According to leading climatologists and plant scientists, the Earth will become more fragrant as it grows warmer. Apparently, the higher temperatures will lead plants to produce more aromatic chemicals. From BBC Earth News:
Climate change will make the world more fragrant.
As
CO2 levels increase and the world warms, land use, precipitation and
the availability of water will also change.In response to all
these disruptions, plants will emit greater levels of fragrant chemicals
called biogenic volatile organic compounds.That will then alter
how plants interact with one another and defend themselves against
pests, according to a major scientific review.According
to the scientists leading the review, the world may already be becoming
more fragrant, as plants have already begun emitting more smelly
chemicals.“The increase is exponential,” says Professor Josep
Penuelas, of the Global Ecology Unit at the Autonomous University of
Barcelona, Spain.“It may have increased already by 10% in the
past 30 years and may increase 30 to 40% with the two to three degrees
(Celsius) warming projected for the next decades.”
