The last 10,000 years of climate history are the years immediately following the Ice Age. Over these 10,000 years, the climate has invariably become warmer, as evidenced by the amounts of ice caps melting within the globe.
Climate change started in Britain with the Industrial Revolution, 200 years ago when we began to seriously burn fossil fuels (coal, oil and natural gas). This was the beginning of global warming.
Climate is an average of weather over several years, at least twenty or thirty. Climate is always changing, but changes in the past have happened very slowly, over thousands of years. Humans have never been able to change the climate before, but now, since we began burning fossil fuels, we have added so much greenhouse gases to the atmosphere that the world is warming up. This global warming is causing climate change, because heat is energy, and the extra energy in the oceans and atmosphere is changing our weather substantially. Over the years the climate changes.

people began to trade
more oxygen was consumed
From the very moment man began he had to hunt to eat. The first people were hunters and gatherers for food. Archeological evidence points that man began in Africa and eventually spread out.
