[作者：Melillo, JM; Reilly, JM; Kicklighter, DW; Gurgel, AC; Cronin, TW; Paltsev, S; Felzer, BS; Wang, XD; Sokolov, AP; Schlosser, CA,期刊：Science, 页码：1397-1399 , 文章类型： Article，,卷期：2009年326-5958] A global biofuels program will lead to intense pressures on land supply and can increase greenhouse gas emissions from land-use changes. Using linked economic and terrestrial biogeochemistry models, we examined direct an... Coupling of CO2 and Ice Sheet Stability Over Major Climate Transitions of the Last 20 Million Years [作者：Tripati, AK; Roberts, CD; Eagle, RA,期刊：Science, 页码：1394-1397 , 文章类型： Article，,卷期：2009年326-5958] The carbon dioxide (CO2) content of the atmosphere has varied cyclically between similar to 180 and similar to 280 parts per million by volume over the past 800,000 years, closely coupled with temperature and sea level. ... Tracking the Variable North Atlantic Sink for Atmospheric CO2 [作者：Watson, AJ; Schuster, U; Bakker, DCE; Bates, NR; Corbiere, A; Gonzalez-Davila, M; Friedrich, T; Hauck, J; Heinze, C; Johannessen, T; Kortzinger, A; Metzl, N; Olafsson, J; Olsen, A; Oschlies, A; Padin, XA; Pfeil, B; Santana-Casiano, JM; Steinhoff, T; Telsz,期刊：Science, 页码：1391-1393 , 文章类型： Article，,卷期：2009年326-5958] The oceans are a major sink for atmospheric carbon dioxide (CO2). Historically, observations have been too sparse to allow accurate tracking of changes in rates of CO2 uptake over ocean basins, so little is known about h...
