AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS: 

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS Hundreds of millions of Africans and tens of millions of Latin Americans who now have water will have shortages in less than 20 years Death rates for the world’s poor will rise by 2030 as a result of global- warming-related illnesses of malnutrition and diarrhea.

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS: 

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS By 2050, more than 1 billion people in Asia could have water shortages. By 2080, water shortages could threaten 1.1 to 3.2 billion people. Malaria and dengue fever are likely to grow. Europe’s small glaciers will disappear and the large glaciers will shrink dramatically by 2050.

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS: 

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS Half of Europe’s plant species could be on the path to extinction, and becoming endangered, or extinct by 2100. By 2080, between 200 million and 600 million people could be chronically hungry. By 2080, about 100 million people could be flooded by rising seas each year. A small health risk now will be turned into a major health risk as smog in USA cities worsens and ozone-related deaths increase to about 4.5 percent by 2050.

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS: 

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS Polar bears and many other animals living in cold environments now will be pushed to extinction.. All of Europe’s plant species could become endangered, or extinct by 2100.

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS: 

AS GREENHOUSE GASES GROW WORSE, SO WILL THE IMPACTS By 2080, between 200 million and 600 million people could be chronically hungry as a result of global warming effects. At first, more food will be grown in some regions such as Latin America. Regions outside the tropics in the northern latitudes will experience longer growing seasons and healthier forests.

EUROPEAN SEVERE WINDSTORM Deadliest storm to strike the continent since 1999. Hurricane-like winds reach 120 mph Accompanied by extreme precipitation and, in some locations, snow. Over 2 million lose power Business interruption was wide spread Travel canceled or delayed for tens of thousands Losses estimated at over $1 billion

Question: Is the Severe Windstorm of 18 January 2007 another indication of Global Warming?: 

Question: Is the Severe Windstorm of 18 January 2007 another indication of Global Warming?

Answer: Many believe that the answer is probably ”YES.” All nations should take realistic scientific, technical, and political actions to resolve the urgent issues related to the “METRICS OF GREENHOUSE GASES” and the “TIPPIMG SCENARIOS.” :

WHAT FACTORS DRIVE GLOBAL WARMING?: 

WHAT FACTORS DRIVE GLOBAL WARMING?

SOLAR INPUT: 

SOLAR INPUT After hitting Earth's upper atmosphere, a third of the sun's energy is reflected back into space. The two-thirds that gets through the atmosphere drives Earth's weather engine

THE ATMOSPHERE : 

THE ATMOSPHERE “Greenhouse" gases include water vapor, carbon dioxide, methane and nitrous oxide. They trap heat inside the atmosphere. Too much trapped heat increases temperatures on the Earth's surface.

THE OCEANS: 

THE OCEANS Oceans, which cover two-thirds of Earth, are the source of moisture in the air. Oceans store heat efficiently and transport it thousands of miles. The oceans and marine life also consume huge amounts of carbon dioxide.

THE WATER CYCLE: 

THE WATER CYCLE Higher air temperatures can increase water vaporization and melting of ice. Although water vapor is the most potent greenhouse gas, clouds also affect evaporation and create a cooling effect.

CLOUDS: 

CLOUDS Clouds cool Earth by reflecting solar energy. Clouds also warm Earth by trapping the heat being radiated upward from the Earth’s surface.

ICE AND SNOW: 

ICE AND SNOW The whiteness of ice and snow reflects heat outward into space, cooling Planet Earth in the process. When ice melts into the ocean, the ocean water losses heat.

LAND SURFACES: 

LAND SURFACES Mountain ranges can block clouds, creating "dry" shadows downwind. Sloping land facilitates water runoff, leaving the land and air drier.

LAND SURFACES: 

LAND SURFACES A tropical forest will soak up carbon dioxide, but … Once cleared for cattle ranching or community development, the same land can becomes a major source of methane, a greenhouse gas.

HUMAN INFLUENCES : 

HUMAN INFLUENCES Humans appear to be exacerbating warming by adding to the greenhouse gases that are naturally present in the atmosphere, but…. Fuel use by humankind is the chief cause of rising carbon dioxide levels.

HUMAN INFLUENCES : 

HUMAN INFLUENCES On the other hand, humans create temporary, localized cooling effects through the use of aerosols, augmented by smoke and sulfates from industry. These reflect sunlight away from the Earth.
