One of the problems with the young earth model is that it has to collapse the age of the earth into a fews thousand years.
This results in several problems ... because you can't affect one thing and not affect something else that affects something else ... there is a web of interactions.

Frost Rings in Trees as Records of Major Volcanic Eruptions
quote:
... Wexler's basic premise seems to be supported by Lamb's observation [21] of southward displacement of the sub-polar low-pressure zone in the North Atlantic sector in the first July following a great eruption, and continuing in some cases for 3 - 4 yr. ...
... Synoptic situations more typical of winter may be expected to occur in late spring and in early autumn.
Note as one example 1816 CE ... there was a volcanic eruption in 1814 CE (Mayon) followed by one in 1815 CE (Tambora), each throwing clouds of fine silicate ash into the air causing an ash veil high in the atmosphere. The Dust Veil Index (DVI) was ~3,000 (where the index is scale so that the 1883 eruption of Krakatoa is 1,000) in 1815 CE. The ensuing year (1816 CE) was called the "
year without a summer" because it was so cold, crops failed etc.
The graph also shows how many volcanoes there were in the last 500 years. This graph could be extended into the past with similar frequencies.
Compressing all eruptions into a short couple thousand years would mean at least one a day -- and there would be permanent dust clouds and constant deposition of ash forming a thick blanket over the earth -- think Vesuvius and Pompeii every day ... as well as constant low temperatures and low visibility. Plants couldn't grow, animals couldn't breath.
