what is global warming ?

Answer 1

Global warming is a phenomenon in which th temperature of earth atmosphere increases considerably over a span of many years. this unbalances the sensitive ecological balance. this can also cause an ice age sort of situation due to melting of polar ice caps.

Answer 2

global warming is where the earth's temperature is increased due to greenhouse gases. Normally when the heat from the sun comes to earth some of is reflected and some of is sent back in to space. When these greenhouse gases build up in the atmosphere the heat that is trying to escape from earth is blocked by the gases thus causing global warming

Answer 3

Increase in the concentration of of carbon di oxide and some other gases in the atmosphere results in an increase in the temperature of atmosphere, which is know as global warming.

Answer 4

1. Global Warming has caused holes
in the Ozone layers of this planet.

2. These holes cause transmission of
ultra violet radiations to earth, harmful for our
planet, as it cannot filter emmissions from
sun and other planets.

3.Extra heat is thus transmitted again to earth.

4. The ruptures in the Ozone layers are caused
by excessive heat generated in the earth, by way
of Co2 as well. These heat are also caused by rapid industrialisation and smoke emmissions by many
countries.

5. The heat genarated by power plants, fertiliser
plants, chemical plants, pesticides plants, steel
plants, foundaries, forest fires, etc., have damaged the Ozone layer.

6. The heat thus generated, cause excessive and
untimely rainfall, floods and typhoons.

7. Because of too much heat, there are no snow falls
in most of the places, where it used to snow during the
winters.

8. Ice bergs and glaciers are melting rapidly due
to this excessive heat, resulting in increase of sea levels.

9. Most of the industiralised countries like Australia,
USA etc., are not following the heat emission norms.

10. Almost all countries signed the KYOTO Protocol,
to ensure that heat emissions are restricted, but
only USA and Australia did not sign the agreement,
and they are blaming the poor countries for
the heat emission, which is simply rubbish and non-sense.

Answer 5

increase in the concentration of CO2 and some other gases in the air results in an increase in the temperature of the atmosphere, which is known as global warming.

Answer 6

due to the increase of temperature the antarctica and arctic regions melt and the sea level increases . the increase in temperature is by globalwarming. by the absorption of greenhousegases the globalwarming increases

Answer 7

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades and its projected continuation. Models referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures may increase by 1.4 to 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.

The scientific community has reached a strong consensus regarding the science of global climate change. The world is undoubtedly warming. This warming is largely the result of emissions of carbon dioxide and other greenhouse gases from human activities including industrial processes, fossil fuel combustion, and changes in land use, such as deforestation. Continuation of historical trends of greenhouse gas emissions will result in additional warming over the 21st century, with current projections of a global increase of 2.5ºF to 10.4ºF by 2100, with warming in the U.S. expected to be even higher. This warming will have real consequences for the United States and the world, for with that warming will also come additional sea-level rise that will gradually inundate coastal areas, changes in precipitation patterns, increased risk of droughts and floods, threats to biodiversity, and a number of potential challenges for public health.




Addressing climate change is no simple task. To protect ourselves, our economy, and our land from the adverse effects of climate change, we must ultimately dramatically reduce emissions of carbon dioxide and other greenhouse gases. To achieve this goal we must fundamentally transform the way we power our global economy, shifting away from a century’s legacy of unrestrained fossil fuel use and its associated emissions in pursuit of more efficient and renewable sources of energy. Such a transformation will require society to engage in a concerted effort, over the near and long-term, to seek out opportunities and design actions to reduce greenhouse gas emissions.

Global 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 observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations." [1] The main cause of the human-induced component of warming is the increased atmospheric concentration of greenhouse gases (GHGs) such as carbon dioxide (CO2), which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Greenhouse gases are released by activities such as the burning of fossil fuels, land clearing, and agriculture.

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.

Answer 8

increase in sea water level due to melting of ice & increase in the temperatureof our planet
