Sure. There are weaknesses in the study, it doesn't change the fact that there was a significant increase in the number of deaths.

Hiding behind the claims that studies of complex systems are not completely valid because of a lack of rigor in the process or a weakness in the data are easy to overlook when governments around the world (including mine in Canada) are routinely fudging the numbers to achieve political goals.

People are dying from climate change in record numbers, and it's going to get a lot worse, and criticizing the quality of the studies does absolutely nothing helpful.
