melting glaciers and stronger storms.
3. Climate Changing
Is the long-term changes in climate, including average temperature
and precipitation.
• It recognize that, although the average surface temperature may
increase.
5. Causes of climate change
CO2 emissions are by far the largest cause of global warming and ocean
acidification, and they are rising.
Methane emissions are the second largest cause of warming, and they are rising.
Since 1950 human activities have led to virtually all temperature rise. Natural
forces have caused virtually none of the temperature rise.
The largest human sources of CO2 emissions are burning fossil fuels, making
cement and burning off gas (“flaring”) from oil and gas production.
6. Changing Effective on environment
• Rising temperature
•Unpredictable weather patterns
•Rising sea levels
• Loss of wildlife and biodiversity
