Changes to the climate have had major impacts on the oceans and the biological systems that live there. A new study sheds more light on how fast these systems respond to changes. What the authors found is that short-term climate changes can require 1,000 years for recovery. This means the current harm caused to the deep oceans by the changing climate will last for many centuries to come.
The new study, published in the Proceedings Of The National Academy Of Sciences by Dr Sarah Moffitt and her colleagues is novel for a number of reasons. The researchers took core samples from ocean floor regions off the coast of California. The location was chosen in part because of the exceptional synchrony between sediment archives from offshore California and ice core records from the Greenland Ice sheet.
