Climate change is the single greatest threat facing our planet. The debate
is over, and the scientific jury is in: global climate change is real, it is
caused mainly by emissions released from burning fossil fuels and it poses
a catastrophic threat to the long-term longevity of our planet. If we do
nothing, the planet will heat up five to ten degrees Fahrenheit by the end
of this century. That would cause enough sea level rise from melting
glaciers to put cities like New York and Miami underwater – along with more
frequent asthma attacks, higher food prices, insufficient drinking water
and more infectious diseases.
The debate is over. The vast majority of the scientific community has spoken
. Climate change is real, it is caused by human activity, and it is already
causing devastating harm here in the United States, and to people all around
the globe. So what are we going to do about it? We will act boldly to move
our energy system away from fossil fuels, toward energy efficiency and
sustainable energy sources like wind, solar, and geothermal because we have
a moral responsibility to leave our kids a planet that is healthy and
habitable. |
