Climate Scientists Recant
Only 50% Of Recent Arctic Warming & Sea Ice Loss Is Human-Caused

The Arctic region was the largest contributor to the positive slope in global temperatures in recent decades.
Consequently, the anomalously rapid warming in the Arctic region (that occurred prior to 2005) has been weighted more heavily in recent adjustments to instrumental temperature data (Cowtan and Way, 2013; Karl et al., 2015) so as to erase the 1998-2015 hiatus and instead produce a warming trend.
Meanwhile, other scientists have been busy determining that only about 50% of the warming and sea ice losses in the Arctic region is anthropogenic or connected to the rise in CO2 concentrations.
The rest of the warming and ice declines can be attributed to unforced natural variability.
Based on a short review of the peer-reviewed scientific literature, there appears to be widespread agreement that a “substantial portion” of post-1979 Arctic-wide climate changes are naturally driven.

In asserting that 50 percent of the warming is anthropological the article is dead wrong. Carbon dioxide either contributes zero or very little to warming. The best correlation is warming has followed the solar output.
50/50 is the definition of ambivalence. The worst thing an expert could say is that he doesn’t know. Collectively they seem to be saying that they don’t know.
Could it be that permanent ice is not normal, that ice caps are vestiges of calamities like asteroid strikes? Melting is healing?
Notice that humanity’s influence on temperature is always local, eg urban heat island effect. We don’t like oppressive heat but we flock to it? Texas, Florida, California and the cities. If there’s a definite human contribution to higher temperatures, it’s the expansion of concrete and roofing.
That’s a big reason why rural folk are less likely to believe in global warming .
There will always be seasons Spring,Summer,Fall and Winter and the Earth Is Not Fragile and there is No delicate Balance of Nature like Al Bore and his Earth in the Balance with his thumb on the scale
