Striking an object causes heat. When that object vibrates it causes heat. When a human exerts themself it causes heat.
When repeated numerous times at numerous sites around the globe, well, a kitten dies and a polar bear loses its home.
X(strike) x Y (sound wave) x Z(exertion) = A(heat)
A x B(350 times) x C(number of participating congregations) = G(global warming)
So, the WCC is causing global warming.
That's not very christian.
