CLIMATE CHANGE

 

Building on a foundation, some facts
scientists that global climate is
be significantly altered and the
this century, as a result of increased
greenhouse gas concentrations
such as carbon dioxide, methane,
nitrous oxide and chlorofluorocar bons.

These gases are trapping a portion
growing terrestrial infrared radiation
and is expected to increase the temperature
planet between 1.5 and 4.5 ° C (the so-called
Greenhouse or Global Warming).
In response to this, it is estimated that
global rainfall patterns and
also alter ocean currents.

Although there is general agreement on
these findings, a large
uncertainty about the magnitudes
and rates of these changes on scales
regional and world must do
this group asking them to work from
home in this sense that all together
As I said we all you are right
but to understand the increasing
global temperature must first be
understand how global climate works

 

The climate is the result of the link
between the atmosphere, oceans,
ice sheets (cryosphere), agencies
living (biosphere) and soils
sediments and rocks (geosphere). Only by
considers the climate system under this
vision is possible to understand the flow
matter and energy in the atmosphere and
finally understand the causes of change
global.

This requires analyzing
each of the compartments
interrelated, we start with the most
important to the atmosphere.

The large amount of gas emissions
greenhouse effect has caused an increase
the temperature of the Earth
negative consequences for
evolution of the planet and living beings.

Rising sea levels, expanding
of desertification , declining water
drinking, multiplication of droughts, etc.
The climate has always varied, the problem
climate change in the last
century the pace of these changes has
abnormally accelerated to such an extent
affecting and planetary life. To the
find the cause of this acceleration,
scientists found that there
a direct relationship between the warming
or global climate change and rising
emissions of greenhouse
gases (GHGs), mainly caused
by industrialized societies.

A phenomenon that worries the world, the
global warming and its direct effect
climate change, which occupies much
the efforts of the scientific community
international study and
control, because, they say, puts in
risk the future of humanity.

Why so worried? Highlights
Scientists agree that the increase
the concentration of greenhouse
gases in the Earth's atmosphere
causing changes in climate.

Also agree that emissions
greenhouse gases (GHGs) have been very
intense from the Revolution
Industrial, time after which the
human action on nature
became intense, the greenhouse effect is a
natural phenomenon that makes life in the
Earth. It is caused by a number of gases
found in the atmosphere,
causing some of the heat of the sun
our planet reflects entrapment
keeping the global average temperature
+15 ° C, pro-life,
instead of -18 ° C, which would be
harmful for many millions of years,
the natural greenhouse effect maintained.

Earth's climate at an average temperature
relatively stable and allowed to
develop life. Greenhouse gases
retained the sun's heat near the
earth's surface, helping the
evaporation of surface water for
form clouds, which return the
water to the Earth in a life cycle that is
had kept in balance.

For about 160,000 years, Earth had
two terms in which temperatures
overall average was about 5 °
Celsius lower current. The
change was slow, it took several
thousands of years to get out of the ice age.

Now, however, concentrations of
greenhouse gases in the atmosphere are
growing rapidly and these potentials
changes, there will be great changes in the
global ecosystems.

The negotiators of the new climate pact, which
replace the Kyoto Protocol will need to incorporate
more countries and industrialized nations make
undertake to provide for more stringent goals
carbon emission reduction

Commit to a "real effort" to reduce
emissions, not to acquire millions of AAUs and credits
compensation to meet Kyoto but aligned with the
science and be able to drag the negotiations
international climate agreement capable of up to
tackling climate change, to curb emissions
carbon
