Glaciation cause

Was Huronian glaciation caused by the amount of carbon dioxide absorbed into plants? --Artman40 (talk) 11:21, 6 April 2009 (UTC)[reply]

Plants were not present at that time, see: Evolutionary history of plants. However photosynthesizing cyanobacteria could have played a role in the onset of the galciation. Wenkbrauwalbatros (talk) 13:53, 9 May 2009 (UTC)[reply]

And it is strange indeed that this short, stubby "article" chooses not to mention the cyanobacteria in its paragraph on the causes of the glaciation.--97.120.35.87 (talk) 22:58, 17 July 2016 (UTC)[reply]

Makganyene

Is there a known derivation for this term? Jim.henderson (talk) 00:31, 21 November 2014 (UTC)[reply]

It refers to a locale in South Africa.--97.120.35.87 (talk) 23:13, 17 July 2016 (UTC)[reply]

How did it end?

The causes are interesting, but so is the other end. I've read that total glaciation could be totally catastrophic and irreversible; what produced the heat to melt the glaciers?--Prosfilaes (talk) 19:06, 5 March 2017 (UTC)[reply]

I agree that the ending should be discussed in the article, provided there's any information to be had. Perhaps something could be taken from Snowball Earth or that article could just be referred to.

In my limited and non-geologist understanding about Snowball Earth periods, volanoes would thaw out the world. Volcanic eruptions on land would melt holes in the ice, spewing CO2 and other greenhouse gasses into the atmosphere. With all the rocks covered up by glaciers, nd no plants on land, there would be nothing for the CO2 to react with. Eventually so much would accumulate in the air that the greenhouse effect would overcome the ice albedo and melt everything. 2601:441:467F:9E00:F907:6112:FCDE:50 (talk) 19:15, 28 March 2020 (UTC)[reply]

Oldest or not?

This article claims this ice age is the oldest one, but then the accompanying chart shows the Pongola glaciation which occurs earlier. 198.91.146.14 (talk) 12:35, 3 July 2018 (UTC)[reply]

It might still be true if the Pongolan is considered to be a local glaciation rather than a global temperature drop. If Vaalbaara was in a polar latitude at the time, it could have been entirely local. 2601:441:467F:9E00:F907:6112:FCDE:50 (talk) 19:03, 28 March 2020 (UTC)[reply]
