This system – Decision Information System for Managing Urban Trees or DISMUT – facilitates the development of forest-level management programs by allowing the projection of change and work requirements that the result from historical and current plantings over the entire urban forest.
The first projection of change is generated by extrapolating the rate of country-level cropland area change from 1985 to 2000 to the 2000 to 2015 time period (the country scenario).
Hence, we propose that CLIM, a projection of change in potential range extent, can act as a proxy for changes in the suitability of the climate for a given species.
It makes theoretical projections of changes in those conditions daily — and even for parts of a day — throughout the rest of the century.
Professor Enquist added that these forests appeared to be quite suseptible to changes in rainfall, and that future projections of changes in rainfall patterns were likely to have "immediate or very quick consequences".
The ability to confidently calculate hydrologic outputs at fine spatial scales provides a new suite of hydrologic predictor variables that can be used for a variety of purposes, such as projections of changes in water availability, environmental demand, or distribution of plants and habitats.
There is low confidence in projections of changes in fluvial floods due to limited evidence and because the causes of regional changes are complex.
Assessing the nature of the changes a population or system is likely to experience requires projections of changes in both climate and climate-driven processes (Baron and others 2008; Scott and others 2008).
The study, published in the online version of the Proceedings of the National Academy of Sciences, offers the most detailed projection yet of changes in California as temperatures rise around the world because of building concentrations of heat-trapping gases.
But the lead author of one of the new studies, Dr. James E. Hansen, the director of NASA's Goddard Institute for Space Studies, says there is a difference between refining projections of change and saying global warming is not a serious problem.
