The document discusses climate resilience and infrastructure challenges posed by climate change. It notes increasing natural disasters are causing billions in damages annually. The need for resilient infrastructure to withstand gradual climate changes and periodic shocks is discussed. Challenges include uncertainty around projections, high adaptation costs, difficulty coordinating stakeholders, and economic risks to business from disruptions. Solutions proposed include standards, certification programs, insurance products, international city networks, and innovative infrastructure technologies and monitoring tools to enhance resilience.

Access to funding and implementing adaptation measures is
often costly
Informing stakeholders about climate change and the various
levels of acceptable risk can inhibit the formation of a
common strategy and ability to take responsibility for the
phenomenon
Increasing stakeholders makes it harder to take decisions and
implement regional adaptation strategies

Some regions are affected more
rapidly than others, such as the ice
caps. Polar regions warm twice as fast
as the rest of the planet, according to
ADEME.
According to the IPCC, temperature change, notably planetary
warming, is caused primarily by an increase in greenhouse gas,
which traps infrared light. In this way, heat is retained and the
Earth’s land and ocean surface heats in a heterogenous manner.

on the CMIP5 model.
RAINFALL PATTERNS
The IPCC explains changing rainfall patterns by the variation in
atmospheric moisture (warming oceans, melting glaciers, etc.)
via the action of greenhouse gases within the troposphere and
aerosols on the structure of cloud formations.

© Climate Change 2013: The Physical Science Basis / IPCC – figure 11.15 - 2013
According to ADEME, the circulation of air masses
disturbed by global warming, will modify the wind
patterns. The intensity and direction of prevailing
winds are susceptible to change.

106. MELTING PERMAFROST
The IPCC defines permafrost as permanently frozen soil, present
when temperatures remain below 0°C for several years.
However, as atmospheric temperatures rise, permafrost
disappears.
Projected change, in square kilometers, of
permafrost in the Northern Hemisphere by
2100 based on 1986-2005 and according
to different RCP scenarios. The projection is
based on the CMIP5 multi-model. Thick
lines correspond to the multi-model
average. Thin lines indicate inter-model
spread (standard deviation). The black line is
calculated based on the average of
reanalysis of ECMWF, ERA, JRA, MERRA and
CFSRR. The current estimated level of
permafrost is around 12 and 17 million km2
(Zhang et al., 2000). © Climate Change 2013: The Physical Science Basis / IPCC – figure 12.33 - 2013

Projected percentage change in the
maximum annual accumulation of
precipitation over five days by
2081-2100 based on 1981-2000
and according to the RCP 8.5
scenario. The 2010 floods in Pakistan killed
1,760 and left 10 million homeless
according to the UN. Damages are
estimated $9.5B according to EM-
DAT.
The French government defines flooding as a temporary
submersion in water of land that is not ordinarily inundated,
regardless of cause. According to the IPCC, that can lead to
flooded rivers, urban runoff, coastal flooding by seawater
inundation or glacial lake outburst flood.

109. TROPICAL CYCLONES
The IPCC defines tropical cyclones as a powerful cyclonic
depression forming above tropical waters. They are
distinguished from weaker systems (often called depressions or
tropical disturbances) by exceeding a wind speed threshold. In
this way, a tropical storm when surface winds reach an average
speed of 18-32 m s-1 per minute. Beyond 32 m s-1, the
tropical cyclone is called a hurricane or typhoon, depending on
the region where it originates.
Hurricane Isabel caused $3.6B in
damages and killed 47 people in 2003
in the Caribbean and eastern seaboard
of the US and Canada, according to
NOAA and NCDC.
©ClimateChange2013:ThePhysicalScienceBasis/IPCC–figure14.17-2013

110. STORMS
The French government defines storms as atmospheric
disturbances (or depressions) that form when two air masses
with distinct characteristics (temperature, humidity) meet and
cause potentially strong winds. Unlike tropical cyclones, they
may continue to grow in strength while moving across land.
Heavy rain, snow and thunderstorms may accompany the strong
winds.

storm Xynthia in 2010 killed 47 in

111. CLIMATE CHANGE, TROPICAL CYCLONES
AND STORMS
Projected percentage change in the
occurrence and intensity of tropical
cyclones by cyclone basin by 2081-2100
based on 2000-2019 according to a
scenario similar to A1B.
Four parameters were taken into
account: percentage variation of (I) the
total annual frequency of tropical storms,
(II) the annual frequency of category 4
and 5 storms, (III) the average lifetime
maximum intensity (LMI) and (IV) the
precipitation rate under 200 km from the
eye of the storm at the time of the LMI.
For each measurement, the solid blue
line is the best estimate of the expected
percentage change and the colored bar
indicates confidence interval of 67%
(probable) for this value. If no metric is
shown, sufficient data is not available to
perform an assessment.© Climate Change 2013: The Physical Science Basis / IPCC – figure 14.17 - 2013

112. DROUGHT

Projected change in the annual number of consecutive
dry days (with daily precipitation under 1mm) by 2081-
2100 based on 1981-2000 and according to the RCP 8.5
scenario. The projection is based on the CMIP5 model.
The IPCC defines drought as a phenomenon that occurs when
precipitation falls well below the normal recorded rates, causing
a serious water imbalance with potentially devastating affects
on resource production.

113. 112
FOREST FIRES
Dry conditions increase the likelihood of forest fires,
which, together with human activities, can compromise
the forest’s resilience to climate change.
© State Farm – 2007 – CC-BY-2.0
According to the French government, forest
fires occur primarily during drought periods
when plants have a low water content. They
may have natural causes (lightning, volcanic
eruption) or human causes (criminal or
accidental).
San Diego threatened by California’s
forest fires in October 2007. 8 people
died and material damages reached
$2.8B according to EM-DAT.
In December 2017, California was once
again ravaged by 29 forest fires causing

The IPCC defines extreme temperature waves (heat wave and
cold snaps) as periods of harsh and abnormally hot or cold
atmospheric conditions over a given period. In France, heat
waves correspond to at least 3 consecutive days and nights of
intense heat and cold snaps to at least 2 consecutive days of
intense cold.

115. Rising moisture and precipitation in certain regions,
combined with unfavorable land development, may
increase the number of landslides linked to water.
LANDSLIDES
On December 15, 1999, heavy rains caused a
landslide in the state of Vargas in Venezuela,
causing at least 30,000 deaths and $1.8B in
damages according to USGS.
The IPCC defines a landslide as a mass of
material that has moved downhill by gravity,
often assisted by water when the material is
saturated; rapid movement of soil, rock or
debris down a slope.

116. THE QUALITIES OF A
RESILIENT SYSTEM

117. A REFLECTIVE SYSTEM
According to 100RC, reflective people and institutions use
past experiences to inform future decisions and modify
norms and behaviors in turn.
Example:
A reflective planning process is more apt to respond to new circumstances
Source : 100RC

118. A ROBUST SYSTEM
According to 100RC, a robust project is well designed, built
and managed. It includes measures to ensure that failures are
predictable, safe and not disproportionate to their cause.
Example:
Robust protection infrastructure will not break down in a catastrophic way
when the design thresholds are exceeded

119. A FLEXIBLE SYSTEM
According to 100RC, flexibility refers to the drive and capacity
to adopt alternative strategies in response to changing
circumstances or sudden crises. Systems can be made more
flexible by introducing new technologies or knowledge,
notably by recognizing traditional practices.
Example:
In a period of crisis, cities can reassign city buses for emergency
evacuations.

120. AN INTEGRATED SYSTEM
According to 100RC, integrated processes combine systems
and institutions and can also trigger additional benefits as
long as resources are shared and stakeholders can work
together to achieve greater goals.
Example:
Integrated urban planning enables a city to cope with multidisciplinary
problems, such as an emergency response to catastrophe through
coordination
Source : 100RC

121. A RESOURCEFUL SYSTEM
According to 100RC, resourceful people and institutions can
recognize other ways to use resources during crises to meet
their needs or achieve their goals
Example:
Although households in the cities of Chile’s central valley use water provided
by municipal networks, service is frequently out after strong earthquakes. In
response, many households have wells to maintain their water supply.

122. A REDUNDANT SYSTEM
According to 100RC, redundancy refers to the reserves
available for coping with disturbances caused by extreme
stress, demand spikes or external events. This includes a
diversity of ways to meet a given need.
Example:
Redundant energy systems deliver several solutions for supplying networks
during demand spikes or service outages
Source : 100RC

123. AN INCLUSIVE SYSTEM
According to 100RC, inclusive processes focus on expanded
cooperation aiming to create a shared vision and a feeling of
shared ownership in order to build resilient cities
Example:
Advance warnings enable at-risk populations to protect themselves and
minimize human and material damages

124. FOCUS ON FUNCTIONAL RESILIENCE:
THE BUSINESS CONTINUITY PLAN
To be resilient in response to a natural
catastrophe, a business or institution will
need to implement a business continuity
plan (BCP) to maintain a minimum level of
service without its usual human and material
resources.
This includes a strategic document updated
regularly to plan the reaction to adopt in
response to a hazard in order to minimize the
impact on business.
In practice:
• In response to a climate shock like a
tropical cyclone, this may include taking
cover to protect staff, equipment and
installations, while working to restore
priority activities within a short time frame
• In response to a prolonged episode, it may
involve a backup for the portion of the
company that can be backed up
