Produce in the International Space station grow in a greenhouse named Lada after the Russian goddess of spring.
#Efforts to curb climate change require greater emphasis on livestockwhile climate change negotiators struggle to agree on ways to reduce carbon dioxide (CO2) emissions they have paid inadequate attention to other greenhouse gases associated with livestock according to an analysis
A reduction in non-CO2 greenhouse gases will be required to abate climate change the researchers said.
and the United states reached their conclusions on the basis of a synthesis of scientific knowledge on greenhouse gases climate change and food and environmental issues.
We also need to reduce non-CO2 greenhouse gases to lessen the likelihood of us crossing this climatic threshold.#
#Methane is the second most abundant greenhouse gas and a recent report estimated that in the United states methane releases from all sources could be much higher than previously thought.
By reflecting the latest estimates of greenhouse gas emissions on the basis of a life-cycle

Although CO2 is the most abundant greenhouse gas the international community could achieve a more rapid reduction in the causes of global warming by lowering methane emissions through a reduction in the number of ruminants the authors said than by cutting CO2 alone.
In addition to reducing direct methane emissions from ruminants cutting ruminant numbers would deliver a significant reduction in the greenhouse gas emissions associated with the production of feed crops for livestock they added.#

and nature and that it is imperative to tackle the drivers of climate change namely greenhouse gases.
One way to slow climate change is to increase the number of trees On earth as they through photosynthesis take up the greenhouse gas carbon dioxide converting it to carbon products
There is a great need to reduce the amount of greenhouse gasses in the atmosphere. Our approach exemplifies how strategies to do this can be targeted to optimize feasibility
and the amount of greenhouse gases they produce. The study produced by scientists at the International Livestock Research Institute (ILRI) the Commonwealth Scientific and Industrial Research Organisation (CSIRO)
and beef and greenhouse gas emissions vary widely depending on the animal involved and the quality of its diet.
Greenhouse gas emissionsscientists also sought to calculate the amount of greenhouse gases livestock are releasing into the atmosphere
and the amount of greenhouse gases released for every kilo of protein produced something known as emission intensity.
and environmental risks notably greenhouse gases produced by the energy and transport services needed for industrial livestock production
For example the low livestock feed efficiencies and high greenhouse gas emission intensities in Sub-saharan africa are determined largely by the fact that most animals in this region continue to subsist largely on vegetation inedible by humans especially by grazing on marginal lands
Climate change due to unabated greenhouse-gas emissions within our century is likely to put 40 percent more people at risk of absolute water scarcity than would be without climate change a new study shows by using an unprecedented number of impact models.

Another paper co-authored by Dr Gosling shows that without reductions in global greenhouse-gas emissions 40 per cent more people are likely to be at risk of absolute water scarcity than would be the case without climate change.
while river flooding could decrease by the end of the century across about a third of the globe increases are expected at more than half of the areas investigated under a high greenhouse gas emissions scenario.
Given the present trajectory of greenhouse gas emissions agricultural models estimate that climate change will directly reduce food production from maize soybeans wheat and rice by as much as 43 percent by the end of the 21st century.
which makes up 15 percent of the global greenhouse gas emissions. Both food security and urbanization is on the program for next year's major international conference on sustainability hosted by the IARU partnership.

The EMF27 study shows that without policies to cut greenhouse gas emissions fossil fuels will remain the major energy source in 2100 with resulting increases in greenhouse gas emissions.
These papers touch on issues as diverse as climate policy land use and agriculture and non-CO2 greenhouse gases among others.
However our study which compares long-term scenario results across a large suite of technologically-detailed models shows that fossil resource constraints are unlikely to limit greenhouse gas emissions in this century.
because in preliminary greenhouse experiments they showed varying degrees of salmonella resistance said Max Teplitski a UF associate professor of soil and water science.
Particularly in the context of the crisis-stricken honeybee populations the buff-tailed bumblebee Bombus terrestris is being bred on an industrial scale for the pollination of fruit and vegetable crops both inside and outside greenhouses.
when they were introduced first into central Chile in southern South america in 1998 as pollinators in a few greenhouses with the backing and approval of the state authorities.
But in the greenhouse they did not stay. Some individuals escaped and very soon they established colonies in the wild.
Such a scenario could involve including snow cover/albedo in existing greenhouse gas exchanges like the Kyoto protocol or a cap-and-trade program or ecosystem services market in
These are three more or less optimistic pathways 5 for change in greenhouse gas concentrations from now until the end of the 21st century.
'Scenario RCP8. 5 is an extreme scenario with a major increase in greenhouse gases. The most optimistic scenario (RCP2. 6) corresponds to virtuous behavior with very low greenhouse gas emissions.

Trees are the lungs of the earth for that they can fix CO2--the major greenhouse gas--more efficiently.
They found that one in every three European cities has no plans on the table to reduce greenhouse gas emissions
How cities respond to climate change is important as they are responsible for 31 to 80 percent of global greenhouse gas emissions.
and renewable energy generation to reduce greenhouse gas emissions. Overall 130 cities (65 percent) have at least a mitigation plan and less than a third (28 percent) also an adaptation plan.
and also set quantitative targets to reduce greenhouse gas emissions. Most (88 percent) mitigation plans quantify targets for carbon dioxide or greenhouse gas emission reduction.
Countries vary in their planning: 93 percent of UK cities studied have a mitigation plan
#Preindustrial rise in greenhouse gases had natural and anthropogenic causesfor years scientists have argued intensely over
None of them alone proved sufficient for explaining the greenhouse gas increase. When he developed his own model combining characteristics of both the natural and anthropogenic hypotheses it agreed closely with the ice core data.
and greenhouse gases extending as far back as 1. 5 million years almost twice as old as the oldest ice core drilled to date.
By studying the past climate scientists can understand better how temperature responds to changes in greenhouse-gas concentrations in the atmosphere.
A 3. 2-km-long ice core drilled almost a decade ago at Dome Concordia (Dome C) in Antarctica revealed 800000 years of climate history showing that greenhouse gases
Climate scientists suspect greenhouse gases played a role in forcing this transition but they need to drill into the ice to confirm their suspicions.
The information on greenhouse-gas concentrations at that time can only be gained from an Antarctic ice core covering the last 1. 5 million years.
Activities associated with agriculture are currently responsible for just under one third of greenhouse gas emissions;
The species is found almost in every urban center in the tropics as well as in greenhouses and other humanmade structures in cool temperature climates.
If severe enough the loss of rainforest could cause the release of large volumes of the greenhouse gas carbon dioxide into the atmosphere.
Even under future scenarios in which atmospheric greenhouse gases rise dramatically the models project the dry season in the southern Amazon to be only a few to 10 days longer by the end of the century
The researchers say the most likely explanation for the lengthening dry season in the southern Amazon in recent decades is caused human greenhouse warming
The Amazon rainforest normally removes the greenhouse gas carbon dioxide from the atmosphere but during a severe drought in 2005 it released 1 petagram of carbon (about one-tenth of annual human emissions) to the atmosphere.
Greenhouse gas balances depend on utilisation formsit can thus be said that straw can contribute to the future energy mix.
The degree to which it will contribute to greenhouse gas reduction however will depend on how the straw is used.
The different greenhouse gas balances cast a differentiated light on the EU's goal of covering ten percent of transportation sector's energy use by using biofuels.
Although a greenhouse gas and pollutant carbon dioxide also is a plant nutrient. Had Earth's terrestrial ecosystems remained a carbon source they would have generated
We have completed already some experiments both in protected greenhouses and in open fields working in close contact with local farmers said Egamberdieva who is engaged also in promotion campaigns with the government and in outreach campaigns among farmers.
#Biochar in soils cuts greenhouse gas emissionsuniversity of TÃ bingen microbiologists show soil microbe communities can be influenced to decrease nitrous oxide emissions.
they also present a new possibility for reducing greenhouse gas emissions worldwide. Biochar is produced by high-temperature thermochemical decomposition of organic material a process known as pyrolysis.

The research team took into account the sources of electricity used to charge the electric vehicles in evaluating greenhouse gas emissions.
Electricity produced from hydroelectric sources--more common in the northwest United states--dramatically reduced total greenhouse gas emissions for electric vehicles operated there.
In every state in the U s. electric trucks provided some reduction in greenhouse gas emissions with urban routes providing the most advantage.
In about half of the states the electric trucks cut greenhouse gas emissions by a third

#Chinas synthetic gas plants would be powered greenhouse giantscoal synthetic natural gas plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants
If all nine plants planned by the Chinese government were built they would emit 21 billion tons of carbon dioxide over a typical 40-year lifetime seven times the greenhouse gas that would be emitted by traditional natural gas plants Jackson said.
if the gas produced by the new plants is used to generate electricity the total lifecycle greenhouse gas emissions would be 36 percent to 82 percent higher than pulverized coal-fired power.
If the synthetic natural gas made by the plants were used to fuel vehicles the lifecycle greenhouse gas emissions would be twice as large as from gasoline-fueled vehicles.
The increased carbon dioxide emissions from the nine government-approved plants alone will more than cancel out all of the reductions in greenhouse gas emissions from China's recent investments in wind
It will lock in high greenhouse gas emissions water use and mercury pollution for decades. Perhaps there's still time to stop it.
But Decicco pointed out that a recent National Academy of Sciences report concluded that the Renewable Fuel Standard may not reduce greenhouse gas emissions at all once global impacts are counted.
#Plant community plays key role in controlling greenhouse gas emissions from carbon rich moorlandsdifferent moorland plants particularly heather
and cotton grass can strongly influence climate warming effects on greenhouse gas emissions researchers from Lancaster University The University of Manchester
But the study found that the make-up of the plant community could also play a key role in controlling greenhouse gas emissions from these carbon rich ecosystems as not all vegetation types respond in the same way to warming.
when heather was present warming increased the amount of CO2 taken up from the atmosphere making the ecosystem a greater sink for this greenhouse gas.
or climate change itself also had such a strong impact on greenhouse gas emissions and even changed the way that warming affected them.
Setting up this experiment allowed us to test how greenhouse gas emissions are affected by a combination of changes in climate and changes in plant communities.
The team performed the experiments in a greenhouse and on outdoor nursery pads using soil moisture sensors to maintain soil water content above specific thresholds.
Greenhouse studies were conducted at the University of Georgia in Athens while the nursery studies took place at the University of Georgia Horticulture Farm in Watkinsville
We found that plant growth increased with increasing water content threshold in both greenhouse and nursery settings the authors said.
Kenya's leadership in adaptation planning is particularly important he added given that international negotiations to mitigate the effect of climate change by reducing greenhouse gas emissions are basically at a stand still.
and greenhouse gas emissions of products and services The doctoral thesis broadened the scope of previous analyses by focusing on new environmental impacts:
Only a few production paths contribute to greenhouse gas emissionsanother surprising observation was that out of tens of thousands of different production paths only a handful had very significant environmental impacts.
For example with respect to greenhouse gas emissions only 0. 3 per cent of the variables examined were relevant.
As this result surprised the researchers the method was tested by trying to predict Finland's greenhouse gas emissions in 2005 from year 2002 data only updating the 60 most important components of the 23000 model parameters.
grass used for livestock feed has enormous potential to reduce greenhouse gas emissions. Referred to as biological nitrification inhibition
Nitrous oxide is the most powerful and aggressive greenhouse gas with a global warming potential 300 times that of carbon dioxide.
Nitrous oxide makes up about 38 percent of all greenhouse gas emissions in agriculture which accounts for almost a third of total emissions worldwide said Michael Peters who leads research on forages at the Colombia-based International Center for Tropical agriculture (CIAT
but it also contributes about half of agriculture's greenhouse gas emissions Peters explained. BNI is a rare triple-win technology that's good for rural livelihoods as well as the global environment and climate.

and plays an important role for the water and carbon balance including greenhouse gases. Even though it was clear that major problems were occurring in Mongolia in the past 20 years researchers were uncertain
#Increased greenhouse gases and aerosols have similar effects on rainfallalthough greenhouse gases and aerosols have very distinct properties their effects on spatial patterns of rainfall change are surprisingly similar according to new research from the University of Hawaii at Manoa's International Pacific Research center (IPRC) and Scripps Institution of Oceanography.
Humanmade climate change comes mostly from the radiative forcing of greenhouse gases and air pollutants or aerosols.
While greenhouse gases are mixed well in the atmosphere and tend to be distributed evenly around the globe aerosols vary greatly in local concentration
Even though aerosols and greenhouse gases are concentrated in vastly different regions of Earth all three models revealed similar regional effects on rainfall over the ocean.
The result means that it is hard to tell apart the greenhouse and aerosol effects. The scientists noted that both aerosol-induced
and greenhouse-gas-induced changes in rainfall appear to be mediated by the spatial patterns of sea surface temperature.
The climate changes induced by greenhouse gases and by aerosols share a common set of ocean-atmospheric feedback structures explaining the spatial resemblance between the two types of response.
while reducing pollution and greenhouse gases will require more than luck. Odds are it will take a daring out of the box idea like this one.
#Beetles modify emissions of greenhouse gases from cow patscattle contribute to global warming by burping
and farting large amounts of greenhouse gases. Some of the same gases are emitted also from cow pats on pastures.
But now researchers from the University of Helsinki have found that beetles living in cow pats may reduce emissions of the key greenhouse gas--methane.
Agriculture is one of the biggest sources of the anthropogenic greenhouse gases responsible for global warming.
and private industry that supports research on technologies that significantly reduce emissions of greenhouse gases while meeting the world's energy needs.
and Geospace Sciences We can easily measure the greenhouse gas budget from a single smokestack but somewhat less well for a stand of trees.
whether we can explain and model greenhouse gas distribution. In the study the scientists compared the recent aircraft data with aircraft data gathered from 1958 to 1961 using U s. Air force weather reconnaissance flights.
If we want to stabilize the climate system we need to focus on greenhouse gases such as carbon dioxide nitrous oxide and methane.
The model also incorporates greenhouse gases and pollutants that can result from those activities. Earlier studies of short-lived climate pollutants did not use an integrated dynamic model such as GCAM.
which includes substantially reducing all greenhouse gas emissions instead of only limiting carbon dioxide as the previous short-lived climate pollutant studies did for their comparative scenario.
While focusing on reducing all greenhouse gas emissions including methane the comprehensive climate policy scenario also reduced the amount of soot in the atmosphere.
however the focus needs to be on carbon dioxide and other greenhouse gases. The Environmental protection agency funded this research.
Dr Vanessa Adams says that late dry season wildfires in Australia's tropical north generate about 3%of the country's annual greenhouse gas emissions so strategic burning could be an important abatement activity.
which are greenhouse gases from warming the atmosphere and also disrupting atmospheric circulation. had taken these effects hold they would have combined to shift rainfall patterns in ways beyond those that may already be happening due to rising carbon dioxide in the air.
and industrial greenhouse gases--have pushed together the jet stream in the southern hemisphere south over recent decades.
The projected stopping of the poleward jet migration is a result of the ozone hole closing canceling the effect of increasing greenhouse gases.
As a greenhouse gas CFCS can be thousands of times more potent than carbon dioxide. Dutch scientist Guus Velders estimated in a 2007 study that had the chemicals not been phased out by 2010 they would have generated the warming equivalent of more than 220 billion tons of carbon dioxide.
While HFCS are ozone-safe they too are powerful greenhouse gases that have become a concern as world leaders grapple with climate change.
The Kyoto Protocol was drafted to regulate global greenhouse gas emissions but its expiration at the end of 2012 has led some countries to seek climate protections from the Montreal Protocol.
It's a lesson surely for our current efforts to limit greenhouse gas emissions. Story Source:
