摘要
以IPCC为主流的观点认为,由于人类活动产生的以CO2为代表的温室气体导致了全球气温升高。但国际学术界对IPCC的理论和数据一直存在诸多质疑。本研究综述了当前对IPCC主流观点的主要质疑,希望可以辩证地看待气候变化,谨慎考虑CO2在气候变化中的作用,从而对将来气候变化做出更加全面的评估,采取更正确的应对政策。
IPCC claimed that ＂most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations＂.The international scientific society has questioned the so-call ＂anthropogenic warming＂ from experimental data to theoretical models.The study review the main concerns on the anthropogenic warming,and provide a second opinion for the climate changes debate.We need to be more cautious on the role of CO2 in climate changes,and made a more comprehensive assessment on climate changes,and more correct policies on it.
