The Holocene Sea Level Highstand
#1
From Watts Up With That?

Guest geological note by David Middleton

Most skeptics are familiar with the Warmunist efforts to erase the Medieval Warm Period and Little Ice Age.

However, many skeptics may not be aware of efforts to erase another paleoclimatological feature: The Holocene Highstand.
What is a highstand?

A highstand is one phase of the sea level cycle (AAPG Wiki)
  • Rising
  • Highstand
  • Falling
  • Lowstand
The highstand is the maximum sea level achieved during the cycle.

The Holocene Epoch

The Holocene Epoch was recently formally subdivided into three stages:

  1. Greenlandian Stage = Lower or Early-Holocene. 11.70 ka to 8.33 ka
  2. Northgrippian Stage = Middle or Mid-Holocene. 8.33 ka to 4.25 ka
  3. Meghalayan Stage = Upper or Late-Holocene. 4.25 ka to present
The abbreviation “ka” refers to thousands of years ago. Lower, Middle and Upper are generally used when referring to rock-time units. Early, Mid and Late are generally used when referring to time units (Haile, 1987). Prior to the formal subdivision, Lower/Early, Middle/Mid and Upper/Late were commonly used; however there was no formal nomenclature. The fake word, “Anthropocene” is not used by real geologists.

There is also an informal climatological subdivision of the Holocene:
  • Preboreal 10 ka–9
  • Boreal 9 ka–8 ka
  • Atlantic 8 ka–5 ka
  • Subboreal 5 ka–2.5 ka
  • Subatlantic 2.5 ka–present
