Climate change is likely to have a massive impact on marine micro-organisms that produce half the planet’s oxygen, new research suggests. Analysis of 35,000 seawater samples from around the world suggests rising ocean temperatures are likely to have significant effects on plankton. The microscopic organisms are the bottom of the marine food chain. But they also remove as much carbon dioxide from the atmosphere as rainforests.
Scientists who mounted a four-year global expedition to study the “health” of the world’s oceans are due to reveal the first detailed overview of the global planktonic ecosystem. They warned that the United Nations climate change conference in November must react to their findings on global warming. Continue reading
