Arctic environment during an ancient bout of natural global warmingScientists are unravelling the environmental changes that took place around the Arctic during an exceptional episode of ancient global warming. Newly published results from a high-resolution study of sediments collected on Spitsbergen represent a significant contribution to this endeavour. The study was led by Dr Ian Harding and Prof John Marshall of the University of Southampton’s School of Ocean and Earth Science (SOES), based at the National Oceanography Centre, Southampton.Around 56 million years ago there was a period of global warming called the Paleocene–Eocene Thermal Maximum (PETM), during which global sea...

These are three of the dogmas which we are endoctrinated nowadays in school : #1 - origins of the current forms life forms: by evolution from previous forms #2 - appearance of Homo Sapiens (from encarta): The oldest known fossils that possess skeletal features typical of modern humans date from between 130,000 and 90,000 years ago. #3 - last ice age (from encarta): the most recent ice age, the Pleistocene Epoch, lasted from about 1.6 million years to 10,000 years before present ... when temperatures were 5° to 7° C cooler than today. #1 and #2 are part of current...
