Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Ageing Society in Developed Countries Challenges Carbon Mitigation
发达国家 老龄化社会 碳减排
2023/4/18
Populations in developed countries are ageing. However, the impact of senior citizens' consumption on global carbon mitigation is poorly understood. Here we find that senior citizens have played a lea...
Atlases are collections of illustrated data, often maps, which give an overview - as well as some details - of one or several topic areas. We noted that this description serves well especially for tra...
