New analysis of strontium isotopes reveals how the carbon cycle responds to changing climate
New analysis of strontium isotopes reveals how the global carbon cycle responds to changing climate.

A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry reflecting changing climate conditions over the past 35 million years.
Science, provide new insights into the inner workings of the global carbon cycle and the processes by which carbon is removed from the environment through the deposition of carbonates.
"Strontium is very similar to calcium, so it gets incorporated into the calcium carbonate shells of marine organisms," said lead author Adina Paytan of the University of California, Santa Cruz.
