Geoengineering, also known as ‘climate intervention’  is being debated by the UK government on 23rd June 2025. This is a response to a petition signed by ~160k people calling for a ban on geoengineering in the UK.

I have been conducting interviews on this topic for the last 15 years. In that time, the climate science data has gotten worse and worse. Successive governments around the world have failed to properly regulate in order to phase out carbon emissions from the fossil fuel industry and land use sectors, that make up the main bulk of pollution.

The outcomes we face are regarded by many scientists as existential around the world and the question of geoengineering as a response polarises climate scientists, experts, and many others involved in this space.

This sequence of edits taken from my interviews between 2012 and 2025 features many leading scientists and commentators on both sides of the argument. 

The main focus of this video is a type of geoengineering called solar radiation modification or SRM. Within this there are different proposals. One mentioned here is stratospheric aerosol injection, or SAI, and Marine Cloud Brightening, MCB. These techniques aim to reduce the amount of the suns energy that reaches the earth’s surface, thereby helping to cool the planet while efforts continue to reduce carbon emissions worldwide. 

Please watch and post your own thoughts and comments below. I have created a very short survey on the genn.cc website where you can state your position and response to this sequence.

Please note that I have included the years in which these interviews were recorded in each segment, although they are not presented in chronological sequence. What this shows is the huge inertia in this topic while the background noise of catastrophic climate impacts has been moving into the foreground. 

Thank you for watching. Please do consider subscribing to Climategenn or even better, become a member. I will be posting all these interviews into the members area on Youtube and Patreon. Many are already in the public domain.
