It must be said, though not necessarily endorsed, that there are those who
question climate change. Despite the summers
which have been quite warm, the winters that have been curiously cold
and mercurial, the increase in strange natural disasters across the
globe (was that a tornado in Brooklyn
?) the graphs
plotting average global temperature over the last century or so that
look like the profit charts for the most ambitious investment bank,
there are those
who have their own research and data to suggest global
warming is not really happening.
today has a much simpler example of how global warming is not only
apparent, but visible to the naked, unscientifically-inclined eye: tawny
owls are turning brown as a result of a warming climate, according to
scientists in Finland. A study carried out over thirty years and
published recently in the journal Nature Communications
showed that while grey tawny owls had higher survival rates in colder
environments, brown owls were becoming more common.
Dr. Patrik Karell from the University of Helsink, the leader of the
journal study, tells the BBC that they've gone from around 30 percent of
the tawny population in Finland to around 50 percent, despite the fact
that the grey color trait is the dominant gene when mixed.
brown owl's "survival has improved as winters have become warmer," says
the Dr. Karell, as quoted in the BBC. "...climate-driven selection has
led to an evolutionary change in the population."
Somebody probably has a
counter-chart that shows the opposite. But do they have a counter owl?
