A recent study on some of the effects of global warming
presents some rather alarming results about the possible disappearance of more
than two-thirds of California’s plants. What makes it even worse is the fact
that the species are unique and cannot be found anywhere else in the world.
The potential floral collapse involves more than 2,000
species and without an immediate intervention, by the end of the century, the
rising temperatures and the irregular rain will lead to a significant
eco-system unbalance.
Some of the plants might have a fighting chance by migrating
to higher grounds or cooler coastal areas, but the majority will need the
researchers’ intervention for a successful relocation. The current danger areas
are at about 100 miles away from the safe cooler locations and the natural
migration process, which is extremely slow, will have to face the impediment of
the suburban areas.
The study, presented in a study released by the on-line
journal PLoS One, is the first to offer a complete presentation of a certain
area, with a detailed analysis of all the location’s compounds. Similar
studies, but far less complex, focused on certain areas in Europe, Australia,
South Africa and eastern United States.
The scientists had to gather information on more than 80,000
specimens and the process required close to five years of analyzing. The
scientists worked on eight different scenarios, with different rates of warming
and also taking into consideration the migration capacities of the species. The
timing for such an elaborate mission was considered truly adequate, as there is
still time to come up with an appropriate strategy for saving most of the
endangered species.
Another conclusion reached by the researchers is that the
disappearance of certain plants will surely affect the animals depending on
them for food, thus triggering a snow-ball effect.
One of the leaders of the study, ecologist Scott Loarie,
explained, according to the Los Angeles Times, that "The climate is
changing 10 times faster than it did during the last ice ages," and in
order to have a chance of preserving our environment, "The first thing we
need to do is to reduce the pace of change." The claim refers to the fact
that at its current rate, the climate change will lead to a large series of harmful
effects and we will be put in the situation of choosing which issue we consider
more important to focus our efforts on.
At this point, knowing the negative effects ahead with a
decent amount of time, such a selection might not be necessary, as there is
still time to come up with a successful solution for all the endangered areas.
Under the current global evolution, by the end of the
century, the temperatures worldwide will be higher with about three degrees
Celsius under an optimistic estimate and close to five degrees Celsius under a
more realistic scenario.
The people involved in the study hope that the results
released in the media will act as a wake-up call for the general public and
also for the government, as this is no longer a distant issue that begins with
the phrase "A time will come when the effects of our actions…" and
rather with "Soon, the effects…"
