Argentine glacier advances despite global warming By JEANNETTE NEUMANN, Associated Press Writer BUENOS AIRES, Argentina – Argentina's Perito Moreno glacier is one of only a few ice fields worldwide that have withstood rising global temperatures. Nourished by Andean snowmelt, the glacier constantly grows even as it spawns icebergs the size of apartment buildings into a frigid lake, maintaining a nearly perfect equilibrium since measurements began more than a century ago. "We're not sure why this happens," said Andres Rivera, a glacialist with the Center for Scientific Studies in Valdivia, Chile. "But not all glaciers respond equally to climate change." Viewed at a safe distance on cruise boats or the wooden observation deck just beyond the glacier's leading edge, Perito Moreno's jagged surface radiates a brilliant white in the strong Patagonian sun. Submerged sections glow deep blue. And when the wind blows in a cloud cover, the 3-mile-wide (5 kilometer) glacier seems to glow from within as the surrounding mountains and water turn a meditative gray. Every few years, Perito Moreno expands enough to touch a point of land across Lake Argentina, cutting the nation's largest freshwater lake in half and forming an ice dam as it presses against the shore. The water on one side of the dam surges against the glacier, up to 200 feet (60 meters) above lake level, until it breaks the ice wall with a thunderous crash, drowning the applause of hundreds of tourists. "It's like a massive building falling all of the sudden," said park ranger Javier D'Angelo, who experienced the rupture in 2008 and 1998. The rupture is a reminder that while Perito Moreno appears to be a vast, 19-mile-long (30 kilometer) frozen river, it's a dynamic icescape that moves and cracks unexpectedly. "The glacier has a lot of life," said Luli Gavina, who leads mini-treks across the glacier's snow fields. Argentine glacier advances despite global warming - Yahoo! News look despite "global warming", not every iceberg is shrinking....why didnt al gore "research this" with his movie about all the research he didnt do
i have...its just kinda seems like global warming is more of a naturally reoccurring trend if some glaciers melt while others grow. i guess i just had to bash al gore cuz i hate him so much...we have not lived on earth long enough to know if global warming actually happens over and over....its like we are at the end of an ice age and another one is coiming in the future..the ice melts but then there is a big freeze
..thats an iceburg...thats how most of them look...most of the iceburg is underwater...thats what sank the titanic, you cant tell how big one is just by the tip that sticks out of the water
He brought it to the fore front, which is good. The temperatures ARE rising, whether you think its due to human involvement or not....Point is we should cut back, because even if we aren't changing the earth's natural cycles we are polluting and causing harm.
I find it ridiculous that people analyze icebergs and start freaking the fuck out when one starts to fall apart. These things aren't made to last forever; they're supposed to break. Global warming is a real thing, but humans are not solely responsible. The earth has a cycle that it likes to run through.
