Why so much controversy?

Ramsdorf (2007) The rate of sea-level rise is roughly proportional to the magnitude of warming above the temperatures of the pre–Industrial Age. So IPPC estimates are too conservative!

Holgate et al. (2007) There is no such relationship but the IPPC estimates are too conservative! The observations are underestimated.

AOSIS PositionAOSIS Position

Stabilise CO2 at 350 ppmGlobal average surface temperature

increase should be limited to well below 1.5º C above pre-industrial levels

Global greenhouse gas emissions must peak by 2015.

Global CO2 reductions of greater than 85% are required by 2050.

Is that acheivable?

The Benefits of Green PowerThe Benefits of Green Power

Shifting the world onto a low-carbon path could eventually benefit the economy by $2.5 trillion a year. (Stern, 2006)

Unabated climate change could cost the world at least 5% of GDP each year; if more dramatic predictions come to pass, the cost could be more than 20% of GDP.

By 2050, markets for low-carbon technologies could be worth at least $500bn.

Take home messages!Take home messages!

1. Climate change is a reality and happening2. Action needs to be taken now to reduce vulnerability

and avoid long-term costs associated with climate change impacts.

3. Early planning and proactive approaches are needed.

4. Further knowledge development and applied research is critical to build capacity for adaptation and resilience building

5. Climate change has important links to the economy, noting especially the effects of the recent food and energy crisis, as well as the impact of recent extreme events on coastal infrastructure and tourism.
