Global warming is the increase of the earth's average temperature due to release of greenhouse gases like carbon dioxide and methane produced by human pollution. This causes the breakdown of icebergs and increases chances of floods and tsunamis. Greenhouse gases are emitted through activities like burning fossil fuels for energy and transportation and trap heat in the atmosphere, changing the climate. Both human activities like fossil fuel use and natural processes like methane release contribute to global warming and its effects like rising sea levels, more extreme weather, and species extinction. Preventing global warming requires individual actions like using less energy and driving less as well as global solutions like transitioning to renewable energy.

2. Lets start with the word
GLOBAL WARMING
It is the increase of the earth's average
temperature due to release of green
house gases produced in the
atmosphere.
Affects
Breakdown of huge icebergs due to
change in temperatures.
High chances of floods and tsunamis.

3. What actually happens?
Causes
Greenhouse gases like CO2 and methane are produced by
the atmosphere through pollution . Then these greenhouse
gases absorb heat and heat the atmosphere.

4. Green house gases
A greenhouse gas is a gas in an
atmosphere that absorbs
and emits radiant energy within
the thermal infrared range. This process
is the fundamental cause of
the greenhouse effect. The primary
greenhouse gases in Earth's
atmosphere are water vapor, carbon
dioxide, methane, nitrous oxide,
and ozone. Without greenhouse gases, the
average temperature of Earth's
surface would be about −18 °C , rather
than the present average of 15 °C

5. It starts from your own house
Many of our daily activities cause emissions of
greenhouse gases. For example, we produce
greenhouse gas emissions from burning
gasoline when we drive, burning oil or gas for
home heating, or using electricity generated
from coal, natural gas, and oil. Greenhouse
gas emissions vary among individuals
depending on a person's location, habits, and
personal choices.

7. causes
There are 2 different types of causes.
Man made and natural

8. Man made causes
Man-made causes probably do the most damage to our
planet There are many man made causes of global warming.
Pollution is one of the biggest man-made problems. Pollution
comes in many shapes and sizes. Burning fossil fuels is one
thing that causes pollution. Fossil fuels are fuels made of
organic.
Matter such as coal, or oil. When fossil fuels are burned they
give off a green house gas called CO2. When you dig up the
fossil fuels you dig up the methane as well letting it escape
into the atmosphere.

9. Natural causes
Natural causes are causes that are created by nature.
One natural cause is a release of methane gas from
arctic tundra and wetlands. Methane is a greenhouse
gas and a very dangerous gas to our environment. A
greenhouse gas is a gas that traps heat in the earth's
atmosphere. Another natural cause is that the earth
goes through a cycle of climate change. This climate
change usually lasts about 40,000 years.

10. What are the affects
• Climate change
• Increase in sea level
• High chances of flood and tsunamis
• High chances of submerging of lands
• Extinction of species
• Too high temperatures
• Risk of UV rays.

11. Facts
• It is occurring since ice age
• Effecting began with the industrial revolution
• The Arctic is one of the worst places to be
effected by global warming

12. Facts
• The Montana Glacier National Park has only 25
glaciers instead of 150 that were there in the year
1910
• Due to global warming and pollution, coral reefs are
suffering the worst bleaching with the highest dying
record since 1980.
• :The rate at which carbon dioxide is being dumped in
to the environment is 1000 tons per second until the
2011 records.

13. Facts about climate change
• 97 percent: The percentage of scientists who agree that warming trends
over the past century are very likely caused by human activity.
• 1950: Year when atmospheric CO2 levels broke records from the previous
400,000 years, sharply rising and continuing to grow.
• 8 inches: Rise in global sea levels over the last century. The rate of rise has
nearly doubled in the last two decades.
• 16: Number of record-breaking hottest years since 2000. 2016 was the
hottest year yet.
• 1.5 degrees: The average worldwide temperature increase in Fahrenheit
compared to a century ago.
• 400 parts per million: Average concentration since 2016 of CO2 in the
atmosphere, compared to 275 PPM for past 400,000 years.
• 19th century: When the heat-trapping nature of CO2 was first
demonstrated.
• 30 percent: The increase in acidity of the world's oceans.

14. How to prevent global warming?
• 1. Replace Regular Incandescent Light bulb
• 2. Drive Less or Carpool
• 3. Reduce, Reuse, Recycle
• 4. Go Solar
• 5. Buy Energy-Efficient Appliances
• 6. Reduce Waste
• 7. Plant a Tree
• 8.Use Clean Fuel
• 9.Stop Idling Your Car
• 10.Take Lunch in a Tupperware
