Last glacial period

the Younger Dryas. This period of glacial activity occurred around 10,800-10,600 BP and was the last great real push of ice activity in the British Isles starting around loch Lomond and fanning out across Scotland. The ice itself covered a large part of Britain as lowered temperatures of around 2- 6 degrees Celsius allowed the ice to remain, locking in large amounts of sea water and shaping the landscape as it moved across the land, creating U-shape valleys and other glacial features such as drumlins

into an extraordinary voyage of time as space. From the beginning of times, the place has been forming with three receding glacial successions and their beautiful ornaments of rocks, limestone, and basalt. Glacial movements have left an excellent bed with nutritious deposits and ice

they provided more food. The climatic hypothesis suggests that the end-Pleistocene extinction of megafauna was a result of major climatic changes occurring at the end of the Pleistocene. The timing of the last glacial interval is appropriate for the climatic hypothesis, as the last glacial interval ended in many places, including North America, between 12,000 and 10,000 years ago. [7]. Similarly, many extinctions occurred in North America around this time, such as that of the American cave lion

Introduction With ever-growing resources and new technology, scientists now possess the ability to analyse data that was not available decades ago, the data from different proxies such as ice core analysis, pollen analysis, oxygen isotope analysis and radiocarbon dating of organic materials allows for the study of the behaviour of the ice sheets which cover 10% of the Earth’s surface. Ice sheets currently hold approximately 70% of all the freshwater. The Antarctic Ice Sheet in the Southern Hemisphere

continuum throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, the end of the last ice age occurring about 11,700 years ago. With climate change being a seemingly characteristic and even beneficial quality of Earth (the end of the ice age did mark the beginning of the modern climate era fit to sustain human civilization after all) it may be easy to disregard the significance of the current period of climate change our planet is in. However

more tropical storms and hurricanes causing massive destruction, more animal species losing their habitats and coming under threat, rising sea levels, etc. According to NASA, the hottest year on record was 2005, which was the same as 1998. In the last ten years, twice we’ve had record temperatures ever recorded in our planet’s history. The past nine years have all been among the 25 warmest years on record. 2 WHAT IS GLOBAL WARMING? Global warming is the gradual rise in average surface temperature

With the work of other scientists who had theorized about horizontal movement of the continents over the earth’s surface during different periods of geologic time, and based on his own observations from different fields of science, Wegener deduced that about 200 million years ago the supercontinent that he called “Pangaea,” (means “all lands” in Greek) began to break up. Evidence Many people

The Holocene Epoch is the timescale given to the last 11,700 years of earth’s history, beginning at the end of the last ice age. (BD Smith et al, 2013) Therefore it can be noted as being a relatively warm period in history in comparison to other scales of time from the past. The Early Anthropogenic Hypothesis is an idea put forward by Professor William F Ruddiman from the University of Virginia which states that the effects of human-induced greenhouse gas emissions did not occur simply since the

Prehistoric man has endured misinformation, stereotypes, and a lack of information. The Upper Paleolithic Epoch started 40,000 years ago and goes on until about 12,000 years ago and glacial ice was on the move. Periods of extreame cold were cycled with warmer weather. The habitats of humans and animals was undergoing great and significant changes. Herds of wooly mammoth were moving about, hunter-gathers were following. Through recent discoveries and expansions on old theories, prehistoric man began
