Ex Oil-Engineer Turned Climate Whistleblower: We Face Collapse.

The summer of 2026 will go down in history books as the hottest, driest and most deadly set of heatwaves Britain has ever experienced. This weather isn’t normal – but it is predictable according to a global consensus of scientists. And yet this summer, according to the science, will be one of the coolest summers we ever have again. Things will only get hotter from here.

Beginning his career as an oil-rig engineer before retraining as a climate scientist, Kevin Anderson’s career has been an extraordinary journey. On Downstream this week, Aaron Bastani sat down with him to discuss what has become his life’s work: sounding the alarm on man-made climate change, and on the fossil fuel industry that gave him his start.

Just how much has the planet heated, and why? Is the Paris Agreement’s aim of keeping heating to beneath 1.5°C still achievable, or delusional cope? What are the political obstacles to tackling the issue? Having worked with Andy Burnham in Manchester, what does Kevin think he will do on climate, as PM? Is avoiding catastrophe still possible, and if so, how much time have we got to act, before it’s too late?
