Adding to our naturalsupply of
greenhouse gases.
The gases can stay in the atmosphere for at least 50 yearsand up to centuries.
The result?
the globe
has heated up by about one degree Fahrenheit over the past century.
One degree not a big deal?
Consider this…
the difference in global average temperatures between modern times
and the last ice age
was only about
9 DEGREES FAHRENHEIT.
ChinaAmerica is the #1 global
warming polluter in the
world.
DISAPPEARING
Arctic ice is rapidly
Polar bears and indigenous cultures are already suffering from the sea-ice loss.
Glaciers and mountain snows are rapidly melting
Glaciers and mountains
areslowly melting.
Coral reefs
which are highly sensitive to small changes in water temperature
Suffered the worst bleaching-or die-off in response to stress- ever
recorded in 1998
We only have one beautiful planet
Earth.
And we are all affected And we are
allbeing affected.
