New Study: Globally, 30% Of Modern Forests Have Not Warmed…50% Of Treelines Have Not Advanced
By Kenneth Richard on 20. January 2025
Scientists presumably intending to report unusual modern warming in response to anthropogenic activities actually indicate all or nearly all modern warming and treeline advances at a Rocky Mountain ice patch site occurred from the 1910s to the 1940s.
An interesting observation found in the body of a new study (Pederson et al., 2025) is that 30% of the globe’s forests have not even warmed in the modern era (1900s-present), and just 50% of the globe’s forests have not advanced upslope. This would appear to challenge claims of global-scale warming.
“Variations in local conditions likely explain why recent warming documented at approximately 70% of treelines globally only resulted in ~50% exhibiting upslope advances.”
The study documents a millennia-scale treeline and temperature record from a high-elevation site (>3,000 m above sea level) in the USA’s Rocky Mountains (Yellowstone region).
