How do scientists use carbon dating
“When someone points to this and says this is the warmest temperature on record. If you can adjust temperatures to 2/10ths of a degree, it means it wasn’t certain to 2/10ths of a degree,” he said.
() “The UN IPCC wisely avoided making the claim that 51% of a small change in temperature constitutes a problem.
Lindzen cautioned: “The most important thing to keep in mind is – when you ask ‘is it warming, is it cooling’, etc. “I urge you when looking at a graph, check the scales! And they are arguing over hundredths of a degree when it is uncertain in tenths of a degree,” Lindzen said.
— is that we are talking about something tiny (temperature changes) and that is the crucial point.” Lindzen also challenged the oft-repeated UN IPCC claim that most of warming over past 50 years was due to mankind. The uncertainty here is tenths of a degree,” he noted. “And the proof that the uncertainty is tenths of a degree are the adjustments that are being made.
The only consistent way to interpret the geological record in light of this event is to understand that fossil-bearing rocks are the result of a massive global Flood that occurred only a few thousand years ago and lasted but a year.
Atoms may stick together in well-defined molecules or they could be packed together in large arrays.This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay.The first lesson, Isotopes of Pennies, deals with isotopes and atomic mass.By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.
