What is the description of global warming?

Answer 1

Global warming is a major issue because the entire environment, indeed the planet Earth is dramatically affected by climate change. There are many factors that are involved in the Earth's climate change and there is much that the scientific community does not know about the stability of this planets climate. There are many scientist of late however, who have suggested and even suggested strongly that it is human activity since the advent of the industrial revolution that has created the current global warming trend. It is important to understand that the current warming trend on this planet is not new and the last time Earth went through a similar warming was the Medieval Warm Period from about 800-1300 AD. The Medieval Warm Period was followed by a cooling period known as The Little Ice Age that lasted until the 19th century. The planet today is now experiencing a warming period that is speculated to be warmer than any period known to man. This sounds alarming but the reality is that the last warming period was only slightly cooler than today estimated to be around 0.03 degrees Celsius cooler than today. That slight difference can amount to a noticeable difference in environmental changes or not it is unclear based on the current data available.

Whether global warming is a survival issue for humanity is just not clear. That it is a major political issue is more than obvious. The United Nations has strongly advocated major intergovernmental action in slowing down the effects of global warming. It is not at all clear that the effects of global warming can be slowed but this doesn't deter politicos with visions of a one world government and they will subvert the truth and use only the data that supports their urgent and dire claims that only a strengthened and powerful government can save humanity from their own hubris. The U.N. has presented the world with a "scientific" report signed by some 2300 scientist known as the Intergovernmental Panel on Climate Change or IPCC, this report claims that there is a 90% certainty that human activity is the cause. 90% certainty is not certainty it is still chance just the same as a 9% certainty is. The science used to come to this "certainty" is based upon incomplete computer models that suggest it is human activity that has caused the current global warming trend.

Even though these computer models are incomplete and do not present a realistic model of Earth's climate, they still could be right in their determination that it is human activity that is causing the warming. Human activity is certainly causing some of the warming there is little doubt to this. It is self evident that human activity affects the environment and it should come as no surprise that human activity can affect the climate. What is not self evident is that the current warming trend is a vital threat to our survival. What is not self evident is that human activity is the sole cause of the current warming trend and what is not self evident is that the climate of the past few hundred years is the ideal climate for a planet populated by more than 5 billion people. Because there is so little that is self evident, and all that is certain is that we are in a warming trend, the issue is major because it is contentious. Uncertainties lead to speculations, speculations lead to theories, unprovable theories lead to dogma and adherents of dogma form religious groups who advocate the dogma. Religion is a necessary component of any society but religion is not science. There are no dogmas in science and what science can not prove, scientists should avoid speaking to. Prove or disprove a theory this should be the primary goal of science. Forming political movements to advocate a particular theory will neither prove nor disprove the theory, that happens in the rigid testing and experiments formed to successfully predict outcomes and explain the outcomes and the cause is what will ultimately prove or disprove a theory.

While global warming continues to grow as a political movement it is important for everyone to educate themselves on how science works and how theories are proven and dis-proven otherwise people will remain vulnerable to shameless Propaganda. One can not learn all there is to know about global warming by reading glossy brochures and skimming through earnest and ardent web pages that offer out of context data as science. Ambitious politicians seeking expanded power are counting on the probability that you will not do all that is necessary to learn the facts and will instead rely on the Propaganda provided you. Don't fall prey to propaganda, do what you must to know for yourself what is true and what is not true. Don't take anybodies word as truth, discover the truth for yourself.

Answer 2

Global warming could be influenced by a variety of factors. Millions of years ago a salt water fern absorbed CO2 from the atmosphere. As the ferns died they sank and that carbon became sequestered on the deep sea floor. The result was a gradual cooling of the climate.

Volcanoes also vent a lot of hydrogen sulfide gas and particulate matter that reflects sunlight, resulting in cooler temperatures.

Since the beginning of the industrial revolution, however, mankind has begun burning coal--much of which was carbon sequestered during the Permian some 300 million years ago, or during the later Mesozoic. In a short time (150 years) atmospheric CO2 levels have risen from 280 parts per million to over 390 ppm today. As we continue to pump 30 billion tons of CO2 into the atmosphere each year from fossil sources, this heat trapping gas will result in an inevitable rise in global temperature.

Answer 3

Global warming is a rise in the average temperature of the Earth. It most often results from increases in green house gases, such as carbon dioxide and methane. These gases trap heat energy of the Earth. This raises the temperature of everything on Earth. Then, as glaciers and ice melt, the warming affect becomes amplified and accelerated. This is because glaciers and ice reflect almost all sunlight that falls on them back into space. When they melt, it opens up large areas of dark land and water which do the opposite: they absorb almost all of the sunlight and this further heats the Earth, which melts even more ice and glaciers. It's a self-reinforcing, self-accelerating phenomena. There are also trapped green house gases in permafrost that get released into the atmosphere as the Earth warms. Again, amplifying the warming effect, which then causes even more gases to be released from permafrost and even more ice to melt, which then warms the Earth even more in an endless feedback loop of warming. The reverse is also true. During the ice ages, there is so much ice on Earth, and so much of the green house gases are trapped in permafrost that ice ages end up lasting thousands of years before something significant alters the climate. So, it's possible that if global warming continues, a critical point may be reached. A point of no return that, like an ice age, could last for thousands of years. If this point is reached, then global warming will rapidly increase in a runaway type effect that can no longer be reversed after it is reached (at least not for a long time). And as the oceans warm, more water evaporates to create more intense hurricanes and storms. Ocean currents may also change, causing drastic climate changes. Some areas may even become colder, or snowier as a result (but the overall average Earth temperature is higher). As ice and glaciers melt, ocean levels will also rise, causing coastal areas to slowly become submerged under water.

Answer 4

well global warming is here or is comming and people believe that it's happening now. and scientist believe the pollution is the cause of it. so that's what I think is happening

Answer 5

Global warming is brought about by greenhouse gas emission. This gases are normally released when industries use fossil fuels and other forms of non-renewable energy.

Answer 6

How are We to explain the melting of all of Our {The} Earth's Glaciers.

Acidification of Our Oceans is next on the List.

Answer 7

Global warming community is becoming louder as in dangerous which mainly on what's being produced by burning fossil fuels and forests.also short lived pollutants like black carbon.

Answer 8

Warming of the earth by excess of greenhouse gases

Answer 9

its bad
