Help my sister?

Question

My sister think Global warming is going to ahppen, will it or wont it?

Mystery i wanted somethign a 9 year old can read, lmao. Thats way to complex for me and im 17. Thanks anyway, you'll get best answer

Oooops missed that wiki bit parrot, thanks mate,

Answer 1

Oh come on now, you can't give best answer to someone who shamelessly copied from the Wiki. It just isn't good form.

Anyway, if you're looking for info on global warming that a nine year old will understand and, more importantly, pay attention to, I guess the best place to start would be the film 'An Inconvenient Truth' by Al Gore. You can very probably get it from your local video store, or you can buy the book. Either way works.

Answer 2

Answer for a nine year old...

The airf is made up of lots of different gases and some of these gases trap the heat from the sun and stop it from escaping into space. These are the gases that we call Greenhouse Gases.

The more greenhouse gases there are in the air the more heat is trapped and the warmer the world becomes.

A lot of these gases occur naturally but humans are adding to them by burning fossil fuels such as coal, oil and gas. Factories and farming also produce greenhouse gases.

In the last 200 years we have produced far more greenhouse gases than nature can handle and the amount in the air has been increasing which has trapped more heat from the sun and caused the world to warm up.

As the world warms up lots of things happen, the most noticeable effect is that it changes the weather and some places start to receive more rainfall and other receive less rainfall. This can lead to floods and droughts which in turn can lead to famine and disease. Some of the other effects include a slow rising of the sea levels, deserts becoming bigger and some plants and animals dying.

These changes happen very slowly, over many years. Some of the effects have been seen for the last 200 years, some of them are more recent and as the world keeps warming up there will be more and more effects.

A lot of people are worried about this and are trying to prevent it from getting any worse by reducing the amount of energy they use in their homes, offices and cars. Some scientists are looking at ways that the harmful greenhouse gases can be removed from the air.

Global warming has always happened because it occurs naturally but humans have made it happen faster and this has upset the natural way the world works.

Answer 3

Global Warming is already Happening.

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.

Global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.3 ± 0.32 °F) during the past century. 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] which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes have probably had a small warming effect from pre-industrial times to 1950, but a small cooling effect since 1950.[2][3] These basic conclusions have been endorsed by at least 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. The American Association of Petroleum Geologists is the only scientific society that rejects these conclusions.[4][5] A few individual scientists disagree with some of these conclusions as well.[6]

Climate models referenced by the IPCC project that global surface temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100.[1] The range of values reflects the use of differing scenarios of future greenhouse gas emissions and results of models with differences in 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 millennium even if greenhouse gas levels are stabilized. [1] This reflects the large heat capacity of the oceans.

An increase in global temperatures can in turn cause other changes, including sea level rise, and changes in the amount and pattern of precipitation resulting in floods and drought[7]. There may also be changes in the frequency and intensity of extreme weather events, though it is difficult to connect specific events to global warming. Other effects may include changes in agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors.

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

Answer 4

Global warming is already happening because the hole in Ozone is increasing day by day because of pollution. The BIG PROOF of global warming is that the ice of south pole is continuously melting due to high temperature of earth's atmosphere.

Answer 5

It is happening. The question is how severe it will be, and if we can stem the evolution before natural amplifiers takes over bringing us to a new climate al together.

Answer 6

Yes It's already happening and has been for some time.

Answer 7

It will. Here's a website for your sister that explains it:

But we can reduce it enough so that we can deal with it.

Answer 8

.yes its happening. but its natural occurrence. just 30 years ago, everybody thought we were having another ice age. it warms up and cools down.its natural

Answer 9

wow she did write ALOT but all good info. I figure, as long as we aren't doing things that can hurt my dog and my kids, does it matter "why"

Answer 10

it is happening. why do you think people are freaking out about melting glaciers and icecaps, rising water temperatures, and increased heat everywhere?
