The melting of the polar ice caps caused by climate change has potentially catastrophic impact beyond rising sea levels. A huge amount of solar energy is reflected back into space by these white expanses. Stephen Hawking predicted that the earth would have an atmosphere similar to Venus if we melted the ice caps. Most responses to global heating concentrate on renewable generation and, to a lesser extent, reduced consumption. We are embarking on mitigation for global warming targets that are very ambitious given the current trajectories. Our path to 1.5 degrees warming seems precarious at best and we don’t know if we have already entered feedback loops that will inexorably damage the polar ice caps. What if we could replicate the reflective effect of the polar ice caps without the need to remove CO2 from the atmosphere?
