  1. Climate Change By Beth Higgins

  2. Overview • What is climate change? • What causes climate change? • Should we be concerned? • Potential impacts • What has been done (legislation) • Do we need all these actions? • Conclusions

  3. Climate Change • The change in climate over a time period which ranges from decades to centuries. • The term refers to both natural and human-induced changes.

  4. Factors affecting Global Climate • Greenhouse gases • Fossil Fuels • Deforestation

  5. Should we be concerned? • Concentration of greenhouse gases in our atmosphere are rising at an alarming rate • Current concentrations of CO2 are 30% above pre-industrial levels • 1/2 of this growth has happened in the past 30 yrs • Climate Trends

  6. Potential Impacts • Longer growing season • More frequent and severe storms • Melting permafrost • Lower lake levels • Heat waves • Changes in rain and snow patterns • Flooding of coastal communities

  7. Framework Convention on Climate Change • Canada signed FCCC in June 1992 • The convention become official on March 21, 1994 • Industrialized nations greenhouse gas emissions at 1990 levels by 2000. • 1995 parties began to set targets for the post 2000 era.

  8. FCCC continued • 3rd meeting, Kyoto, Japan, December 1-10, 1997 • parties agreed for industrialized countries to cut greenhouse gas emissions by 5.2% by 2010

  9. Actions in Canada • National Action Program on Climate Change (NAPCC) • Federal Action Program on Climate Change • Voluntary Challenge • 20% Club of Canadian Municipalities

  10. 1998 Budget • Develop a national implementation strategy • Carry out public education and encourage early action by Canadians • Assess best practices and mechanisms (emissions trading) to reduce impact of CC • Begin quick-start pilot projects • Engage developing Countries in CC work

  11. Do we need All these Actions? • If models are correct, we need effective response and early action • If concerns are premature or overstated, time and opportunities to adjust • Benefits: • reduce pollution • better urban air quality • more efficient economy • new jobs (new technology)

  12. Conclusions • Canada has a number of programs in place to reduce emissions • No numbers have been released to see where we stand • Are we going to make it?

  13. The End
