Brian Haggerty gave a presentation
on the changing climate and how phenology is the best tool for monitoring
environmental changes from season to season and from year to year. He clarified
that the warming trends that have been observed are twice as pronounced in the
winter than in the summer, so the presumption that global warming will mean very
hot summers is incorrect. For a long time scientists have been measuring the
changes in phenology by the start of the flowering season, but, as Mr. Haggerty
has shown, the onset of flowering is only one variable in a much larger process
beginning with sprouting new growth and ending with the production of seeds.
Also, Mr. Haggerty has demonstrated how plants within the same species can be
acclimated to different elevations and will respond differently to
environmental changes. Particularly, high elevation plants have a shorter time span
between flowering and fruiting, meaning a change in environment can
disproportionally effect high elevation plants over low elevation plants,
offsetting the synchrony of flowering, and potentially disrupting the seasonal
synchrony of pollinators.
The
key concept that I took away from this lecture is that all variables must be
accounted for to understand the whole; everything is connected, and to judge a
system on one component is nonsensical. Furthermore, the solution to fix
environmental issues will not come as one large miracle solution, it will be a
compilation of many small solutions that work together; small thinks like
recycling and doing your part to live sustainably are can change the world.
