Dr. R. Watson – Chair of IPCC
speaking to COP 6
“The overwhelming majority of scientific experts,
whilst recognizing that scientific uncertainties
exist, nonetheless believe that human-induced
climate change is inevitable. … the frequency and
magnitude of these type of events: heat waves,
floods, droughts, fires and extreme weather events
leading to significant economic losses and loss of
life, are predicted to increase in a warmer world”

The Delhi (CoP8) Ministerial Declaration
on
Climate Change and Sustainable Development
• …promote sustainable development. …
• (e) Adaptation to the adverse effects of climate
change is of high priority for all countries.
Developing countries are particularly
vulnerable, especially the least developed
countries and small island developing States.
Adaptation requires urgent attention and
action on the part of all countries. …

The Canadian Foundation for
Climate and Atmospheric
Sciences
• Established in 2000
– Budget 2000 awarded one-time $60 million grant
to be disbursed over six years.
• to foster scientific research on:
–
–
–
–
the climate system, climate change,
extreme weather,
air quality and
marine environmental prediction.

Strategies for Adaptation to climate
change must be based on:
-understanding the present relationships and
vulnerabilities
-projecting ahead the changing climate and weather
-working with communities to reduce vulnerabilities
We need to have a:
-strong observational base
-science of climate/weather prediction – university
and governments

CFCAS has committed about two-thirds of its funds
It now has under review proposals for
8 research network and 45 grants
All funds will be expended by 2007.
We need investments for the long-term.
CLIMATE CHANGE STRATEGY
Emissions reduction
strategy
-long-term
-Innovation agenda
Support is needed to
both government
agencies and to
universities to build our
science base.
Adaptation Strategy
– Invest to directly help
Canadians
– Protecting Canadians
from harm and
information to maximize
economic efficiency
– Based on better
predictions of change
from minutes-yearsdecades
To inform and warn Canadians about the future
so they can make better decisions.
