sink</title></head><body>
<div>Excerpt from release: "The study focused on Earth's natural
carbon cycle responded during both periods of rapid, and less rapid,
warming that would normally be expected.<br>
<br>
"It revealed that the total amount of carbon taken up by land
ecosystems slowed during periods of rapid warming, and sped up during
periods of slower warming.<br>
<br>
"More significantly, the team demonstrated that while rates of
photosynthesis remained constant during the periods of slower warming,
the forests released less carbon back into the atmosphere - meaning
the Earth is storing much more carbon during these warming
hiatuses.<br>
</div>
<div>" 'The global carbon sink has been surprisingly strong
during the period from 1998 to 2012, and we now begin to understand
the causal mechanisms', says Ashley Ballantyne of University of
Montana, and lead author of the new research. "</div>

<div>Satellite and atmospheric observations show that the rate of net
biome productivity has accelerated over the warming 'hiatus' period
(1998-2012). This net gain results from reduced respiration, rather
than increased primary productivity.</div>
