Climate is the
temperature, humidity, precipitation, winds, radiation, and other meteorological
conditions characteristic of a locality or region over an extended period of
time.
Climate change
is any long-term significant change in the “average weather” that a
given region experiences. Average weather may include average temperature,
precipitation and wind patterns .
The term Global Warming refers to
the observation that the atmosphere near the Earth's surface is warming. This
warming is one of many kinds of climate change that the Earth has gone through
in the past and will continue to go through in the future. It is reasonable to
expect that the Earth should warm as the amount of greenhouse gases in the
atmosphere increases. It is known for certain that atmospheric concentrations of
greenhouse gases are rising dramatically due to human activity. It is less well
known exactly how the increases in these greenhouse gases factor in the observed
changes of the Earth's climate and global temperatures.
The major greenhouse
gases are:
water vapor, which causes about 36–70% of the greenhouse effect on
Earth (not including clouds)
carbon
dioxide, which causes 9–26%
methane,
which causes 4–9%
ozone, which causes 3–7%.
It is not possible to state
that a certain gas causes a certain percentage of the greenhouse effect, because
the influences of the various gases are not additive. (The higher ends of the
ranges quoted are for the gas alone; the lower ends, for the gas counting
overlaps.)
Other greenhouse gases include, but are not limited to, nitrous
oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and
chlorofluorocarbons.
Human beings
can contribute to global warming and climate change by
polluting and cutting down rainforests, but humans can not control the
climate or change it. The climate system is very complex and has many
variables and components. Human beings do not control all the variables
and components or the Planet Earth.
Any
organization or person that is saying things like "we can solve the
climate crisis" or "we can stop global warming" are making
statements that are just "Advertising Slogans" impossible to accomplish.
To actually
"stop global warming" or "solve the climate crisis" human
beings would have the ability to control the following to name a few:
The Sun
Volcanic
Activity
The Weather
The Atmosphere
All Human
Activities
The Oceans
No matter how
aggressively heat-trapping emissions are reduced, some amount of climate change
and resulting impacts will continue. Consequently, there is a need for
adaptation and mitigation.
“Adaptation”
–
improving our ability to cope with or avoid harmful impacts or taking advantage
of newly favorable conditions
Mitigation is
defined as -to lessen in force or intensity, as wrath, grief, harshness, or
pain; moderate- to make less severe. At best human beings can slightly modify
climate change.
“Mitigation”
–
reducing the amount of climate change, for example, by reducing heat-trapping
emissions or increasing their removal from the atmosphere
We should try
to be the best protectors of the planet as much as we are capable and
adapt to and prepare for the changes in the Earth's Climate that are
inevitable.
If we stop all greenhouse gas
emissions, will global climate change stop?
Industrial activity has already
pumped billions of tons of greenhouse gases into the atmosphere, and we have yet
to see the full effect of warming from those gases. A great deal of excess
energy imbalance is stored in the ocean and will be released gradually over
time, continuing to warm the planet.
In other words, some degree of
climate change is irreversible. Scientists call this the "committed
warming," and estimate that the Earth would continue to warm about 1 degree
Fahrenheit (.6 degrees Celsius) even if greenhouse gas levels in the atmosphere
stopped growing immediately. That is, if all human greenhouse gas emissions
stopped tomorrow, the Earth would still warm for at least a half-century.

There are three main factors that directly influence the energy balance
of the earth and it's temperature:
The total energy influx, which depends on the earth's distance
from the sun and on solar activity
The chemical composition of the
atmosphere
Albedo, the ability of the earth's surface to reflect light.
