Atmospheric Carbon Dioxide Fraction Remained Constant In The Last 150 Years, Study Reveals
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 palnts 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.
Human Blood to Help Capture CO2 Emissions
Biological systems have always been used to develop new technologies, and have proved to be very effective in different activity areas. Today, a New Jersey company is trying to reproduce a similar system in order to capture more efficiently carbon dioxide emissions.
Researchers started from the idea that in our body, the blood contains an enzyme able to capture two pounds of CO2 every day and convert it into bicarbonate. Then, when we exhale, the same enzyme converts the rezulted biocarbonate back into CO2.
How to Capture CO2 Emissions
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.
Audi Efficiency Challenge – Low Emissions, Low Fuel Consumption
Audi recently announced that they want to make an experiment to show once again the efficiency of their models over a distance of 4182 kilometers. The purpose of these experiments is to show that Audi products (Audi cars) are most effective if we talk about emissions and fuel consumption. This experiment is called “Audi Efficiency Challenge from A to B“, and will be presented to a group of 120 journalists, to show them that CO2 emissions and fuel consumption can achieve an ideal rate on 4182 km distance.
New Hummer H3E, Probably The Best Hybrid Car in America
In European countries and many countries of Asia we know the most popular hybrid car manufacturers. But despite these statistics, America has its own creations, very effective car models and very popular hybrid models.
Green News – Exxon To Invest $600M Into Algae-Based Biofuels
Finally some green tendencies from oil companies. Despite opposing for years the idea of renewable energy, the oil giant Exxon Mobile Corporation, with a 2008 revenue of $442.9 billion and the distinction of “the most profitable company in the world” acquireing $45.2 billion last year, announced a $600M “injection” into algae-based biofuel research.
Metro Bilbao Subway Running on Renewable Energy
Spain seems to be among the countries with the most important green projects, projects that are necessary to save energy and reduce CO2 emissions.What Actually Biofuels Are?
The mankind has used biomass fuels for heating and cooking since the discovery of fire.Biofuels can appeared as solid, liquid, or gas fuel.Liquid biofuels have been used since the early days of the car industry.By burning biofuels in a furnace, steam is produced which can drive turbines to drive an electric generator.
The discovery and use of fossil fuels like coal, gas and oil, have dramatically reduced the amount of biomass fuel used in the developed world for transport, heat and power.However, biofuels are axpanding recently in all over the world as providing an alternative to imported oil, because they reduce greenhouse gas emissions and increase energy security by providing an alternative to fossil fuels as in automotive transport and in gas turbine.As energy source in developed countries biofuel contribute about 15% of world’s energy requirements.
Biofuels can be produced from any carbon source that can be replenished rapidly as vegetable matter produced by agriculture and forests or from waste materials obtained from industry, commerce and residential homes, including agricultural waste as sugar cane, straw and chicken litter.Biomass is material derived from recently living organisms.It includes plants, animals, and their byproducts.Garden waste and corp residuel are all sources of biomass.By allowing fermentation in landfill sites or in special anaerobic tanks is also possible to produce methane rich gas to be used in gas turbines.
Biofuels are a renewable energy source based on the carbon cycle.Agricultural products specifically grown for biofuel production include corn and soybeans, wheat, sugar beet, sugar cane and palm oil.Biodegradable outputs from industry, agriculture, forestry and households can be used for biofuel production.
Biofuels and other forms of renewable energy aim to be carbon neutral.Therefore, the carbon released during the use of the fuel, through burning to power transport or generate electrical energy is reabsorbed and balanced by the carbon absorbed by new plant growth.Carbon neutral fuels lead to no net increase in atmospheric CO2 which means that global warming does not increase by this process.
Using waste biomass to produce energy can reduce the use of fossil fuels.Simultaneously reduce greenhouse gas emission and reduce pollution.In industrialized countries, biofuels are producing up 5% of electrical energy requirements.
