Global warming is a very real issue that is
often avoided by many.
evidence of global warming exist in plenty.
Surprisingly, groups of people are trying
to turn a blind eye towards the fact that
Earth is getting warmer, and this warming
is threatening our basic existence.
4. How Does it Work?
5. Greenhouse Gases(GHG’s)
Gases in an atmosphere that absorbs and emits radiation within the
thermal infrared range. This process is the fundamental cause of the
Carbon dioxide (CO2)- due to burning fossil fuels.
Nitrous oxide (NO2)- released in great quantities by large
amounts of nitrogen fertilizer on crops and it is also a by-product of
Methane is a combustible gas, and it is the main component of
natural gas, occurs naturally through the decomposition of organic
material and is often encountered in the form of "swamp gas”.
Water vapor- most abundant greenhouse gas, result of climate
changes, eventually condense into clouds which is more able to
reflect incoming radiation. This allows less energy to reach earth’s
surface and heat it up.
6. How Do We Know?
Global warming has been observed and measured by
using thermastatic records and satellite images.
Documents temperature increases over the past century.
Thermostatic records- Scientists have been recording data
of the natural world for hundreds of years. Recordings,
include changes in temperature, sea level, snow cover over
the northern hemisphere etc.
Satellite images- document temperature increases by
observing the earth through satellite imaging. Temperatures
are recoded on graphs and changes are used to monitor the
7. How do we Stop it?
8. Global warming cannot be
Global warming will continue for centuries
due to the long natural processes.
There are changes we can make to decrease the effects.
Cut down on the use of Green house gases.
The electricity that operates many of the devices in our homes
comes from a power plant, and most power plants burn fossil
fuels to generate that power.
9. How we can Slow Global
Use less energy, turn off power when not in use.
Replace incandescent light bulbs with fluorescent bulbs,
which use less energy and last longer.
Substitute high voltage power, fan instead of air
Keep automobile tuned up to prevent harmful fuels to
Recycle garbage and refrain from burning trash.
Plant trees to cut down on carbon dioxide and increase
the release of oxygen.
10. Going Green!
Hydro-electric power, solar power, hydrogen engines and
fuel cells are alternate energy sources that do not
produce fossil fuels.
Cleaning chemicals are also being substituted with
natural products which are less harmful to the
