WHAT IS GLOBAL WARMING?

Global Warming is an average increase in the temperature of the atmosphere near the Earth’s surface, oceans, and in the troposphere.

Yesterday Today Tomorrow

DIFFERENCEGLOBAL WARMING

is the increase of the Earth’s average surface temperature due to greenhouse gases and

fossil fuels.

CLIMATE CHANGEis a long-term (at least 30 years) change in climate,

including average temperature and

precipitation.

CAUSES OF GLOBAL WARMING

• Burning of fossil fuels (Coal/Crude Oil)

• Power plants → Generate electricity• from vehicles• Population increase• Deforestation• Agri-business (biofuels, cattle

producing methane)• Too much waste

THE GREENHOUSE EFFECT

Some sunlight that hits the earth is reflected. Some becomes heat.

and other gases in the atmosphere trap (keep) heat, keeping the earth warm.

EFFECTS OF GLOBAL WARMING

SEA LEVEL HAS RISEN BY 1-2 MM

OVER THE LAST 100 YEARS.

MELTING OF GLACIERS.

HEAT WAVES, COLD WAVES, STORMS,

FLOODS AND DROUGHTS.

MORE THAN A MILLION SPECIES OF

WORLDWIDE COULD BE EXTINCT.

POLAR BEARS COULD BE EXTINCT

BY 2050.

INCREASING NUMBER OF MALADIES

SPREAD FROM TROPICAL PLACES.

SOME INTERESTING FACTS OF GLOBAL WARMING.

APPROXIMATELY 600,000 DEATHS OCCURRED AS A RESULT OF WEATHER-RELATED NATURAL DISASTERS IN THE 1990S, WHERE 95 PERCENT OF THOSE DEATHS TOOK PLACE IN DEVELOPING COUNTRIES.

2014 WAS THE WORLD’S HOTTEST YEAR ON RECORD, SURPASSING THE PREVIOUS RECORD SET IN 2010.

THE U.S. PRODUCES 25 PERCENT OF THE CARBON DIOXIDE POLLUTION FROM FOSSIL-FUEL BURNING.

COWS PRODUCE MORE METHANE THAN THE OIL INDUSTRY DOES. 20 PERCENT OF METHANE GAS EMISSIONS IS PRODUCED BY FARMED CATTLE.
