  1. Nitrogen (N2) 78.084% Oxygen (O2) 20.946% Argon (Ar) 0.9340% Carbondioxide (CO2) 0.0383% Neon (Ne) 0.001818% Helium (He) 0.000524% Methane (CH4) 0.0001745% Nitrousoxide (N2O) 0.00003%) Ozone (O3) 0.0 - 0.000007 % Nitrogen dioxide (NO2) 0.000002%) Water vapor (H2O) 1%-4% at surface

  2. 1 Gt = Gigaton = 1 milliard tons

  3. CO2-levetid i atmosfæren Mulig fremtidig CO2-produktion

  4. Forsuring af havet CO2(atmospheric) ⇌ CO2(dissolved) CO2(dissolved) + H2O ⇌ H2CO3 H2CO3 ⇌ H+ + HCO3− (bicarbonateion) HCO3− ⇌ H+ + CO3−− (carbonate ion)

  5. Klimavariation – Jordens baneform, aksehældning og præcession

  6. Klimavariation: Vulkaner, bjergkæder, havspejlsændringer

  7. Havets kolde hjerte

  8. North Atlantic Oscillation (NAO) Index

  9. Danmarks klima år 2100 Kyst: Højere vandstand, flere stormfloder, øget erosion Landbrug: 1-2 mdr. længere vækstperiode, højere udbytte, flere plantesygdomme og skadedyr Skovene: Nåletræer afløses af løvtræ Vild natur: Mange nye arter, udbredelsesgrænse forskydes mod nord Energiforbrug: faldende pga. mindre opvarmning om vinteren, stigende behov for køling http://www.klimatilpasning.dk Varmere sommer, mildere, fugtig vinter, kraftigere nedbør, længere tørkeperioder, kraftigere storme

  10. 1 liter benzin 2,3 kg CO2 1 kg stenkul 2,5 kg CO2 1 kWh el 0,5 kg CO2 1 kWh fjernvarme 0,13 kg CO2

  11. Kyoto (1997): 8% reduktion (1990) i CO2-udslip for EU i 2008-2012 – Danmark forpligter sig 21% reduktion. System af CO2-kvoter København (2009):
