Chapter 1: Climate vs. Weather
What Is Climate? โ๏ธ
Climate is the longโterm pattern of temperature, rain, and wind in a region.
- Weather: changes hour to hour, day to day
- Climate: averages over 30+ years
Examples:
- A desert climate: hot, dry most years
- A polar climate: very cold, icy
Understanding climate helps us see when longโterm patterns start changing.
What Is Climate Change?
Climate change means longโterm shifts in Earthโs average climate.
Key signs:
- Rising global temperatures ๐ก๏ธ
- Changing rainfall patterns
- Melting ice and snow
- Rising sea levels
Small yearly changes are normal. Climate change is when trends keep moving in one direction for decades.
Natural vs Human Causes
Climate can change naturally:
- Volcanoes
- Changes in Earthโs orbit
- Solar activity
Todayโs rapid warming is mainly from human activities:
- Burning coal, oil, gas
- Deforestation
Natural changes are usually slow. Current warming is much faster, which is why scientists are concerned.
Evidence the Climate Is Warming
Scientists use many clues:
- Thermometers: surface air and ocean are warmer
- Ice cores: show past COโ and temperature
- Glaciers: shrinking almost everywhere
- Oceans: rising and becoming warmer
- Seasons: spring comes earlier in many places
Different types of evidence all point the same way.
