The climate4you.com website developed by Professor Ole Humlum who is a Danish Professor Emeritus of Physical Geography at the University of Oslo, and Adjunct Professor of Physical Geography at the University Centre in Svalbard.
The website climate4you.com which he edits endeavours to provide an ongoing climate data website which is updated monthly.
Warm (>+0.5oC) and cold (<0.5oC) episodes for the Oceanic Niño Index (ONI), defined as 3 month running mean of ERSSTv4 SST anomalies in the Niño 3.4 region (5oN-5oS, 120o-170oW)]. For historical purposes cold and warm episodes are defined when the threshold is met for a minimum of 5 consecutive over-lapping seasons. Anomalies are centred on 30-yr base periods updated every 5 years. Last 3 month running mean shown: November 2023 - January 2024. Last diagram update: 6 February 2024.
"Climate Change: A Realistic Perspective"
The title of my climate book "Fifteen Shades of Climate" has been changed to "Climate Change: A Realistic Perspective" to better reflect its contents.
Note: I was born in Nelson (New Zealand) and lived in Takaka in 1938-45 when I watched the Takaka River flood, and as a seven-year-old I asked two questions ..Why did it rain, and What were the consequences of the rain. I still have questions.
The new book is identical to the old book, with the exception that a new Author's Foreword has been included.
