- There are two types of humidity: relative, or saturation, and specific, or the amount of water vapour in the air.
- Scientists have found specific humidity has increased, while relative humidity over many regions has declined.
- Changes in humidity have substantial knock-on impacts at both the global and local level, including on the strength and frequency of wildfires.
