There are many, many people who live in those regions now.
There's just a simple chemical reason for that. My children will be in their 80s, perhaps with middle-aged children and grandchildren. Any study of climate change needs to take this into consideration. In the meantime, the effective capture from the air of today’s carbon emissions will with luck be a reality; they can be stored or used in the manufacture of materials.
This has led to miscommunication and an inadequate understanding of a planet that is best considered as a whole system.
If we allow 20 sq m of space per person – more than double the minimum habitable space allowed per person under English planning regulations – 11 billion people would need 220,000 sq km of land to live on.

Preparations range from engineering drought-resistant crops to building a Noah's Ark for world seeds in the Arctic. If you had been looking for a very long geologic time, you could have seen the continents themselves in motion, drifting apart on their crustal plates, held afloat by the fire beneath. It all started in the 60s when NASA invited Lovelock to a meeting. Greenhouse gases exist naturally in the atmosphere and are cycled through many natural pathways. In fact without the presence of carbon dioxide it is believed the temperature at the Earth’s surface would be 33° C lower than it is today. Climate - Climate - The Gaia hypothesis: The notion that the biosphere exerts important controls on the atmosphere and other parts of the Earth system has increasingly gained acceptance among earth and ecosystem scientists.
Furthermore an increase in global temperature will increase the concentration of water vapour in the atmosphere due to evaporation. Now there is a very strong evidence that certainly over the last million years that the climate system has regulated itself between glacial and interglacial periods and these are quite tightly constrained, with carbon dioxide levels typically between 280 and 180 parts per million. And as the ice melts, more dark ocean is exposed to the Sun and that warms the world even further which melts even more ice, which exposes even more dark ocean to the Sun, which warms the world even further...you get the idea, its another positive feedback. James Lovelock: The Earth has now passed the point of no return and is rapidly moving towards a hot state that it has been in before, a state it was in 55 million years ago. by Neil Meikleham. Norway will be a terrifically nice place to live. Life on Earth began at least as early as 3.5 billion years ago during the middle of the Archean Eon (about 4 billion to 2.5 billion years ago). Drowned cities; stagnant seas; intolerable heatwaves; entire nations uninhabitable… and more than 11 billion humans. We are wasting our time and energies on all the wrong things. In the broader picture of Gaia they are both positive and negative feedback mechanisms, both amplifiers and dampeners on any existing change. do not absorb infrared light. In fact, my work suggests that it may well not be, that the existence of life on Earth could accelerate climate change to some extent over the next 100 years. What you should be concerned with is a bit like the insurance problem, is the highest risk, and the highest risk can be actually a very high impact, like a very large climate change that is unlikely but could still the highest risk of all to the system you are in and human society. Science, on the other hand, was preoccupied with reductionism and triumphant in investigating the world in its finest details. Using this technique a continuous record of temperature over 160 000 years has been measured from samples from Vostok, Antarctica.
The story we must reject, I am suggesting, is that the Earth is nothing more than a dead machine that we can use and exploit as we wish. But now we've got an even more powerful reason which is that we have to preserve biodiversity if we want to have a climate on this Earth which is going to be suitable for us. Although they didn't quite share Lovelock's apocalyptic vision, there was a consensus that in our lifetime we'll face serious climate change.
Stephan Harding: For me, Gaia theory is so powerful because it has very important scientific implications, but perhaps more important than that it has incredibly serious and important philosophical implications for the way our culture lives in nature. The trees themselves evaporate large quantities of water through their leaves.
