Slowing climate change by targeting gases other than carbon dioxide - 0 views

  •  
    Carbon dioxide remains the undisputed king of recent climate change, but other greenhouse gases measurably contribute to the problem. A new study, conducted by NOAA scientists and published online today in Nature, shows that cutting emissions of those other gases could slow changes in climate that are expected in the future.

Global warming caused by greenhouse gases delays natural patterns of glaciation - 0 views

  •  
    Unprecedented levels of greenhouse gases in the Earth's atmosphere are disrupting normal patterns of glaciation, according to a study co-authored by a University of Florida researcher and published online Jan. 8 in Nature Geoscience.

Gases drawn into smog particles stay there, study reveals - 0 views

  •  
    Airborne gases get sucked into stubborn smog particles from which they cannot escape, according to findings by UC Irvine and other researchers published today in the Proceedings of the National Academy of Sciences.

Nanotechnology points the way to greener pastures - 0 views

  •  
    Nourishing crops with synthetic ammonia (NH3) fertilizers has increasingly pushed agricultural yields higher, but such productivity comes at a price. Over-application of this chemical can build up nitrate ion (NO3-) concentrations in the soil -- a potential groundwater poison and food source for harmful algal blooms. Furthermore, industrial manufacturing of ammonia is an energy-intensive process that contributes significantly to atmospheric greenhouse gases.

Study finds a better way to gauge the climate costs of land use changes - 0 views

  •  
    Those making land use decisions to reduce the harmful effects of climate change have focused almost exclusively on greenhouse gases - analyzing, for example, how much carbon dioxide is released when a forest is cleared to grow crops. A new study in Nature Climate Change aims to present a more complete picture - to incorporate other characteristics of ecosystems that also influence climate.

Aerosols affect climate more than satellite estimates predict - 0 views

  •  
    Aerosol particles, including soot and sulfur dioxide from burning fossil fuels, essentially mask the effects of greenhouse gases and are at the heart of the biggest uncertainty in climate change prediction. New research from the University of Michigan shows that satellite-based projections of aerosols' effect on Earth's climate significantly underestimate their impacts.

Getting to Mars means stopping, landing - 0 views

  •  
    The Challenger and Columbia space shuttle disasters were perhaps two of the most prominent reminders of how crucial it is that everything work just right for a spacecraft to travel to space and successfully return back to Earth. Whether it was the failure of the seal used to stop hot gases from seeping through, or a piece of foam insulation that damaged the thermal protection system, scientists and engineers must make thousands of predictions of all the things that could go wrong during flight.

A surprise: China's energy consumption will stabilize - 1 views

  •  
    Along with China's rise as a world economic power have come a rapid climb in energy use and a related boost in man-made carbon dioxide emissions. In fact, China overtook the United States in 2007 as the world's leading emitter of greenhouse gases. Yet according to this new forecast, the steeply rising curve of energy demand in China will begin to moderate between 2030 and 2035 and flatten thereafter. There will come a time-within the next two decades-when the number of people in China acquiring cars, larger homes, and other accouterments of industrialized societies will peak. It's a phenomenon known as saturation. "Once nearly every household owns a refrigerator, a washing machine, air conditioners and other appliances, and once housing area per capita has stabilized, per household electricity growth will slow,'' Levine explains.

Soil microbes accelerate global warming - 0 views

  •  
    More carbon dioxide in the atmosphere causes soil to release the potent greenhouse gases methane and nitrous oxide, new research published in this week's edition of Nature reveals. "This feedback to our changing atmosphere means that nature is not as efficient in slowing global warming as we previously thought," said Dr Kees Jan van Groenigen, Research Fellow at the Botany department at the School of Natural Sciences, Trinity College Dublin, and lead author of the study.
