Today, I am here to discuss global
warming…
The single greatest
environmental challenge facing this planet.
The earth is warming up faster than anyone
expected. The first seven months of this
year, and the last three decades, were the
warmest since 1895. And the Earth’s
temperature has climbed to the highest point
it has been in the past 15,000 years.
If we act now and further temperature
increases are kept to 1 to 2 degrees
Fahrenheit, the damages – though
significant – will be manageable. But if we
don’t act, and warming increases by 5 to 9
degrees, the damage will be catastrophic
and irreversible.
The Earth has warmed 1 degree in the past
century, and we are now seeing the
dramatic effects:
Oceans are rising; coral reefs are dying;
species are disappearing; glaciers are
melting. Greenland is now losing 20% more
mass than it receives from new snowfall
each year. And it will shrink further as the
planet warms.
Heat waves, droughts, hurricanes and
floods are occurring with greater frequency
and greater intensity. In 2003, heat waves
caused 20,000 deaths in Europe and the number of Category 4 and 5 hurricanes has
doubled since the 1970’s.
If nothing is done…if the Earth warms 5 to
9 degrees Fahrenheit, the face of our planet
will change forever.
The Greenland and Western Antarctic ice
sheets would melt completely. These two
ice sheets currently hold 20 percent of the
Earth’s fresh water.
Sea levels could well rise by 20 feet. Think
about the damage that would cause to
coastal areas around the world.
Additionally, hurricanes, tornadoes and other
severe weather would become more
volatile than ever. Catastrophic wildfires
would more than double as temperatures
spike to well above 100 degrees.
The Earth may be much closer to a tipping
point than science has shown thus far. And
if we move beyond that tipping point,
catastrophe becomes a certainty. You can’t
go back, because the carbon dioxide doesn’t
dissipate. It stays in the atmosphere for five
decades or more. That means the carbon
dioxide produced today will still be in the
atmosphere in 2050 and beyond – causing
the Earth’s temperature to rise. To stabilize
the planet’s climate, we need a 70 percent
reduction in carbon dioxide emissions.
That’s why we must act soon and
decisively. We must act now. Our decision
will impact not only our future, but the
futures of our children and grandchildren.
The question is: what should we do? The largest contributor to global warming
is electricity generation which makes up 33
percent of the problem. Globally, coal
produces 9.3 billion tons of carbon dioxide
every year – or one-third of all global
greenhouse gas emissions. So it’s critical
that we find ways to clean up coal.
The second largest contributor is
transportation which represents 28 percent
of carbon dioxide emissions.
Fundamentally,
there are two ways to reduce these
emissions.
1. Improve the fuel efficiency of vehicles.
2. Move away from oil and gasoline-based
fuels and toward alternatives.
We also need to develop new, clean
technologies and alternative fuels. This
includes the electric plug-in hybrid, bio-fuels,
E-85 using cellulose ethanol, and fuel cells.
A 4 inch by 4 inch fuel cell can power a 30
watt light bulb for 5 years. Thus clean fuel
cells can be used to produce electricity and
hydrogen to fuel our vehicles with no carbon
dioxide emissions.
We also need to become much more
energy efficient. We, as individuals can also
make a difference. Inexpensive solar
panels, carpooling, using energy efficient
light bulbs and appliances, windmills that
can be built in your backyard, and
geothermal energy are other simple
solutions.
These are easy to do, and they can really
make a major difference.
Now is the time to act. The choice is clear.
It is time to stop talking and to begin acting.
Thank you.
