# Weather vs. climate (and climate change vs. global warming)

## Short answer
Weather is the short-term state of the atmosphere: today's rain or sun. Climate is the long-term average of weather in a place. A short version: climate is what you expect, weather is what you get. [S2]

## Related terms
- **Global warming** is the long-term warming of the planet. [S1]
- **Climate change** includes global warming but is broader: rising seas, shrinking glaciers, faster ice melt, and shifts in when plants flower. [S1]
- So "global warming" is one part of climate change, not a synonym. [S1]

## Why the difference matters
One cold week does not disprove a warming climate, because climate change is about changes in long-term averages, not single days. [S2]

## Claims
- id: C1
  claim: Weather is short-term conditions; climate is the average weather over a long period.
  source: S2
  evidence: "Weather reflects short-term conditions of the atmosphere while climate is the average daily weather"
- id: C2
  claim: Climate is what you expect, weather is what you get.
  source: S2
  evidence: "Climate is what you expect, weather is what you get."
- id: C3
  claim: Global warming is only one aspect of climate change.
  source: S1
  evidence: "global warming" is only one aspect of climate change"
- id: C4
  claim: Global warming refers to the long-term warming of the planet.
  source: S1
  evidence: "refers to the long-term warming of the planet"
