This study assesses how human-induced climate change has altered the likelihood and intensity of the July event or similar events. It uses a large number of climate simulations that were available at the time of study (8 ensembles of 10 to over 100 simulations each).

Prenatal exposure to methylmercury (MeHg) and polychlorinated biphenyls (PCBs) has been associated with impaired performance on attention tasks in previous studies, but the extent to which these cognitive deficits translate into behavioral problems in the classroom and attention deficit/hyperactivity disorder (ADHD) remains unknown.
