GLOBAL CLIMATE CHANGE - Perspectives On Science, Policy, And EM HI-ED
AN ASSESSMENT OF IMPACTS OF CLIMATE CHANGE IN THE UNITED STATES A report of the U.S. Climate Change Science Program June 20, 2008
AN ASSESSMENT OF IMPACTS OF CLIMATE CHANGE IN THE UNITED STATES A joint effort of more than a dozen government agencies for the report, go online to www.usgcrp.gov
HIGHLIGHTS OF REPORT "Heat waves and heavy downpours are very likely to increase infrequency and in intensity.”
HIGHLIGHTS OF REPORT "Substantial areas of North America are likely to havemore frequent droughts of greater severity.”
HIGHLIGHTS OF REPORT “Hurricane wind speeds, rainfall intensity, and storm surge levels are likely toincrease.”
HIGHLIGHTS OF REPORT The strongest winter storms are likely to becomemore frequent,with stronger winds and more extreme wave heights."
ADDITIONAL IMPLICATIONS Soil amplification of earthquake ground shaking is likely to bemore wide spread.
ADDITIONAL IMPLICATIONS Landslides triggered in earthquakes or by flooding are likely to bemore extensive.
ADDITIONAL IMPLICATIONS The impacts oftsunami wave run upis likely to be more extensive.
PROJECTED CHANGE IN FREQUENCY “By the end of this centuryrainfall amountsexpected to occur every 20 years now could be taking placeevery five years.” y the end of this century rainfall amounts expected to occur every 20 years could be taking place every five years. Such an increase "can lead to the type of events that we are seeing in the Midwest," said Karl, though he did not directly link the current flooding to climate change.
PROJECTED CHANGE IN FREQUENCY “An increase in frequency can lead to more frequent occurrences of flooding events such as those that occurred in the Midwest during 2009 AND 2011.” y the end of this century rainfall amounts expected to occur every 20 years could be taking place every five years. Such an increase "can lead to the type of events that we are seeing in the Midwest," said Karl, though he did not directly link the current flooding to climate change.
DROUGHTS - Perspectives On Science, Policy, And Education
BOOK OF KNOWLEDGE ON DROUGHT Drought is the result of the interaction ofrainfall,which can be highly variable, andhuman systems,which can be very vulnerable to changes in rainfall.
BOOK OF KNOWLEDGE: DROUGHTS Drought is related toclimatic variabilitythat usually is occurring far from the community or the area being impacted by drought.
CAUSES OF RISK PROLONGED LACK OF PRECIPITATION LOSS OF SOIL MOSTURE LOSS OF AGRICULTURAL PRODUCTIVITY DEPLETION &POLLUTION OF GROUND WATER DROUGHTS LOSS OF VEGETATION CASE HISTORIES INSECT INFESTATION PROGRESSIVE LOSS OF LAND BY DESERTIFICATION
FACTORS THAT EXACERBATE DROUGHT RISK CLIMATE CHANGE CAUSED BY EL NINO AND LA NINA CONDITIONS (i.e., WARMING AND COOLING OF THE PACIFIC OCEAN) LOCATIONS IN SHADOW OF MOUNTAIN RANGE
EARTHQUAKES - Perspectives On Science, Policy, And Education
BOOK OF KNOWLEDGE: EARTHQUAKES Earthquakes occur as the result of interactions between and withintectonic plates in the lithospherethat are slowly converging, diverging, or sliding past each other as a result of stresses created by ongoing heat flow within the Earth.
CAUSES OF RISK INADEQUATE RESISTANCE TO HORIZONTAL GROUND SHAKING SOIL AMPLIFICATION PERMANENT DISPLACEMENT (SURFACE FAULTING & GROUND FAILURE) IRREGULARITIES IN ELEVATION AND PLAN EARTHQUAKES TSUNAMI WAVE RUNUP CASE HISTORIES LACK OF DETAILING AND CONSTRUCTION MATERIALS INATTENTION TO NON-STRUCTURAL ELEMENTS

CAUSES OF RISK HIGH VELOCITY OF INCOMING WAVES DISTANCE OF WAVE RUNUP AND RUNOFF VERTICAL HEIGHT OF WAVE RUNUP INADEQUATE RESISTANCE OF BUILDINGS TSUNAMIS FLOODING CASE HISTORIES INADEQUATE WARNING SYSTEMS PROXIMITY TO SOURCE OF TSUNAMI
FACTORS THAT EXACERBATE EARTHQUAKE RISK ENHANCED GROUND SHAKING CAUSED BY A SHALLOW FOCAL DEPTH. ENHANCED GROUND SHAKING CAUSED BY BEING IN OR CLOSE TO THE FAULT RUPTURE ZONE WHERE CONDITIONS FOR OCCURRENCE OF THE “KILLER PULSE” ARE BEST.
FACTORS THAT EXACERBATE EARTHQUAKE RISK AMPLIFICATION OF GROUND SHAKING CAUSED BY SOFT SOILS LONG--DURATION ACCELERATION PULSE CAUSED BY FLING OF THE FAULT
FACTORS THAT EXACERBATE EARTHQUAKE RISK BUILDINGS UNABLE TO WITHSTAND LATERAL GROUND SHAKING LIFELINE SYSTEMS UNABLE TO WITHSTAND PERMANENT DISPLACEMENT ASSOCIATED WITH FAULT RUPTURE, LANDSLIDES, AND LIQUEFACTION

BOOK OF KNOWLEDGE: FLOODS Flooding occurs whenthe local river channels, floodplains, wetlands, and water tables are not able to contain, store, or transmitlocal precipitation and runoff.
