A recent study looking into regional tropical cyclone formation conditions in the east and central Pacific has projected that 2 to 3 times more tropical cyclones (Hurricanes) are likely to hit Hawaii in the later part of this century.

Pacific Warriors Day of Action against Climate change March 2, 2013Malo ni! My name is Mikaele Maiava. I'm writing from the Pacific Island archipelago of Tokelau to ask you to join with us in action as we take on the fossil fuel industry.

Last October, Tokelau turned off the last of its diesel generators. In their place, we switched on our solar plants, making Tokelau the first country in the world to become 100% renewably-powered. (See Tokelau installs 100 percent solar and ditches diesel power to combat climate change)

The tiny self governing territory of Tokelau in the South Pacific has become entirely solar-powered, with the third and final photovoltaic solar farm being turned on at the end of October 2012.

Tokelau consists of 3 small atolls with a population of about 1500 people 450km north from Samoa, and a dependent territory of New Zealand. The atolls are low lying with perhaps the highest points just 2 metres above sea level. Rising seas this century threaten the future of these islands with 1 metre rise in global sea level due to climate change conservatively predicted by the end of the century.

Increasing sea surface temperatures are imperilling coral reef ecosystems say Australian marine and climate scientists. A new scientific paper reveals that atmospheric warming of 2 degrees celsius is too much for nearly all the world's coral reef ecosystems, including the Great Barrier Reef. The scientists argue that to preserve greater than 10 per cent of coral reefs worldwide would require limiting global warming to below 1.5 °C. This equates to the goal of reducing carbon in the atmosphere to 350ppm, rather than a 2 degree rise or 450ppm that the UN Framwework Convention on Climate Change has adopted as the safe limit at several meetings.

Atmospheric concentration of CO2 currently stands at 392.41ppm. With current pledged reduction in emissions we are heading for 4.4 °C of warming by the end of the century according to the Climate Scoreboard.

An international study led by CSIRO oceanographer Dr Wenju Cai has identified that global warming is causing shifts in the rain band of the South Pacific Convergence Zone causing an increase in extreme weather across the island nation states of the South Pacific. The result of the movement causes drought and higher prevalence of forest fire in some areas while other islands experience extreme floods and increased frequency of tropical cyclones.

"Due to its strong rainfall gradient, a small displacement in the [South Pacific Convergence Zone] SPCZ's position causes drastic changes to hydroclimatic conditions and the frequency of extreme weather events such as droughts, floods and tropical cyclones experienced by vulnerable island countries in the region." says the paper.

A major new report on climate change in the Pacific Ocean region reports that the region is getter hotter, sea levels are rising, rainfall is changing and equatorial winds have weakened. While cyclone may tend to decrease slightly in the future, cyclone intensity is likely to be greater.

The report launched today - Climate change in the Pacific, scientific assessment and new research - contains 530 pages in 2 volumes with over 100 authors. The research was led by the Australian Bureau of Meteorology (BOM) and Commonwealth Scientific Industrial Research Organisation (CSIRO) with strong input from 15 National Meteorological Services, Geoscience Australia, and from universities in the region. The report includes observations and climate projections for 15 partner countries involved : Cook Islands, East Timor, Federated States of Micronesia, Fiji, Kiribati, Marshall Islands, Nauru, Niue, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu, and Vanuatu.

And in the green corner, Greenpeace an international kickass environment group ready for all comers. In the blue corner Fonterra an international (New Zealand-based) kickass dairy company, and they are in the ring over climate change.

We are calling for an international week of actions against Fonterra and the international dairy industry from November 8th to November 14th.

New Zealand Greenpeace activists "block(ed) coal being supplied to the boilers of Fonterra's Clandeboye factory, in Canterbury, with three tonnes of wood pellets and by locking themselves to equipment May 18".  Apparently our friends at NZ GP haven't done their homework regarding biomass wood pellets.
