Being wrong is a feature, not a bug

We don't think that selection has been strong enough to completely fine-tune the adaptation of individual human populations to their local environments."

The researchers found that many previously identified genetic signals of selection may have been created by historical and demographic factors rather than by selection.

Selection may still be occurring in many regions of the genome, says Pritchard. But if so, it is exerting a moderate effect on many genes that together influence a biological characteristic

These patterns suggest that selection is often weak enough that neutral processes—especially population history, migration, and drift—exert powerful influences over the fate and geographic distribution of selected alleles.

And all these numbers should be views considering the fact that in 2005 the total number of candidates were 7 compared to 4 this time. So some numbers such as candidates share of vote in their home city and province should be readjusted. In the Lorestan province, Karoubi went from having 9 times vote more than Ahmadi Nejad in 2005 to 1/15th of his vote this time,a 135 times change in the ratio, even considering this difference in the number of candidates.

He emphasized that  “the [current] status quo is unsustainable.”

The study clearly suggests the question: what would be the impacts and consequences, for the United States and worldwide, of a 21st century warming of the magnitude projected with this new modeling work?  For sea level rise and melting ice? For freshwater availability and disruption of water resources? For hurricanes and other extreme weather and climate events? For agriculture and food security? For managing ecosystems and the potential for species extinctions? For human health? For the economy of the United States? For the economies of developing countries?
