effects of global warming

• Increase of temperature on the earth:
• Changes in temperature increase the frequency and intensity of some severe weather events, like floods, droughts and tornadoes.
• Lower agricultural yields and species extinctions are caused by Global Warming.
• Rise of sea levels:

Sea levels are rising due to thermal expansion of the ocean, along with melting of land ice.
The total power of cyclones has increased noticeably because their average intensity and duration have increased.
