Warm water colects in one
place, evaporation and clouds
buildup may increase. Marine
organisms consume huge
amount of CO2
The Water Cycle
When evaporation its
formed leads to cloud
formation, which can have
a cooling effect
Clouds
By reflecting solar energy and
warm Earth by up trapping heat
being radiated up from the
surface
The Atmosphere
Gases give Earth a temperature.
Green-houses gases, watervapor, CO2,
and other gases absorb heat energy, then
re-rediate a portion of it back on the
surface
Ice and Snow
Bright white expansive of ice and snow
reflect sunlight back into space, cooling
the planet. Melting sea ice draws heat
from the ocean
Solar Input
Solar energy having travelled
miles, hits the upper
atmosphere. The rest warms
Earth and fueld it´s weather
engine
Land Surface
When solar energy penetrates the land
surface it is converted into heat, most of
which radiates upward. And it can have
major effects on climate.
Human Influences
The green-house gases, the
fuel combustion and the
aerosols are the main
human activities magnify
warming effects
Global Temperatura Rising
Earth´s surface has risen ahalf
degree Celsius in the last past
century. Dips and Spikes reflect
natural fluctations and
short-term events.
Green-house effect
The atmosphere, only a fraction of that heat makes it
directly back into space. Therest is trapped in the lower air
layers, which contain a number of gases, that absorb the
outgoing infrared radiation. As does gases heat up, some
of their warmth radiates back down the surface. With
increased heating more evaporation, this creates a
powerful feed backloop.
Models and Uncertainty
The general circulation models consist of
equations representing the laws of the
atmospheric physics and ocean circulation
Missing CO2
Oceans
Serve as a vast "sink" for CO2. The oceans
apparently remove at least 2 billion tons frmo
the atmosphere each year
Clouds
Clouds shade Earth´s surface, promoting cooling, but
depending on their altitude, density, and other conditions, they
can also trap outgoing heat, promoting warming
Human Activity
We releases aprox. 7
billion metric tons of CO2
every year.
As the World Warms
Warming of the magnitude anticipated by the IPCC cloud also
prompt widespread calamity. For one thing, it would putmore water
vapor into air. Causing more more rainfall worldwide and probably
more intense weather generally. The most probable effect is that the
averge amount of precipitation in any given event will be greater
