Some commenters are posting partial and unrepresentive quotes from older 'extreme event' attribution studies of climate change. Extreme events in such contexts include floods, droughts, heat waves, and severe storms, most driven by increasing temperatures combined with the Clausius-Clapeyron relation between air temperature and water vapour saturation.

Two more recent reviews (both open access) indicating that a growing number of extreme events are showing the effects of anthropogenic climate change as the human signal emerges from the natural background:
