In the wake of the assembly of global leaders at COP26 in Scotland, scientists, politicians and activists are scrambling to come up with meaningful ways to meet the goals of carbon neutrality, and to reverse, or at least slow down the process of climate change. 

CGTN's Tech It Out Studio has invited several climate scientists to address some of the most intriguing topics on climate change, from the causes, the status quo, to the dire consequences of global warming, as well as the implications to the sustainability of humanity and that of biodiversity on planet Earth. 

Discussions will also encompass frontier science research specifically addressing the fast-evolving crisis. Guests include pioneer researcher Prof. James Hansen from Columbia University, who is best known for first sounding the alarm of global warming in the 1980s, and two Chinese climatologists who both lead in their respective domains of research.
