At the Pacific Islands Forum in Majuro (Marshall Islands), sixteen states renewed on Wednesday, September 4, their commitment to fight climate change, notably through marine protected areas.
Pacific islands are directly threatened by the rise in sea levels: some atolls stand just 2-3 meters above the surface. The Majuro Manifesto is a call for immediate action, and will be presented at the United Nations general assembly in New York.
Two new studies show that ocean acidification is negatively affecting species and ecosystems, albeit to varying degrees. Acidification may also amplify global warming, according to a third study.
The oceans absorb more than a quarter of anthropogenic carbon dioxide emitted to the atmosphere. They form a natural store without which the Earth would now be a good deal warmer. But their storage capacities are limited and the absorption of carbon dioxide results in their acidification.
Warming oceans are causing marine species to change breeding times and shift homes with expected substantial consequences for the broader marine landscape, according to a new global study.
The three-year research project has shown widespread systemic shifts in measures such as distribution of species and phenology -- the timing of nature's calendar - on a scale comparable to or greater than those observed on land.
For scientists studying summer sea ice in the Arctic, it’s not a question of “if” there will be nearly ice-free summers, but “when.” And two scientists say that “when” is sooner than many thought — before 2050 and possibly within the next decade or two.
