Who controls the numbers? Small Island Survival, 350ppm & 1.5°C 2

What difference can a degree or two make? Well the answer, as I’m sure that you will know is a lot. The image below taken from the IPCC’s fourth assessment report (AR4) gives a simple (although now out of date) picture of what a degree means.

The impacts and extent of climate change is subtle and effects unevenly distributed, a degree for one country such as the UK or the US may not be an existential crisis but for people living in small island developing states (SIDS) is certainly is. These states, drawn from all oceans and regions of the world: Africa, Caribbean, Indian Ocean, Mediterranean, Pacific and South China Sea make up 5% of the world’s population and a great proportion of the worlds cultural diversity. It’s no secret that these states are the most vulnerable to climate change but for these countries the numbers that are negotiated literally in no uncertain terms mean the life of death of their homeland, and their culture. At Copenhagen some of the most moving and courageous speeches were made by these states and I would urge you to take a look at the following two speeches by Tuvalu and The Maldives who have fought the corner for the Alliance of Small Island States (AOSIS) for a long time.

Visualising the gap between political and scientific reality.

Keep an eye on the Climate Scoreboard during the next two weeks… Note the dark blue curve in the graphic, this is the probability distribution, it shows the full range of temperature rise the current national emissions proposals would likely give rise to. Currently it’s 2-6 degrees with 3.8 degrees is the most likely outcome (according to their analysis, climate sensitivity etc.).

With my risk managers hat on, it’s hard not to notice that we could go way above 3.8 degrees… it looks like there’s a 5-10% of going over 5 degrees… the sting’s in the tail as they say!
