Unger says the combined effects of reduced BVOC emissions and increased albedo may have entirely offset the warming caused by the loss of forest-based carbon storage capacity.
Since forests are far greater contributors of BVOC emissions than crops and grasslands, this shift in land use has removed about 30 percent of Earth's BVOC sources, Unger said.
These impacts have also been ignored in previous climate modeling, she said, because scientists believed that BVOC emissions had barely changed between the pre-industrial era and today.
The sensitivity of the global climate system to BVOC emissions suggests the importance of establishing a global-scale long-term monitoring program for BVOC emissions, Unger noted.
By enhancing the activity of BVOC synthesising enzymes, and making it easier for such compounds to diffuse into the air, rising temperatures will cause a sharp, exponential increase in BVOCs.
BVOCs are routinely emitted by plants into the atmosphere.
While significant research has been done to assess the impact of global warming on further CO2 exchange in the atmosphere, little focus has been given to how changing temperatures will alter emissions of important compounds such as BVOCs.
Furthermore, the boreal environment is a substantial source of biogenic volatile organic compounds (BVOCs), which can affect tropospheric ozone (Atkinson and Arey 2003), and BVOCs are associated with frequent secondary aerosol formation (e.
The winter temperatures during the BAECC period were abnormally mild, with photosynthesis (net carbon uptake) persisting even in February, leading to increased emissions of BVOCs.
