But this is a very familiar story to us. With thinner sea ice arriving later and leaving earlier in the year, coastal communities are experiencing more intensified storms with larger waves than they have ever experienced. This threat is being compounded by the loss of permafrost which has kept river banks from eroding too quickly.
Ancient global warming was jarring, not subtle, study finds By Robert Lee Hotz, Times Staff Writer January 5, 2007 Foreshadowing potential climate chaos to come, early global warming caused unexpectedly severe and erratic temperature swings as rising levels of greenhouse gases helped transform Earth, a team led by researchers at UC Davis said Thursday. The global transition from ice age to greenhouse 300 million years ago was marked by repeated dips and rises in the amount of carbon dioxide in the atmosphere and wild swings in temperature, with drastic effects on forests and vegetation, the researchers reported in the journal Science. "It was a real yo-yo," said UC Davis geochemist Isabel Montanez, who led researchers from five universities and the Smithsonian Museum of Natural History in a project funded by the National Science Foundation. "Should we expect similar but faster climate behavior in the future? One has to question whether that is where we are headed." The provocative insight into planetary climate change counters the traditional view that global warming could be gradual and its regional effects easily anticipated.
