What is Climate change: Ecosystem in the planed is not continued if energy is not coming continuously from the sun. Only part of the energy coming from sun in terms of radiations is retained by the earth in its atmosphere. Rate of energy retained by the earth depends on the amount of the green house gases in its atmosphere. This is the energy which global ecosystem and makes earth planed living. In case more or less energy is retained due to changes in amount of GHG then ecosystem also changes and as a result some or more elements in the system including human being may feel convenient or inconvenient than before and need to transform them self to adopt new system. This is called climate change which becomes force to ecosystem change. Main indicator in the climate change is global warming or global cooling. Present trend is global warming. Climate change is contributed at local level realized at local level differently based on local ecological system but calculated at global level. Means to say is that climate change at local level is not the result of emission contribution at local level. Everything goes to global account and effect goes to different places differently. This demands global action for climate change.

Adaptation: People says this is the longest drought after so many years, Highest rainfall or flood in so many years, highest temperature in so many years. These entire event are not climate change. It is just a cycle that repeats. For climate change there has to be shift in climate permanently. It is determined by at least 30 years of data. If more energy has been retained for longer term there will be certainly climate change and ecosystem change in line with energy. How it is felt in the environment is different thing. It is not easy to predict and say climate change distinctly and differentiate from local environmental changes because it makes confusion as it combines with climate cycle.

Actually climate change automatically transform ecosystem and force each element to change. In large change it may remove some species and create new one. If human being is going to be one removed it is dangerous. In the ecosystem it is not possible to save human being without caring other elements. That demands for action to care or love nature. Hence, principally there is no adaptation for climate change. To become concision on effect on climate on life support system and plan for development activities in consideration may help temporarily. But i the long term climate change adaptation is meaningless. There has been lot of works on climate change adaptation. For poor people it does not matter how fund comes. What they need is development. For example: If people do not have safe and reliable water system yet there is need for development for water supply system. It can be a development project by water supply sector as a part of reaching to unreached, it can be from poverty alleviation sector, it can be environment improvement sector or it can be from climate change adaptation sector. Donors seek the channel where their money gets more value or popularized. Adding funds on development in the name of adaptation does not really help adopt climate change. If there reductions in rain fall in catchment area by climate change it will reduce availability of water for the people. If this due t local environmental changes it are different cases. Understanding of climate change effect or non climate effect will have different solution. Understanding may help designing development of water supply system. Putting money for development cannot be the adaptation.

Mitigation: People cannot mitigate effect of climate change in their locality directly. It is global action. Action is actually taken at local level but need to be done global means by all. There is somehow problem here because an effect is not direct. Every one collectively can help everyone. For mitigation people need to change their habit and reduce carbon foot print. Development technology and criteria need to be changes. All policy and guideline has to be reviewed and change. For example: Feasible water supply system now is one which needs minimum investment. But if we see from climate change prospective we have to see which option have more potentiality for carbon emission. We have to chose gravity flow system than pumping system because it needs no or low energy. We need to encourage preventive system for water safety than treatment by boiling. We need to use solar heating system for warm water. Similarly onsite pit latrine is best for sanitation. If we see from climate change point of view aerobic treatment system is better, oxidation pond is even better and anaerobic treatment system with methane burning is even better and connection to bio-gas plant is far better.

Global actions: To leave sustain ecosystem and our generation longer with same comfort it is necessary to take global action. For this there is need of some kind of global governance. Present political system needs some changes or transformation. Coordination and collaboration also works but less chance to be effective. Every country should have dedicated ministry for environment and climate change. Every ministry in the countries should have climate change unit to work in coordination with climate change ministry. Focal unit need to review all their activities in line with climate change. They need to recommend for changes required if there is chance to reduce carbon emission. Inefficient actions without coordination should be avoided. People and agencies are making big noise on climate change out far from mike. What we need to do is make a efficient system globally. There is need of local, national, regional and international research and information center for climate change and mitigation ways not adaptation.
