But the impacts of fossil fuels start long before their carbon dioxide reaches the atmosphere. Our new research, published today in Science, looks at the effects of coal, oil and gas extraction on biodiversity. The problem Biodiversity loss is accelerating, and the risks to biodiversity are increasing. We are in the midst of a global biodiversity crisis. The biggest threats to biodiversity are human activities. These act across a range of scales. Even local biodiversity loss can have knock-on large scale impacts on ecosystem function and productivity. Fossil fuel consumption and demand show no signs of levelling off, let alone decreasing. Of course more consumption means more refineries, power stations and infrastructure, in addition to the extraction itself.

And this stasis shows that no gradual process of evolution ever occurred. A thornback ray fossil dating back to the Mesozoic era million years ago has exactly the same characteristics as those living in the sea today. This particular creature, about million years old, clearly demonstrates that the evolutionary process is entirely fictitious. The history of most fossil species includes two features particularly inconsistent with gradualism: Most species exhibit no directional change during their tenure on earth.

See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric  dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days?
Christians , by definition, take the statements of Jesus Christ seriously. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. We will deal with carbon dating first and then with the other dating methods. How the carbon clock works Carbon has unique properties that are essential for life on Earth. One rare form has atoms that are 14 times as heavy as hydrogen atoms:

Global Warming Many people moan throughout the winter season. I know I do. I hate shoveling snow and worrying about whether my pipes will freeze. But I understand that snow and cold temperatures are a part of life. But will they be forever? The news about global warming has dire predictions about the future.

The Radiocarbon Revolution Since its development by Willard Libby in the s, radiocarbon 14C dating has become one of the most essential tools in archaeology. Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials. In contrast to relative dating techniques whereby artifacts were simply designated as “older” or “younger” than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible.
The application of Accelerator Mass Spectrometry AMS for radiocarbon dating in the late s was also a major achievement. Compared to conventional radiocarbon techniques such as Libby’s solid carbon counting, the gas counting method popular in the mid s, or liquid scintillation LS counting, AMS permitted the dating of much smaller sized samples with even greater precision. Regardless of the particular 14C technique used, the value of this tool for archaeology has clearly been appreciated.
However, as with any dating technique there are limits to the kinds of things that can be satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination. Probably the most important factor to consider when using radiocarbon dating is if external factors, whether through artificial contamination, animal disturbance, or human negligence, contributed to any errors in the determinations.
For example, rootlet intrusion, soil type e. Bioturbation by crabs, rodents, and other animals can also cause samples to move between strata leading to age reversals. Shell may succumb to isotopic exchange if it interacts with carbon from percolating ground acids or recrystallization when shell aragonite transforms to calcite and involves the exchange of modern calcite. The surrounding environment can also influence radiocarbon ages. The introduction of “old” or “artificial” carbon into the atmosphere i.
This is a major concern for bone dates where pretreatment procedures must be employed to isolate protein or a specific amino acid such as hydroxyproline known to occur almost exclusively in bone collagen to ensure accurate age assessments of bone specimens.

By , a dead plant could be almost identical to the Dead Sea scrolls, which are more than 2, years old. It describes how fossil fuel emissions will make radiocarbon dating, used to identify archaeological finds, poached ivory or even human corpses, less reliable. As scrolls, plant-based paints or cotton shirts age over thousands of years, the radioactive carbon that naturally appears in organic objects gradually decays.
One of the very foundations of evolution and popular science today is the “geologic column.” This column is made up of layers of sedimentary rock that supposedly formed over millions and even billions of .
History of the greenhouse effect and global warming By S. Enzler MSc History of the greenhouse effect and global warming Svante Arrhenius was a Swedish scientist that was the first to claim in that fossil fuel combustion may eventually result in enhanced global warming. He proposed a relation between atmospheric carbon dioxide concentrations and temperature. He found that the average surface temperature of the earth is about 15oC because of the infrared absorption capacity of water vapor and carbon dioxide.
This is called the natural greenhouse effect. Arrhenius suggested a doubling of the CO2 concentration would lead to a 5oC temperature rise.
Burning fossil fuels is responsible for most sea
The theory—now widely accepted as scientific reality —was mentioned in the news media as early as , and was discussed in scientific circles much earlier than that. The French physicist Joseph Fourier had made the observation in that the composition of the atmosphere is likely to affect the climate. Though the study does not explicitly say that the burning of fossil fuels would cause global warming, there were scientists before him who had made such a forecast.
The earliest such mention that Quartz could find was in the journal Nature in December of
A fossil (from Classical Latin fossilis; literally, “obtained by digging”) is any preserved remains, impression, or trace of any once-living thing from a past geological es include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.
Fossilization There are two major types of fossils – body fossils and trace fossils. Both are the remains of living organisms. Body fossils reveal the body structure of the organism while trace fossils reveal the activities of these organisms. The process of fossilization is called taphonomy. There are three main components. First, there is the death of the organism. Then, there are certain processes that can happen to the organism before it is buried.
These processes can include body decay due to natural elements such as wind, water or attack from predators. Finally, there are certain processes that occur after the organism’s body is buried. These processes result in the different categories of fossils. What are some factors that can affect fossilization? Does the organism have hard or soft body parts? Do the surrounding conditions allow for rapid burial and preservation?
Will the body be exposed to many elements of erosion?

Leave a comment Rational Debate on April 25 said: C14 spiked with atmospheric atomic testing conducted since and has been declining since the atmospheric test ban. This effect is dominating any decline observed in C Jon Neufeld on April 25 said: I don’t know if anyone is ‘denying’ that humankind is increasing the concentration of atmospheric CO2. You have done nothing with regards to the second statement, but congratulations on utterly destroying the strawman in the first.
Bill Yarber on April 25 said: Yes, CO2 concentrations have increased during that period and the industrial revolution and burning of fossil fuels have contributed to some on the increased CO2 in our atmosphere. You did not mention which isotope of Carbon these produce. Since they are organic sources, my guess is they are the same as fossil fuels. Since we’ve only warmed from abnormally low levels about 0.
We didn’t have catastrophic warming then, so we won’t have it now. Ice core analysis from Greenland and Antarctica show that CO2 concentration changes lag temperature changes. Therefore, we would expect CO2 to have risen with or without our contributions since the Earth has warmed from the LIA.

What about the fact that the “simple” organisms are buried in the lower levels and the more “complicated” ones are buried in the higher levels? Doesn’t this fact support the notion that simple organisms evolved into more and more complex organisms over time, with the more complex organisms buried and fossilized above the earlier and simpler life forms? Certainly this seems like a very logical assumption. But, things just aren’t that easy. There are a number of potential problems with this interpretation of the fossil record.
For example, it is interesting to note that some general kinds of fossilized creatures are very generally found in the same relative vertical orientation, with respect to each other in the fossil record, that they would have naturally been found in during life.
At a widely publicized news conference in August of , Dr. Jeffrey Bada of Scripps Institute of Oceanography announced the “discovery” of a new dating method based on the rate of racemization of amino acids in fossil material.
Ronald Vyhmeister Online dating has been a revolution ever since it started, but like every coin has another side to it. Online dating poses some serious side effects, which if not taken care of shall result in disasters. You need to understand on how online dating can affect your life, habits, routine and time management.
Before getting into details, a word of caution to all those passionate online daters: For first timers, it’s an amazing, new and unseen experience which immediately attracts their attention. But you might end up having a bad company, someone who might mislead you, someone who might exploit you and what not? First of all, extensive online dating can turn into an addiction that kills your precious time.
People who tend to get involved in such relationship tend to forget everything else and sit in front of the computer almost throughout the day; such activities not only affect their other work but their health as well. They tend to stay online for long periods, skipping meals and sleep and avoiding their responsibilities.
Print Article For some reason, which I have not yet figured out, at least one person per week has been asking me about the Carbon Radiometric Dating Technique. They want to know if it is accurate or if it works at all. Worse still, sometimes they want to know how evolutionists use Carbon to date dinosaur fossils! The word radiometric as used in this article refers to the supposed use of the decay of radioactive chemical isotopes to supposedly measure the amount of time that has elapsed since an event occurred or a creature lived.
Radiometric Dating Technologies are presented to the public by evolutionists as utterly reliable clocks for dating earth rocks or biological materials. There are more than 80 such technologies that are claimed to work.
In Dr. Raul Esperante teamed up with Dr. Leonard Brand and others to investigate fossil whales within the Pisco Formation of Peru’s Atacama Desert.
Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.
As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.
These are often characterised as the norm, rather than the exception. I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists. Geochronologists do not claim that radiometric dating is foolproof no scientific method is , but it does work reliably for most samples.
It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for “young Earth” theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques. This document is partly based on a prior posting composed in reply to Ted Holden. My thanks to both him and other critics for motivating me.
