Cooling the Climate: Can we and Should we?

As reaching the Paris agreement goal of limiting the global mean surface temperature increase even below 2.00C becomes increasingly difficult, Climate Engineering is gradually gaining attention. Carbon Dioxide Removal (CDR) aims at removing CO2 from the atmosphere through techniques such as ocean fertilisation, artificial upwelling or enhanced weathering. Solar Radiation Management (SRM) directly manipulates the Earth's radiation balance by enhancing its albedo. While at least some Climate Engineering schemes could conceivably deliver a modest to significant cooling effect, Climate Engineering has been criticised for potentially dangerous side effects, distracting from the root cause of climate change (ongoing emissions), and being difficult to govern. SRM, in particular, is controversial, with opinions ranging from cautiously-favorable to proposing a downright ban on SRM-related research. So what, if any, should be the future role of CDR and SRM in the climate policy toolbox and what Climate Engineering research should have high priority?

In this session, we welcome contributions from all geoscientists and other disciplines which investigate the potential of Climate Engineering, including but not limited to:
- feasibility,
- potential to mitigate global warming or effects thereof,
- side effects and risks - environmental and otherwise, and
- governability
We particularly encourage contributions that combine scientific disciplines and work towards integrating the above topics into a broad assessment of Climate Engineering.
