Global Observations – The Air
►
10 warmest years in 134-year
record have happened since
1998
► 0.68°C increase over
preindustrial temperatures

Record high temperature events
increasing
►
Increasing numbers of intense
rainfall events
Global Observations – The Sea
►
Sea level +17 cm (6.7”) in past
century
►
Ocean stores ~90% of
additional heat in climate
system
►
►

Top 700 m +0.17°C since 1969
Acidity +30% since beginning
of industrial revolution

Global Observations – The Ice
►
Greenland -285 B tonnes/year
► Antarctica -135 B tonnes/year
►
Glaciers retreating globally

-400 B tonnes/year
►
Arctic sea ice declined rapidly
since 1979
►
Spring snow cover extent has
decreased
►
Snow melting earlier
►
Less of it to melt

Climate Projections – NL in General
►
►
►
Warmer temperatures year round
►
Greater increases in winter and north/west/inland
►
Increased agricultural potential
Less frost events on shoulder seasons
►
More growing degree days
Increased precipitation
►
Average annual accumulation
►
More intense extremes
Sea level rise
►

►
Significant for the island, not so much for the Big Land

Adaptation

Adaptation and Resilience
“Successful adaptation does not mean that negative
impacts will not occur, only that they will be less severe
than would be experienced had no adaptation
occurred.”
-
Natural Resources Canada
“Resilience is the capacity of individuals, communities,
institutions, businesses, and systems within a society to
survive, adapt, and grow no matter what kinds of
chronic stresses and acute shocks they experience.”
-
Adapted from 100 Resilient Cities
Be Prepared!

Adaptation and Resilience
►
Status quo no longer sufficient!
►
►
►
27
Can no longer base designs, regulations, governance, etc on the
historical record
Reduce negative impacts
►
Higher capacity culverts
►
Reinforce/relocate coastal infrastructure
Take advantage of the positive impacts
►
Increase agriculture
►
Plan for lower snow clearing and heating needs
