New Enzyme Allows Plants to Grow in Dry and High CO2 Conditions
18 December 2009 | Green News | No Comments
Increasing levels of CO2 in the atmosphere and reduction of water resources are two major problems on our planet. Despite these degradation processes, researchers at the University of California San Diego have discovered some plant enzymes able to solve these two problems simultaneously.
In other words, these special enzymes can allow plants to save water while consuming more carbon dioxide. In this way water resources will be saved and the amount of CO2 in the atmosphere will be reduced.
The Planet’s Future will be Decided in Copenhagen

Over the years, the earth climate has gone through several periods of heating and cooling. All these changes occurred slowly, due to natural factors, but now the earth climate has reached a level where any error caused by humans could be fatal.
The main factor influencing global warming is the greenhouse effect. This phenomenon is caused by human actions, and as scientists say, greenhouse gases in the atmosphere result in reducing the reflection of sunlight. This thing means nothing but excessive heating, so if greenhouse gases indicate a high density then the heating process will be very intense.
Earth’s Climate Could Experience Another Sudden Ice Age

The Earth is very old – about 4.5 billion years and counting. In this time it has experienced numerous events, we humans would call catastrophes, which have brought it to the present shape and form. There is no doubt in the scientists mind that those kinds of events will soon appear again.
Ozone Layer and Air Pollution
28 November 2009 | Green News | 3 Comments
Ozone is concentrated in the stratosphere at an altitude of 15-35 km. It is formed of O2 molecules passing through a photo-dissociation process. In the stratosphere, there is a balance between ozone formation and decomposition processes. Usually this balance is broken by a substance called ChloroFloroMethane coming from aerosols and cooling systems.
CO2 emissions – Produced in 3 ways
25 November 2009 | Green News | No Comments
CO2 released in the atmosphere is nothing but a source of environmental pollution, a factor with a huge role in global warming process. We all know that carbon dioxide is the result of fossil fuel combustion (coal, oil or natural gas). Currently, highest carbon emissions are produced by cars, trucks and non-nuclear power plants. Because of that, urban areas are considered as areas with high concentration of carbon dioxide. To reduce the effects of pollution, carbon dioxide can be captured and stored. Today, carbon dioxide effects on atmosphere is a controversial issue.
