Introduction
Global warming happened in 1980’s. As Mark Lynas speculated, in only a few decades it completely changed the landscape of Earth so put human civilization into a grave danger. (Mark Lynas, 2008) Nonetheless, when global warming brought catastrophes, destroyed the old urban systems, it also brought new opportunities. On the ruins of the old world, many urban and architectural conceptions are carried out, such as 3d city, skycar city, hyper tower, and capsule dwelling etc.. As a record of people’s living condition in 2090, this essay will discuss global land use function, urban model and architectural form in this drastic renovation.

Four Stages of the new balance

Before the arrival of a new balance in 2090s, there were four stages in human race’ responding to global warming. The first one was a collective denial. At the beginning, global warming only impacted on the marginal zones of human living environment. The disasters caused by climate change appeared to be only a series of random phenomenas, so the majority of society was blunt to it. Even the minority had become aware of its possible disastrous consequences, before the reality came, the majority kept focusing on their immediate interests. The second stage was great chaos. When the gradual accumulation of local changes finally led to drastic global catastrophes which human could not interfere, the society was suddenly full of collective panic for the coming of doomsday. People lived in mass riots for taking advantage of society turbulence and local wars for living resources. The third period was a global migration. The weakness of human technology used to resist natural catastrophe completely exposed at that time. Climate refugees numbered in the hundreds of millions, therefore they had to migrate from the sanded field and flooded land to the last habitable latitude zone, which was between 40°N and 70°N. Finally, a new balance between the human and the nature came. Due to the rising of temperature, the high latitude area today has tropical climate. The relatively increased grain production finally is able to meet the demand of the greatly reduced world population. To locate the four stages in a time line, the collective denial happened in early 21st century, the great chaos broken out 30 years later, the global migration followed closely and the new balance comes in 2090 and is expected to last about a century.
