Carbon dioxide accumulation in the atmosphere reached a record high last year and grew at the fastest rate in 30 years, the United Nations' climate agency reported Tuesday. Wendy Watson-Wanker, executive secretary of UNESCO's Intergovernmental Oceanographic Commission, warned that time is running out in the mission to prevent devastating climate change. "It is high time the ocean, as the primary driver of the planet’s climate and attenuator of climate change, becomes a central part of climate change discussions,” said Watson-Wanker.
