2007 IPCC Report on Climate Change
"
Warming of the climate system is unequivocal
, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level
.”
"Most of the observed increase in globally averaged temperatures since the mid-20th century is
very likely due to the observed increase in anthropogenic greenhouse gas concentrations. Discernible human influences
now extend to other aspects of climate, including ocean warming, continental-average temperatures, temperature extremes, and wind patterns."

Great Barrier Reef
25 million years old
1,400 miles long, with 2,900 individual reefs and 1,050 islands. Contained
more biodiversity than all of Europe.
So what does
that
mean for
oceania?
Threats to Reef
Destructive
fishing practices, unsustainable tourism, pollution and climate change
.
A
study presented
by
the
Coral Center
revealed that
93% of Reef
has been affected by coral bleaching

The
IPCC said
in 2007 that sea levels would rise between 7 and 23 inches by 2100Among those most threatened are the Marshall Islands
. The highest point on the 29 atolls and five islands is 33 ft.
above sea
level, which is alarming when most people live on coasts
