Brave pioneers trekked through unknown parts of the Canadian Rockies a century ago to take photographs of the region and build the area’s first topographical maps.
Fast forward to present day and scientists are using these timeless pictures to understand how much of the landscape has evolved over the past 100 years.
The team replicated different scenes to create exact comparisons of images taken by the early mountaineers, revealing an upward creep in tree line and increased forest density – both of which are a result of climate change.
Shots of mountains in Alberta show a dramatic change in snow on the peak and tree lines on the slope, while a hilltop in the Crowsnest Forest Reserve reveals an increase in vegetation than what was present 77 years ago.
Climate science has now become utterly corrupt.
Any competent scientist would know that tree lines in the Rockies have been dropping for centuries, with the last particularly precipitate decline during the Little Ice Age.
HH Lamb included this chart in his book, “Climate, History and the Modern World”:

Fortunately the world has warmed up slightly since the 19thC, but tree lines are still much lower than in the past.
So are the authors of this latest study corrupt or simply incompetent?
