(Prof. Jennie C. Stephens is professor of climate justice at National University of Ireland, (Maynooth ) & Co-convenor of the Climate Justice University Union who wrote an article for The Irish Times, 21st May, 26., on data centres supporting AI.)
The big tech companies are reaping huge profits from AI. She said governments & big tech do not want us to learn about its disastrous climate impacts i.e. expansion of data centres. The data processing involved in every AI application requires huge data centres powered by fossil fuels. AI & its data centres are increasing its usage of fossil fuels when it should be phasing out. This energy demand is impacting & accelerating climate chaos despite climate policy which has been designed to reduce both energy use & carbon emissions.
Some data centres are powered by renewable energy instead of fossil fuels. instead of fossil fuels. It is the energy demand which is destabilising energy systems, creating more energy poverty & exacerbating climate problems among the most vulnerable.
The explosive growth of data centres globally has eliminated the possibility of meeting the legally binding commitments of the international Paris Agreement. The tech companies such as Amazon, Google, Microsoft, Meta, Open AI & Anthropic downplay ecological impacts of their data centres & invest in policies to delay regulation aimed at protecting ecological health & the public at large. These tech companies are partnering with fossil fuel companies to develop AI to extract more fossil fuels quicker & cheaper. Data centres use hugh amounts of electricity in warehouse-like buildings. They also use huge amounts of water for cooling. It contributes to biodiversity loss as well as community dis-connection.
Our governments encourage us to embrace AI tools etc. However, resistance is growing around the world. Staff & students in higher education institutions faculties within the Climate Justice Universities Union are challenging the narrative of rejection the 'uncritical adoption of AI in teaching, learning & research'. Prof: Stephens continues to say 'communities are organising to block new data centres'. Journalists are calling out AI harms. Civic society organisations including Friends of the Earth, An Taisce, (Ireland) & others, are calling for a data centre moratorium & a pivot in national priorities away from big tech & fossil fuels. Prof: Stephens mentions Fintan O'Toole, Irish Times Journalist, who called on people to join the 'resistance' at a Trinity College, Dublin event. 😎🇨🇮🏴
