Transcript
Greenhouse gases—water vapor,
carbon, methane, and nitrous oxide—
trap heat in our atmosphere. Those gases are
neither “good” nor “bad.” They are natural.
Think of our atmosphere as a gorgeous crocheted
blanket of gases, that lets in sunshine and
light, and releases just enough heat to keep
temperatures comfortable for human life.
That’s a climate in balance.
For more than a century, humans have been sending
extra greenhouse gases into our atmosphere, from
industrial and agricultural activities. We are tampering
with the balance of gases in our atmosphere. It is now
trapping too much of the sun’s heat, so that our planet
cannot properly cool off. We’re throwing the
regulation mechanisms out of whack.
This has created global warming. Our average
temperatures are climbing steadily, and dangerously.
This is such an enormous change that it is almost
impossible to believe. But there is no disagreement
among serious climate scientists. We are changing
our climate. And we are beginning to see,
feel—and suffer from—the results.
Sure. It has done so for hundreds of
millions of years. But humans weren’t
around to experience those glacial
freezes and epic melts. We couldn’t
have survived.
During our era, the Holocene era,
humanity has enjoyed a fairly stable
climate—and we have flourished
because of that.
Climate scientists can measure the
“fingerprint” of the carbon released by
human activity that is contributing to
warming.
All of our weather is now affected by climate change—
because the environment is warmer and moister than it
used to be. Global warming fuels more intense deluges
from major storms, and rising seal levels make storm
surges more destructive. Warming intensifies droughts
and wildfires. Since 1980 weather disasters in North
America have increased fivefold.
Munich Re, a reinsurance company, put it bluntly:
“Nowhere in the world is the rising number of natural
catastrophes more evident than in North America.”
No one wins with climate change. It is
devastating —
To children—and to everyone’s health: heat
waves are more frequent, more intense, and last
longer, leading to stroke and respiratory problems.
Children’s lungs are more vulnerable to the smog
that is caused by higher temperatures. Insect-borne
illnesses are spreading, and asthma and allergy seasons
are getting longer.
To farmers: Searing droughts of longer than normal
duration are plaguing our Heartland.
To ranchers: More frequent, large scale wildfires are
turning thousands of acres of pasture into infernos
fueled by drier, warmer weather.
To homeowners: destruction of houses and gardens due
to abnormally high winds, and flooding isn’t just a coast
issue—as folks in Vermont and Tennesse well know.
To city dwellers: massive power outages and destruction
of infrastructure due to more severe and frequent
storms. Floods that would normally occur once a
century are now happening every 3 to 20 years.
To wildlife: many species cannot adapt fast
enough to global warming;
they are threatened with extinction.
There are dozens of things you can
do to limit your own contribution to
carbon pollution, from eating less meat
to driving a more fuel-efficient car to
keeping your house well-insulated.
But this problem has to be attacked with
large scale action.
BE AN ENGAGED CITIZEN
There are times when being a good
mom means getting involved. Tell the
President, Congress, your mayor—and
anyone else who will listen—that you are
deeply concerned about climate change,
and they should be too.
BE DEMANDING
Urge President Obama to use his leadership
to convey the urgency of this global disaster
Ask him to issue a Presidential Proclamation:
make America the most energy efficient
nation in the world by 2035.
PROTECT THE CLEAN AIR ACT
Join our campaigns to demand that the
Environmental Protection Agency
reduce greenhouse gas emissions
of carbon, soot, and methane from
all major sources
SUPPORT RENEWABLES
Tell your power company—and your
governor— you want more renewable
energy sources like wind and sunshine
in your electricity mix.
