How
could it happen that more than a dozen of the most prestigious
scientific associations signed and submitted this letter on ‘climate
change’ without having ensured that the used terminology is
sufficiently defined. Read the rest of the entry

The UNFCCC does not define ‘climate’ at all, while
WMO says: 'climate' is average weather. This website will provide information and ask, does science know what climate is?

FCCC “climate change” | IPCC-2007 “climate change”[5] |
"Climate change" means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods. |
Climate change in IPCC usage refers to any change in climate over time, whether due to natural variability or as a result of human activity. |

[5] See Footnote 1, in: IPCC; Summary for Policymakers, February 2007, with the explanation: This usage differs from that in the Framework Convention on Climate Change, where climate change refers to a change of climate that is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and that is in addition to natural climate variability observed over comparable time periods.

[7] The IPCC was created jointly by two United Nations agencies: the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) in 1988, which - according WMO - has been critical in providing regular assessments of climate science, potential impact of climate change and of policy options, including mitigation and adaptation to climate variability and change.
