What could possibly go wrong?

The Daily Mail reports:

István Szapudi, an astronomer from the University of Hawai?i, argued his far-fetched concept was merely an enormous 'solar shield'.

The shield – which would be made of the ultra strong 'wonder material' graphene – would block energy from the sun and cool down our planet. 

Szapudi's paper on the subject has been published by Proceedings of the National Academy of Sciences.

"In Hawai?i, many use an umbrella to block the sunlight as they walk about during the day," Szapudi said, adding "I was thinking, could we do the same for Earth and thereby mitigate the impending catastrophe of climate change?"

Genius.
