We are getting close.
Air pollution causes an estimated 152,000 deaths a year across the Americas and more than 2 million deaths in the Western Pacific, according to the United Nations. Some parts of the world have a detailed view of local air quality from ground sensor networks and forecast models that generate public alerts. But for much of the world this type of information and warning are not available.
Space offers a tantalizing global solution.
Spacecraft orbiting Earth hundreds or thousands of miles away with instruments to track pollutants – the way weather satellites watch clouds and storms – could benefit people worldwide. And if scientists had the global facts about air pollution and could better unravel the complex ebb and flow and mixing of pollutants from different sources, there would be a more solid scientific foundation for smart strategies to cut air pollution".

Air pollution is a lethal global health hazard. A trio of science and technology projects aims to help.

"A large, ribbon-shaped lake may be hiding beneath the ice that covers Antarctica, and it may contain countless life forms – unlike any others on earth – that have been trapped, undisturbed, in the frozen continent for millions of years".

"Evolution can react surprisingly quickly to climate change -- at least for an important species of earthworms. For seven years, scientists have exposed the natural habitat of Enchytraeidae to a warmer (+0.5 degrees C) and drier climate by ingenious use of curtains. Twelve percent of the genetic changes found in the worms could be directly attributed to the small changes in the soil temperature and moisture".

"A reduction in the amount of oxygen dissolved in the oceans due to climate change is already discernible in some parts of the world and should be evident across large regions of the oceans between 2030 and 2040, according to a new study led by the National Center for Atmospheric Research (NCAR)".

"In a study published today, researchers from the University of Hawai'i at Mānoa (UHM), Rutgers University, and the University of Haifa identified key and novel components of the molecular "toolkit" that allow corals to build their skeletons (called biomineralization) and described when—in the transformation from floating larvae to coral skeleton—these components are used".

"Science can flourish when experts disagree, but in the governmental realm uncertainty can lead to inadequate policy and preparedness. When it comes to climate change, it can be OK for computational models to differ on what future sea levels will be. The same flexibility does not exist for determining the height of a seawall needed to protect people from devastating floods".

"Flaring of waste natural gas from industrial oil fields in the Northern Hemisphere is a potential source of significant amounts of nitrogen dioxide and black carbon to the Arctic, according to a new NASA study.
Nitrogen dioxide is a well-known air pollutant and health hazard, and black carbon, also known as soot, is an agent of global warming that is critical for understanding climate change effects in the Arctic. In addition to absorbing sunlight while aloft, which heats the air, black carbon darkens white snow when it settles on the surface, accelerating snowmelt. The amount of black carbon that reaches the Arctic is currently poorly estimated.
Scientists hadn't found all the sources of black carbon that ends up in the Arctic, a puzzle that was brought to the Goddard group by Joshua Fu, an atmospheric modeler at the University of Tennessee at Knoxville. The atmospheric modeling community, which runs computer simulations of Earth's atmosphere, uses emission inventories reported by governments or compiled by researchers as a starting point for simulating pollution trajectories throughout the atmosphere. However, their results generally underestimated the amount of black carbon reaching the Arctic when compared to direct field measurements, Fu said".

"Rare and somewhat esoteric. These are the huge pyramids of ice that stand proud of the surface on some glaciers.
To date, the phenomenon has only really been seen around the Karakoram mountain region of Pakistan.
The Baltoro glacier, which begins life at the very summit of K2, has some particularly fine examples.
Up to 25m in height and with widths of up to 90m, their triangular shapes when viewed from a distance give the impression of a flotilla of sail boats.
Now, scientists are getting a handle on how these giant "ice sails" form and wither over time, and how the processes involved depend on the special conditions that exist in the Karakoram region".

Scientists describe the processes that drive "ice sails" - a rare and somewhat esoteric feature of debris covered glaciers.

"Scientists have discovered that large areas of intact coral reef with extensive live coral cover, not disturbed by humans or climate change, harbor the greatest amount of genetic diversity. With this work, the researchers uncovered a link between species diversity of an ecosystem and the genetic diversity encoded within the DNA of those species".

"A successful trial has been described of a new method of identifying the carbon uptake of specific marine bacterioplankton taxa. The technique uses proteomics -- the large-scale study of proteins -- to observe directly the metabolic processes of communities of microorganisms".

Scientists and engineers helping save the planet.
Introduction
The Azimuth Project is an international collaboration to create a focal point for scientists and engineers interested in saving the planet. Our goal is to make clearly presented, accurate information on the relevant issues easy to find, and to help people work together on our common problems.  We need your help! 

The Azimuth Project includes a wiki, a blog, and a discussion forum

This Azimuth page here on Google+ lets you keep track of news related to energy, the environment and sustainability.  Posts on this page are written by Rasha Kamel, John Baez, Jim Stuttard, Frederik De Roo and David Tanzer.  The posts reflect the individual authors views and taste; we don't agree about everything!
