Greenhouse effect.



We owe this much interested in?

Clearly, if these are the most important des:
 The melting of glaciers, melting of snow early and severe droughts will cause more water shortages in the western United States.
 Rising sea levels cause coastal flooding on the Eastern seaboard, Florida and other areas like the Gulf of Mexico.
• Forests, farms and cities will face troublesome new pests and more mosquito-borne diseases.
• Disruption of habitats such as coral reefs and alpine meadows could drive many species to extinction of plants and animals.

What causes global warming?



Carbon dioxide and other air pollutants accumulate in the atmosphere forming a layer growing thicker, trapping the sun's heat and causingglobal warmingThe main source of contamination by carbon dioxide emissions are power generation plants based on coal, then emit 2.500million tons per year. The second leading cause, are cars emit
about 1.500 million tons of CO2 per year.

How can we reduce pollution?

It's simple: By reducing pollution from vehicles and power plantsWe immediately generalize the use of existing technologies to producecleaner cars and power generators more modern. We can start using renewable energy sources like wind, solar and geothermal. And we can manufacture more efficient appliances and conserve energy.
 

Cap of ozone.

The cap this of ozone increasingly debilitated because of the climate change.

That is the climate change.

It's called climate change to climate change with respect to climate history to a global or regional scale. Such changes occur at very different scales of time and all themeteorological parameters: temperature, atmospheric pressure, precipitation, cloudiness, etc.. In theory, are due to both natural causes (Crowley and North, 1988)and anthropogenic (Oreskes, 2004).
The term is often used in inappropriately, to refer only to the climatic changes thathappen in the present, using it as a synonym for global warming. The United Nations Framework Convention on Climate Change uses the term only to refer climatechange due to human causes:
"Climate change" means a change of climate attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.

Got another planet where you can go?

We are al ready in time.

Optimistic vision of the world.
