Climate Change – What Is It?

Climate change is an amazingly simple phrase for such a complex
subject. Following, we have a go at defining climate change in today’s
terms.
Climate Change – What is it?
In the current day lexicon of scientists, climate modification isn’t
really a term of use anymore. The reason for this is that we have come
to understand that the effect of the changes we make to our environment
will increase the temperature in many locations on the planet, but will
also cool a few places. In light of this, the thing you know of as
climate modification is actually referred to as global climate change.
Over all, however, the world is definitely warming.
We need a simple definition for climate change in relation to the
warming of the planet, one that gets the gist without excluding the
simplicities. The simplest and most accurate definition is that climate
change is the effect greenhouse gases have on the earth’s climate.
Greenhouse gases include, but are not limited to, carbon dioxide and
methane. While this sounds like a simple definition, there are a couple
of key things to realize.
First, climate change is both a natural phenomena and one created by
man. Put another way, greenhouse gases are a natural part of the
biosphere and would exist if man did not. Indeed, they are a critical
component to the existence of life on this planet. If greenhouse gases
didn’t exist, the temperature on planet earth would average zero
degrees! Naturally occurring gases, however, keep the temperature at a
much more livable 59 degrees.
So, if climate change occurs naturally, what is the big panic about?
The problem we are facing is the volume of greenhouse gases in the
atmosphere. These gases act as thermal blankets for the atmosphere. The
more gas in the atmosphere, the thicker the blanket and the less heat
escapes. Over the last 80 years, we have been pumping massive amounts
of greenhouse gases into the sky. At the same time, we have been
reducing forestation around the planet, the primary plant collection
that sucks greenhouse gases out of the atmosphere. This double whammy
is starting to show negative results, the increased heating of our
world.
The ultimate question with climate alteration is what will happen as
the planet heats up. We are already seeing signs with the retreat of
the glaciers. Glacier National Park, for instance, is going to have to
be renamed since it has already lost 65 percent of all of its glaciers!
While the exact end result of these environmental changes is not clear,
we can expect major climatic changes over the next 80 years.
