I assume all precipitation changes lead to net damages as they cause shifts relative to traditional patterns to which human systems are aligned.
Not exact matches
Since the evapotranspiration rates of the study's cropping systems held steady across several years of varying
precipitation levels, the study also suggests that crop evapotranspiration rates may not be as sensitive to climate
change as is currently
assumed.
ACPI
assumes a 1 percent annual increase in the rate of greenhouse gas concentrations through the year 2100, for little
change in
precipitation and an average temperature increase of 1.5 to 2 degrees centigrade at least through the middle of 21st century.
Quantitation is one of the elements Trenberth discusses in the piece I quoted (e.g., a percent
change in
precipitation), and is relevant in that some of this thread had
assumed that Trenberth was proposing a new null hypothesis with no quantitative aspects.
Maps show projected percent
change in
precipitation in each season for 2071 - 2099 (compared to the period 1970 - 1999) under an emissions scenario that
assumes continued increases in emissions (A2).
The assistence of higher resolution projections to the vulnerability assessment of Amsterdam may lie in the analysis of consequences of an
assumed sea level
change on the probability that a major storm or inland
precipitation event (or a combination of these) lead to water levels that are disruptive for the city.
Projected
change in seasonal
precipitation for 2071 - 2099 (compared to 1970 - 1999) under an emissions scenario that
assumes continued increases in emissions.
Consequently,
assuming mild greenhouse gas emission scenario (RCP2.6), areal extent of the conditions suitable for the processes in the study areas can contract 70 % by 2050 owing to
changes in average air temperature and
precipitation.
The same should be true for climate
change we should evaluate the
changes in temperature (not anomalies) over time at the same stations and present the data as a spaghetti graph showing any differing trends and not
assume that regional or climates in gridded areas are the same — which they are not as is obvious from the climate zones that exist or microclimates due to
changes in
precipitation, land use etc..
This
assumes that there are no
changes in demographics,
precipitation, storm surges or adaptation.
