can you please give me your opinions about global warming?

Question

my son needs opinions for his homework.

thanks in a vance

advance*!!

Answer 1

Its manufactured scare tactics just like the war on terror. Only an excuse to tax and control us. Global warming is a natural weather phenomena that has been with us since day dot. We are on the cycle for global warming as opposed to ice age.

Answer 2

I am certain the Earth has warmed a little, as it has many times before. I'm also certain man is responsible for a small amount of the warming. The burning of carbon based fuels alone causes direct heating of the atmosphere and the small amount of CO2 that man is responsible for as well as the naturally occurring, causes heat to scatter in the atmosphere there by slowing, but not preventing its escape out into space.

CO2 is a naturally occurring gas. It has one carbon atom and two oxygen atoms. Molecules that have three or more atoms absorb heat and re-emit it in all directions. Water vapor also has three atoms. Water vapor accounts for about 70% of the greenhouse effect depending on how much there is in the clear atmosphere and in the clouds.

There are a number of studies that show cloud cover varies inversely with solar activity. The sun has been more active in the past 7 decades than it has been in the last 8000 years and more of the sun's heat is warming the oceans due to decreased cloud cover. A warming Earth causes evaporation and greatly increases water vapor. The ocean currents move the heat all over the world and can take decades to cool, through the process of evaporation.

NASA's solar scientists are predicting a weakening of solar activity and I believe the climate will respond by cooling if that happens.

Answer 3

There is the usual mis-information pretending to be useful answers to this question. For example, the so-called "Dr Jello" provides a link to NASA data claiming this shows the earth was cooling. Funny how NASA themselves have not made this statement, you'd think they'd spot it. In fact the data does not show global temerature, but U.S., and shows the average temperature was HIGHER than the long term average (usually average temp over 30 years or so) for the years 1997 - 2007, as shown by a positive number in the temperature anomaly (the anomaly is the difference between the measured temp and the long-term average).

I wish I had time to answer fully, but since I have answered similar questions many times before maybe you could check them out for scientific opinions on climate change. But the bottom line is the greenhouse effect - increase the greenhouse gases and you will increase the temperature - there is no arguing with the laws of physics.

Answer 4

The Climate has always changed over thousand of years, we are now speeding up the process due to modern technology, When you think of all the changes in just the last 250 years with the industrial revolution and the invention of electricity, sourcing gas supplies, railroads, telecommunications. The cutting down rain forests and and worst of all oil which is used in cars, lorries and the increased aviation use with people flying on several holidays a year, expanding regional airports. Nuclear energy is another problem which we are inflicting on the earths population and the disposal of the waste.

We should we trying to find a cleaner mode of transport, I am sure research is being stop by the greedy oil companies. I won't even start on GM crops which another modern mess.

Answer 5

The current phase of global warming is not part of any 'natural cycle'. We are pumping carbon into the atmosphere at a far higher rate than any 'natural' cycle. What should be understood is that the burning of fossil fuels entails digging up carbon sources that took hundreds of millions of years to lay down, and pumping them into the atmosphere in a tiny fraction of that time, well over ten thousand times the rate it took to set down. The increase in concentration of atmospheric carbon dioxide throughout the industrial age is measurable.

Despite the unscientific protestations of deniers and conspiracy theorists and petrochemical industry pundits, it's happening, it's anthropogenic, and it's serious, however unpopular it may be to say so.

Answer 6

It is no longer proper to call it global warming. People take it the wrong way. Scientists call it "global climate change" now. The weather in your area may not be necessarily warming but it is changing. We don't need to argue wether this is a scam or not. The fact is our climate is changing, man made or not. I personally believe it is due to excess greenhouse gases along with the natural warming process.

Answer 7

I THINK IT IS A NORMAL PART OF THE EARTHS CYCLE OF EXISTENCE.It has happened many times in the past and has been gradually developing in our present phase.You only have to look at the relics of past civilisations that are now beneath the seas or oceans,all of a sudden mankind notices it and suddenly--its chickin lickin ,the sky is falling!!! There are many cities ,villages and other various solids that are now submerged due to rising sea levels caused by melting ice fields.The next race of mankind will be genetically altered to live under water,it is theoretically possible now,and i should,nt wonder if experimental research is forging ahead in this direction.

Answer 8

Action is needed to combat global warming because it is happening and it is accelerating because of CO2 emissions caused by man's activities. It will not lead to the end of the world, nor even the end of life on earth. The world is too resilient for that but, unless we act, it will impact very badly on some species of life including man.

Many species will survive by migrating to areas that suit them better but the pace of change is too rapid for some species of plants and animals, not least because roads and towns stand in the way of migration.

Other species will adapt but their populations will decline hugely before this happens. Man may be one such species.

My main worry is that the pace of change may be so rapid that it will provide a very unpleasant experience whilst going on. As sea levels rise, storms and floods become more devastating and deserts spread, many poor people will die and huge migrations will occur to the developed areas of the world. Conflicts over resources of fuel and water will become more frequent.

It seems likely that at the same time as the climate is responding with such devastation to our CO2 emissions the non-renewable resources (oil, gas and coal) that have fuelled those emissions will be running short and becoming hugely more expensive. This in turn is likely to cause social and economic upheaval on a massive scale. Not the sort of world I want to leave to my children and future generations.

So where is the good news? Well it is not too late to do something about it and the solution is fun. We need to use our intelligence and our technologies to simplify our lifestyles and reduce our use of non-renewable resources (particularly fossil fuels and metals like copper). And the worst use for the non-renewables is to burn them as fuel because of the CO2 this gives out. Oil, gas and coal have much better uses as raw materials that go to make goods ranging from clothes to computers but these uses too need to be reduced so as to make the resources last longer. Wind, wave, tides, hydro and solar sources of power must be used to provide our energy requirements but those requirements must be curbed too. Solving the technological problems of harnessing these energy sources will provide exciting challenges. So will the problems of providing food and other essentials locally so as to reduce transport requirements.

The fact that governments of the world have appointed the Intergovernmental Panel on Climate Change to report on the issues and recommend solutions is really good news. It shows that whilst governments are afraid to tell us the truth themselves they are keen that the experts should, so that we can demand more sensible policies from our politicians (no new runways).

I have found that simplifying my lifestyle has been fun and has made me much healthier and more active. I sold my car and travel by public transport and even more by pedal bike. This has meant an end to money worries and has meant that I can now dance twice as hard and twice as long as most people half my age. By buying less stuff I have reduced my impact on the environment and the pressure to keep up with the neighbours. Switching off equipment when not in use, using low energy lights, turning down the central heating and recycling have become natural to me and cost me nothing.

Best of all by doing these things I am demonstrating to the politicians that there are votes to be had in sustainable policies, to businesses that the development of green technologies will pay off and to neighbours that a simple life is fun.

Reduce demand for stuff. Repair and Re-use stuff. Recycle what can not be repaired.

Best wishes and have fun

Answer 9

I think this question has been answered a few million times already. Can you ask something more specific?

Never mind - it started out as science and was not widely accepted by the scientific community, but it was a neat way to justify funding by predicting doomsday scenarios that should be researched further. As time went on, it became more and more pollitical. You can't do objective scientific research into climate change any more. The results have to fit peoples agendas.

Answer 10

http://www.lenntech.com/greenhouse-effect/global-warming-overview.htm gives a background as to the alleged causes and effects of global warming. However, attention should be paid to the economic effects of the global warming "scare" and its effect on taxation and economic development. Example, the UK government want to expand Heathrow, result, more aircraft pollution, UK Government response, it can be done by "carbon offsetting". Go figure.
