Sentences with phrase «terrestrial carbon led»

Ignoring terrestrial carbon led to a nearly complete loss of unmanaged forests by 2100, largely because they were replaced by massive expansions of bioenergy crops that were planted to reduce the use of fossil fuels.

Not exact matches

However, placing a value on terrestrial carbon emissions led to increased forest cover, while bioenergy use still increased considerably compared to today.

Bailey currently leads a PNNL research project for DOE's Terrestrial Ecosystems Sciences program that focuses on understanding and modeling the mechanisms of carbon stabilization in soil, and associated greenhouse gas fluxes.

«This graph gives you an idea of what the Anthropocene climate looks like as... without even taking into account the possibility of carbon cycle feedbacks leading to a release of stored terrestrial carbon.»

We introduce a carbon cycle model that would explain the PETM by global warming following a bolide impact, leading to the oxidation of terrestrial organic carbon stores built up during the late Paleocene.

Dull, et al, argue that the re-growth of Neotropical forests following the Columbian encounter led to terrestrial biospheric carbon sequestration on the order of 2 to 5 GtC, thereby contributing to the well - documented decrease in atmospheric C recorded in Antarctic ice cores from about 1500 through 1750.

The long - term potential predictability of soil water variations in combination with the slow regrowth of vegetation after major disruptions leads to enhanced predictability on decadal timescales for vegetation, terrestrial carbon stock, and fire frequency, in particular in the Southern United States (US) / Mexico region.

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.
