Global Warming Increasing The Dispersal Of Flora In Northern Forests
ScienceDaily (June 12, 2009) — As a result of stronger winds caused by
global warming, seeds and pollen are being carried over longer
distances. An increase in temperature of only a couple of degrees may
increase the dispersal of plants in Northern forests and the spread of

Off hand, I'd guess that a warming earth would result in a smaller
temperature gradient between equator and poles, resulting in LESS
wind.
If wind has been spreading polling further, that's a sign that the
temperature gradient has been increasing, and temperatures have been
dropping.
Note how the above story contradicts the following:

"Global warming reduces available wind energy

A switch to wind energy will help reduce greenhouse gas emissions --
and reduce the global warming they cause. But there's a catch, says
climate researcher Diandong Ren, a research scientist at the
University of Texas at Austin in a paper appear in the AIP's Journal
of Renewable and Sustainable Energy: rising temperatures decrease wind
speeds, making for less power bang for the wind turbine buck. The
prevailing winds in the "free" atmosphere about 1,000 meters above the
ground are maintained by a temperature gradient that decreases toward
the poles. "For example, Wichita, Kansas is cooler, in general, than
Austin, Texas," Ren says. "The stronger the temperature contrast, the
stronger the wind." But as the climate changes and global temperatures
rise, the temperature contrast between the lower latitudes and the
poles decreases slightly, because polar regions tend to warm up
faster. And as that temperature contrast becomes weaker, so too do the
winds. "
