Climate Change Summit

2008

slide3

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE

WMO

UNEP

4th Assessment Report

Summary for Policy Makers

“Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.”

“Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.”

What about skepticism and uncertainty?

Scientific skepticism is alive and well, as scientists continue

to analyze data, refine theories, and improve models

Puzzle

Analogy

While several of the pieces are not yet in place, we have

confidence that we know what the overall picture is

slide6

Local Warming: Georgia

  • Sea level rise
  • Heat waves
  • Droughts & floods
  • Hurricanes
  • Air quality
  • Infectious diseases
  • Agriculture
  • Forests
  • Fisheries/wildlife

IMPACTS: economy, ecosystems,

public health & safety, quality of life

slide7

Impacts of drought

  • Mandatory water use restrictions; running out of water
  • Lack of reliable water supply will hurt industry, economic

development, property development

  • Impacts energy generation

(hydropower, power plant cooling)

  • Stress on forests; wildfires
  • Stress on agriculture, livestock
  • Stress on landscape, tourism,

recreation industries

  • Stress on river ecosystems

2007 drought has cost

N. Georgia over $1.3B

ADAPTATION

Policy responses

IPCC, 2001

  • Adaptation is alteration of activities to minimise consequences of climate change
  • Mitigation is reduction of greenhouse gas emissions to prevent dangerous climate change
adapting to an uncertain world georgia s water resource planning
Adapting to an Uncertain World:Georgia’s Water Resource Planning

Goals:

  • Protect public health and environmental quality
  • Meet future water need while protecting aquifers, in-stream uses, downstream users

Strategies:

  • Increase water conservation, efficiency, reuse
  • Maximize water returns to the basin of origin
  • Meet increases for demand through water storage, aquifer management, and reducing demands
  • Protect water quality by reducing pollutants from discharges and runoff from land
slide10

Challenges to regional climate change

  • assessment, mitigation and adaptation
  • Some uncertainty in climate change projections
  • Lack of understanding of how to apply this knowledge to

support decision making and risk analyses

  • Impacts of regional climate change and local vulnerabilities

have been inadequately studied

  • Local/regional mitigation/adaptation strategies are further

complicated by political, cultural, and economic issues

Political will is needed to develop policy and technology options that are practically feasible and cost effective
