What's climate change ruining today?

Okay, sure, jet travel accounts for 2% of global greenhouse gas emissions (this is situation where a small percentage is actually a really big number, fyi). So this is maybe more ironic than tragic, but it turns out that some scientists think changing climates could have an effect on air turbulence. Specifically, one model suggests it will increase the ferocity and frequency of surprise areas of turbulence that pilots can't see coming.
