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)

Answer 2

global warming is from trapped greenhouse gases (cars etc) and they say it is happening because the ice caps in  the north are melting and our temperature on earth as a whole, is getting hotter each year.

Answer 3

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.

The global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 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-20th century is very likely due to the observed increase in anthropogenic 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 30 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 21st 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.

Terminology

The term "global warming" is a specific example of climate change, which can also refer to global cooling. In common usage, the term refers to recent warming and implies a human influence.[11] The United Nations Framework Convention on Climate Change (UNFCCC) uses the term "climate change" for human-caused change, and "climate variability" for other changes.[12] The term "anthropogenic global warming" is sometimes used when focusing on human-induced changes.

Causes



Components of the current radiative forcing as estimated by the IPCC Fourth Assessment Report.Main articles: Attribution of recent climate change and Scientific opinion on climate change

The Earth's climate changes in response to external forcing, including variations in its orbit around the Sun (orbital forcing),[13][14][15] volcanic eruptions,[16] and atmospheric greenhouse gas concentrations. The detailed causes of the recent warming remain an active field of research, but the scientific consensus[17][18] 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 the temperature increase. One such hypothesis proposes that warming may be the result of variations in solar activity.[19][20][21]

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.[22]

Greenhouse gases in the atmosphere

Main articles: Greenhouse gas and Greenhouse effect

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 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.[23][24] Rather, the issue is how the strength of the greenhouse effect changes when human activity increases the atmospheric concentrations of some greenhouse gases.

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%.[25][26] 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. From less direct geological evidence it is believed that CO2 values this high were last attained 20 million years ago.[27] Fossil fuel burning has produced about 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.[28]



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.[29] 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.[30] Fossil fuel reserves are sufficient to reach this level and continue emissions past 2100, if coal, tar sands or methane clathrates are extensively used.[31]

Feedbacks

Main article: Effects of global warming#Positive feedback effects

The effects of forcing agents on the climate are complicated by various feedback processes.

One of the most pronounced feedback effects relates to the evaporation of water. Warming by the addition of long-lived greenhouse gases such as CO2 will cause more water to be evaporated into the atmosphere. Since water vapor itself acts as a greenhouse gas, the atmosphere warms further; this warming causes more water vapor to be evaporated, and so on until a new dynamic equilibrium concentration of water vapor is reached with a much larger greenhouse effect than that due to CO2 alone. Although this feedback process causes an increase in the absolute moisture content of the air, the relative humidity stays nearly constant or even decreases slightly because the air is warmer.[32] This feedback effect can only be reversed slowly as CO2 has a long average atmospheric lifetime.

Feedback effects due to clouds are an area of ongoing research. Seen from below, clouds emit infrared radiation back to the surface, and so exert a warming effect; seen from above, clouds reflect sunlight and emit infrared radiation to space, and so exert a cooling effect. Whether the net effect is warming or cooling depends on details such as the type and altitude of the cloud. These details are difficult to represent in climate models, in part because clouds are much smaller than the spacing between points on the computational grids of climate models. Nevertheless, cloud feedback is second only to water vapor feedback and is positive in all the models that were used in the IPCC Fourth Assessment Report.[32]

A subtler feedback process relates to changes in the lapse rate as the atmosphere warms. The atmosphere's temperature decreases with height in the troposphere. Since emission of infrared radiation varies with the fourth power of temperature, longwave radiation emitted from the upper atmosphere is less than that emitted from the lower atmosphere. Most of the radiation emitted from the upper atmosphere escapes to space, while most of the radiation emitted from the lower atmosphere is re-absorbed by the surface or the atmosphere. Thus, the strength of the greenhouse effect depends on the atmosphere's rate of temperature decrease with height: if the rate of temperature decrease is grea

Answer 4

its us that are making it happen.... gasoline... but also many other things...... but the icebergs always melt a little bit in the summer..... its like O MY GOD..... THE ROOSTER WENT PEE.... IT MUST BE GLOBAL WARMING!!!!!!! ANYTHING THAT HaPPENS IS BLAMED FOR GLOBAL WARMING! they say were all gonna die.... but the said 20 years ago we were all gonna die because of GLOBAL COOLING...... are we dead....? NO!!!!!!!! so... it may be happening... slowly... but on the news they show the same polar bear and the same iceberg... tell me if u ever see a new one please!....... but other wise it's just people who think its happening are the ones who are making it happen (ALGORE)!

Answer 5

More greenhouse gases are being produced and causing the heat to be trapped or destorying the ozone layers to allow harmful Sun rays to enter the Earth. This will mean more cancer, more disappearance of speices due to changing ecosystem (ex. global temperature) and massive flooding due to the extra volume of water melted from ice found in cold regions, such as Arctic and Antarctica..

Answer 6

As the Earth gets warmer , the Sea gets  higher. and at the end of the day  7 billion people will have to stand on the highest mountain,or learn to live in the Sea.  ok.

Answer 7

Global Warming is a SCAM.

Answer 8

Global warming is caused by pollusion which comes from gas emeissions from cars, factories, and other enviornmental pollutents. The gass emissions are trapped within the atmosphere and then cause a green house effect which is the rise in temperatures caused by the trapped gasses. Chemicals in the air can be harmful for us, plants, animals and other natural forms. Global warming is causing the melting of ice caps in places such as Greenland and the Arctic. Some sciences say in another 12 years we will expect a rise in sea levels of about 7 meters. The rise in sea levels can cause some cities such as new york to be under water because these cities lye below sea level. Cities on higher elevations are less likely to be as effected by the sea level rises. Temperatures will also increase over the years and enviornmental pollutants may cause sicknesses in people such as asmtha which is already proven to be causing these illnesses. If you want to live in a cleaner world the start recycling and carpooling much more. Recycle things like paper and plastics. Carpooling is to travel in a car at the same time with a larger amount of people to save the amount of car trips in the future this can prevent some pollusion.

Answer 9

Global warming is happening because of trapped greenhouse gases (smoke from cars, factories, etc.)caught in the atmosphere

The temperature rising makes storms/hurricanes bigger and stronger. Disease thrives on warm weather. The melting of permafrost peat bogs releases methane into the air. It's predicted that each 1% increase in annual precipitation would enlarge the cost of catastrophic storms by 2.8%. As you probably saw in the news last summer, there will be lots of forest fires.Increased extreme weather means more water falls on hardened ground unable to absorb it, leading to flash floods instead of a replenishment of soil moisture or groundwater levels.
