What Is Global Warming?

Global warming is thewarming of the earth

through carbon dioxide(CO2 being !um!ed intothe atmos!here fromtail!i!es and smo"estac"s#$hen the gases tra! heat

What*s +a!!ening

,cientists say that the barrier

insulating the continental ice

ca!s is melting#

%$he im!acts of warmingtem!eratures in Antarctica

are li"ely to occur first in the

northern sections of the

continent- where summer

tem!eratures a!!roach the

melting !oint of water- .2

What*s +a!!ening

As the ice melts- big chun"s

of glaciers will brea" off and

become li"e ice cubes in a big

glass of water# $he icechun"s- "nown as icebergs-

create mass in the ocean# $he

icebergs dis!lace the water

causing the ocean le)el to

rise# ,ome of the shoreline in

many !laces li"e /lorida

(where the land is at a low

altitude will go under water#

What Will +a!!en

“Rising global temperatures areexpected to raise sea level, andchange precipitation and other

local climate conditions.Changing regional climate couldalter forests, crop yields, andwater supplies. It could also affecthuman health, animals, and manytypes of ecosystems. Desertsmay expand into existing

rangelands, and features of someof our national parks may bepermanently altered.http!""yosemite.epa.gov"oar"globalwarming.nsf"content"impacts.html

+ow 1ong +as It Been Going

On$he reason the tem!erature has risen

so much in the !ast 30 years is

because of how much more we ha)e

used fossil fuels- which gi)es off

carbon dioxide# %According toNOAA, the global warmingrate in the last 25 years hasrisen to 3.6 degrees F percentury, which tends to

confirm the predictions oftemperature increases madeby international panels ofclimate scientists !"##$.%http&''www.world(iewofgloba

What*s +a!!ening to the

Animals%Coral reef bleaching- the whitening of di)erse

in)ertebrate taxa- results from the loss of

symbiotic 4ooxantheallae andor a reduction in

!hotosynthetic !igment concentrations in

4ooxanthellae residing within scleractiniancorals# Coral reef bleaching is caused by

)arious anthro!ogenic and natural )ariations in

the reef en)ironment including sea

tem!erature- solar irradiance- sedimentation-

xenobiotics- subaerial ex!osure- inorganic

nutrients- freshwater dilution- and e!i4ootics#

Coral bleaching e)ents ha)e been increasing in

both fre5uency and extent worldwide in the !ast 20 years# Global climate change may !lay

a role in the increase in coral bleaching e)ents-

and could cause the destruction of ma6or reef

tracts and the extinction of many coral

s!ecies#&

Conclusion

Global warming is affecting !lants- animals- humans and the

earth# We need to learn how to conser)e our use of fossil fuels

to minimi4e carbon dioxide !roduction# $his will slow downthe effects of global warming#
