Consequences of Global Climate change on:

Agriculture

Biomes and animals

Extreme Weather events

Carbon Stores

Oceans

Biosphere

Water and rising sea levels

1 degree Celsius Increase

2 degree Celsius increase

4 degree Celsius increase

Ice

Heatwaves and forest fires increase in regions like the Mediterranean, and South Africa

Coastal erosion

Flooding

Waves + Tsunami

Heatwaves which killed tens of thousands of people in Europe in 2003 will come back every year

In low-lying areas e.g. Netherlands, Egypt

Less ice = greater potential of wave formation

Due to sea ice melting (Glaciers)

Average rise of about 23cm since 1880 around the world

February 2016, lowest quantity of Arctic sea ice ever recorded

Length of melting season increased by three weeks since 1980

E.g. Himalayan glaciers melting, Greenland

In 2003, less than 1/12 of sea ice is 4 or more years old

potential displacement of up to 200 million people

Especially in Greenland and Antarctica

4 million km^2 of land lost

home to 5% of worlds population

E.g. Maldives will cease to exist, 400 000 islanders will have to migrate

Creates a positive feedback loop, as the larger waves would destroy more sea ice

Increase in wave formation (5 meters long in Beaufort Sea)

impact on the water supply of ca. 1,5 billion people

Amazonian Rainforest will turn to desert and grassland.

The oceans consist of about 38 petagrams of carbon(38 billion kilograms)

Increasing plant activity causing increasing carbon in the oceans

South England summer temperatures will be 40 degree Celsius

Organic matter is stuck under the ice, resulting from frozen soil.

Make oceans more acidic, makes the coral die

Arctic Sea will disappear for good in the summer

Agriculture will drop, making half of a billion more people at risk of starvation.

most of the Earth's carbon is stored in rocks

Most of world's corals will die, e.g. Great Barrier Reef

West Antarctic ice sheets will collapse, Greenland ice sheets will melt

85% of the carbon

A

1/3 of the world's species will become extinct, not enough time for adaptation to the new environment

Amazonian rainforest --> desert + grasslands

5% of the carbon

Deserts created e.g. Italy, Spain, Greece and Turkey (50 degree Celsius)

1/3 of world's species will become extinct

acidified water

Increase in growing season

2 degree Celsius increase

200 million people exposed to hunger

3 degree Celsius increase

550 million people exposed to hunger

35% drop in crop yields.

Across Africa and Middle East

With a 4 degree increase in temperature, the Arctic would completely diappear

Extinction of arctic wildlife e.g. Polar bears

Norther Countries (eg. Canada)

Location changes of crop growing areas
