From time to time we talk about evidence that is a problem for those who insist that the Earth is only 6,000 years old. For example, see Can Noah’s Flood Explain Banded Iron Stripes? Wikipedia has articles on other evidence, such as Dendrochronology (tree ring dating), which can demonstrate a chronology going back over 11,000 years, and Ice core chronology can go back hundreds of thousands of years. The TalkOrigins Index to Creationist Claims has more information, such as ocean sediments.
We have some more trouble for creationists today from Physorg: Study of stalagmites in caves in China reveals 640,000 years of Asian monsoon history. Here are some excerpts, with bold font added by us:
A team of researchers with members from China, the U.S., Austria and Singapore has used their analysis of stalagmites in a cave deep in central China to map over 640,000 years of monsoons in Asia. In their paper published in the journalNature, the team describes their analysis of the cave formations, what they found and how they were able to use what they learned to better understand other world events over the same time period.
This is the paper in Nature: Earth science: An extended yardstick for climate variability, but you need a subscription to read it. We’ll stay with PhysOrg. They say:
The annual monsoon season in Asia is a major event, bringing rains that are used to grow crops for an enormous number of people. Because of its importance, scientists would like to know more about it, such as what might happen as the planet heats up. To learn more, the researchers looked for a way to look back at what has happened in the past, and to do that, they ventured to the mountains in central China and descended into Sanbao Cave — there stalagmites have been growing up from the cave floor for hundreds of thousands of years, carrying with them, a history of the factors that led to their growth.
What can the creationists do to wiggle out of that? They’ll probably ignore it. Let’s read on:
The stalagmites grow at different rates depending on how much rain falls and leaks through the mountain above and down into the cave — during heavy rains, such as occur during monsoon seasons, layers of calcium carbonate build up, holding information about the air and rainwater at a particular point in time, which scientists can analyze to gain a good measurement of climate conditions. They can also look for dissolved uranium, which can be used to date the layers of stalagmite buildup. Together, the two sources of information can be used to create a climate timetable for past monsoon seasons, going back as far as 640,000 years — the most detailed and accurate monsoon record to date.
Two different lines of evidence, both pointing to the same result. Can creationists claim that the Flood was responsible? Sure they can. They’re good at reality denial.
There’s more in the PhysOrg article, but we’ve copied enough. Now we’ll wait for the creationist reaction — if there is any.
