Issues for which this is an indicator and why

Atmosphere - Climate variability and change - Weather 

Trends in temperatures and their spatial distribution are an indicator of climate variability and change, which in turn have an impact on our human, economic and environmental health.

Other indicators for this issue:

Land - Contributions and pressures between the land and the atmosphere - Climate 

Trends in temperatures and their spatial distribution are an indicator of climate variability and change, which in turn have an impact on the land.

Other indicators for this issue:

Inland Waters - Catchment scale influences - Influence of climate variability and change 

Trends in temperatures and their spatial distribution are an indicator of climate variability and change, which in turn have an impact on inland waters.

Other indicators for this issue:

Biodiversity - Pressures on biodiversity - Climate variability 

Trends in temperatures and their spatial distribution are an indicator of climate variability and change, which in turn have an impact on biodiversity.
