The climate of the earth has undenying gone under several climate change cycles. What concerns us is the rate and intensity with which the earth climate is changing now. The changing climate has several associated risks to various ecosystem and human being an integral part of the system is ultimately going to be affected.

You can further read IPCC report(s) to judge why this change is different from the ones that did took before.

It's important to know the cause?

We surely want to know, how much we are part of the cause, to eventually control the effect. My personal observation is that the 'traditional' directions of wind have changed, e.g. strong Atlantic influence in the Alps. This might be connected to emissions and contaminations of increasing human energy consumption, but it is difficult to prove scientifically and methodically.

I do agree with Arben J Salihu

If human activity is adversely impacting, we need to work to address it as it is reversible.

Respected Sir@ Dr latief Ahmad

It is evidenced that climate change has adverse effect on earth and we really need to go for sustainable approaches to contribute for its limitations. Though our contribution is very less with respect to industry and other commercial practices but our small initiatives will defiantly bring some positive change as a whole.

yes in past it might have been repeated many times but it was in same pace of human population as natural balance was there like natural calamities, risk to survival of all the young ones, war, and many more with lower human population density on the earth. hence all the natural processes were going in sustainable manner. now the things has been changed and human population density increasing by many folds with the requirement of high level of comfort at the cost of natural resources especially non-renewable resources. therefore, a stress/influencing factor with increasing rate by leaps and bounce are being imposing on the natural habitats of all living beings on the earth. hence a mitigation approach is desired towards changing climate.

The advent of human civilization has developed largely in greenhouse gas at 180 to 280 ppm carbon dioxide but since the advent of massive use of fossil fuel the carbon dioxide has reached over 400 ppm which has not been experienced in over 1,000,000 years. At current rates this could double again in the next 100 years creating a potential for a much hotter environment. The increase of this greenhouse gas has been at unprecedented in its rapid rate also related to human combustion in the fossil fuel economy. With very rapid changes the biological diversity of our living planet can be drastically reduced. . This suggests that our current climate changes are not being governed by the natural cycle may need to be adjusted down to the natural cycle levels. In the hyper greenhouse gas environments all massive extinction events have occurred. The moderating of these Greenhouse levels should moderate the extent and of the global warming and accelerate a return to a more natural cycle. Issues which can be helped is the damages from rising sea levels the damages of violent weather events which can negatively influence food production and plant and human health. The use of fossil fuels are a non renewable resource and the transition to a different energy mix along with sequestration strategies will allow a recovery of our environment and allow our economy to be based on sustainable resources rather than nonrenewable ones. Rapid advancements of conservation efficiency and in alternative renewable energy resources will make this advantageous in may ways including the reduction in health reduced contamination of soil water and air.

What is so alarming is the intensity and rate of change in the climate.

• Not only does the tendency of fossil fuel emissions show concordance with fossil fuel as the source of increasing atmospheric greenhouse gases but also the isotopic signature of the carbon increase in the atmosphere is showing an ancient fossil fuel signature rather that current source signature that and the lack of an ability to show significance of alternative explanations such as vulcanism and solar variation give a pretty good indication that fossil fuel is it.

We have to control/stabilize global climate change because the concentration of carbon gases (e.g.: CO, CO2, CH4) that we spew into the atmosphere are increasing rapidly as Dr. Hepperly wrote. The consequences have become part of the news of the day in every world country and often, with devastating effects, landscapes are for ever changed. These drastic changes (e.g.: floods, droughts, forest fires, extreme snow precipitations, polar vortices, etc.) are destroying livelihoods, homes, increasing loss of human life and misery. Crop losses are affecting food security and economies world wide. The ramifications of global climate change are many, eventually accelerating the path leading to mass extinction. This is why we must try to avert, reverse global climate change.

Earth will go same way as we are not interfearing. But we are not allowing it to do. so directly or indirectly human activities are responsible

Thank you all

Climate changed in the past by the forces which prevailed during that time. We have no evidence that a single plant or animal species was found responsible for a major change in the climatic pattern in the past. But, what is happening today is mainly the result of the actions of a single species i.e. Human and more worrying is the fact that this all happened in a time scale of 200-300 years. Moreover, as the most advanced species, we have an ability to observe over surroundings and measure the extent of changes happening around us. All of these factors makes this present climate change phenomenon a peculiar one.

The other side of coin is that the Human is also a part of the nature. So, the actions of human can be taken as a natural and simple phenomenon of change. No one is there to judge us except us.

Because mankind has 'dis-stabilized' the natural equilibrium of self-sustaining ability of the natural environment. This is the consequences of greed in the name of development.

Drlatief Ahmad. in past condition, the intensity and severity of the climatic events are slower rate and its potential to harm the natural biota is slower but now a days its magnitude of climatic events is increased day by day and it solely responsible by industrialization, automobile exhaust, intensive cultivation and human intensification. As per IPCC reports, in end of the 19th century will emerge out as a changing climatic events like heavy rainfall, hailstroms, duration and intensity of rainfall, drought and flood. Such type of climatic extremes are prone to developing countries which is situated near the coastal region. The first report of climate change was given by IPCC in 1990 in First assessement report after that it was confirmed in 2007 by his Fourth assessement report (It tells increased in temperature about 0.74 C from its normal).

In the last 100 so years of intensive industrialization the temperature of the globe has increased a little over 1 degree centrigade and the ocean level less than 1 foot. As polar masses and glaciers melt the scientists predict the complete effect would be to increase seal level 215 foot about 70 meters which would result in about 20% flooding of global coastal areas. Since the bulk of world population is located along coasts this will result in massive change for future generations. The result of man activity is also degrading the ocean and water systems we need for our future sustainability and health. Working to moderate this dramatic effects and to adapt to them is a fundamental issue for the human population
