Warming Causes Plants To Release Gases That May Mitigate Global WarmingPlants could help cool down the warming world through their own climate change response according to a new study. Trees and other plants are known to emit volatile organic compounds in response to stress--heck they even make noise--but it's unclear whether this affects the environment.Some aerosols--small atmospheric particles--can contribute to cooling because they help form clouds which reflect sunlight. The albedo effect from increased cloud cover contributes to cooler temperatures. But the role of plant aerosols in this process was not well understood. To investigate this Finnish researchers collected data from forests in 11 locations around Earth. They measured aerosol concentrations plant gases average temperatures and the height of something called the boundary layer which is where aerosols and atmospheric gases mix together.They found that plant emissions do impact climate warming but only by a tiny degree. Globally enhanced plant emissions counter about 1 percent of global warming. In forested areas where plants are concentrated the effect is a more meaningful 30 percent however. That could mean heavily treed areas--like the boreal forests of Canada Siberia and Finland--could warm up more slowly than heavily populated areas in more southerly latitudes.The exact ramifications of plant emissions are still incredibly complex but the researchers point out that theirs is the first study to quantify it at all. In estimates of anthropogenic climate change and the effects of aerosol-related air quality directives the response of the biosphere has to be considered they write. Their paper is published this week in Nature Geoscience.[via ScienceDaily]The majority of the data points are from 2008 and prior.
The maximum length of the study is for 14 years in a single location.
Over 80% of the location data is less then two years and some are just a single season.. . . Maybe need a wee bit more data points to draw hypothesis let alone a conclusion?@Kond: It's certainly not too early to formulate a testable hypothesis.  It's all part of the scientific process: first make some observations (they did that); then formulate a testable hypothesis based on those observations; next test that hypothesis. Repeat until you have developed a more robust theory.Until the reason for spraying chemtrails throughout the entire globe is resolved I will believe nothing about this so-called global warming. I see this spraying happening in many different countries in Europe/Asia/Africa/Middle East and the entire USA. I spent two years in Long Beach CA USA and watched every winter season when there should have been rain coming ashore that this spraying started. Results of the spraying: No rain as it should have come ashore normally. Now that nation is facing another drought for their summer season. I see it as that the public will have to turn to the government again for assistance just like those that want control of the USA want. Higher food prices and certain foods no longer available and now there is talk of privatizing the nations water supply. When will the people of the USA just look up and see for themselves that their nation is under attack by those in public office that allow for this spraying to go on daily. The day is soon to be upon us when a certain chemical is sprayed and the entire world will get sick with millions dying. Then watch the governments of the globe along with a pharm company come up with a cure. Now that is going to bring in trillions for that same handful that have already stolen hundreds of trillions. I point this out to many and talk about it all the time but so sad to say that only two out of hundreds will lift their head and question what those ugly streaks are and then take the time to make a search on the Internet for themselves. If some of you do that that don't know what I am talking about then you will know why I won't believe this global warming crap until this chemtrail spraying is resolved.Decay of plant matter is a major sources of so-called greenhouse gas emissions such as methane or carbon dioxide. I would also like to hear the author's explanation of why AGW proponents claim the US has been experiencing climate warming for the past 150 years while the amount of forest acreage in the US has greatly increased during that same period? This would seem to directly contradict the claims made in his article.Great! Maybe it'll make up for an acre of ice disappearing from the poles. Now we only have to make up for the other millions of acres!i thought that we already knew this.its called gaia theory.correct me if am wrong
