He is not responsible adversely but many positive contributions have been made "beyond" sustainable initiatives through Traditional Knowledge systems. Please get back to basics and native villages for relearning such wonderful time tested initiatives.i have such compilations for Andhra pradesh.Any one else pl respond.

I partially agree with VB, but we presume that a theatre can accommodate 500 persons, by adjusting 250 more can be accommodated for 3 hrs show. The initial room temperature is 28 degree C, and the temperature tend to increase gradually due to CO2 released by inmates, on the contrary if 50% start smoking the temperature would increased dramatically. similar is the case with population more demand more burning of fossil fuel, for transport,electricity,water other products etc. Of course many positive contributions are made. By proper Environmental Management approaches the problems can be mitigated or slow down.

I am agree with your comment. Man has to think about environmental protection and it conservation. we have to stop indiscriminate use of fossil fuels and other natural resources.

From my perspective, should we claim that we have made a lot of profitable contributions to every kinds of life in this world if it is ourself human who cause adverse impacts on earth nowadays. Moreover, without human existence, other lifes can live thier lifes in this world.

"yes, u r right. men is most responsible for climate change. this pasted climate change caused by man is called as climate catastrophe."

Not true. Have a look at the NOAA Ice-Core graphs on,

http://WattsUpWithThat.com/2009/12/09/hockey-stick-observed-in-noaa-ice-core-data/

For a 400,000 year view of Temperatures and CO2 levels, try Googling 'vostok ice core data' also on an NOAA site.

There are two huge Worldwide Problems.

(1) Overpopulation.

There is no easy solution to the problem. Mankind naturally procreates - it's built into our genes - and we are living longer and who can decide where the growth is going to be limited other than by global catastophies, disease, wars, food shortages, fuel shortages, and ice ages.

(2) Exhaustion of Fossil Fuels.

This will contribute in part to the solution of (1) above.

We have used roughly 50 percent of the worlds Fossil Fuels in the last hundred years and the rate of consumption is growing more or less linearly.

It took 92 Million years to lay down the oil and coal deposits and we have used approximately half of it in the last 90 years. If the growth in consumption continued to grow at the present

rate then it would last for only 30 years. Some of us alive now will be still around when it happens.

Yes you are right , but the scientific community and business cannot act quickly enough by it self despite the huge investments and the outcomes are not certain, so we must transform the way we use natural resources by reforming the tax systems so a tax on natural resources will replace all existing taxes!

Yes I am agree with your view. becase there is indisciminate use of natural resources and people thinks it is for man king only.

Some facts need to be explained before believing in any statement. For instance, all climate changes, some drastically, some recently, before man on Earth or before the last 100-150 years have to be clearly explained and are not due the Humans. We don't know everything, we can't do everything, we can participate. We have to take care on correlations. If you want, or you want to see, almost everything can be correlated. The main feature of the science is that everything can be contested, including our solid beliefs. Climate change is now a hot issue. Some people are getting a ride on in this boat, some people are taking a ride on this boat (that can sink or sail to a safe harbor).

I am fully agree to your statement. but the question is man is the latest animal in the entire race of animals with the most evolved brain. For a while forget about natural calamites becas we do not have control on it. Many natural things man can not predict or stop, it happens naturally and nature can adapt it self. Issue is man wanted to take the charge of every thing including natural things, natual resources for his progress he never thought of the nature and environment till today. Hence i think human beings are the most dangerous animal in our planet who produce the maximum harm than any other organisms. (Forget natural calamites as we do not have control on it)

Man is the major actor in many enviromental changes. No doubt. Some irreversible. I would like to see people not only looking into a set of statistical data, but trying to see more than correlations. Why we are living more than a hundred years ago? We could see a strong correlation with the slope of medicines development, the most accepted theory, but we can also consider the availability of foods, no stress to find food, no more working 20 hours a day, better clothes, and so on. I like statistics. I also like to see two or more correlated factors. It is great! Global warming is real, but for me is difficult to believe in only one factor. This discussion has being the same for a long time. People are repeating the same verse because the rythm looks like good. I feel that there were no new ideas in the last 20-30 years. Too many time for our scientists.

This discussion has being the same for a long time but as you told no new ideas i the last 20-30 years. Day by day the situation become worst. and entire ecosystem on the earth will be collapse. Hence every scientist , every conman man should think about nature in which we are living. At least some contribution should be given. so that not only human being but all living organisms live happily, and with harmony on this mother planet.

There has been no real change in the last 20-30 years due to all governments do not want to address the fundamental problem of taxing the wrong things.

Tax on money, inderviduals, businesses will only maintain the existing status-quot ,Taxes need to be reformed to tax all natural resources based on their environmental impact. and remove all existing taxes.

In other words tax environmental damage what ever source it is derived from

It is through these financial instruments that speedy change could and should occur to help in a more equal and just society.

note:

Natural resources include all fossil fuels , minerals , and land itself .

I never told that Humans aren't changing the enviroment. Here in Brazil, it's obvious wherever you are. I know, I see, I feel. The main idea of what I'm writing is: we have to explain many things before saying that the climate change now in progress (if so) is due only to human activities. As I mentioned before, we have to explain the reason of all changes occured in the past (far and near). If I'm not wrong, in the 1800's there was a little, little ice age. Why? And I'm not saying about 1815-1816. There are and there are not some "drifts" in the CO2 (IPCC) curve if we take a closely look in the past 100 years. I think that these "events" must appear in this curve and they aren't or they are there. I'm trying to see this issue as much as possible with a logical view. I'm trying to apply the most fundamental point of science, that is, every thing or any idea can be contested, nothing is entirely right. I'm not skeptical. If we take a look of what is happening in the Physics, the light speed in vaccum is not the ultimate speed anymore. Unless it was changed again. I'm happy with this discussion.

I am very happy that many people taking interest in the field of environmental issues after all we I mean all human race want to live in hormony and our planet gives all that is required for the life. We do not have control on the natural calamites as you suggests. But becase of man kind the problem sholud not increase more. now a day becase of man many types of pollution has been increased like air pollution, water pollution , noise pollution, land pollution and more important social pollution. No other animals or organisms produce such type of problems even they are living since ages. man has to learn lessons that how other organisms plants animals living in nature without disterbing the nature. only human being is responsible for the pollution problem which is the mainh cause of climate change. Thanks

true, human activities have contributed to high global warming, depletion of the ozone layer and a greater increase in dangerous gases like CO, NO, SO2 to mention but a few...........we are slowly destroying our habitat!

If we muse on the climate before man was here, we will know what else can change climate.

Anyone knows the consequences of global warming on CO2 solubility in ocean water? I think if the rise of atmonspheric CO2 concentration is due to global warming or global warming is inducing the rising of atmospheric CO2. Can anyone tell me if there is a paper or report with this issue?

Have a look on paleobotany and climatology. You will get the answer taht how animals and plants and our nature was in those days. And compare the climate change with and without man. You will get all the answers.

Thanks
