Not 'chemtrails' per se but there's currently 'cloud seeding' operations currently over the gulf region creating heavy rains in Iran and adjacent Arab states
in other news Israel (and verified by UNFIL.) has been spraying glyposate over areas of Syria and Lebanon (a modern day 'salting the earth' !)

There are absolutely weather modification programs being done in various places, including the US, but not secretly dispersed worldwide by commercial jet airliners on behalf of shadowy world organisations. There's a lot of heavy lifting being done to get from A to B here.There is a difference between Cloud seeding type operations and the Chemtrail Conspiracy theory BS.
