New information provides sustainable options for greenhouse operations - 0 views

  •  
    Containers made from plastics are used in most traditional greenhouse operations. While plastic containers are practical, strong, and can be formed to any size, shape, or color, the extensive use of these petroleum-based containers creates significant waste disposal problems for the greenhouse industry and consumers. One example: a 2008 report found that a typical greenhouse operation in California discards over 3560 pounds of plastic trays, flats, and containers annually.

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.

Natural gas can play major role in greenhouse gas reduction - 0 views

  •  
    Natural gas is important in many sectors of the economy: for generating electricity, as a heat source for industry and buildings, and in chemical feedstock. Given the abundance of natural gas available through large global resources and the recent emergence of substantial unconventional supplies in the United States, worldwide usage of the fuel is likely to continue to grow considerably and contribute to significant reductions of greenhouse gas emissions for decades to come, according to a comprehensive, multidisciplinary study carried out over the last three years by MIT researchers.

Experimenting with the effects of climate change on mountain pastures - 0 views

  •  
    "What will a warmer, drier climate do to the legendary quality of Swiss cheese? To address this and other questions, researchers from EPFL and Agroscope Changins-Wädenswil had small flocks of sheep graze below plastic greenhouse tunnels in western Switzerland, near Yverdon. The main focus of the experiment was to study the effects of droughts on mountain pastures and their forage production. On Wednesday, September 12th, the organizers are holding an open day to present the campaign to members of agricultural institutions, researchers and the public."

Economic incentives could massively reduce deforestation emissions in Indonesia, yield ... - 0 views

  •  
    Indonesia has the potential to realize major reductions in national greenhouse gas emissions from deforestation, and simultaneously earn significant new income for national and regional governments, if policies to Reduce Emissions from Deforestation and forest Degradation (REDD+) are developed with strong and specific economic incentives, said scientists in a new paper published in the leading scientific journal 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: Biodegradable products may be bad for the environment - 0 views

  •  
    Research from North Carolina State University shows that so-called biodegradable products are likely doing more harm than good in landfills, because they are releasing a powerful greenhouse gas as they break down.

Study finds greenhouse gas reduction strategy may be safe for soil animals - 0 views

  •  
    A new study has found that an emerging tool for combating climate change may cause less harm to some soil animals than initial studies suggested.

Global warming: New study challenges carbon benchmark - 0 views

  •  
    The ability of forests, plants and soil to suck carbon dioxide (CO2) from the air has been under-estimated, according to a study on Wednesday that challenges a benchmark for calculating the greenhouse-gas problem.

Researchers find a price on carbon could benefit farmers - 0 views

  •  
    Scientists at UQ, in collaboration with JCU, may have found a way to offset up to 2.5 percent of Australia's annual greenhouse gas emissions and secure economic benefits for regional communities.

Studies give growers tools to bring new tropical plant to Indiana - 1 views

  •  
    Purdue University researchers have developed a set of propagation and production protocols that will help Indiana greenhouse growers bring a tropical plant into flower for spring sales.

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.

UCLA climate study predicts dramatic loss in local snowfall - 0 views

  •  
    "The projected snow loss, a result of climate change, could get even worse by the end of the 21st century, depending on how the world reacts. Sustained action to reduce global greenhouse gas emissions could keep annual average snowfall levels steady after mid-century, but if emissions continue unabated, the study predicts that snowfall in Southern California mountains will be two-thirds less by the year 2100 than it was in the years leading up to 2000."

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.

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.

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.

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.
