It is about what is hapening to life, in this small island, in the middle of the Pacific Ocean.
It has to do with ourselves in our daily lives ! we must act urgently !

The World Oceans is what keeps OUR PLANET ALIVE !!

Strong images, great photography and a seriuos situation that has to do with our Oceans, Ourselves and Actions to be Taken to diminish the impact urgently ! Think about it because it has to do with the future of your family and children, and Life itself !!

They need donations for the project ! Please, visit the website and watch the film.

Dry lands getting drier, wet getting wetter: Earth's water cycle intensifying with atmospheric warming

ScienceDaily (May 21, 2012) — A clear change in salinity has been detected in the world's oceans, signalling shifts and an acceleration in the global rainfall and evaporation cycle.

n a paper just published in the journal Science, Australian scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Lawrence Livermore National Laboratory, California, reported changing patterns of salinity in the global ocean during the past 50 years, marking a clear fingerprint of climate change.
Lead author, Dr Paul Durack, said that by looking at observed ocean salinity changes and the relationship between salinity, rainfall and evaporation in climate models, they determined the water cycle has strengthened by four per cent from 1950-2000. This is twice the response projected by current generation global climate models

Potential instability in West Antarctic Ice Sheet from newly discovered basin size of New Jersey

Potential instability in West Antarctic Ice Sheet from newly discovered basin size of New Jersey

ScienceDaily (May 10, 2012) — Using ice-penetrating radar instruments flown on aircraft, a team of scientists from the U.S. and U.K. have uncovered a previously unknown sub-glacial basin nearly the size of New Jersey beneath the West Antarctic Ice Sheet (WAIS) near the Weddell Sea. The location, shape and texture of the mile-deep basin suggest that this region of the ice sheet is at a greater risk of collapse than previously thought.

Pacific islands on equator may become refuge for corals in a warming climate due to changes in ocean currents

Pacific islands on equator may become refuge for corals in a warming climate due to changes in ocean currents

The Future: Global climate models predict a sea surface temperature rise of nearly 3 degrees C (5.4 degrees F) by the end of the century. According to Karnauskas’s and Cohen’s fine-scale model, equatorial trade winds will weaken, causing a weakening of the surface current. In turn, the frictional drag on the EUC will lessen, and the EUC will strengthen, carrying more cool, nutrient-enriched water to the surface around the Gilbert Islands. The result will be enhanced productivity close to the islands, and slower warming during the coming century than neighboring islands not in the EUC’s path. The slower warming may allow corals to adapt and survive, making the Gilberts a refuge for coral reef ecosystems. (Credit: Illustration by Amy Caracappa_Qubeck, Woods Hole Oceanographic Institution
ScienceDaily (Apr. 29, 2012) — Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish.
