This is my ppt on Global Warming

1. Global Warming

2. What is Global Warming?
• Global warming is the long-term heating of Earth's climate system observed since the pre-industrial
period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which
increases heat-trapping greenhouse gas levels in Earth's atmosphere.
• Global warming is the unusually rapid increase in Earth's average surface temperature over the past
century primarily due to the greenhouse gases released as people burn fossil fuels. ... Temperatures
are certain to go up further. Despite ups and downs from year to year, global average surface
temperature is rising.

3. Causes of Global Warming:
• Oil and Gas. Oil and Gas is used all the time in almost every industry.
• Deforestation. Deforestation is the clearance of woodland and forest, this is either done for the wood or to
create space for farms or ranches. ...
• Waste. ...
• Power Plants. ...
• Oil Drilling. ...
• Transport and Vehicles. ...
• Consumerism. ...
• Farming. ...

4. Greenhouse effect
• The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy
reaches the Earth's atmosphere, some of it is reflected back to space and some is absorbed and re-
radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the
Earth.

6. Greenhouse gases:
• Carbon Dioxide.
• Methane.
• Nitrous Oxide.
• Fluorinated Gases.

7. Deforestation
• Deforestation, the clearing or thinning of forests by humans. Deforestation represents one of the
largest issues in global land use. Estimates of deforestation traditionally are based on the area of
forest cleared for human use, including removal of the trees for wood products and for croplands
and grazing lands.

8. Ways to reduce Global Warming:
• Reduce, Reuse, Recycle. ...
• Reduce Waste. ...
• Upcycle your Furniture. ...
• Recycle your Clothes. ...
• Bring your own Shopping Bags. ...
• Replace Regular Incandescent Light Bulb. ...
• Buy Energy-Efficient Appliances. ...
• Turn Off the Lights.

9. Thank you!
I hope you have learned a lot about Global Warming. I also hope that you might help me and each
citizen of the world protect our precious planet “Earth”. Earth helps us in many ways, so now it is our
chance in turn to help Earth! Thank you so much for learning with me. I hope you had a fun time
learning. Bye! Stay home Stay safe!
