New Delhi | Artificially "dimming the sun" alone will not prevent Antarctic ice sheets from melting, scientists say.

The artificial influence, which is laden with high risks and unforeseeable side effects, could prove to be an "effective tool" to slow or even prevent West Antarctic ice sheet collapse if deployed by mid-century "in a medium emissions scenario", the scientists at the University of Bern, Switzerland, estimated using modelling simulations.

The study also found that under unabated emissions and a mid-century deployment of the artificial technique, the ice sheet collapse could be delayed somewhat, but not prevented
