Climate Change
A quote from Depleted Cranium, quoting the economist, quoting someone else answering a question about a graph someone posted:
Other common changes at Australian sites over time include location moves, construction of buildings or growth of vegetation around the observation site and, more recently, the introduction of Automatic Weather Stations.
The impacts of these changes on the data are often comparable in size to real climate variations, so they need to be removed before long-term trends are investigated.
If things like the difference between shade and a few feet and altitude are comparable to "real climate variations," how serious could these real climate variations really be?
