2. BEACONS, registered charity number 700161, is one of a network of development education centres (DECs) covering the whole country. DECs are government authorised but receive no direct government funding. Run entirely by volunteers, BEACONS is the DEC for Herefordshire and Worcestershire. Our aim is to promote knowledge and understanding about the wider world in the two counties and beyond. We do this in a variety of ways, including providing learning resources, staff professional development, speakers, public lectures and by running conferences. Our website http://beaconsdec.org.uk/ contains more information about our activities and plans and is a valuable free source of information for teachers, students and the public generally, including our three continuously updated and free Guides to Climate Change.http://beaconsdec.org.uk/ Working to promote awareness and understanding of issues and developments in the wider world

7. The Man who started it!

8. James Watt The man who started it! 1769

9. The Early Days An increased demand for Energy and a rapid rise in Greenhouse Gas Emissions

10. 1824 Jean-Baptiste Joseph Fourier 1889 Svante Arrhenius Arrhenius' Greenhouse Law is still used today

16. Effects of Climate Change Good or Bad? Harmful (for all)? More Extreme Weather – More Frequently Rising sea levels Ocean Acidification Desertification Beneficial (for some)? CO 2 promotes plant growth Farming possible in areas previously too cold, e.g. Greenland, Siberia Reduction in Arctic summer sea ice allows shipping to use the NE and NW passages, and allows extraction of oil and other minerals

17. What do we know – How certain are we of each of the following? 1.CO 2 is a greenhouse gas. The amount in the atmosphere has increased steadily from about 280ppm in pre-industrial times to about 400ppm today 2.CO 2 emitted by burning fossil fuels remains in the atmosphere for at least 100 years 3.Other GHGs, notably water vapour and methane, have a stronger effects but remain for much shorter periods 4.Global temperatures have risen by about 0.8 0 C in the last 100 years but since 1998 have risen only slightly 5.Sea levels have been rising for at least the last 150 years at a fairly steady 3.2 mm a year 6.The rise in temperatures and sea levels is largely a result of burning fossil fuels 7.If atmospheric CO 2 reaches 450ppm global temperatures are likely to exceed 2 0 C above those of 1900, and this will probably cause catastrophic climate change 8.The amount of CO 2 emitted by each country

18. Climate Change What should we do?

19. A Global Problem AN INTERNATIONAL TREATY TO REDUCE CO 2 EMISSIONS: WHAT’S THE PROBLEM?

20. Global Action The Paris Aims: Reduce CO 2 emissions so as to keep Global temperature increase below the 2°C limit from Pre- Industrial times. Keep Carbon levels in the atmosphere below 450ppm Avoid the worst of Climate Change Brief History of Key UNFCCC Annual COPS: Rio Earth Summit, 1992 COPS COP3 Kyoto, 1997 COP15 Copenhagen, 2009 COP21 Paris, 2015 (30 th Nov-12 th Dec) The United Nations and Climate Change

21. Possible Measures Energy Efficiencies Use energy / resources more efficiently Rethink Personal Lifestyles Sustainable Transport Industrial Processes Agriculture Design of Things Consumption Houses – heating and cooling Low Carbon Technologies Renewables / Carbon-free energy: Wind, Wave, Tidal, Solar, Hydroelectric, Geothermal Nuclear Fission Other Available Options? Natural Gas – Fracking Biomass Fuels Nuclear Fusion Carbon Capture and Storage Increase Natural CO 2 Absorption Geo-engineering Prepare for a Hotter Planet Do Nothing – Wait and See Mitigation and Adaptation

22. What should we do? 1.Mitigate – Actions to prevent worsening of Climate Change 2.Adapt – Actions for living with Climate Change Impacts 3.Reduce Greenhouse Gas Emissions 4.More Efficient use of Energy and Resources, with Less Waste 5.Prepare for a Hotter Planet 6.Geo-Engineering Techniques 7.Nothing – Wait and See 8.Think Global – Act Local

23. If all else fails, what future for humanity?

24. Move to another planet…?
