Recently, the Change of the global climate brings about the fatal disasters all over the world. It not only worries the world’s population but also troubles the scientists the world over. When global warming finally came it stuck with a vengeance. In some regions temperatures rose several degrees in less than a century. Sea levels shot up nearly 400 feet flooding coastal settlements and forcing people to migrate inland. Deserts spread throughout the world as vegetation shifted drastically in North America Europe and Asia. After driving many of the animals around them to near extinction people were forced to abandon their old way of life for a radically new survival strategy that resulted in widespread starvation and disease. The adaptation was farming the global-warming crisis that gave rise to it happened more than 10 000 years ago.
As environmentalists convene in Rio de Janeiro this week to ponder the global climate of the future earth scientists are in the midst of a revolution in understanding how climate has changed in the past--and how those changes have transformed human existence. Researchers have begun to piece together an illuminating picture of the powerful geological and astronomical forces that have combined to change the planet’s environment from hot to cold, wet to dry and back again over a time period stretching back hundreds of millions of years.
Most importantly, scientists are beginning to realize that the climatic changes have had a major impact on the evolution of the human species. New research now suggests that climate shifts have played a key role in nearly every significant turning point in human evolution from the dawn of primates some 65 million years ago to human ancestors rising up to walk on two legs, from the huge expansion of the human brain to the rise of agriculture. Indeed the human history has not been merely touched by global climate change. Some scientists argue it has in some instances been driven by it.
The new research has profound implications for the environmental summit in. Rio. Among other things the findings demonstrate that dramatic climate changes is nothing new for planet Earth. The benign .global environment that has existed over the past 10 000 years—during which agriculture writing cities and most other features of civilization appeared--is a mere bright spot in a much larger pattern of widely varying climate over the ages. In fact the pattern of climate change in the past reveals that Earth’s climate will almost certainly go through dramatic changes in the future--even without the influence of human activity.
