In this episode Nick Breeze speaks with Dr Soumitra Das from the Healthy Climate Initiative. Soumitra sheds light on the life threatening challenges that face citizens in India and surrounding countries today. A major threat to life is when heat and humidity combine – known as wet bulb temperatures. This is when the body is unable to cool itself, leading to fatal heatstrokes within a few hours. Today 2% of India’s population are exposed to wet bulb extremes. In a country nearing 1.5 billion people, 2% equates to ~around 30 million people. On the current trajectory this figure is set to rise by midcentury to 70%, or, in real terms, in excess of 1 billion citizens at risk of heatstroke.The fossil fuel industry is the main culprit of this ongoing rise in temperatures, doing everything they can to slow the inevitable transition to clean renewable energy. The impact on peoples lives, infrastructure, biodiversity on land and in the oceans, is incalculable, as carbon emissions continue to rise. All of this is set against the needlessly worsening relations between humans around the world. New episodes include interviews with Professor Mark Maslin at UCL about the state of what the recent World Meteorological Organisation Climate Report tells us and his views on whether we should be looking into methods to cool the earth while we continue to try and reduce emissions. Nick also catch's up with Dr René van Westen at Utrecht University about his and his colleagues new AMOC research paper. The research tells us more indications of Europe’s dramatic climate future as the global mean temperature rises over 2ºC. This is inline with our current emissions scenarios that scientists have told us we should avoid at all costs. Currently our emissions trajectory is taking us much much higher and raises hard questions about the future we want to try and exist in.

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.

Zack is well known on social media for his engaging graphics that tell the climate change story. He also played a pivotal role at the US National Oceanic Atmospheric Association, or NOAA, in advancing climate modelling and forecasting through innovative AI and machine learning approaches. His forced departure, along with hundreds of other scientists due to DOGE-led federal cuts, has significantly undermined NOAA’s research capacity. The loss not only stalls progress in critical climate science but also poses real risks to public safety and the global understanding of climate change.
