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
