Ancient global warming caused tropical forest diversity

New research is showing that during a global warming phase 56.3 million years ago, tropical forests thrived. Researchers examined pollen trapped in rock cores and outcrops—from Colombia and Venezuela—formed before, during and after an abrupt global warming event called the Paleocene-Eocene Thermal Maximum that occurred 56.3 million years ago. The

Gassy fact: Mammoth farts contributed to global warming

Apparently, 13,000 years ago Mammoths helped fill the atmosphere with methane, altering the climate. Together with other large plant-eating mammals that are now extinct, they released around 9.6 million tonnes of the gas each year, experts estimated. When the ''megafauna'' disappeared there was a dramatic fall in atmospheric methane which

Scientific evidence for the Biblical plagues

Scientists are claiming that the Biblical plagues that devasted Egypt in the Old Testament were the result of global warming and a volcanic eruption. The scientists believe this switch in the climate was the trigger for the first of the plagues. The rising temperatures could have caused the river Nile

Agricultural methods Of early civilizations may have started global warming

The massive burning of forests, for agricultural reasons, thousands of years ago may have increased the level of carbon dioxide in the atmosphere enough to alter the climate, ushering in a warming trend that continues to this day. Researchers at the University of Virginia and the University of Maryland-Baltimore County say

Global warming did not destroy Ancestral Puebloan civilization

A new research study has demonstrated that global warming did not contribute to the demise of the Ancestral Puebloan civilization. The people had managed droughts much more severe than the early 12th century dry period and, Dr. Skopec adds, much of their land could have supported even larger populations. Their abandonment of
