HC Deb 14 May 1963 vol 677 c142W
59. Mr. Dan Jones

asked the Secretary of State for Air what recent estimate has been made by Her Majesty's Government of the effect of nuclear bomb testing upon the weather; and if he will make a statement.

Mr. H. Fraser

No such estimate has been made.

There is no reason to think that nuclear bomb testing has at any time had a significant effect upon the weather. Local releases of energy greater than those caused by man-made explosions are always taking place in the atmosphere. For example, in the tropics there are between 1,000 and 2,000 thunderstorms in progress at any time, each releasing the same energy as a megaton bomb.
