"You can't cover the sun with a finger", but maybe with science and technology yes. According to Forbes , Bill Gates is funding a project that would dim sunlight in order to "cool" the Earth.

The research called " Stratospheric Controlled Disturbance Experiment " (SCoPEx for its acronym in English) is carried out by scientists from Harvard University and has the purpose of achieving that the sunlight is reflected outside the atmosphere of our planet.
