To those complaining that this research was some kind of scam to get more funding: Have you actually looked at who funded this research and what the funding was for? His funding comes from a grant to improve climate models and reduce errors, nothing directly related to aviation.
I'd also suggest that you read the original paper before you rubbish the research, y'know - so you actually know what you're talking about. The paper is available
here.
Maybe now we could get back to thinking if any of us think that the CAT encounter frequency has increased in recent years.
