https://www.ipcc.ch/sr15/chapter/spm/You're linking the 1.5 degrees warming report, which is already known to be an impossible target, the warming we'll reach if we stop carbon emissions completely by 2050; 2 degrees is the new target. We are nowhere near to being on track for such a goal, so you should actually look at the 3+ degrees predictions.
I should admit that I was somewhat wrong to bring up droughts - the report is much more concerned with flooding. I also forgot one of the most catastrophic predictions - the melting of the polar ice caps and resulting ocean level increase - but I suppose that's also a net positive in your book, somehow.
Regarding the increased frequency of extreme weather, the reports are again very clear [0]:
> It is virtually certain that hot extremes (including heatwaves) have become more frequent and more intense across most land regions since the 1950s, while cold extremes (including cold waves) have become less frequent and less severe, with high confidence that human-induced climate change is the main driver14 of these changes. Some recent hot extremes observed over the past decade would have been extremely unlikely to occur without human influence on the climate system. Marine heatwaves have approximately doubled in frequency since the 1980s (high confidence), and human influence has very likely contributed to most of them since at least 2006.
> It is likely that the global proportion of major (Category 3–5) tropical cyclone occurrence has increased over the last four decades, and it is very likely that the latitude where tropical cyclones in the western North Pacific reach their peak intensity has shifted northward; these changes cannot be explained by internal variability alone (medium confidence).
> Human influence has likely increased the chance of compound extreme events18 since the 1950s. This includes increases in the frequency of concurrent heatwaves and droughts on the global scale (high confidence), fire weather in some regions of all inhabited continents (medium confidence), and compound flooding in some locations (medium confidence).
