If we go back to the era that existed 22,000 years ago, we will find ourselves in a completely different zone. With Boston covered in ice and glaciers visible from the city of Newyork, the world feels much colder than it is today. Fast forward to 19500, when people are beginning to settle down in Australia, Africa and Eurasia. For the sake of basic necessities of life, people have started to craft to produce handmade ropes, pottery etc. After a thousand years later, the polar ice of the earth is exposed to the sunlight, which becomes evident five decades later in the form of melting ice sheets.
The picture gets even worse when a combination of Carbon dioxide and heat starts to take a spike. This boosts the level of heat emanating from the sun. In order to combat this climate change, reconstruction projects have been initiated. By the time earth is 14500 BCE old, a land bridge connecting North America and Asia is coming to the attention of people as a result of melting ices sheets in Alaska. The iceberg which first was entitled to New York has now shifted its location to Canada. After 13000 BCE, the earth loses its Wooly Rhino species, and monstrous floods break out in Washington as the dams containing glacial water burst and find their way to the sea. By 8000BCE, people have moved to Jericho, North America has lost its horses, the Canadian border no longer sustains ice sheets, and the temperature has taken a toll. North America loses its only ice sheet, which causes a rapid increase in the sea level. As humans have collected their pace and started to learn copper metalworking, working of the wheel, etc., the climate is observed to go downhill simultaneously.
By 500 BCE, all the civilizations, invasions, creation of Greek cities and extinction have taken place. After 1 CE, the Roman Empire is introduced along with the history of Muhammad. Ghenghis Khan and his famous tales are echoed everywhere. Events like the introduction of Newton and Shakespeare, the revolution of industries and nuclear weapons, the invention of aeroplanes as well as the internet have successfully occurred by the time earth is in the year 2000.
The present-day suggests that the Northwest Passage is in danger with an extensive rise in the levels of Carbon dioxide.
