What might have happened back in the Pliocene, say Fedorov and his colleagues, is that an initial bout of global warming led to severer hurricanes - a distinct possibility supported by recent research published in Science and Nature Geoscience - and severer hurricanes led to more warming. Although most of us think about hurricanes in terms of their impact on the land, they also wreak havoc on the sea, churning the water like giant mixers and forcing warm surface waters deeper. When that occurs in the central Pacific, "the ocean responds by sending that water to the East," where it rises again...
...long suspected that global warming could make hurricanes more intense somehow, but the new study suggests the effect works both ways: tropical cyclones could help drive up temperatures in response. "We're suggesting that hurricanes could have created a permanent El Niño condition," says Yale's Alexey Fedorov, lead author of the study. (See pictures of the effects of climate change...
...really just a rearrangement of the ocean's heat, not an overall increase - it could trigger an environmental feedback cycle that could. When you make the tropics warmer, "you also get more evaporation, so there's more water vapor in the atmosphere, which is a strong greenhouse gas," says Fedorov. So intense hurricanes can create conditions that warm the planet overall, leading to even more intense hurricanes, leading to more water vapor, and so on - a loop that could plausibly help explain the Pliocene's puzzling temperatures...
...Fedorov agrees that the new paper doesn't solve the puzzle of a warmer Pliocene by itself. "This is just part of the story," he says. "It's still the subject of intense research. We describe one piece of the puzzle, but there are many more pieces...
...Ibragimov is sponsored by a local oil company, Nafta Moscow. It is just this sort of arrangement that Fedorov believes will perpetuate the current trend of Slavic champions. "We have a lot of rich companies that can have one boxer, or a team of boxers," says the promoter. "We have asked the government for more recommendations. They need only to tell these companies that this is the thing they need to do. To many companies, government opinion is very important." This new economic model, says Kathy Duva, CEO of Main Events, Holyfield's promoter, is "why we all need...
