Climate change: Social determinants of global warming over the 21st century

 
In this recent modeling study, how climate change awareness, the cost and effectiveness of climate change mitigation strategies, and political responses all interact to determine the path of global warming in the 21st century. Became clear.The paper reporting this finding isNature Will be published in.In this study, we analyzed 10 possible future policies and the trajectory of greenhouse gas emissions, and based on the findings obtained, we found that climate and our society are related to climate change modeling. The importance of considering basic interactions was clearly demonstrated.

There are complex interactions between climate and our society, and interactions between social, political, economic and technological systems can affect the trajectory of greenhouse gas emissions. ..However, the combined impact of social, political, economic and technological systems on future greenhouse gas emissions and temperature scenarios has created a situation in which policies may be formulated. Nevertheless, research has not yet progressed sufficiently.

Now, Frances Moore and colleagues use an integrated multidisciplinary model that combines data from a wide range of social, political and technological disciplines to simulate possible future emissions and policy trajectories of 10.These trajectories can be divided into five groups, with global warming in 5 fluctuating within 2100-1880 ° C above the average temperature during the period 1910-1.8. Moore et al. Revealed several important factors that could influence emissions and policy trajectory fluctuations during the 3.6st century and subsequent warming.These factors include how the general public perceives climate change, the cost and effectiveness of climate change mitigation technologies, and the responsiveness of political systems.

Moore et al. Found that the complex link between different social, political and technological factors influences the development and future direction of climate change policies and the outcome of greenhouse gas emissions. We conclude that it can do.Determining the extent of this impact requires a unique approach that treats these emissions and policy trajectories as a result of this model, rather than as input to the integrated climate-social model.
