The conventional K-Ar dating method was applied to the 1986 dacite flow from the new lava dome at Mount St. The whole-rock age was 0.35 /- 0.05 million years (Mya). Excess argon within mineral concentrates from the New Dacite Lava Dome at Mount St. Creation Ex Nihilo Technical Journal 10(3): 335-343. module=research&action=index&page=researchp_sa_r01 Henke, Kevin R.

Ages for component minerals varied from 0.34 /- 0.06 Mya to 2.8 /- 0.6 Mya.

In a 2009 editorial written for Australia’s ABC news, he echoed a sentiment he had argued with similar inelegance in his book by providing the following statement, widely spread nearly word-for-word in climate skeptic circles, without any supporting citation: “Over the past 250 years, humans have added just one part of CO in 10,000 to the atmosphere. The only way to make the first sentence work is with a scientifically useless comparison.

One volcanic cough can do this in a day.” This brief statement — a mere 28 words — yields a remarkably dense buffet of spurious claims and outright falsehoods. All other interpretations fall well short of reality. The question is not about how much other stuff is in the atmosphere.

Rather, the question is about how much stuff humans are adding that wouldn’t already be in the atmosphere, and, as a result, what the the potential for that amount would be to affect climate — a topic for which there is a wide scientific represents only 1/10,000th (0.01%) of the total mass of carbon dioxide in the atmosphere.

These numbers do not check out, even when checked against collected data that ends in the year 2000, according calculations provided by the federally-funded Carbon Dioxide Information Analysis Center: According to Houghton and Hackler, land-use changes from 1850-2000 resulted in a net transfer of 154 Pg C to the atmosphere.

Most scientists today believe that life has existed on the earth for billions of years.

This belief in long ages for the earth and the existence of life is derived largely from radiometric dating.

This age is computed under the assumption that the parent substance (say, uranium) gradually decays to the daughter substance (say, lead), so the higher the ratio of lead to uranium, the older the rock must be.

Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning.

Here I want to concentrate on another source of error, namely, processes that take place within magma chambers.

The best "proof" for millions of years of earth history in most people's minds is radioisotope dating. Steven Austin and others from the Institute for Creation Research on a climb into the crater of Mount St. It was one of those experiences that was well worth every exhausting moment!

Helens provides a rare opportunity for putting radioisotope dating to the test.
