Yes, human-caused climate change is leading to more intense and frequent strong wind events, particularly in hurricanes, where warmer oceans fuel more powerful storms with stronger winds and heavier rain. While the specific impact on average wind speeds is complex and a subject of ongoing research, there is strong evidence that climate change is accelerating upper-level jet stream winds and contributing to more powerful, localized gusts, such as those in derechos and freak wind gusts, which increase risks for infrastructure and travel.  
How Climate Change Affects Wind
Warmer ocean temperatures provide more energy for hurricanes, leading to increased wind speeds and heavier rainfall, making storms more destructive. 
The upper-level jet stream is expected to speed up significantly with a warming climate, increasing by about 2% for every degree Celsius of warming. 
Climate change is contributing to stronger, more localized wind gusts, such as those seen in extreme events like the 2020 derecho and other severe thunderstorms. 
These increased wind speeds and gusts pose dangers for infrastructure, power lines, and air travel, as well as contributing to risks like wildfires and storm surges. 

Complexity and Uncertainty
  • Mixed Global Trends:
    While strong winds from extreme events are increasing, the overall global trend for average surface wind speeds is more complex. A phenomenon known as "global stilling" initially showed winds slowing, but a 2019 study indicated a reversal around 2010, with land-based global wind speeds increasing since then. 

Implications
While faster winds could benefit wind energy production, changing patterns and increased storm intensity also pose challenges for turbine infrastructure. 
Increased wind intensity necessitates more resilient building codes and infrastructure designed to withstand high winds and flying debris. 
Better analysis and tracking of wind data, alongside community awareness and adaptation planning, are crucial to address the increasing risks associated with wind-related extreme events.
