Book of knowledge on climate change
BOOK OF KNOWLEDGE ON CLIMATE CHANGE


An assessment of impacts of climate change in the united states

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 states1

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
HIGHLIGHTS OF REPORT STATES

"Heat waves and heavy downpours are very likely to increase infrequency and in intensity.”


Highlights of report1
HIGHLIGHTS OF REPORT STATES

"Substantial areas of North America are likely to havemore frequent droughts of greater severity.”


Highlights of report2
HIGHLIGHTS OF REPORT STATES

“Hurricane wind speeds, rainfall intensity, and storm surge levels are likely toincrease.”


Highlights of report3
HIGHLIGHTS OF REPORT STATES

The strongest winter storms are likely to becomemore frequent,with stronger winds and more extreme wave heights."


Additional implications
ADDITIONAL IMPLICATIONS STATES

Soil amplification of earthquake ground shaking is likely to bemore wide spread.


Additional implications1
ADDITIONAL IMPLICATIONS STATES

Landslides triggered in earthquakes or by flooding are likely to bemore extensive.


Additional implications2
ADDITIONAL IMPLICATIONS STATES

The impacts oftsunami wave run upis likely to be more extensive.


Projected change in frequency
PROJECTED CHANGE IN FREQUENCY STATES

“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 frequency1
PROJECTED CHANGE IN FREQUENCY STATES

“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 STATES

- Perspectives

On Science, Policy,

And Education


Book of knowledge on drought
BOOK OF STATESKNOWLEDGE 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 droughts1
BOOK OF KNOWLEDGE: DROUGHTS STATES

Drought is related toclimatic variabilitythat usually is occurring far from the community or the area being impacted by drought.


CAUSES OF RISK STATES

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
FACTORS THAT EXACERBATE DROUGHT RISK STATES

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 STATES

- Perspectives

On Science, Policy,

And Education


Book of knowledge on earthquakes
BOOK OF STATESKNOWLEDGE ON EARTHQUAKES


Book of knowledge earthquakes
BOOK OF KNOWLEDGE: EARTHQUAKES STATES

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 STATES

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


TSUNAMIS STATES

- Perspectives

On Science, Policy,

INADEQUATE WARNING SYSTEMS

PROXIMITY TO SOURCE OF TSUNAMI




Factors that exacerbate earthquake risk
FACTORS THAT EXACERBATE EARTHQUAKE RISK STATES

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 risk1
FACTORS THAT EXACERBATE EARTHQUAKE RISK STATES

AMPLIFICATION OF GROUND SHAKING CAUSED BY SOFT SOILS

LONG--DURATION ACCELERATION PULSE CAUSED BY FLING OF THE FAULT


Factors that exacerbate earthquake risk2
FACTORS THAT EXACERBATE EARTHQUAKE RISK STATES

BUILDINGS UNABLE TO WITHSTAND LATERAL GROUND SHAKING

LIFELINE SYSTEMS UNABLE TO WITHSTAND PERMANENT DISPLACEMENT ASSOCIATED WITH FAULT RUPTURE, LANDSLIDES, AND LIQUEFACTION


FLOODS STATES

Book of knowledge floods1
BOOK OF KNOWLEDGE: FLOODS STATES

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



Factors that exacerbate flood risk
FACTORS THAT EXACERBATE FLOOD RISK STATES

COMMUNITY’S BUILDINGS AND INFRASTRUCTURE LOCATED IN THE FLOODPLAIN
