It's not a matter of "current technology." It is a matter of the incredible physical scale of weather effects. People like to take refuge in the "theoretically possible" closet, but the reality is that possibility is controlled by feasibility. It is "theoretically possible" to move Mount Everest to Australia one spoonful at a time, but it can never happen. People aren't so stupid as to hold a planetary civilization hostage to a pipe dream.
Climate can be changed by human beings. Soviets irrigation plans for example altered not only local weather but climate patterns with the changes to the Aral sea. A climate change in a region is officially recognized when it can be consistently observed and recorded over a period of 20 to 25 years. That is not theoretical but actual evidence.
Localized weather is easier to manipulate but the effects are not long lasting.
True enough when you are diverting water drainage, to empty seas and create reservoirs. Those are big projects. But not so much when trying to tinker with the atmosphere,

The sun trumps anything humans can do, and faster.
The sun can not push light into an obscured atmosphere due to excessive volcanic activity or nuclear fall out.
We knows this because one single major volcanic eruption dropped global temperatures for a year.
