Global warming caused by greenhouse gases delays natural patterns of glaciation suggests a study co-authored by a University of Florida researcher and published online Jan. 8 in Nature Geoscience.
The Earth's current warm period that began about 11,000 years ago should give way to another ice age within about 1,500 years, according to accepted astronomical models. However, current levels of carbon dioxide are trapping too much heat in the atmosphere to allow the Earth to cool as it has in its prehistoric past in response to changes in Earth's orbital pattern.
data indicate that the next ice age will likely be delayed by tens of thousands of years.
Good news ...?
Ice sheets like those in western Antarctica are already destabilized by global warming, they eventually slough off and become a part of the ocean's volume, it will have a dramatic effect on sea level.
