They will do that by taking a close look at restrictions on building in hazardous coastal areas, making coastal
structures more storm - proof, protecting and enhancing coastal wetlands and other
ecosystem features that can buffer storm
impacts, and creating financial incentives to promote protective behaviors.
Jerry's research team has developed and uses a simulation model, the Terrestrial
Ecosystem Model (TEM), to consider the
impacts of various aspects of global change — climate, chemistry of the atmosphere and precipitation, land cover and land use — on the
structure and function of terrestrial
ecosystems across the globe.
Relatively rapid degradation of ice - rich permafrost is adversely affecting human infrastructure, altering Arctic
ecosystem structure and function, changing the surface energy balance, and has the potential to dramatically
impact Arctic hydrological process and increase greenhouse gas emissions.
Degradation of near - surface permafrost (perennially frozen ground) caused by modern climate change is adversely affecting human infrastructure, altering Arctic
ecosystem structure and function, changing the surface energy balance, and has the potential to dramatically

The direct CO2 - fertilisation
impact and warming effect of rising atmospheric CO2 have contrasting effects on their dominant functional types (trees and C3 grasses may benefit from rising CO2 but not from warming; C4 grasses may benefit from warming, but not from CO2 - fertilisation), with uncertain, non-linear and rapid changes in
ecosystem structure and carbon stocks likely.
However, changes in pH in coastal
ecosystems result from a multitude of drivers, including
impacts from watershed processes, nutrient inputs, and changes in
ecosystem structure and metabolism.
This new concept of anthropogenic
impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in coastal
ecosystems, including changes in land use, nutrient inputs,
ecosystem structure and net metabolism, and emissions of gases to the atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated coastal systems, where OA by anthropogenic CO2 is the dominant mechanism of anthropogenic
impacts on marine pH, to coastal
ecosystems where a range of natural and anthropogenic processes may operate to affect pH.
Accordingly, there are three main vectors of anthropogenic
impacts on marine pH: (1) emissions of CO2, and other gases affecting marine pH, to the atmosphere; (2) perturbation of watershed processes affecting the inputs of nutrients, organic and inorganic carbon, acids and carbonate alkalinity to the ocean; and (3)
impacts on
ecosystem structure (Table 1).
