Related to this, researchers have found that higher temperatures cause more human males to survive gestation. They believe temperature acts as a stressor during pregnancy.

"The temperature coefficients (Table 1) suggest that a 1°C increase in annual temperature predicts one more male than expected for every 1,000 females born in a year. The median annual number of female births over the test period was 167,046. A rise of 1°C would, therefore, imply preservation of ≈167 males in the median year."

I still regret not buying an "I survived The Hill" shirt at Kopas store in the 80s.

No one leaves the lower parking area at Peyto. Even this view can be improved upon with some more huffing and puffing up the steep but safe slope it's on. (Not to be done in snow, however as there may be an avalanche risk.)
