2,000-year-old ice core uncover the climate change

Researchers studying polar ice samples from Antarctica claimed was on the verge of outlining 2,000 year climate record will be instructions on how global warming is affecting the future of mankind.

An international team of venturing into Aurora Sunken in Antarctica within the framework of a five-week project began last December, to drill the ice sample is needed to bridge the gap in knowledge about the changes in ambient temperature of 20 the last century.

Using the latest technology to uncover the secrets of the past, scientists hope to get information in order to improve climate models and senses a normal frequency and pattern are seen now in extreme events such as droughts, cyclones and floods.

"Papers that will be generated from this project can inform and improve the climate models of human knowledge for the sake of promoting the human about what influenced climate in the past," said Nick Gales, chief scientist of the Australian Antarctic Division in Tasmania.

"It will greatly assist our ability to projecting climate change," he told Reuters on Thursday. The main ice core taken at length 303 meters scientists that will provide annual climate record for the last 2,000 years.

Two smaller nuclei, each of length 116 meters and 103 meters, covers last 800 to 1,000 years, will provide additional ice for chemical analysis in a broad volume. "Just to go there and drill a few hundred meters down the Antarctic ice cores in one season and then restore everything, then it's really great search," said Gales.

Two tons of ice are now core parts sent to laboratories around the world ice cores for analysis. "This is a great science," said Gales.

"It took a great collaboration to attract a lot of people and a lot of devices up to hundreds of kilometers into the interior of the Antarctic continent."

The scientists will take measurements and begin to publish next year the results in 28 to 24 months, said Gales."They will continue until a few more years and then each paper will provide another key part of the small pieces of a big puzzle," he said.

Series of long-term data from ice cores, along with other information, will advance the understanding of extreme events, said Gales, by revealing how your humans affect climate change through the burning of fossil fuels.

Concave the Aurora project involves 15 partner organizations from six countries, namely Australia, China, Denmark, France, Germany and the United States. Efforts paved the way for more ambitious drilling expedition in collecting ice cores one million years old in the future, said Mark Curran, the scientist chief told Reuters. *** [EKA | FROM VARIOUS SOURCES | REUTERS]
