The research also found that winter temperatures have more influence over tree lines than summer temperatures, a complete contradiction of established "consensus" science.
Since the trees did not advance northward as expected from global warming, this may indicate that the actual warming was overstated by other scientists. A reasonable explanation is that the trees are reacting to more moderate temperature increases than those originally claimed by warming alarmists.
"In a new research, scientists have found that treelines are not universally responding to climate warming by advancing as expected....Treelines are the elevation or latitudinal limits where trees are capable of growth or survival and are considered to be early indicators of climate warming because they are constrained primarily by cold temperatures....Summer temperature is widely considered to be the primary control of treeline formation and maintenance, whereas winter temperatures have previously been considered less critical because of the insulative effects of snow....This study reveals how winter warming has overturned this prevailing view."
