Meaning of global warming
Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.
The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further
Causes of global warming1. Carbon dioxide
emissions from fossil fuel burning power plants
2. Carbon dioxide emissions from burning gasoline for transportation
3. Methane emissions from animals, agriculture such as rice paddies, and from Arctic seabeds
4. Deforestation, especially tropical forests for wood, pulp, and farmland
5. Global Warming Cause: Increase in usage of chemical fertilizers on croplands
Effects of global warming• Rise in sea levels worldwide
•More killer storms
Massive crop failures
Widespread extinction of species
Disappearance of coral reefs
Changes in insect pests: Climate change can affect the number and kinds of pests directly. It can also affect them by changing the mix of plant varieties and their nutrient content. This can influence
plant survival, food chains, and the spread of disease.
The general retreat of mountain glaciers during the past century is one example of
evidence that the climate is changing
Control measures of global warming
Use Public Transport
Use Renewable Energy Like Wind Power
Burn Methane
Use Smart Cooler, Heater & Air Conditioner
Tune up and maintain vehicles properly
Clean the air in your house
Reduce electricity usage to the
maximum
Prefer recycling
