Presentation Transcript

  1. Protecting our Health from Climate Change: a Training Course for Public Health Professionals Chapter 2: Weather, Climate, Climate Variability, and Climate Change

  2. Overview: This Module • Define terms • Discusses climate change and how has it been determined that humans are influencing the climate • Shows some of the climatic changes that have occurred to date • Shows how climate change will affect the weather for decades to centuries

  3. Weather, Climate, Climate Variability, and Climate Change • Definitions • The greenhouse effect • Detection and attribution of climate change • What changes have occurred • What changes are projected

  4. Definitions • Climate is what you expect • Based on 30-year averages • Weather is what we experience day-to-day • Climate variability • Short-term fluctuations around the average weather • Includes ENSO (El Nino-Southern Oscillation) • Climate change • Operates over decades or longer • General circulation models (GCMs) • Scenarios, not predictions
