Synopsis: Every first and third Monday of the month, The Straits Times analyses the beat of the changing environment, from biodiversity conservation to climate change.

With each passing year, more and more carbon dioxide is pumped into the atmosphere, raising the global temperature. The race is now on to rapidly cut carbon emissions to limit the pace of global warming. But it’s clear that more will need to be done. Huge amounts of CO2 will also have to be removed from the atmosphere, alongside slashing fossil fuel use and ending deforestation.

In this episode, The Straits Times’ environment correspondent Audrey Tan and climate change editor David Fogarty discusses the growing importance of CO2 removal technology with Dr Oliver Geden, Senior Fellow at the German Institute for International and Security Affairs and a lead author for the UN's top climate science body, the Intergovernmental Panel on Climate Change, or IPCC.

Dr Geden is an expert on CO2 removal methods and he explains some of the different types and costs and why planting trees alone will not be enough.

1:23 What is carbon dioxide removal?

3:07 Why is planting trees alone simply not enough?
