Atmospheric Carbon Dioxide Fraction Remained Constant In The Last 150 Years, Study Reveals
2 January 2010 | Green News | 4 Comments
The whole “carbon dioxide” puzzle is a lot more complicated matter than most scientist tend to think. Many new research that surfaced lately come to disprove most of their paradigms about this greenhouse gas. It represents about 0.04% of the Earth’s atmosphere but it is a vital gas for the Planet well-being. A major part of the carbon dioxide emitted through human activity does not remain in the atmosphere, but it is absorbed by the oceans and by the Earth’s ecosystems. Less than half, 45 percent, of the CO2 amount still lingers in the atmosphere. Also a new study comes now to show that for the last 150 years, the carbon dioxide fraction has not risen at all.
CO2 Emissions Could Generate Noise Pollution in the Oceans

Since CO2 emissions started to grow, researchers have begun to warn us of the seriousness of this process, using different scientific discoveries related to negative effects of carbon dioxide. Last days, some researchers at the University of Hawaii have discovered that along with the increasing level of CO2 emissions, increases the acidity of the oceans and seas too. When ocean acidity increases, sound-absorbing chemical reactions are reduced and that means the sound will spread in the water faster and noisier.
Third of Plants and Animals could Disappear due to Global Warming

Global warming is a phenomenon that can affect us, humans, but at the same time also can affect many plants and animals. Things that are happening currently on the planet are not simple at all. Researchers have realized about the seriousness of things and announced that a large number of animals and plants should migrate to North to prevent global warming effects. Unfortunately third of these animals and plants, can not migrate at high altitudes and this is a serious problem.
Excessive Irrigation has led to a Decrease in Monsoon Rainfall in Northern India
28 December 2009 | Green News | 1 Comment
Human actions on the environment and generally all land-use decisions can drastically influence climate change. Recently, a scientist from Purdue University have proved that these actions have affected Indian monsoon rains. His research shows that in the last 50 years monsoon rainfall decreased dramatically in rural areas because irrigation was excessively used to increase agriculture. “In the rural areas, we’re seeing premonsoon greening occurring two weeks earlier than what it did 20 years back as the demand for agricultural intensification to feed India’s people increases”.
Black Soot Could Be The Cause Of Melting Himalayas

The Himalayas are the highest mountain system on the Planet. Home to more than 10,000 glaciers and with over 100 peaks, each exceeding heights of 7,200 m, the Himalayas are , even if surprisingly for some, also the place where one of the Earth’s largest fresh water resource is located, being third only after the North and South Poles. It is dependent to the life of so many people and if were to be polluted in any way it would bring hazard to many countries. Some new research suggest that the cause of the melting Himalayas could be just that: pollution.
