  5. 5. “The last time there was this much carbon dioxide (CO2) in the Earth's atmosphere, modern humans didn't exist. Megatoothed sharks (Megalodon - 2.6-23 million years ago) prowled the oceans, the world's seas were up to 100 feet higher than they are today, and the global average surface temperature was up to 11°F warmer than it is now.” Michael Mann, climate scientist, Pennsylvania State University (2013)

  11. 11. Resultant smog 11
  12. 12. • The greatest effect will be on the atmospheric concentration of water vapour, which will lead to decreases in ozone in the background troposphere but increases in more polluted regions where there are higher nitrogen oxides concentrations. • Hot summers like 2003, when there was a substantial photochemical smog episode in Europe, including SE England, are likely to become ‘typical’ by the 2040s, leading to a higher frequency of summer pollution episodes. • Episodes of winter smog, by contrast, are likely to be less prevalent because of a likely decrease in the frequency of winter stagnation events, where low wind speeds and atmospheric stability hinder the dispersal of pollutants.

  17. 17. Why Mining? 17
  18. 18. • The truth about AQ-influenced deaths brought forward, life years lost Key AQ profile-raising areas 18
  19. 19. • Serious, sustained cuts in carbon emissions • Peak Oil and FF Phase-out • Dealing practically with climate change: – Adaptation – Building resilient developments & cities • Decarbonising transport, domestic and commercial sectors • Meeting EU Limit Values Key Future Stewardships 19
  20. 20. • Your clients are never Wrong, you just need to bring all your skills to bear to move them firmly into the Right space. • Your clients will have an idea of what they Want, it is your job to show them what they, in fact, Need. • Ask more questions. You seek knowledge, and all around are those willing to dispense it. • You’re not as bad at air quality modelling as you imagine. • Actually, you probably are….. • Don’t worry about the future; or do worry, but know this - that worrying is as effective as trying to understand Government air quality policies. • Do one thing everyday that scares you: I am available for tutorials, that usually does the trick. • Be nice to your peers; they are the best link to your past and the people you will be working with during your career. ….and finally 20
  21. 21. • Learn and become knowledgeable about subjects other than air quality. • That way, you won’t end up talking to the wall at parties… The End 21
