The unprecedented scale of wind farm development on the coasts of Europe and America overlaps with observable climate change in the context of declining summer precipitation. In search of methods to trace this correlation and in an effort to precisely assess the impact, I chose specific locations where the phenomenon is observable in the form of altered meteorological data. Similarly to the increases in atmospheric CO2, the effect is very small, but its long-term impact will eventually lead to significant climate devastation in these densely populated areas. Minor changes are difficult to grasp. When standing on the seashore, it's not easy to notice any deviations, those must be looked for inland. My research is the first attempt of estimating the impact of the widely erected offshore wind farms, and it is being conveyed in order to start a debate on the environmental viability of such projects. Based on the analysis of meteorological data in these precisely selected European locations, I am presenting the results indicating the degrading impact of the offshore wind farms on climate in the form of inland dehydration leading to desertification in particular.
