Summary:

- The renowned climate scientist James Hansen states that the global target of limiting warming to 2°C above pre-industrial levels is now "essentially impossible" to achieve.
- Hansen argues that the current climate policies and commitments are insufficient to meet this goal, and that much more drastic action is needed to avoid the worst impacts of climate change.
- He emphasizes the urgent need for a rapid transition to renewable energy sources and the implementation of policies that can effectively reduce greenhouse gas emissions on a global scale.
