  1. Climate Change RECCC Pédzi V.J. Girigori MSc Curaçao, June 8th -9th , 2011

  2. Overview • What is Global Warming • Observations (last 100 years) • Climate Variability • Expected Impacts

  3. Observations

  4. Observations Change in: -Temperature -Sea level -Snow coverage

  5. Curaçao Observations

  6. Global Warming

  7. Global Warming • Greenhouse effect first discovered by Joseph Fourier in 1824, • Is the process in which the absorption of infrared radiation by an atmosphere warms a planet. • Without these greenhouse gases, the Earth's surface would be up to 30 °C cooler.

  8. % : 1 part per hundred, ppm: 1 par per million Global Warming: Type of Gasses 200 years 280-380 ppm

  9. Global Warming: Radiative Forcing

  10. Global Warming

  11. Global Warming: Source of GW

  12. Climate Variability

  13. Climate Variability • The mean indicates the expected value of a random variable • the variance is used as a measure of how far a set of numbers are spread out around the mean A Dataset can be characterized by a mean and a variance Why is the change in climate variability important??

  14. Climate Variability: Temperature Maximum (TNx) and minimum (TNn) of daily minimum Temperature Maximum (TXx) and minimum (TXn) of daily maximum Temperature

  15. Climate Variability: Temperature The diurnal temperature range is the difference between the maximum and minimum temperature Change in periods of consecutive lower temperatures (CSD) and periods of consecutive warmer temperatures (WSD)

  16. Climate Variability: Precipitation Consecutive wet (CWD) and dry days (CDD) show the change in the rainy and dry periods Changes in total precipitation Changes in extreme precipitation

  17. Expected Impacts

  18. Expected Impacts: Temperatures

  19. Expected Impact: Sea Level Rise

  20. Temperature Variability An extremely likely (>95%) increase in temperature, warm spells and heat waves An extremely likely (>95%) increase in warmer and more frequent hot days and nights Increase in evaporation due to higher temperatures Precipitation Variability A more likely than not (>50%) increase of extreme rainfall events A more likely than not (>50%) increase of the dry season A very likely (>90%) increase in rainfall intensity Expected Impacts: Curaçao
