Can you show a link from a credible source that proves that claim? The link you provided only covers cloud seeding in Texas, which does make the point about humans changing the weather. Realize Lake Erie and Lake Ontario both head to the North-East which increases in distance over most of the PA Turnpike. In addition, you have the mountain range between the lakes and the turnpike. You also have I90 and I80 stretching south of the lakes. The lakes, themselves, do have an effect on the climate of the nearby terrain, but peters out the further south you get from the lakes. When I90 was constructed through Western NY, North-West PA and Eastern Ohio, people claimed it made a greater snowfall on the south side of the highway, but, in actuality, there was no difference as the warmth of the lake, in early winter, reduces the amount of snow right along the lake for a short distance and can drop quite a bit of snow a mile or two south of the lake, this has occurred for years. A lot of those claims were due to faulty memories.Really? U sure? In Pa, they laid down the Pa Turnpike starting in 1940. After it was done, there was a dramatic drop in lake effect snow from the great lakes, south of the highway.
The turnpike created a huge crosswind that lowered lake effect snowfall south of it as much as 40% at times. Permanently. They didn't even know they were doing it.
Note, I am not disputing climate change, which is a natural phenomenon regardless of what life may or may not add to it. It was just about 12,000 years ago that ice/snow covered a significant portion of the Northern Hemisphere and created the Great Lakes when it melted. And prior to that period of ice, there was a different climate in the Northern Hemisphere. A study done using Hawaii's Mauna Kea indicated 3 glacial periods from 150,000-200,000 years ago.
