Global Warming 101

Video about dating of fossil fuels: Because fossil fuels like coal and oil are so old, they have no radiocarbon left. Nonradioactive carbon is now flooding the atmosphere, which creates a dilution effect. The amount of carbon decreases relative to the amount of normal carbon. It describes how fossil fuel emissions will make radiocarbon dating, used to identify archaeological finds, poached ivory or even human corpses, less reliable. International report confirms was one of three warmest years on record August 2, It’s official: Because radiocarbon has a known rate of decay, scientists can determine about how long it has been since the plant or animal was alive. Radiocarbon dating seizes on that fraction, which decreases over time, to estimate age.

Creation vs. Evolution

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.

Dan July 20, 0 Comments The evidence for evolution is abundant in size and vast in scope, consisting of lines of inquiry from multiple fields converging on this single great insight. With that said, the rich evidence available in the fossil record would be sufficient to prove that the evolution of species has occurred. Although the fossil evidence alone would fill many volumes, I will attempt to summarize and outline the main lines of evidence here. As good as any place to begin, I suppose, is the fossil record.

The Fossil Record — Sometimes when a plant or animal dies its hardened remains can be preserved or fossilized through a variety of physical and chemical processes. These hardened remains reveal the physical history of our ancestors and show clear linkages and intermediaries between past and present groups of species. Intermediaries between all kinds of groups of animals have been found such as between fishes and amphibians, reptiles and mammals, dinosaurs and birds, terrestrial mammals and whales, human and chimpanzee, and so on.

Corn was breed for size and calorie content and barely resembles its ancestor strains. Artificial selection is evident in the domestication of other plants such as wheat, rice, and various fruits and vegetables, and animals such as dogs, cats, sheep, goats and racehorses. Microevolution observed in the laboratory — Microevolution has been observed many times in the lab. A famous example is from the lab of Richard Lenski, an evolutionary biologist working at Michigan State University, that has been running a long term E.

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.

Boyce is a Professor at University of Massachusetts, Amherst. Welcome to The Real News Network. I’m Paul Jay in Baltimore. A new report entitled Cooling the Planet, Clearing the Air: Climate Policy, Carbon Pricing, and Co-Benefits has come to the conclusion that reducing carbon emission isn’t just important because of climate-change issues; it’s also important because of our general health and the effect the process of creating carbon emissions has on the entire environment.

Now joining us to talk about the report is one of the authors, James Boyce. He’s also a professor of economics in Amherst, Massachusetts.

See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric [1] 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.

Berman What Happened in Brief According to abundant geological evidence, an asteroid roughly 10 km 6 miles across hit Earth about 65 million years ago. This impact made a huge explosion and a crater about km roughly miles across. Many asteroids of this type are now known; their orbits pass through the inner solar system and cross Earth’s orbit. Some of these could potentially hit Earth in the future.

Most, but not all are smaller than the one that hit us 65 million years ago. Gaps in the Fossil Record Fossils found in soil layers of different ages show a record of slow, gradual changes in species, with simple organisms gradually being replaced by more complex organisms, apparently by evolutionary processes driven by natural selection. For example, million years abbreviate My ago, the oceans held only simple organisms like algae, while the land was relatively lifeless.

Fish fossils appear in strata after about My ago; dinosaurs and giant reptiles were on the land by My ago. Mammals were not common until after 65 My ago, and humanlike creatures appeared only in the last 4 My. The above description has been challenged for two centuries by religious fundamentalists.

Thus, the layers are successively younger, going from bottom to top. The convention in geology is to number the layers beds within a sequence such that the oldest layer has the lowest number. In the illustration, layer 1 was deposited at time 1. At time 2, layer 2 was deposited on top of layer 1. At time 3, layer 3 was deposited on top of layer 3.

Global average sea level has risen by about 17 cm between and This is a much faster rate than in the previous 3, years. The sea level changes for several reasons, including rising temperatures as fossil fuel burning increases the amount of greenhouse gases in the atmosphere. In a warming climate, the seas are expected to rise at faster rates , increasing the risk of flooding along our coasts. In research published in Nature Climate Change, we show for the first time that the burning of fossil fuels is responsible for the majority of sea level rise since the late 20th century.

As the amount of greenhouse gases we are putting into the atmosphere continues to increase, we need to understand how sea level responds. This knowledge can be used to help predict future sea level changes. CSIRO Measuring sea level Nowadays, we can measure the sea surface height using satellites, so we have an accurate idea of how the sea level is changing , both regionally and in the global mean. Prior to this before , sea level was measured by tide gauges, which are spread unevenly across the world.

As a result, we have a poorer knowledge of how sea level has changed in the past, particularly before when there were fewer gauges. Nevertheless, the tide gauge measurements indicate that global mean sea level has increased by about 17 cm between and What drives sea level rise?

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.

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.

Enzler MSc Characteristics, origin, applications and effects of fossil fuels Humans need energy for just about any type of function they perform. Houses must be heated, energy is required for industry and agriculture and even within our own bodies a constant flow of energy takes place. All processes that provide us with the luxuries of every day live we can no longer live without require energy generation.

This is an industrial process that can be performed using various different sources. These sources can be either renewable or non-renewable. Renewable energy sources are replaced in time and will therefore not run out easily. However, non-renewable energy sources are threatening to run out if our standard of usage becomes too high. Nowadays many renewable energy sources are available for use, for example solar and wind energy and water power.

The 1970s Global Warming Consensus

This belief in long ages for the earth and the existence of life is derived largely from radiometric dating. These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio. 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.

Radiocarbon dating (also referred to as carbon dating or carbon dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.. The method was developed in the late s by Willard Libby, who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon (

Because of the immense time spans to create coal, oil and natural gas, they are classed as non-renewable sources of energy. These are hydrocarbons; primarily coal, fuel oil or natural gas. The age they were formed is called the Carboniferous Period and it was part of the Palaeozoic Era. These raw forms of energy take millions of years to make. By producing electricity from coal, and using oil for transport, we are using up the material that was made more than million years ago before the time of the dinosaurs.

The Carboniferous Period occurred from about to million years ago. At the time, the land was covered with swamps filled with huge trees, ferns and other large leafy plants. The water and seas were filled with algae, the green stuff that forms on a stagnant pool of water. Algae are actually millions of very small plants. As the trees and plants died, they sank to the bottom of the swamps of oceans. They formed layers of a spongy material called peat. Over many hundreds of years, sand and clay and other minerals, which turned into a type of rock called sedimentary, covered the peat.

Layer upon layer piled on top of more rock, weighing heavier and heavier, pressing down on the peat. The peat was squeezed and squeezed until the water came out of it and it eventually, over millions of years, it turned into coal, oil or natural gas.

A religion is a set of beliefs based on the supernatural, which by definition is untestable and impossible to disprove or “unfalsifiable”. All scientific theories have been scrutinized through years of experimentation, and can all be falsifiable. For example, the Theory of Gravity can be proven false if a scientist can devise an experiment where two bodies did not attract each other.

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 .

See some updates to this article. We now consider in more detail one of the problems with potassium-argon dating, namely, the branching ratio problem. Here is some relevant information that was e-mailed to me. There are some very serious objections to using the potassium-argon decay family as a radiometric clock. The geochronologist considers the Ca40 of little practical use in radiometric dating since common calcium is such an abundant element and the radiogenic Ca40 has the same atomic mass as common calcium.

Here the actual observed branching ratio is not used, but rather a small ratio is arbitrarily chosen in an effort to match dates obtained method with U-Th-Pb dates. The branching ratio that is often used is 0.
