March 26,University of Minnesota Methane bubbles to the surface Lake Kariba, Africa, of the world's largest man-made lake and reservoir by volume. Christian Dinkel A paper published this week in the journal Limnology and Oceanography Letters is the first to show that lake size and nutrients drive how much greenhouse gases are emitted globally from lakes into the atmosphere.
Although carbon dioxide is the most well-known greenhouse gas, methane and nitrous oxidewhich are also emitted from lakes, could be far more devastating because they have much greater warming potential.
Christian Dinkel Green lakes result from excessive fertilization by nutrients, such as phosphorus and nitrogen, and when sediment accumulates in lakebeds. Such "greening" is called eutrophication. Downing The authors point to four key advancements that enabled their results to be more accurate than previous estimates: Recent advances in satellite and sensor technology, availability of detailed geographical data on lakes, an increasing number of global lake observations and improved statistical survey designs.
The authors also offer some relatively simple things people anywhere can do to protect the water in their community: Decrease fertilizer application on urban and agricultural land Maintain large buffer or filter strips of vegetation that intercept stormwater runoff Manage septic systems to ensure they work effectively Keep streets and curbs clean "Even moderate increases in lake and surface water eutrophication over the next 50 years could be equivalent to adding 13 percent of the effect of the current global fossil fuel emissions," said Downing.The Greenhouse Effect The United States releases twenty tons of carbon monoxide per person per year.
Carbon Monoxide release is a result of burning fossil fuels with an insufficient amount of oxygen that causes the formation of carbon monoxide that pollutes our environment.4/4(1). Sep 27, · A greenhouse stays warm inside, even during winter.
Sunlight shines in and warms the plants and air inside.
But the heat is trapped by the glass and can't escape. Research Papers on the Greenhouse Effect The Greenhouse Effect Research Papers investigate the significant changes it brings to our climate.
Evidence is mounting that, on earth, the “greenhouse effect” is bringing about significant changes in the climate.
The climate of the Earth is profoundly affected by two competing processes: the greenhouse effect, which acts to warm the lower atmosphere and cool the upper atmosphere, and atmospheric convection (thermals, clouds, precipitation) which does just the opposite: cools the lower atmosphere and warms.
Water vapour is the most dominant greenhouse gas. Water vapour is also the dominant positive feedback in our climate system and amplifies any warming caused by changes in atmospheric CO2. This positive feedback is why climate is so sensitive to CO2 warming.
Learn about key greenhouse gases and their sources, as well greenhouse gas emissions at the global, national, facility,and household level.
