Global Warming
Global
warming is one of the most serious challenges facing us today. To protect the
health and economic well-being of current and future generations, we must
reduce our emissions of heat-trapping gases by using the technology, know-how,
and practical solutions already at our disposal.
Tropical
deforestation is the largest source of emissions for many developing countries,
but slowing deforestation can’t solve the climate problem by itself. As
forest-rich developing countries step up to take responsibility for reducing
their emissions, all industrialized nations should not only support their
efforts but, most importantly, reduce their own emissions and lead efforts to
avert dangerous climate change.
For
years we have heard so much about the causes of climate change, that we’ve
missed the fact that there are simple, practical solutions that can slow this
growing problem. Technologies exist today that can cut emissions of
heat-trapping gases and make a real difference in the health of our planet. And
these solutions will be good for our economy, reduce our dependence on foreign
oil, and enhance our energy security.
Global
warming doesn’t just mean balmy February days in northern climes. It also means
increasingly hot days in the summer, and a host of negative impacts that are
already under way and are expected to intensify in the
coming decades.
coming decades.
-More heat waves will likely increase the
risk of heat-related illnesses and deaths.
-Cities and towns along the nation’s
major rivers will experience more severe and frequent flooding.
-Some areas will likely experience more
extensive and prolonged droughts.
-Some of our favorite coastal and
low-lying vacation areas, such as parts of the Florida Keys and Cape Cod, will
be much less appealing as sea levels rise, dunes erode, and the areas become
more vulnerable to coastal storms.
-Many families and businesses, who have
made their living from fishing, farming, and tourism could lose their
livelihoods, and others who love hunting, boating, skiing, birdwatching, and
just relaxing near lakes, streams, and wetlands will see some of their favorite
places irretrievably changed.
The
solutions to climate change are here and it’s time we put them to use. If we
get started today we can tackle this problem and decrease the unpleasant
outcomes that await us if we do nothing. The steps we need to take are common
sense. And, more often than not, they will save consumers money. The cost of
inaction, however, is unacceptably high.
The
scientific consensus is in. Our planet is warming, and we are helping make it
happen by adding more heat-trapping gases, primarily carbon dioxide (CO2), to
the atmosphere. The burning of fossil fuel (oil, coal, and natural gas) alone
accounts for about 75 percent of annual CO2 emissions from human activities.
Deforestation—the cutting and burning of forests that trap and store
carbon—accounts for about another 20 percent.
Procrastination
is not an option. Scientists agree that if we wait 10, 20, or 50 years, the
problem will be much more difficult to address and the consequences for us will
be that much more serious.
We’re
treating our atmosphere like we once did our rivers. We used to dump waste
thoughtlessly into our waterways, believing that they were infinite in their
capacity to hold rubbish. But when entire fisheries were poisoned and rivers
began to catch fire, we realized what a horrible mistake that was.
Our
atmosphere has limits too. CO2 remains in the atmosphere for about 100 years.
The longer we keep polluting, the longer it will take to recover and the more
irreversible damage will be done.
Fuel-efficient
vehicles. Renewable energy. Protecting threatened forests. These common sense
solutions won’t only reduce global warming, many will save us money and create
new business opportunities.
Best
of all, these solutions exist now. We just need to insist that business and
government take the necessary steps to make them available and affordable. Then
we have to let consumers know what to do and provide incentives to help all of
us make better choices.
The
following five sensible steps are available today and can have an enormous
impact on the problem CO2 remains in the atmosphere for about 100 years.
