Effects of climate change- discuss today

• Heat New records, more heat waves
• More frequent and severe cyclones, storms, floods
• Great Barrier Reef devastation
• Sea-level rise in our area, distant future

Sea-level rise
The surface mass balance becomes negative at a
global average warming in excess of 1.9C to
4.6C. If a negative surface mass balance were
sustained for millennia, that would lead to
virtually complete elimination of the Greenland
ice sheet and a resulting contribution to sea
level rise of about 7 m. IPCC Fourth
Assessment Report, 2007

If you dont take your car to work for one day
its a drop in the bucket. But if 400,000 people
leave their car at home for one day a week,
thats huge.You as a (statistically)
insignificant person are part of a much bigger
movement.David SuzukiInternationally renowned
environmentalist and scientist
