- This page distinguishes weather from climate, defining weather as short-term atmospheric conditions and climate as long-term patterns. It covers chaos theory's impact on weather predictions, misconceptions about weather forecasts and climate change, introduces climate and radiative forcing concepts, and discusses how anthropogenic greenhouse gases affect climate systems.
- 1.2: The Past
- This page explores the concept of "Deep Time" through the geology and ecology of California's White Mountains, focusing on the Reed Dolomite and the Bristlecone pine as critical indicators of past climates via dendrochronology. It presents studies revealing 600 years of climate history, including extreme droughts and historical climate variability, emphasizing lessons for current trends and future resilience strategies.
- 1.3: The Present
- This page discusses California's Mediterranean climate, highlighting its warm, dry summers and temperate, wetter winters, alongside notable geographical variations leading to extremes like aridity in Death Valley. It addresses climate change's impact, including rising temperatures, droughts, and wildfires, threatening water resources and ecosystems. The text emphasizes challenges from significant drought periods, the importance of snowpack for water supply, and the effects of atmospheric rivers.
- 1.4: The Future
- This page examines California's environmental forecasts, emphasizing the threats posed by climate change such as rising sea levels and increased heat. It discusses "King Tides," warning of future sea level rises of up to 0.3 meters by 2050, which would impact infrastructure and ecosystems. Citing the IPCC, it attributes these changes to thermal expansion and land-based ice melt.
- 1.5: Hotter, Drier, Tougher
- This page highlights the dangers climate change presents to California, detailing its geological vulnerabilities and potential devastation of infrastructure and ecosystems. It notes that while California has begun to take climate action, such as emissions regulations, these measures alone are inadequate without wider collaboration.
