I don't understand the claim that warming will cause drought. It seems that climate scientists are unaware or the fact that heat is required to bring moisture into the atmosphere.
 
The absence of water.
Now we're getting somewhere. Do we really need to connect the rest of the dots for you. Here, I'll get you started. Increased temperatures increase evaporation from the land and the oceans. You do know how the water cycle operates, right? Apply some engineering analysis; you'll get there.
 
There's a little more to it than that. There's a pile of water out there in the oceans (most of the earth's surface) that is also heating up. This huge pile of energy may come into play affecting climate and may cause some havoc.

Getting somewhere? I knew this 5 years ago....
 
'may' renders the entire sentence devoid of any usefulness. It means as much as This huge pile of energy may not affect climate and may not cause any havoc.

Here's the IPCC in AR6

Trends in precipitation are not a main driver in affecting global-scale trends in drought (medium confidence), but have induced increases in meteorological droughts in a few AR6 regions (NES: high confidence; WAF, CAF, ESAF, SAM, SWS, SSA, SAS: medium confidence). Increasing trends in agricultural and ecological droughts have been observed on all continents (WAF, CAF, WSAF, ESAF, WCA, ECA, EAS, SAU, MED, WCE, WNA, NES: medium confidence), but decreases only in one AR6 region (NAU: medium confidence). Increasing trends in hydrological droughts have been observed in a few AR6 regions (MED: high confidence; WAF, EAS, SAU: medium confidence). Regional-scale attribution shows that human-induced climate change has contributed to increased agricultural and ecological droughts (MED, WNA), and increased hydrological drought (MED) in some regions (medium confidence). {11.6, 11.9}

medium confidence being a coin flip, either everybody agree it should happen but there is little evidence, or half the people agree and there's some evidence, or there's loads of evidence but nobody agrees as to why it happened.

It does not seem you have figured it out yet. You indicated with your response to TugboatEng that you think warming temperatures do indeed cause an increase in droughts.
 
Fror political purposes you are right, weaselly statements are fine. But for engineering and science you need to write in a way that includes testable outcomes, so claiming that something may happen by some non specific future date is untestable, and hence not science. Or as Popper said Scientific theories are characterized by possessing potential falsifiers—that is, that they make claims about the world that might be discovered to be false. If these claims are, in fact, found to be false, then the theory as a whole is said to be falsified. Non-scientific theories, by contrast, do not have any such potential falsifiers—there is literally no possible observation that could serve to falsify these theories.
