combustion of fossil fuels such
as coal, oil ong>andong> gas in power

• Greenhouse gases demonstrated in ong>theong> mid-19th
• Increased levels of greenhouse gases must cause
ong>theong> Earth to warm in response.
• Ice cores drawn from Greenlong>andong>, Antarctica, ong>andong>
tropical mountain glaciers show that ong>theong> Earth’s
climate responds to changes in solar output, in
ong>theong> Earth’s orbit, ong>andong> in greenhouse gas levels.
• Most climate scientists agree ong>theong> main cause
of ong>theong> current global warming trend is human
expansion of ong>theong> greenhouse effect.

– carbon dioxide
– nitrous oxide
– chlorofluorocarbons (CFCs)

• More than 90 percent probability that human
activities over ong>theong> past 250 years have
warmed our planet.
• Carbon dioxide levels have raised from 280
parts per million to 379 parts per million in
ong>theong> last 150 years.
CO2 production by humans
• 29 gigatons of CO2 a year
• Atmospheric CO2 is at its highest
level in 15 to 20 million years
• A natural change of 100ppm
normally takes 5,000 to 20,000
years. The recent increase of
100ppm has taken just 120 years.
• Atmospheric concentration of CO2
has increased by 35% since ong>theong>
beginning of ong>theong> age of
The Possible Consequences
• More Precipitation
• Higher Sea Level
• Shifting climate pattern
Carbon Dioxide Concentration
Global Surface Temperature
Arctic Sea Ice
What can we do?
• Individual responses
• Nuclear energy
• Oong>theong>r carbon free energy sources
– solar power
– wind power
• Switching from high-carbon fuels like coal ong>andong> oil, to reducedcarbon
– natural gas
• Carbon sequestration
– Geologic sequestration
• In my opinion ong>theong> best option is for a combination of all of ong>theong>se
• Industry has made ong>theong> stong>andong>ard of living significantly higher but it
has come at a cost that we are now seeing.
• Because with ong>theong> industrial revolution brought about a significant
amount of burning fossil fuels for energy.
• The burning of a hydrocarbon (fossil fuel) produces carbon dioxide.
• This carbon dioxide production has become so significant that it has
led to increased temperatures, higher sea levels, ong>andong> decreasing ice
• If we as a society do not start making some changes it seems as if
ong>theong> problem will only continue to persist ong>andong> worsen.
• While ong>theong>re are some options to help reduce carbon dioxide
emissions such as carbon free energy sources, using more reducedcarbon
fuels, ong>andong> carbon sequestration it seems ong>theong> best option
would to be to use a combination of ong>theong>se while more technology is
