Global warming is caused by increased levels of greenhouse gases like carbon dioxide from human activities such as burning fossil fuels and deforestation. These gases trap heat in the atmosphere and cause the planet to warm over time. Some effects of global warming include rising sea levels, more severe wildfires, intensifying heat waves, and increased extreme weather events. To help address global warming, people can reduce fossil fuel usage and energy consumption, plant trees to absorb carbon dioxide, and decrease waste production.

1. GLOBAL WARMING

2. History Of Earth’s Climate
• Earth formed ~ 4.6 billion years ago.
• Originally hot.
• Sun’s energy output only 70% of present.
• Liquid water present ~ 4.3 billon year.

3. What Is Global Warming?
• Global warming is the
increase of earth’s average
surface temperature due to
effect of greenhouse gasses,
such as carbon dioxide
emissions from burning fossil
fuels are from deforestation,
which trap heat that would
otherwise escape from Earth.

4. Green House Gases
• A greenhouse gas (sometimes
abbreviated GHG) is a gas in an
atmosphere that absorbs and
emits radiation within the
thermal infrared range . This
process is the fundamental
cause of the greenhouse effect
. The primary greenhouse
gases in the Earth’s
atmosphere are : Carbon
Dioxide ,Methane , Ozone
e.t.c.

5. The Effects Of Global Warming
• Accelerating Sea Level Rise and
Increased Coastal Flooding.
• Longer and More Damaging
Wildfire Seasons.
• More Frequent and Intense Heat
Waves.
• An Increase in Extreme Weather
Events.

6. What Are People Doing to Stop Global
Warming?
• Reduce fossil fuel use and
use less energy.
• Planting tress and other
plants can slow or stop
global warming.
• Reduce waste.
Decomposing waste in
landfills produce methane
and other greenhouse
gases.
