Despite preaching about the importance of long records, hydrologists are in fact more comfortable with short ones.” Klemeš, 1989. The improbably probabilities of extreme floods and droughts.

Traditional planning would consider flow characteristics of the raw water streams as “knowns” in the system. [ … that is, a stationary climate and water regime]

“We find a significant increasing trend in the length of the growing season and in the associated available heat. The winter temperature is less damaging and the frost-free periods are longer.”

“Stationarity— the idea that natural systems fluctuate within an unchanging envelope of variability — is a foundational concept that permeates training and practice in water-resource engineering.”

the use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to
the adverse effects of climate change

This large belt of country embraces districts, some of which are valuable for the purposes of the agriculturalist, while others will forever be comparatively useless. … John Palliser, London, July 8, 1860

“The main way climate change is perceived is through changes in extremes because those are outside the bounds of previous weather. …

Despite preaching about the importance of long records, hydrologists are in fact more comfortable with short
ones.”

Natural climate variability poses inherent limits to climate predictability … contributes substantial uncertainty to temperature and precipitation trends over North America, especially in winter at mid and high latitudes… [It] is unlikely to be reduced as models improve
