OCEAN WARMING DETECTED -  Most of the observed global ocean warming over the past 50 years is attributable to human activities, according to a new study. The study by a team of Lawrence Livermore National Laboratory scientists and international collaborators revealed that the observed ocean warming over the last 50 years is consistent with climate models only if the models include the impacts of observed increases in greenhouse gas during the 20th century. Though the new research is not the first study to identify a human influence on observed ocean warming, it is the first to provide an in-depth examination of how observational and modeling uncertainties impact the conclusion that humans are primarily responsible. 
The group looked at the average temperature (or heat content) in the upper layers of the ocean. The observed global average ocean warming (from the surface to 700 meters) is approximately 0.025 degrees Celsius per decade, or slightly more than 1/10th of a degree Celsius over 50 years.

“We have taken a closer look at factors that influence these results,” said Peter Gleckler, an LLNL climate scientist and lead author of the new study. “The bottom line is that this study substantially strengthens the conclusion that most of the observed global ocean warming over the past 50 years is attributable to human activities,” he added. The sub-surface ocean warming is noticeably less than the observed Earth surface warming. “Although we performed a series of tests to account for the impact of various uncertainties, we found no evidence that simultaneous warming of the upper layers of all seven seas can be explained by natural climate variability alone. 
Humans have played a dominant role,” Gleckler added. In this study the team, including observational experts from the United States, Japan and Australia, examined the causes of ocean warming using improved observational estimates and the effects of the observed increase in greenhouse gases over the 20th century. The finding has recently published in the journal, Nature Climate Change.

Natural fluctuations alone do not explain warming in the upper layers of the planet's oceans, confirms a new computer modeling study. The ingredient necessary to fully account for rising water temperatures in the last 50 years? Humans' greenhouse gas emissions. "We're virtually certain that the oceans have warmed, and that warming is caused not by natural processes, but by rising greenhouse gases primarily," researchers say. The earth caters to everyone's needs, but today we suffer because of our greed for the enjoyment of our senses and for wealth.

We can save the earth from further deterioration only when we can understand the root cause of the present environmental disaster. ... Recently, the United Nations Food and Agriculture Organization issued a report stating that the livestock business generates more greenhouse gas emissions than all forms of transportation combined. The Humane Society of the United States has taken up the issue as well, running ads in environmental magazines that show a car key and a fork. 'Which one of these contributes more to global, warming?' the ads ask. They answer the question with 'It's not the one that starts a car,' and goes on to cite the UN report. 
It is high time to eliminate the four major sins and our unlimited greed to strive for the real aim of gaining transcendental loving devotional service to God in His spiritual abode. God created the earth and God alone can save the earth.
