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&39;s environment from hot to cold, wet to dry and back again over a time period stretching back hundreds of millions of years.
Most important. scientists are beginning to realize that the climatic changes have bad 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(灵长目动物) 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 environment summit in Rio. Among other things, the findings demonstrate that dramatic climate change is nothing new for planet Earth. The benign(宜人的) 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&39;s climate will almost certainly go through dramatic changes in the future-even without the influence of human activity.
