1.Global warming is the result of an increase in the earth’s average surface temperature due to greenhouse gases
like carbon dioxide and methane. These gases are required for the presence of human life on earth. However,
global warming is happening due to over-emittance of these gases.
2.According to IPCC 2007 report, sea levels will rise by 7-23 inches by the end of
this century due to global warming.
3.Since 1880, the average temperature has risen by 1.4-Fahrenheit degrees.
4.The last two decades of the 20th century have been hottest in the last 400 years, according to climate studies.
5.The is one of the worst places to be affected by global warming.
6. The Arctic ice is melting rapidly. By 2040 the region is expected to have a completely ice-free summer,
or even earlier.
7. The Montana Glacier National Park has only 25 glaciers instead of 150 that were there in the year 1910.
8.Due to global warming and pollution, coral reefs are suffering the worst bleaching with the highest dying
record since 1980.
9.Global warming that is causing extreme weather changes has shown its implications in the way of
forest fires, heat waves and severe tropical storms throughout the world.
10.There has been a tremendous increase in water vapor, carbon dioxide, methane nitrous oxide and especially
greenhouse gases due to polluting substances emitted as a result of industrialization, pollution, deforestation.
11.More than 1 million species have become extinct due to disappearing habitats, ecosystems acidic oceans all
caused due to global warming.
12.The global warming will completely alter the ocean’s conveyer belt which will cause a mini ice age in Europe.
13. 2000-2009 has been the hottest decade periods of the earth.
14.The rate at which carbon dioxide is being dumped into the environment is 1000 tons per second until
the 2011 records.
15.Human activities release around 37 billion metric tons of carbon dioxide per year.
16.By the year 2100, the average temperature will rise by 5.8 degrees as a result of global warming.
17.A failure in preventing global warming can cause a major economic collapse causing 20% of global
domestic output to fix.
18. Global warming can lead to massive food and water shortages and has a life-threatening impact on wildlife.
19.Between 2000-2100, the heat-related deaths will rise by 150,000.
20. In the last 30 years, the average consumption of fossil fuel by the United States has been 80%. Fossil fuels are the most dangerous contributors to global warming.
