Climate science chief sees ‘huge gaps’ in research

Dawn via AP (Paksitan): From the methane-laden tundra of the far north to the depths of the oceans, world governments need to spend more on cutting-edge research to “get a handle” on how much and how quickly the world will warm in decades to come, says the head of the UN climate science network.

“There are huge gaps in the effort as far as scientific research is concerned,” Rajendra Pachauri told The Associated Press, pointing to concerns that the Arctic’s thawing permafrost is releasing powerful global warming gases, and the oceans might eventually turn from absorbing carbon dioxide to spewing it into the atmosphere.

...Describing areas where more intense research is needed, Pachauri spoke of the uncertain state of the Arctic tundra. Last year, he asked his scientific network to focus on possible “abrupt, irreversible climate change” from thawing permafrost, tundra soil frozen year-round, covering almost one-fifth of Earth’s land surface and running up to 600 meters (2,000 feet) deep.

…“It’s basically the fact that people have not carried out enough measurement so that we can get a handle on how this is going to change in the future, what sort of increase of temperature will occur with the melting of the permafrost,” Pachauri said.

Similarly, he said, “the oceans require a lot more concentrated attention.” Researchers are growing deeply worried about the growing acidification of the oceans, from their absorption of excess atmospheric carbon dioxide. More acidic waters make it more difficult for coral, oysters and other undersea life to produce their calcium carbonate shells, threatening to blow holes in the oceanic food chain….
