Sea levels will rise and destroy tons of cropland and houses, and this will cause mass migration to actual livable areas combined with a lack of food production. It will likely turn into a bloodbath.Literally impossible for a planet to grow both warmer and more arid without like, blasting off huge chunks of the ocean and atmosphere into space*.
Deserts reach their largest extent during the peaks of ice ages, they retreat and disappear during the warmest parts of interglacials.
*smashing a large enough chunk of rock (or smaller chunk at sufficient velocity) would definitely raise the temperature of all locations near the surface while doing away with all that wet stuff nicely
The planet doesn't need to become more arid. It just needs to have the water redirected to somewhere else. If the heat rises in an area, water will evaporate faster. Plants will die. And when the plants die, the soil loses it's ability to hold water and resist wind. Plants can't grow in it as easily. So the edges of forests and jungles will slowly make way to desert.
