What is 'GLOBAL WARMING'?

Question

What is 'GLOBAL WARMING'?

Answer 1

Global Warming is were the Earth is heating up at a rapid pace. If the Earth even heats up a few degrees it could rec havoc on the Polor ice caps. (Scientist predict that the Polor ice caps with be totally melted by 2020 is people keep acting as they do know). Global Warming is caused by pollution and other bad things to the environment!

Answer 2

Let me start off by saying we (my family and I) live 100% off of the grid and are completely self-sufficient with a 0% Carbon footprint. I believe this is the first step anyone can make “help the environment”. Once you convert your own life style to a greener more eco friendly route, you can start helping others.

We definitely didn't start global warming, but we definitely do contribute to it now.

Natural gas (or Methane along with other thanes) for example, is completely a natural contributer to global warming and is derived pretty much the same way as oil. ie. Matter (animal, plant etc) decomposes over time resulting in a anaerobic (hope I spelled that right) decay of non-fossil organic material / gas (natural gas or methane).

One problem with global warming is that the concept is so vague in the minds of the people. The critical interpretation is basically how it’s explained in school and the news. However most of the public see global warming connected with the ozone and pollutants which cause harmful greenhouse gasses, etc. therefore investigating and fighting for things like alternative energy (ie. Solar, wind, hydrogen, ethanol, biodiesel, etc)

Greenhouse gases are real and do contribute to global warming. Think of the different gas layers like ozone (o3) that circumference the globe as the clear plastic on a greenhouse. Longer rays of light from the Sun go in and reflect off different thermal masses bouncing back and creating shorter lengths of energy that cannot exist the plastic barrier. These beams then just continue to bounce around inside the green house until they’re finally absorbed completely (some do escape but very few), thereby warming the greenhouse greatly even in cold temperatures.

Basically there are 2 ways that this reaction (or lack of) affects the planet. Global warming and global cooling.

1. as we add to the gases in the stratosphere, where the ozone layer is (Carbon dioxide, carbon monoxide, etc), we add to the plastic of the greenhouse, trapping more short wave length energy and heating the earth more.

2. as we deplete the ozone (with chlorofluorocarbons or CFCs), we allow more long wave length energy, which bounces back out to space without heating any thermal masses on earth, thereby cooling the planet.

It’s pretty easy to see the results..

Melting ice sheets & glaciers

Floods & droughts

Great hurricanes & cyclones

Seasonal extremes

Seasonal phenomena’s

Species extinction

New & resurgent diseases

There are many ways to stop both global warming and cooling from accruing or at least slow them down until we can discover a way to reverse it, but Stop burning fossil fuels is the biggest.

I currently own 2 converted h2 vehicles which run on 100% hydrogen and 1 EV (electric vehicle), not to mention our home is completely off the grid, using alternative energy (solar, wind, etc)

Stop Global Warming!!!

Answer 3

The naturally occurring rising of the planets temperature that has happened many times before and it is just a cycle.

Answer 4

lol* every1 knows about it.

It's the heatning up of earth coz the solar energy gets trap between the ground & green house gases like co2 , CFC's etc.

in brief: earth absorbs 25% of heat & rest is radiated back but these green house gases don't let that heat go out of earth.so they bounce back which increases the temp.

Answer 5

its when all the gases cause a shild around the earth and the gases can't get out so the sun heats the gases and it causes the weather to go wacky

Answer 6

Global warming is the effect of warming of our atmosphere. For details and other issues on environment, please refer blog - http://www.environmentengineering.blogsp...

Answer 7

hi, Iam Manoj

According to me global warming takes place due to increasing green house gases like co2&co .This occurs due to depletion of ozone layer around the earth.as a result the icecaps and glaciers are melting away &there is an increase in 1.56% of water in the sea level.The need of the hour is toreduce the pressure on ozone layer by using less of fossil fuels and controlling the level of green house gases by restricting the use of these gases.

Answer 8

Global warming is that the planet is heating up due to the matter of pollution caused by humans.

Answer 9

I think you have got it.

Answer 10

the biggest fallacy to ever be imposed on the American people

Answer 11

Global warming is that the planet is heating up due to the matter of pollution caused by humans. However, many believe this is a conspiracy by the goverment to make the public spend more money.

Answer 12

an increase of the earth's temperature by a few degrees resulting in an increase in the volume of water which contributes to sea-level rise

Answer 13

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century and its projected continuation.

The average global air temperature near the Earth's surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005.[1] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations"[1] via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.[2][3] These basic conclusions have been endorsed by at least thirty scientific societies and academies of science,[4] including all of the national academies of science of the major industrialized countries.[5][6][7] While individual scientists have voiced disagreement with some findings of the IPCC,[8] the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions.[9][10]

Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century.[1] The range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans.[1]

Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions, but there is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.

Causes

The Earth's climate changes in response to external forcing, including variations in its orbit around the Sun (orbital forcing),[14][15][16], changes in solar luminosity, volcanic eruptions,[17] and atmospheric greenhouse gas concentrations. The detailed causes of the recent warming remain an active field of research, but the scientific consensus[18][19] is that the increase in atmospheric greenhouse gases due to human activity caused most of the warming observed since the start of the industrial era. This attribution is clearest for the most recent 50 years, for which the most detailed data are available. Some other hypotheses departing from the consensus view have been suggested to explain most of the temperature increase. One such hypothesis proposes that warming may be the result of variations in solar activity.[20][21][22]

None of the effects of forcing are instantaneous. The thermal inertia of the Earth's oceans and slow responses of other indirect effects mean that the Earth's current climate is not in equilibrium with the forcing imposed. Climate commitment studies indicate that even if greenhouse gases were stabilized at 2000 levels, a further warming of about 0.5 °C (0.9 °F) would still occur

Greenhouse gases in the atmosphere

The greenhouse effect was discovered by Joseph Fourier in 1824 and was first investigated quantitatively by Svante Arrhenius in 1896. It is the process by which absorption and emission of infrared radiation by atmospheric gases warm a planet's lower atmosphere and surface.

Existence of the greenhouse effect as such is not disputed. Naturally occurring greenhouse gases have a mean warming effect of about 33 °C (59 °F), without which Earth would be uninhabitable.[24][25] On Earth, the major greenhouse gases are water vapor, which causes about 36–70% of the greenhouse effect (not including clouds); carbon dioxide (CO2), which causes 9–26%; methane (CH4), which causes 4–9%; and ozone, which causes 3–7%.[26][27] The issue is how the strength of the greenhouse effect changes when human activity increases the atmospheric concentrations of some greenhouse gases.

Human activity since the industrial revolution has increased the concentration of various greenhouse gases, leading to increased radiative forcing from CO2, methane, tropospheric ozone, CFCs and nitrous oxide. Molecule for molecule, methane is a more effective greenhouse gas than carbon dioxide, but its concentration is much smaller so that its total radiative forcing is only about a fourth of that from carbon dioxide. Some other naturally occurring gases contribute very small fractions of the greenhouse effect; one of these, nitrous oxide (N2O), is increasing in concentration owing to human activity such as agriculture. The atmospheric concentrations of CO2 and CH4 have increased by 31% and 149% respectively since the beginning of the industrial revolution in the mid-1700s. These levels are considerably higher than at any time during the last 650,000 years, the period for which reliable data has been extracted from ice cores.[28] From less direct geological evidence it is believed that CO2 values this high were last attained 20 million years ago.[29] Fossil fuel burning has produced approximately three-quarters of the increase in CO2 from human activity over the past 20 years. Most of the rest is due to land-use change, in particular deforestation.[30]



Recent increases in atmospheric carbon dioxide (CO2). The monthly CO2 measurements display small seasonal oscillations in an overall yearly uptrend; each year's maximum is reached during the Northern Hemisphere's late spring, and declines during the Northern Hemisphere growing season as plants remove some CO2 from the atmosphere.The present atmospheric concentration of CO2 is about 385 parts per million (ppm) by volume.[31] Future CO2 levels are expected to rise due to ongoing burning of fossil fuels and land-use change. The rate of rise will depend on uncertain economic, sociological, technological, and natural developments, but may be ultimately limited by the availability of fossil fuels. The IPCC Special Report on Emissions Scenarios gives a wide range of future CO2 scenarios, ranging from 541 to 970 ppm by the year 2100.[32] Fossil fuel reserves are sufficient to reach this level and continue emissions past 2100, if coal, tar sands or methane clathrates are extensively used.[33] Research by NASA climate scientist James Hansen indicates the 0.75° rise in average global temperatures over the last 100 years has been driven mainly by greenhouse gases other than carbon diox

Answer 14

Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing, mostly caused by water vapor.

Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global warming.

It won't be a Hollywood movie style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.

Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.

Answer 15

Most of the info has been said

But the warming of the planet is natural, scientists have proved this by studying the air bubbles in the ice caps, but they also say we have gone far beyond the natural cycle, and the rate of CO2 being let off into the atmosphere is far greater than it ever has in the past
