Climate change is happening
I was checking out the EPA Website and I found this article on climate change.
Our Earth is warming. Earth's average temperature has risen
by 1.5°F over the past century, and is projected to rise another 0.5 to 8.6°F
over the next hundred years. Small changes in the average temperature of the
planet can translate to large and potentially dangerous shifts in climate and
weather.
The evidence is clear. Rising global temperatures have been
accompanied by changes in weather and climate. Many places have seen changes in
rainfall, resulting in more floods, droughts, or intense rain, as well as more
frequent and severe heat waves. The planet's oceans and glaciers have also
experienced some big changes - oceans are warming and becoming more acidic, ice
caps are melting, and sea levels are rising. As these and other changes become
more pronounced in the coming decades, they will likely present challenges to
our society and our environment.
