The Earth Probably Go to A New Era Millions of Years Sooner

According to National Geographic website, the older one grows, the quicker time passes. Bridget Marquardt Have a Glance at leather bags The earth who is 4.57 billion years old may have the same feeling. Some scientists point out that the earth has entered into a new era, which is millions of years earlier than the time it should start its new era. Generally speaking, the geological time will last 3 million or longer of the earth according to the rock mass. And now we have just entered into a new era, 11.5 thousand approximately.Rihanna’s leather bags , Take a Look and Make a Comment

Recently, a new published paper points out that we have entered a new geological age-Anthropocene. The Nobel Prize winner Paul Crutzen created the word in 2002 which is used to reflect the unprecedented change in human history in about two hundred years since the Industrial Revolution. Now human beings have a big effect on earth, such as the destruction of habitat, the pollution for environment and the extinction of animals and plants and these lead to the formation of the distinct boundary of the rock layer of earth. We are good at energy utilization and environment control. Now, we are the main driving force for geological process on the surface of our earth. Even so, the world's largest geological authority the International Union of Geological Sciences might take several years or even decades to formally confirm the new era.What is Bad for the Tinge of women handbags ?

Scientists firstly must make sure and define a border line or a mark, normally locating in the mid of terrane, to get approvals on Anthropocene this concept. A paleontologists and meteorologist from University of Leeds in Britain said, [ The keys lies in how geologist will identify the marks of the begining of Anthropocene in mineral deposits in the following thousands or millions of years." But nothing can be as simple as one has imaged, because the sign should be very precise, people have to sign it out in different regions around the world. One of the candidate marks for the signs is a unique radioactive mark left by atomic test. Such research has been done ever since 1945.How Dramatic!! Journalists all Have a Crush on womens wallets

Scientists discovered through researches that the earth entered the Tertiary about 65.5 million years, which was the period when large-size dinosaurs was extincted. The studies showed that there was a big difference between the carbon isotopes which was contained in the marine plankton and the carbon isotopes which was contained in the marine plankton before the human starting to burn the fossil fuels in a large scale. Scientists firstly must make sure and define a border line or a mark, normally locating in the mid of terrane, to get approvals on Anthropocene this concept. It is not merely driven by scientists` curiosity for urgent call to declare a formal entrance of Anthropocene era.

Scientist wrote on the recent "Science and Technology" magazine that this action "may be helpful for remitting the release the carbon and the disappearance of biological diversity." Haywood said that if we want to know how great change we have done to the environment, standardization will be "a very strong illustration". Scientists are seriously dealing with the problem about the change of geological chronology. Here they are tackling the problem of time interval.
