Apparently, the earth's oceans have a large effect on global temperature.

Ocean currents to blame for warming: expert
THE United States' leading hurricane forecaster says global ocean currents, not human-produced carbon dioxide, are responsible for global warming.
William Gray, a Colorado State University researcher, also said the Earth may begin to cool on its own in five to 10 years.
Speaking to a group of Republican MPs, Dr Gray had harsh words for researchers and politicians who said man-made greenhouse gases were responsible for global warming.
"They are blaming it all on humans, which is crazy," he said.
"We're not the cause of it."
[...]Yesterday, Dr Gray said that politics and research into global warming had created "almost an industry" that had frightened the public and overwhelmed dissenting voices.
He said research arguing that humans were causing global warming was "mush" based on unreliable computer models that could not possibly take into account the hundreds of factors that influenced the weather.
Earth's Climate Is Seesawing, According To Climate Researchers
Science Daily — During the last 10,000 years climate has been seesawing between the North and South Atlantic Oceans. As revealed by findings presented by Quaternary scientists at Lund University, Sweden, cold periods in the north have corresponded to warmth in the south and vice verse. These results imply that Europe may face a slightly cooler future than predicted by IPCC, the Intergovernmental Panel on Climate Change.
[...]
We don’t know with certainty what will happen. Some attempts at measuring ocean currents suggest a recent weakening of the Gulf Stream, and the transport of heat to the North Atlantic region may well decrease in the future as a result of increased precipitation. Such a scenario might lead to less warming in Europe than predicted by the IPCC, but we will probably not face an arctic climate, summarizes Svante Björck.
