S1E81: Taking the heat out of climate change with CO2 removal

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.

removal measures?
