what is global warming? what are the effects and available solutions for this?

Answer 1

global warming is when the ice caps are starting to melt at both caps as well as too much polution going on. it happens when countries like the US does not preserve its many natural resources, does not recycle, has too many cars and too much pollution which leads to holes in the ozone layer, temperatures in different countries where it is not that warm to sky rocket, tornadoes to happen, and so forth. for example i am from Romania and I have seen a ton of flooding, the temperatures over there being 100 F degrees, and tornadoes happening .the solutions are various: one of them was for the US as well as many other countries to sign a treaty or pact about global warming except that the US did not since the signature would have costed the US a lot of jobs, since the treaty tells the US to lower the pollution and exhaust amount, to preserve things, to recycle more, and to overall use less of everything. we, the US are probably the biggest consumer when it comes to cars, etc. yet we also are the biggest pollutant country. the solution is to use cars like hybrids, have less cars per family, to watch how we consume the energy and so forth. i guess i got my point across.

Answer 2

Global warming is caused by a massive increase in carbon emissions into the atmposhere, caused by man.

The Al Gore film "An inconvenient truth" covers this in great depth.

As a society there is much we can do to help save the environment for example, reducing the number of aircraft flying around the world, using less electricity etc etc.

Answer 3

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 has risen 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 first speculation that a greenhouse effect might occur was by the Swedish chemist Svante Arrhenius in 1897, although it did not become a topic of popular debate until some 90 years later. [2]

The measure of the response to increased GHGs, and other anthropogenic and natural climate forcings, is climate sensitivity. It is found by observational [3] 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 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. Other consequences include higher or lower agricultural yields, glacial 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 an estimated atmospheric lifetime of 50 to 200 years. [4]. 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 4

We must elect Al Gore before the Planet is doomed. It does not matter that China, India, Indonesia, South Asia, Russia, Poland, Turkey, Iran, Syria and others I don't have time to mention...create 80% of pollution in the world. Al Gore might be able to pronounce a global Jihad on them after he destroys our economy at home. Only then will we be safe from Rush Limbaugh and Fox News.

Answer 5

global warming is just another band wagon the labour government has jumped on to tax us to the hilt.

Think on this ... the 2 most important issues of the day are refuse and global warming. If we land filled to 20 foot (old money hear none of your european union bull@@it)all the refuse we could manage then the rising tides of global warming would mean nothing.

Answer 6

A nice easy way to cut down on your Gas and Electric Bills.

Answer 7

too much carbon dioxide in the atmosphere, solution reduce cars by 50%

Answer 8

global warming is bad the effects are bad it is bad but we will be ok i hope

Answer 9

wouldent worry about it.. let next generations worry. you and i will be fossilised anyway..have a good life..?

DO'NT ASK THE YANK'S , THEY DO'NT WANT TO KNOW
