“Only we humans make such waste that nature can’t digest. I hope for your help to explore and protect the oceans from waste, that will restore its health. Health means to oceans is the health for us. “No water, no life”.
Oceans plays significant role in our climatic systems, by generating oxygen and absorbing the carbon dioxide from the atmosphere. They also provide us services for the sustaining the life on earth. If changes occur in our climatic system, it increases the levels of greenhouse gases in the atmosphere that will leads to the change in oceans by;
 Increasing the sea-level.
 Oceanic acidification.
 Putting marine ecosystem and coastal communities at risk.
 Causing vulnerability of food production.
Climate change bring concerns about food security and causing vulnerability of marine fishes. According to recent studies it indicates that impact on climate change will exceeds from its projection level set by IPCC in its fourth assessment report, 2007. Climate indicates like sealevel rising, global ocean temperature artic sea-ice melting beyond the patterns of natural variability in which contemporary society and economy have developed & thrived.
According to recent studies the past decades has been the warmest on the record and warmer climate contribute in rising sea level and artic oceans has to be continued to decreased and 2009 was marked as third smallest area of sea level rising. The sea level rising for Pakistan estimated at 1.1mm/year from 1856-2000, sea level rose at 0.19meter over the period 1901-2010. The rate of change was markedly higher during later periods. Global average sea-level was 1.4mm/year between1993-2010. Major reason of sea level rising is thermal expansion of oceans from global warming and glacier mass loss.
Mitigation and Adaptation:
There is need to do efforts at various levels to mitigate the impacts of climate change in context of ocean related activities. Through these efforts reduced the greenhouse gases emissions, also mitigate the impact of climate change including carbon sequestration and ocean fertilizers. More generally adaptation strategies will need to improve the sharing of scientific information and knowledge on climate change increases capacity building and transfer advanced technology to developing ones. Reducing vulnerability of coastal communities more generally
will enhance their ability to adapt range of stress, including climate change and extreme weather changes. At international level there is need to address this topic more firmly and positioned in the border of sustainable development and actions on climate change will need to be integrate into borders development efforts and scientific research.
“We know that when we protect our oceans we’re protecting our future” “no blue, no green, no life”.
