Less ice on rivers, lakes and the sea will lead to more evaporation, probably increasing cloud cover at mid-levels, which should have a cooling effect.

Svensmark then teamed up with Friis-Christensen to review solar activity, cloud cover and cosmic ray levels recorded using satellite data available since 1979.

His (as yet unpublished) research confirms, he says, that the variations in cloud cover seen by satellites match those in cosmic-ray flux better than anything else, such as the sun's total brightness.

Tim Bresnan was the most successful bowler, taking 2-47 as England made the most of overhead cloud cover and a pitch offering some seam movement.

The cloud cover associated with rainforests makes Sar something of a game-changer in that sense, allowing repeat viewing of an area on a frequent basis whatever the weather.

Instead of scheduling a plane, which could take longer owing to the time required to make arrangements with the local airport, drones would be lower-cost and able to operate even if there was cloud cover, he said.

Much of the cloud cover visible at the start of play quickly dispersed and Cook hit his first ball - a weak Johnson loosener - for four.
