Carbon dioxide levels dating far back

Carbon dioxide is a major greenhouse gas and comes from the burning of coal, gas and oil.(AP Photo/Steve Helber) The National Oceanic and Atmospheric Administration said Thursday that carbon dioxide levels averaged 411.25 parts per million in May at the federal Mauna Loa observatory in Hawaii, up from 409.65 a year ago."This technique stands to revolutionize radiocarbon dating," said Marvin Rowe, Ph. "It expands the possibility for analyzing extensive museum collections that have previously been off limits because of their rarity or intrinsic value and the destructive nature of the current method of radiocarbon dating.

Burning coal, gas and oil emits carbon dioxide, which is a major greenhouse gas.Conventional carbon dating estimates the age of an artifact based on its content of carbon-14 (C-14), a naturally occurring, radioactive form of carbon.Comparing the C-14 levels in the object to levels of C-14 expected in the atmosphere for a particular historic period allows scientists to estimate the age of an artifact.Carbon 14 (C-14) dating was considered to be a tremendous breakthrough in science when Willard Libby devised it in 1946. Read, Journal of Near Eastern Studies, Vol, 29, No. Thus, the meaning of dates by C-14 prior to 1600 B. "If the earth and life on earth are really as ancient as the theory of evolution requires, a great proportion of radiocarbon ages should be infinite.But subsequent investigations have revealed it to be wholly inadequate for accurate dating of ancient materials. evolution—a Creation-Evolution Encyclopedia, brought to you by Creation Science Facts. This is because, with a half-life of only 5,730 years, initial radiocarbon in a fossil decreases in about ten half-lives to a level too low to be measured."—Robert E.
