An ice age, or more precisely, a glacial age, is a period of long-term reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental ice sheets, polar ice sheets and alpine glaciers. Within a long-term ice age, individual pulses of cold climate are termed "glacial periods" (or alternatively "glacials" or "glaciations" or colloquially as "ice age"), and intermittent warm periods are called "interglacials". Glaciologically, ice age implies the presence of extensive ice sheets in the northern and southern hemispheres. By this definition, we are still in the ice age that began 2.6 million years ago at the start of the Pleistocene epoch, because the Greenland, Arctic, and Antarctic ice sheets still exist.
In a fantastic discovery, a team of Chinese and US archaeologists have come across fragments belonging to a 20,000 year-old bowl in modern day China, confirmed as the earliest evidence of pottery. The findings push back the invention of pottery by 10,000 years and suggest that human were more socially advanced than previously thought. The pottery fragments [...]
In the darkest caves of southwest China, one can experience fragments of the long set Ice Age and travel back in time 30,000 years. No, there isn’t any time machine or stargate of some sort (scientists say time travel is impossible, I beg to differ), instead what you’ll find in one of the darkest corners [...]
Global warming is the main concern on everybody’s lips, causing more and more damage to the environment every year, sometimes in ways that seem hard to believe; everyday there seems to be a new report about something that went, is going, or will be going terribly wrong. However, in the early 1800s, the situation was [...]
An amateur Dutch archaeologist named Jan Meulmeester made a startling find which pleases scientists: an amazing collection of 28 flint hand-axes, dated by archaeologists to be around 100,000 years-old. He found them in an area about 13km off Great Yarmouth. Jan Meulmeester diggs regularly for mammoth bones and fossils in marine sand and gravel delivered [...]
Basic paleoclimatology and one a little more There have been many climatic shifts throughout the geologic period of our time. The abrupt climate change events that occurred thousands of years ago are very important to us because they took place closer to this day and so there is a greater chance of repeatability. We [...]
