净零排放与能源转型

评估实现净零排放所需的能源转型：可再生能源规模化、交通运输和供热电气化、绿氢；描述碳捕集与封存和直接空气捕集；介绍拟议的太阳辐射管理技术（平流层气溶胶注入、海洋云增亮）及其潜在风险和治理挑战；批判性评估个人行为改变与系统性政策在减排中的作用。

Evaluate the energy transition required to reach net zero: renewable energy scaling, electrification of transport and heat, green hydrogen; describe carbon capture and storage (CCS) and direct air capture (DAC); introduce proposed solar radiation management techniques (stratospheric aerosol injection, marine cloud brightening) and their potential risks and governance challenges; critically evaluate the role of individual behaviour change versus systemic policy in reducing emissions

Has {{name}} heard of geoengineering? Can they describe one proposal for deliberately cooling the Earth and explain one potential risk of attempting it — and say whether they think individuals or governments bear more responsibility for tackling climate change?
