The relationship between humans and the state of the ecosystem is not only
dependent upon how many people there are, but also upon what they do. When there
were few people, the dominant factors controlling ecosystem state were the
natural ones that have operated for millions of years. The human population has
now grown so large that there are concerns that they have become a significant
element in ecosystem dynamics. One of these concerns is the relationship between
human activities and climate, particularly the recent observations and the
predictions of global warming, beginning with the alarm sounded by W. Broecker

The relationships among humans, their activities and global temperature can be
assessed by... View More »

A vertical dashed-line has been placed at 1995. Filled symbols for the

are for values projected into the short-term future.

The first surge coincides with the beginning of the cultural revolution about
600,000 years ago, interrupted by the population crash 65,000 years ago.
Population size rebounded 50,000 years ago and then growth slowed considerably.
The second surge began with the agricultural revolution about 10,000 years ago
and was followed by slow growth. Deevey argued that moving down the food chain
was the underlying cause of this large and rapid spurt. The timing of the
present surge matches the rise of the industrial-medical revolution 200 years

A relation between innovation and population growth is embedded in the log-log
plot. There was rapid growth at the start of each surge. Then, growth rate
slowed as people adapted to the precipitating innovations. Each surge increased
the population more than 10-fold. It appears that we are nearing the end of the
present surge as recent growth rates have declined. After the initial spurt,
subsequent innovations did not perpetuate growth rates. The only significant
innovations were those that produced the next surge. However, accumulated
innovations during the surges may have played a role in the eventual decline in
population growth rates. Starting with high birth and death rates, death rate
declines and longevity increases, but birth rates stay high. Some time later,
birth rates decline so that ...

    Global Warming: A Threat or a Myth? There has been a steady increase in the temperature of the earth in the past few decades, and yet we are looking for an explanation for this increase. The historical warming of the earth’s surface over a period of time is known as global warming. Earth has observed a steady and evident increase in temperature, but people still ask if global warming is only a myth. “The Earth's average surface temperature has increased by about 1.2 to 1.4ºF in the last 100 years” (“Climate Change”). There have also been other changes in the environment such as the rain patt

    Global warming is a major threat in today’s world. In the last couple of years global warming has become a major problem because of several reasons. One reason is that many people in he past didn’t want to believe that global warming existed and that there were other explanations for what was going on. If the human race does not take global warming as a real threat there could be many severe consequences that could end up happening. The severity of global warming is causing the polar ice caps and other glaciers to melt at a faster rate then usual, also over the past couple of years the amount

    Global warming has become one of the largest arguments surrounding current scientific theories. Many researchers, scientists, and environmentalists are expressing their concerns about the changes the Earth is going through. Global warming is known as an increase in the Earth’s atmospheric and oceanic temperatures. The Earth’s temperature is rising, and there is no doubt about it. The nine warmest years of the century have occurred since 1980. Scientists have traced the beginning cause of global warming back to the beginning of the Industrial Revolution, a time when t

    a) Audience hook: The rise in the average temperature of earth is known as global warming. The average of temperature near earth's surface has increased dramatically over the last few decades (Samimi, 2011). Temperature increase in the planet is due to global warming. Scientists believe that even if the amount of global warming gases in Earth's atmosphere remain unchanged, its effects will stay in the atmosphere for centuries.. (Venkataramana, 2011). b) Thesis statement: Research suggests that human activity contributes to global warming through the use of fossil fuels and deforest

We have to know that what is global warming, why global warming is dangerous, and who has responsibility of global warming, finally how to deal global warming. Global warming is the gradual rise in temperature of the air and water near the earth's surface. The average temperature of the earth has risen about 1 degree Celsius over the past 100 years. Even though many people believe they know why this is happening, the exact cause is unknown. It could be caused by human activity; it may be caused by na

    The most prominent environmental crisis we face today is the threat of Global Warming. Global warming is indeed a serious issue in our world and is not just a myth. It is no longer a question what if global warming is real? But rather a question of how much and how fast global warming will affect us. A common misconception about the crisis is that the only effect global warming will have is a slight raise in the temperature of the earth. The reality is that the warming temperature is just the beginning of the changes the Earth will see. Many natural cycles we depend on
