Many scientifics predict huge natural disasters resulting from increased temperatures in our planet: floods, famine, droughts, freeze, epidemic…will be frequent in all countries.
It is estimated that about 2100 the average temperature of earth’s surface will be between 1.5 and 6 grades higher than in 1980. ¿who are the responsibles and what can we do?
Our planet is getting warmer: that’s a reality. The last ten years have been the hottest; scientifics have announced that in future it would be warmer. And, as always, human beings are the main responsibles: we exert a direct impact over warming process, also known as “greenhouse effect”.
Greenhouse effect is an increase of greenhouse gases concentration: carbon dioxide (CO2), chlorineflourinecarbonate (CFC), methane (CH4), nitrogen oxide (N2O) and troposphere ozone.
In small concentrations these gases are necessary for our survival. Solar energy come in through them, reaches the earth and return as infrared energy. At that moment greenhouse gases catch them and keep the infrared radiation heat, as a greenhouse.
But in major quantities, the main consequence of greenhouse effect is the atmosphere global warming.
Why?...because contaminant gases (or greenhouse), as carbon dioxide, provoke that solar energy keep trapped in atmosphere. And it takes only a slight modification of temperature to break the nature equilibrium.
Sea water will evaporate, in other parts will be torrential rain, floods, hurricanes, droughts, heat waves and freeze…among other natural disasters.
An important concern
According to different scientific studies, supported by ONU, it is estimated that in 2100m average temperature of earth will be between 1,5 and 6 grades higher than in 1980. Temperatures are increasing at global scale, and the recorded 15 hottest years have been since 1980.
This is the main concern of scientifics, because besides all the aforementioned disasters it could be famine and epidemic, ice floes melting, flora and fauna disappearing and Caribbean Island flooding.
What is worse is that we are “collaborating” with global warming by using fossil fuel (coal, oil and its derivates as paraffin, liquefied gas and benzine), allowing industrial contamination, among others, and forests and wet lands destruction.
It is believed that if temperature continues to elevate, global warming is going to uneven distributed. Continental zones are going to be hottest than sea zones.
Globalwarming awareness2007 is a global campaign to let people know about the causes and negative effects of global warming over our planet. |
