Arctic ice cap melting 30 years ahead of forecast QUOTE
WASHINGTON (Reuters) - The Arctic ice cap is melting much faster than expected and is now about 30 years ahead of predictions made by the Intergovernmental Panel on Climate Change, a U.S. ice expert said on Tuesday.
This means the ocean at the top of the world could be free or nearly free of summer ice by 2020, three decades sooner than the global panel's gloomiest forecast of 2050.
"Right now ... the Arctic helps keep the Earth cool," Scambos said in a telephone interview. "Without that Arctic ice, or with much less of it, the Earth will warm much faster."
He discounted the notion that the sharp warming trend in the Arctic might be due to natural climate cycles. "There aren't many periods in history that are this dramatic in terms of natural variability," Scambos said.
He said he had no doubt that this was caused in large part by greenhouse gases in the atmosphere, which he said was the only thing capable of changing Earth on such a large scale over so many latitudes.
"We just barely now, I think, have enough time and enough collective will to be able to get through this century in good shape, but it means we have to start acting now and in a big way."
Even the gloomiest predictions are underestimates.
S.C. seeks public input on ocean energyQUOTE
The idea is to harvest energy from wind and water turbines and send the power back to shore through cables.
The greatest potential for wind energy is beyond three miles off the coast, outside state territorial waters, said John Clark, a spokesman for the state Energy Office.
While some people may not like to see a field of spinning wind turbines offshore, in Europe, such turbines are tourist attractions, Clark said.
Wave energy converters generate power by capturing the constant up-and-down motion of waves. Moored to the sea floor, the converters bob at the surface, resembling a small fleet of fishing boats.
Another way to generate power is with other turbines located beneath the surface, where steady currents spin propellers.
While the energy is free, getting it to customers is the challenge.
"It's very expensive," said Laura Varn, a spokeswoman for Santee Cooper.
EU reiterates commitment to tackle global warmingQUOTE
BANGKOK (AFP) - The European Union on Tuesday reiterated its commitment to cut greenhouse gas emissions despite the lack of an agreement between the United States and the region over ways to tackle global warming.
The United States is responsible for 25 percent of the world's greenhouse gases, with only some states like California taking initiatives to reduce pollution.
Coral Reef Devastation Linked to Global WarmingQUOTE
Coral disease outbreaks have struck the healthiest sections of Australia’s Great Barrier Reef, and a new study has conclusively linked disease severity to ocean temperature and climate change for the first time.
“With this study, speculation about the impacts of global warming on the spread of infectious disease among susceptible marine species has been brought to an end,” said Don Rice, director of the National Science Foundation’s Chemical Oceanography Program, which helped fund the research.
