Is there a place on earth where it is too hot to for life?

Answer 1

First of all, the Earth is not a living organism and therefore cannot be killed. It can be destroyed, by, say, a collision with an asteroid the size of Texas. Or, as the first post mentions, the explosion of our own sun. But, second, global warming cannot destroy the Earth.

If temperatures keep increasing for the next 10,000 years (depending on the rate of temperature increase - at the current rate it will take 10,000 years), all life on Earth (with the exception of a few microscopic organisms) will become extinct. But the Earth will still be here.

That said, "global warming" is completely natural in origin. Just like it has always been, throughout the Earth's history. In fact, it has happened three times in just the last 3,500 years, and the current event falls right in line with the cycle. There is absolutely nothing unique about either the current temperature levels or the rate at which temperatures are increasing. Several hundred times in the last 10,000 years, temperatures have been higher than they are now. And at least 50 times in the last 10,000 years, temperatures have changed more rapidly than they are changing now.

We know that the Earth's natural climate system is dominated by negative feedbacks. After 5 billion years of climate change, caused by thousands of meteor impacts, orbital wobbles, polar reversals, insterstellar dust clouds, nearby supernova, and a dozen other natural causes, the Earth is still here, and there is still life on it. If the system was dominated by positive feedbacks, the first meteor impact of any size would have set of a chain of events that, within a hundred years, would have caused runaway climate change, and all life on Earth would have perished. Clearly, that never happened. And therefore, the climate system is not dominated by positive feedbacks.

Rest assured, the current warming trend will reverse itself shortly. In fact, it appears that the reversal has already begun. For all we know, a La Nina is part of the Earth's negative feedback system. In any event, we know that all natural warming events in the past have eventually reversed themselves. And since the current warming is natural, it too will reverse itself.

Answer 2

At some time in the distant future scientists expect that the sun will turn into a red giant star and expand considerably in size. When it does the earth will actually be absorbed by the sun. In the much nearer term, it is also possible that global warming will cause the Earth to become too hot to sustain life. But even that, if it does happen, will take time. No need to prepare for an immediate demise. Our Sun is gradually becoming more luminous (roughly about 10% every 1 billion years), and due to this its surface temperature is also slowly rising. The Sun used to be fainter in the past, which is one possibility why life on Earth has only existed for about 1 billion years on its surface. The increase in solar temperatures is such that in about a billion years, the surface of the Earth will become too hot for liquid water to exist, potentially ending all terrestrial life.

Answer 3

Yes, there are some places on Earth, such as the barren deserts like the Lut Desert in Iran and the Death Valley in California, where the extreme heat and lack of water make it very difficult for most forms of life to survive. However, even in these harsh environments, some organisms like certain types of bacteria and insects have adapted to live there.

Answer 4

On the surface, no. As long as you have a water supply, you can live just about anywhere through adaptation. Under the Earth's surface, however, after a mile or so down, no life can survive.
