give brief introduction on global worming?

Answer 1

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades.
The Earth's average near-surface atmospheric temperature rose 0.6 ± 0.2 degrees Celsius (1.1 ± 0.4 degrees Fahrenheit) in the 20th century. The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities". The increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced component of warming. They are released by the burning of fossil fuels, land clearing and agriculture, etc.
The measure of the climate response to increased GHGs, climate sensitivity, is found by observational studies and climate models. Doubling of CO2 in the atmosphere warms in the range 1.5-4.5 °C (2.7-8.1 °F). Models referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures may increase by between 1.4 and 5.8 °C (2.5 to 10.5 °F) between 1990 and 2100. The uncertainty in this range results from both the difficulty of predicting the volume of future greenhouse gas emissions and uncertainty about climate sensitivity.
An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors. Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global warming. Although most studies focus on the period up to 2100, warming (and sea level rise due to thermal expansion) is expected to continue past then, since CO2 has a long average atmospheric lifetime.
Only a small minority of scientists contest the view that humanity's actions have played a significant role in recent warming. However, the uncertainty is more significant regarding how much climate change should be expected in the future, and there is a hotly contested political and public debate over what, if anything, should be done to reduce or reverse future warming, and how to cope with the predicted consequences.
The term 'global warming' is a specific case of the more general term 'climate change' (which can also refer to cooling, such as occurs during ice ages). In principle, 'global warming' is neutral as to the causes, but in common usage, 'global warming' generally implies a human influence. However, the UNFCCC uses 'climate change' for human-caused change, and 'climate variability' for other changes . Some organizations use the term 'anthropogenic climate change' for human-induced changes.

Causes

The climate system varies both through natural, "internal" processes as well as in response to variations in external "forcing" from both human and non-human causes, including solar activity, volcanic emissions, and greenhouse gases. Climatologists agree that the earth has warmed recently. The detailed causes of this change remain an active field of research, but the scientific consensus identifies greenhouse gases as the primary cause of the recent warming. This conclusion can be controversial, especially outside the scientific community.
Adding carbon dioxide (CO2) or methane (CH4) to Earth's atmosphere, with no other changes, will make the planet's surface warmer; greenhouse gases create a natural greenhouse effect without which temperatures on Earth would be an estimated 30 °C (54 °F) lower, and the Earth uninhabitable. It is therefore not correct to say that there is a debate between those who "believe in" and "oppose" the theory that adding carbon dioxide or methane to the Earth's atmosphere will, absent any mitigating actions or effects, result in warmer surface temperatures on Earth. Rather, the debate is about what the net effect of the addition of carbon dioxide and methane will be, when allowing for compounding or mitigating factors.
Due to the thermal inertia of the earth's oceans and slow responses of other indirect effects, the Earth's current climate is not in equilibrium with the forcing imposed by increased greenhouse gases. Climate commitment studies indicate that, even if greenhouse gases were stabilized at present day levels, a further warming of perhaps 0.5 °C to 1.0 °C (0.9–1.8 °F) would still occur.

Answer 2

Over the last 100 years the average temperature of the Earth has risen with 0.7° celsius. As a result, apart from getting warmer, weather has become more extreme. More rain falls in less time, there are more hurricanes... etc.

We don't know yet the reason. It can be a climate change or the glasshouse effect, perhaps both at the same time.

In the future we can expect the situation getting worse.

Answer 3

First of all,it is Global Warming not Worming.Okay.let's start with pollution.Air polution causes global warming as discharging of harmful gases or smoke(Like CFCs by air con)therefore causing the ozone layer becoming thinner.When it becomes thinner,it allows more heat rays as well as more heat. Not only the temperature increases,it is also a threat to the Earth life as harmful rays such as UV rays reaches the Earth hence falling on the skins of Human Beings.When this happens,it will cause sin cancer and eyesight problems.

Answer 4

i hope u want to ask about global warming.

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades.

The Earth's average near-surface atmospheric temperature rose 0.6 ± 0.2 °Celsius (1.1 ± 0.4 °Fahrenheit) in the 20th century. The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities" [1].

The increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced component of warming. They are released by the burning of fossil fuels, land clearing and agriculture, etc. and lead to an increase in the greenhouse effect.

The measure of the response to increased GHGs, and other anthropogenic and natural climate forcings is climate sensitivity. It is found by observational [2] and model studies. This sensitivity is usually expressed in terms of the temperature response expected from a doubling of CO2 in the atmosphere. The current literature estimates sensitivity in the range 1.5–4.5 °C (2.7–8.1 °F). Models referenced by the Intergovernmental Panel on Climate Change (IPCC) project that global temperatures may increase by between 1.4 and 5.8 °C (2.5 to 10.5 °F) between 1990 and 2100. The uncertainty in this range results from both the difficulty of estimating the volume of future greenhouse gas emissions and uncertainty about climate sensitivity.

An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados.

Although most studies focus on the period up to 2100, warming (and sea level rise due to thermal expansion) is expected to continue past then, since CO2 has a long average atmospheric lifetime [3].

Only a small minority of climate scientists discount the role that humanity's actions have played in recent warming. However, the uncertainty is more significant regarding how much climate change should be expected in the future, and there is a hotly contested political and public debate over what, if anything, should be done to reduce or reverse future warming, and how to deal with the predicted consequences.

Answer 5

Global warming is the observed increase in the average temperature of earth's atmosphere and oceans in the recent decades. The reason for the warming is increase in carbon di oxide and other green house gases due to burning of forests and other causes. The effect of global warming will be increase in the pattern of rainfall and other precipitation, melting of ice, movement of glaciers, increase in water level of seas, floods, cyclones, hurricanes, ocean currents, deserts, draughts, famine.

This is a WORM that has come to the notice of international scientists and researchers. Majority of them agree that this worming is going to get worser and worser, before becoming worst.
