Abrupt climate change：Debate or action

Global abrupt climate changes have been documented by various climate records, including ice cores, ocean sediment cores, lake sediment cores, cave deposits, loess deposits and pollen records. The climate system prefers to be in one of two stable states, i.e. interstadial or stadial conditions, but not in between. The transition between two states has an abrupt character. Abrupt climate changes are, in general, synchronous in the northern hemisphere and tropical regions. The timescale for abrupt climate changes can be as short as a decade. As the impacts may be potentially serious, we need to take actions such as reducing CO2 emissions to the atmosphere.     

用带时序子模块的系统动力学模型预测Brent原油价格

提出在系统动力学模型中加入时序自回归AR(p)子模块，并且自动确定每个AR(p)子模块的阶数p。带时序子模块的系统动力学模型既体现了因素问的横向因果关系，又体现了每个因素的纵向关系。建立欧佩克(OPEC)石油产量、世界GDP、煤炭产量与价格、天然气、需求量、供求差额、消费系数、非欧佩克石油产量、非欧佩克供求差额，石油库存和OPEC组织的期望油价共十一个因素影响下的Brent原油价格预测模型，模型的预测结果表明：在系统动力学模型中加入时序自回归AR(p)子模块的方法是可行的、有效的，并且能提高模型的预测精度。
