Climate Change."

"Climate change is not a new topic in biology. The study of
biological impacts of climate change has a rich history in the
scientific literature, since long before there were political
ramifications ..... Observations of range shifts in parallel with
climate change ... date back to the mid-1700s."
"A surprising result is the high proportion of species responding to
recent, relatively mild climate change (global average warming of
0.6C). The proportion of wild species impacted by climate change was
estimated at 41% of all species (655 of 1598)."

Nature 2 August 2007
"Which ecosystems are we talking about?
All of them, but climate change will affect them in different ways."
"What responses to climate change are actually documented?
In the Northern Hemisphere, the range of terrestrial plants and
animals has shifted, on average, 6.1 km per decade northward or 6.1 m
per decade upwards, with advance of seasonal phenomena by 2.3-5.1
days per decade over the past 50 years. These changes are
significantly correlated with measured changes in temperature and
precipitation. The relationships are correlative in essence, but are
too robust, numerous and consistent to be random or to have arisen
from other factors (such as natural climatic variability or land-use
change). Similarly, the remarkable increase in the plant diversity of
some high-elevation peaks in Switzerland over the past 100 years,
owing to the upward shift of species that traditionally inhabited
lower elevations, can be attributed to changed climate regimes."
