4. Greenhouse gases continue to build up in the atmosphere.
5. George Hambley believes that global warming will do good rather than harm to the earth.
Researchers say these changes are having severe effects on animals such as penguins, seals and polar bears. Changes in temperature and wetness in the air can also affect the reproduction of some reptiles and amphibians. For example, the sex of baby painted turtles is linked to the average temperature in July. Scientists say even small temperature increases can threaten the production of male turtles. In Europe, scientists say warmer temperatures are affecting the spring and autumn seasons.
What’s worse, the glaciers (冰川) of the South Pole are beginning to crack (破裂).
The sea level to rise.
Tsunami (海啸)
Tornados (飓风)

An energy source is “renewable” when supplies of it never run out and “non-renewable” when one day they will run out. Which energy sources on your list are renewable and which are non-renewable?
What are fossil fuels?
• Fossil fuels are Ancient animal and plant material below the surface of the earth with a high carbon content, such as coal, oil and natural gas, which can be burnt to produce energy. They are also known as non-renewable energy because once they aபைடு நூலகம்e run out of /run out, they cannot be renewed.
