Rise of 6.4 degrees - Most of life on the planet is exterminated
The
oceans lose their oxygen and turn stagnent, and releaseing hydrogen
sulphide gas, which can destroy the ozone layer. Humanity reduced
to a few survivors eking out an existence near the poles.
Rise
of 5.4 degrees - Sea levels rise by 15-20 feet
The West Antarctic ice
sheet breaks up, eventually adding 15-20 feet to global sea levels.
Glaciers drying up around the world will threaten millions of lives
in India and Bangladesh. World food supplies run out.
Rise of
4.4 degrees - Spread of dessert and collapse of agriculture.
Permafrost
in the Arctic and Siberia melts and vast quantities of CO2 is released
into the atmosphere. Growth of deserts in Spain, Greece and Italy.
More than 50% of wild species are wiped out. Agriculture is no longer
possible in Australia.
Rise of 3.4 degrees - Rainforest turns
to dust
The Amazonian rainforest burns in a firestorm covering South
America with ash and smoke. The entire Arctic ice-cap disappears
in the summer months, leaving the North Pole ice-free for the first
time in 3 mill. years.
Rise of 2.4 degrees - Coral reefs almost
extinct
Sand dunes appear across 5 states from Texas in the south to
Montana in the north, which wipes out agriculture and cattle farms
in these states.
The Great Barrier Reef is wiped, and about 1/3
of all species on the planet face extinction. Low-lying nations are
lost due to rising sea levels.
