Sentences with phrase «future atmospheric aerosol»
It is my understanding that the uncertainties regarding climate sensitivity to a nominal 2XCO2 forcing is primarily a function of the uncertainties in (1) future atmospheric aerosol concentrations; both sulfate - type (cooling) and black carbon - type (warming), (2) feedbacks associated with aerosol effects on the properties of clouds (e.g. will cloud droplets become more reflective?)

Mission leaders were relieved and eager to begin their studies of cloud and haze effects, which «constitute the largest uncertainties in our models of future climate — that's no exaggeration,» says Jens Redemann, an atmospheric scientist at NASA's Ames Research Center in Mountain View, California, and the principal investigator for ObseRvations of Aerosols above CLouds and their IntEractionS (ORACLES).
Non-polar glacial ice holds a wealth of information about past changes in climate, the environment and especially atmospheric composition, such as variations in temperature, atmospheric concentrations of greenhouse gases and emissions of natural aerosols or human - made pollutants... The glaciers therefore hold the memory of former climates and help to predict future environmental changes.
With her colleagues from around the world, she is designing techniques to better characterize complex molecules in biological samples, atmospheric aerosols, and biofuels, work critical for a secure energy future.
Differences in future atmospheric burdens and radiative forcing for aerosols are dominated by divergent assumptions about emissions from South and East Asia.
Future emails will include: the difference between contrails / vapour trails and Stratospheric Aerosol Injection observations on covert atmospheric spraying (their tactics have changed in the last few weeks — this has been noticed globally) who is controlling the spraying — who are «they» much of the northern hemisphere is burning — California, Canada, Siberia (2,000 mile smoke clouds), Sweden etc..
As the Director of GISS and Principal Investigator for the GISS ModelE Earth System Model, I am interested in understanding past, present and future climate and the impacts of multiple drivers of climate change, including solar irradiance, atmospheric chemistry, aerosols, and greenhouse gases.
Models that attempt to perform reliable projections of future climate changes should account explicitly for the feedbacks between climate and the processes that determine the atmospheric concentrations of greenhouse gases, reactive gases and aerosol particles.
