During an average human lifetime, Climates do not appear to change. However, they are in a constant state of change
Long Term Climatic Changes Ice Ages Interglacial Intervals
Ice Ages - period of extensive glacial coverage. There have been several glacial advances and retreats
Interglacial Intervals - Warm periods between glaciation
Short Term Climatic Changes Seasons El Nino
Seasons - regular variations in daylight, temperature, and weather patterns
El Nino - Weakening of the equatorial current brings warmer waters to the west coast of South America
Evidences of Climatic Change
- Tree Rings - Ice Core Samples - Fossils - Radio Carbon Samples
Causes for Change
Human Activity - Pollution may aid global warming
Volcanic Activity - Dust blocks solar radiation lowering global temperatures
Solar Activity - increased solar activity causes increased global temps. 11yr cycle
Earth’s Orbit - More circular orbit = cooler global temps. 100,000 yr cycle
Earth’s Wobble - Reversal of Earth’s Tilt reverses seasons. 26,000 yr cycle
Is there a difference?. Climate Vs. Weather Climate Long-term weather patterns of an area Weather Current state of the troposphere Short term variations.
Ch Climate Climatology – the study of Earth’s climate and the factors that affect past, present, and future climatic changes. Climate is the long-term.
Heat Budget and Climate Change. Heat Budget is the result of a balance between energy received (insolation and Earth’s Interior) and energy lost (terrestrial.
14.3 Climatic Changes.
Climatology Climatology is the study of Earth’s climate and the factors that affect past, present, and future climatic changes. Climate describes the long-term.
Learning Log We have been talking about weather, but we also hear people talking about climate change. In a complete sentence describe what you think the.
