Global Warming 101
Global Climate Change
or more correctly,
s
Scientists tell us the
earth is warming !
arctic ice is melting,
putting polar bears at risk
As temperatures rise
extreme weather events
will become more
common
the forest fires in
the West are largely
due to global
climate change
the forest fires in the
American West
are due in a large part to
Global Climate Change
Rainforets sequester (capture)
much of the excess CO2,
But........
the rainforest
is being burned
to make room
for agriculture
or it is being
cut down
for timber
Rainforests capture CO2
but...
The oceans absorb excess CO2,
but...
CO2 causes
the ocean
to become
more acidic
which leads to
coral bleaching
and kills reefs
80% to 90%
of global
warming (heat)
is in the ocean.
Warm water
expands,
causing
flooding in
coastal
cities.

The energy stored is enough to light
nearly 500 100-watt light bulbs for each
of the roughly 6.7 billion people living
on this planet, continuously, for the
16 years of this study~NOAA


What can I do to reduce the effects of
Global Climate Change ?
The difference between
climate and weather is a
measure of time ~ NASA
30 billion tons
of carbon !!
