Nitrous Oxide’s Global Warming Impact No Laughing Matterby BC Upham on Tuesday, Apr 6th, 2010 ShareClick to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Google+ (Opens in new window)Click to email this to a friend (Opens in new window)Click to print (Opens in new window)Thawing permafrost in the Northern Hemisphere releases “large amounts” of greenhouse gas nitrous oxide, according to a new study from the journal Nature Geoscience.The study found that under certain conditions thawed permafrost can release as much nitrous oxide as tropical forests, one of the main sources of the gas.Nitrous oxide, also known as “laughing gas,” is ranked third behind carbon dioxide and methane in contributing to global warming, and is regulated under the Kyoto Protocols. According to the EPA, the gas is 310 times more effective in trapping heat than carbon dioxide. Sixty percent of the nitrous in the atmosphere is produced naturally. Global warming “wild card”Twenty-five percent of the land surface in the Northern Hemisphere is underlain by permafrost, and as it thaws it could create a feedback loop that accelerates global warming, because it releases greenhouse gases, like methane and carbon dioxide, which in turn increase warming, spurring more thawing.Scientists had thought only a little nitrous oxide was released during this process, but the journal study suggests otherwise.Scientist Bo Elberling led the study, which was conducted on permafrost core samples from Greenland. Thawing and draining the soil from the cores did not increase the production of nitrous oxide, but when the scientists re-saturated the samples with meltwater from the frozen soil — as would happen naturally after thawing — nitrous oxide production was increased 20 times, with a third of it entering the atmosphere.

To make money. Al Gore is spending so much time and his own money in studying, researching, and campaigning for global warming awareness. So you should ask yourself, who benefits most from scamming us? The people promoting global warming awareness? Or the people who want us to keep polluting, being wasteful and consuming lots of energy and oil?? I think those people want us to keep spending money and increasing our energy consumption so that they make more money. But, that is just my opinion… No, it’s a scam. You are forgetting how much Al Gore and the environmentalists make scamming people about global warming. These environmentalists are making money off a) the government and b) selling solar panels and other worthless “green” energy sources. Meanwhile the people who “want us to keep polluting” are being hurt by ridiculous government regulation. Humans only account for 0.28% of the greenhouse effect, and whatever small warming that causes is offset by the reflective particles that are also being added to the atmosphere during production, which keep small amounts of sunlight from getting to the earth and thus lower temperatures by about the same miniscule amount that our emissions raise it. We need to spend money on real problems. what an idiotic thing to say LOLAl Gore is pulling a funny prank on us all! hope so the government of each nation will help to reduce global warming by undertaking several measures Over population is not as much an issue as what the population consumes is. Earth provides enough for everyone’s need but not enough for everyone’s greed. The root cause of world hunger, ravaging environmental catastrophe and climate change, mass species extinction and global depletion is animal agriculture. animal-sourced food production generates more than 50% of human-caused greenhouse gases, far greater than all the transport(only 13%) in the world and any other human caused contributing factor combined.Methane and Nitrous oxide are as significant,if not more than carbon that can be addressed immediately due to their short half-life, a significant impact could be made to slowing or reversing climate change by reducing methane combined with reducing CO2 caused by livestock. It is simple to do this and it can be done virtually overnight if people understood. Eating local and driving a hybrid reduces your carbon footprint by only 5%. Eating plant based foods or a vegan diet reduces your carbon footprint by an astonishing 95%! Go Vegan and make a huge impact for the better. Eating a plant based diet also drastically reduces your chances of diseases by 95%. Eating a plant based diet saves wildlife and habitats for wildlife, rain forests, huge amounts of water and energy resources.The moral and ethical imperative is not to eat less of what it is bad for us and cruel for the animals as well as destructive to the planet, it is simply not debatable, it is a moral wrong just like slavery, rape or child molestation and it most not be condoned or encouraged in any way.This absurdity of “eat less meat” is a conformist and absurd rational to continuing the horrible practice.Eat less flesh and mammary secretions, is like saying have less slaves, rape less, molest children less. Eating animals is a social evil that must be abolished, it is wrong to devour other living feeling beings who are born into a life of oppression and exploitation and systematically mass murdered to satisfy gluttonous appetites and by doing so grave we rip grave consequences that plague humans with disease and ravage the Earth, nature and the environment. http://www.dulabab.com/climate-change/methane/ Comments are closed.
