Tiny islands with big climate change problems

Tiny island states that speck the vast swathe of the Pacific Ocean have a far greater importance in understanding global climate change than their tiny populations would suggest. This was the message given to delegates during a side event of the UN Framework Convention on Climate Change's 19th annual meeting in Warsaw today.


The delegates from Fiji and Samoa believe their nations do not get the support they need to conduct vital climate observations in the region.

"In terms of climate change, up to 90 per cent of heat is absorbed by oceans, so understanding how the oceans behave is critical to understanding how the atmosphere will change," says Neville Koop, a climatology advisor with the Samoan delegation.

Considering the huge marine areas that Pacific nations cover — Kiribati consists of 800 square kilometres of coral atolls spread over an area half the size of Europe — the poor observational capacity of island states creates a large gap in the global climate data set, he says.

Better oceanic and high altitude measurements, as well as more rudimentary metrics such as rainfall and atmospheric pressure are vital for producing more accurate climate models, Koop adds.

Furthermore, as the birthplace of the El Niño Southern Oscillation weather system that periodically warms the waters of the Pacific Ocean, this patch of ocean influences climates across Asia, Africa and the Americas, and so accurate observations are necessary to predict future changes, he says.

But with populations often in the tens of thousands, these states' meteorological agencies can never hope to fulfill this vital task alone, Koop says.

Some governments, such as the United Kingdom's, are already working to increase the observational capacity in the Pacific, but a concerted international effort is needed to fully plug the data gaps, he says.
