Demise Of Ice Ages?
Long Debate Ended Over Cause, Demise Of Ice Ages? Research Into Earth’s Wobble
Glacial period has been a long discussion of research and information organizations. In the world of the past 250 million years – they will be linked to small changes in solar radiation at the omen of the end. Changes in the world due to the spin axis.
Printed in the Friday issue of Science magazine will be released in the known world and other agencies in Oregon State University researchers wobbles, the rotation of the world reach the 26,000 level of the conclusion on the ice before them, 7000, and continued melting began 19,000 years ago, please preface to the last ice age.
Changes in solar radiation but also caused the dissolution of the first. Carbon dioxide levels, ocean temperatures, scientists, or some people have suggested. In recent years,
“Melting of ice called the solar radiation is now that a lot,” geology professor Peter Clark in Osu. “Climate change, but carbon dioxide levels and ocean circulation, and then is amplified, it occurred to start the process.”
Important results, the mechanism of radiative forcing can tell scientists and researchers to understand more precisely the melting of ice sheets in response to any of the 19,000 years ago, solar radiation What to expect from today’s emissions will change due to the increase in the amount of interpretation and can be painful. Support the world’s ice sheets to more accurately project and scientists has grown from a tree that corresponds to the future look like?
“The ancient ice sheets are very confident that I know now, solar radiation and the response. Very good, and future,” Clark said, “this is to understand whether there is anything that is a good lead in this be useful on. ”
For analysis, the researchers, and date, analysis of a high level of accuracy to determine the position of the ice sheet is 6000 they have been refining their start, in theory this is the first in 1950 In the world of spin is more developed, and then point to a small but changing the definition. Asked the age of the ice.
“The year 5000 and 10,000,” Clark said, “Jupiter in the main draw of the large planets, such as a slightly different location and get affected by Saturn ทัต these off-balance, calculate the change in the axis of rotation of the Earth You can. thousands of years in the range of means. ”
In its turn, can change the heart of the world – it is a very long way to the sun – over a long period of sunlight that changes the way in, about twice the number of planets to make those small changes in solar radiation The strike can occur. Ice age. About 2.5 million people last year, reaching about 10 million people each year, an extreme world.
Scientists can now say there is a need to change the world one million years ago and lasted a long time to return to the original lead to another ice age – has been slow, stop or part . However, the glacier to move slowly because of the gas in these processes, for sure. Greenhouse gas emissions, the world warmed in the past 200 may be healing for thousands of years to Clarke in a year.
“One of the biggest concerns is now in the Antarctic and Greenland ice sheets, in response to global warming, contributing to high sea level,” and Clark, “This is a process we are improving and It is said to help you understand. to the model. ”
Canada, University of Wisconsin, Stockholm University, Harvard University, to conduct research with scientists from the Geology of the U.S. Geological Survey and University of Ulster, this exploration has been supported by the National Science Foundation and other organizations.
