    Description: Zhao and Running (Reports, 20 August 2010, p. 940) reported a reduction in global terrestrial net primary production (NPP) from 2000 through 2009. We argue that the small trends, regional patterns, and interannual variations that they describe are artifacts of their NPP model. Satellite observations of vegetation activity show no statistically significant changes in more than 85% of the vegetated lands south of 70 degrees N during the same 2000 to 2009 period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Samanta, Arindam -- Costa, Marcos H -- Nunes, Edson L -- Vieira, Simone A -- Xu, Liang -- Myneni, Ranga B -- New York, N.Y. -- Science. 2011 Aug 26;333(6046):1093; author reply 1093. doi: 10.1126/science.1199048.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geography and Environment, Boston University, Boston, MA 02215, USA. arindam.sam@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21868655" target="_blank"〉PubMed〈/a〉

    Description: Identifying leads and lags between high- and low-latitude abrupt climate shifts is needed to understand where and how such events were triggered. Vascular plant biomarkers preserved in Cariaco basin sediments reveal rapid vegetation changes in northern South America during the last deglaciation, 15,000 to 10,000 years ago. Comparing the biomarker records to climate proxies from the same sediment core provides a precise measure of the relative timing of changes in different regions. Abrupt deglacial climate shifts in tropical and high-latitude North Atlantic regions were synchronous, whereas changes in tropical vegetation consistently lagged climate shifts by several decades.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hughen, Konrad A -- Eglinton, Timothy I -- Xu, Li -- Makou, Matthew -- New York, N.Y. -- Science. 2004 Jun 25;304(5679):1955-9.
