You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 44.222.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 10:53, 20 August 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''Preboreal''' is an informal stage of the Holocene epoch. It is preceded by the [[Late Pleistocene|Tarantian]] and succeeded by the [[Boreal (age)|Boreal]]. It lasted from 10,300 to 9,000((nbsp))[[Before present|BP]] in radiocarbon years or 8350((nbsp))BC to 7050((nbsp))BC in Gregorian calendar years ([[8th millennium BC]]). It is the first stage of the [[Holocene]] epoch. The [[preboreal oscillation]] was a short (ca. 150 years) cooling episode within the preboreal. 

The Preboreal was an informal subdivision of the Holocene, and as stratigraphy and dating techniques have improved since this 1972 proposal the dates would be different if proposed today. Instead others have begun to use the terms Early, Middle and Late, which would be Lower, Middle and Upper in respect of Holocene sediments. If this terminology were to be used the preboreal would be replaced by Lower Holocene which would be dated 11.7 – 8.2 ka B2K.<ref>((Cite web |url=http://www.ub.edu/ice/sites/default/files/docs/jornades/Walker2012.pdf |title=Formal subdivision of the Holocene Series/Epoch: a Discussion Paper by a Working Group of INTIMATE (Integration of ice-core, marine and terrestrial records) and the Subcommission on Quaternary Stratigraphy (International Commission on Stratigraphy) |access-date=2016-05-26 |archive-url=https://web.archive.org/web/20170810072516/http://www.ub.edu/ice/sites/default/files/docs/jornades/Walker2012.pdf |archive-date=2017-08-10 |url-status=dead ))</ref>

In July 2018 the [[International Commission on Stratigraphy]] (a part of the IUGS) ratified [[Greenlandian]] as the globally recognised first age of the [[Holocene]], much overlapping with the North European regional term Preboreal.<ref name=ics>((cite web |last1=International Commission on Stratigraphy |title=ICS chart containing the Quaternary and Cambrian GSSPs and new stages (v 2018/07) is now released! |url=http://www.stratigraphy.org/index.php/ics-news-and-meetings/120-ics-chart-containing-the-quaternary-gssps-and-new-stages-v-2018-07-is-now-released |access-date=15 July 2018))</ref>
