Really? So is it or isn't it?

1. The impact of global warming on the vast Southern Ocean around Antarctica is starting to pose a threat to ocean currents that distribute heat around the world, Australian scientists say, citing new deep-water data.
Australian scientists warned last month that waters surrounding Antarctica were also becoming more acidic as they absorbed more carbon dioxide produced by nations burning fossil fuels.
Acidification of the ocean is affecting the ability of plankton — microscopic marine plants, animals and bacteria — to absorb carbon dioxide, reducing the ocean's ability to sink greenhouse gases to the bottom of the sea.
2. Melting ice may slow global warming
Scientists discover that minerals found in collapsing ice sheets could feed plankton and cut C02 emissions.
Professor Rob Raiswell, a geologist at the University of Leeds, says that as the sheets break off the ice covering the continent, floating icebergs are produced that gouge minerals from the bedrock as they make their way to the sea. Raiswell believes that the accumulated frozen mud could breathe life into the icy waters around Antarctica, triggering a large, natural removal of carbon dioxide from the atmosphere.

Environmental science (Art?), you got to love it!
