World's largest iceberg headed for collision reveals 37-million-year-old secret

India Today  

All eyes are on the world's largest iceberg that is drifting towards a collision with an island after breaking away from Antarctica. While climate change is indeed influencing the frequency and size of these icebergs, recent research suggests that the relationship between climate change and extreme calving events is more complex than initially thought. CLIMATE CHANGE AND CALVING EVENTS Climate change is warming the air and ocean around Antarctica, leading to faster and more frequent calving of icebergs. However, studies have found that extreme calving events, which produce massive icebergs, do not appear to be directly linked to climate change. By studying ancient debris found near South Orkney, scientists have discovered evidence of icebergs dating back 37 million years, suggesting that Antarctica may have had an ice cap even during warmer periods.

World's biggest iceberg is just under one trillion tonnes, study shows

Daily Mail  

New satellite measurements reveal the true scale of the world's largest iceberg. According to the British Antarctic Survey, which visited A23a last week, the iceberg is travelling north at a rate of about 30 miles per day. The European Space Agency's CryoSat satellite has found that one part of the iceberg's base in particular stuck out a lot deeper, making …

Even frozen Antarctica is being walloped by climate extremes, scientists find

Associated Press  

Even in Antarctica — one of the most remote and desolate places on Earth — scientists say they are finding shattered temperature records and an increase in the size and number of wacky weather events. The continent “is not a static giant frozen in time,” they said, but instead feels climate change’s wrath and extremes “sporadically and unpredictably.” Anna Hogg, …
