Cloud-seeding experiments
The article ‘Malta becoming too dry to support its habitat’ (May 2) predicts that our islands are turning into a desert because of the continuing rainfall shortage. This is a dire prospect for the agricultural sector and would be very detrimental to our green environment.
On a number of days during the ‘rainy’ seasons our sky is quite cloudy but we often remain without rainfall. Facing similar occurrences, various countries are resorting to cloud seeding, with varying degrees of success.
This seeding involves spraying certain substances, such as dry ice, which already exists in the atmosphere, into the clouds by means of aircraft or rocket to induce the water vapour inside them to fall as rain or snow.
