Earth system modelling and analysis

在国家科学研究委员会发现基金的支持下进行的研究分为两个主题：主题1：我们将通过纳入湿地甲烷产生的影响，对永久冻土和高纬度碳循环反馈对未来气候变化的影响进行定量评估。我们还将研究湿地甲烷排放在解释末次冰期古气候冰芯记录中观测到的大气甲烷浓度变化中的潜在作用。主题2：我们将全面了解北大西洋经向翻转对全球变暖的响应，这是世界各地使用的许多地球系统模型所预测的。我们将进一步探讨未来格陵兰冰盖融化对这种反应的潜在影响。

Research conducted with support from this NSERC Discovery Grant falls under two themes:Theme 1: We will develop a quantitative assessment of the magnitude of the permafrost and high latitude carbon cycle feedbacks on future climate change by incorporating the effects of wetland methane production. We will also examine the role of wetland methane emissions in potentially explaining the variations in atmospheric methane concentrations observed in paleoclimate ice core records from the last glacial cycleTheme 2: We will develop a comprehensive understanding of the response of the North Atlantic Meridional Overturning to global warming as projected by numerous Earth System Models in use around the world. We will further explore the potential effect that future melting of the Greenland Ice Sheet will have on this response.
