They have an FAQ
on their website addressing the environmental impacts of the drug, claiming that once the drug is digested, it is no longer available to another bird, and also that it has very poor
water solubility, and degrades safely in soil.
There are many things about climate that I accept — that human emissions have effect
on increases of CO2 content in the atmosphere (while the concentration is driven largely by temperature and resulting
solubility of CO2 in sea
water, humans still provide the surplus), that this increased CO2 content has effect
on temperature (and indirectly
on other aspects of climate), that humans affect the climate (but not just through CO2 but also through UHI, agricultural changes, pollution etc), that temperatures have risen since half of the last century.
Topics that I work
on or plan to work in the future include studies of: + missing aerosol species and sources, such as the primary oceanic aerosols and their importance
on the remote marine atmosphere, the in - cloud and aerosol
water aqueous formation of organic aerosols that can lead to brown carbon formation, the primary terrestrial biological particles, and the organic nitrogen + missing aerosol parameterizations, such as the effect of aerosol mixing
on cloud condensation nuclei and aerosol absorption, the semi-volatility of primary organic aerosols, the importance of in - canopy processes
on natural terrestrial aerosol and aerosol precursor sources, and the mineral dust iron
solubility and bioavailability + the change of aerosol burden and its spatiotemporal distribution, especially with regard to its role and importance
on gas - phase chemistry via photolysis rates changes and heterogeneous reactions in the atmosphere, as well as their effect
on key gas - phase species like ozone + the physical and optical properties of aerosols, which affect aerosol transport, lifetime, and light scattering and absorption, with the latter being very sensitive to the vertical distribution of absorbing aerosols + aerosol - cloud interactions, which include cloud activation, the aerosol indirect effect and the impact of clouds
on aerosol removal + changes
on climate and feedbacks related with all these topics In order to understand the climate system as a whole, improve the aerosol representation in the GISS ModelE2 and contribute to future IPCC climate change assessments and CMIP activities, I am also interested in understanding the importance of natural and anthropogenic aerosol changes in the atmosphere
on the terrestrial biosphere, the ocean and climate.
