Excess carbon dioxide is accelerating global warming, sea level rise, ocean acidification and overall climate change.

This design explores the possibility of living on the oil rig, above and below the ocean level.
FORBES: Audacious New Concept Turns Oil Rigs Into Luxury Homes
Oceans Day at Durban will draw high-level attention to ocean issues during the COP17 climate talks, highlighting the direct link between climate change, the health of the oceans, and human well-being, as well as the need for sufficient funding to support bold mitigation and adaptation measures that will minimize climate change impacts on coastal communities and ocean ecosystems and resources.
The key was not to try to dig a Suez-type of canal, a great sea-level trench from ocean to ocean, but to create a lock-and-lake canal, where the ships are lifted up by a series of locks to a man-made lake, and then they sail across that lake, and then they are set back down on the other side by another series of locks.
In addition, he says, investment is needed in research and development to take the industry to the next level to build bigger ocean-going vessels.
He therefore gave his models a series of decade-long tests beginning with the real climatic conditions (level of solar radiation, ocean temperature and so on) on 80 different start dates from 1982 to 2001.

The Deputy Committee is charged with executing the National Ocean Policy objectives and includes 25 senior-level officials from Federal agencies, departments, and White House Offices identified in the Final Recommendations of the Ocean Policy Task Force.

The total catch of the toothfish, known as the "white gold" of the Southern Ocean, is double the level believed previously.
Many factors must be considered to understand how shifts at the individual or species level might ripple through an entire ecosystem and affect ocean services and resources.
For every two gallons of water the plant takes in, its reverse osmosis process will make one gallon of fresh water and send back to the ocean one gallon with twice the salinity level.
The room sits on the bottom of a three-level floating structure, located 250m from shore in the Indian Ocean.
Once ice is discharged from a grounded ice sheet into the ocean, it has an immediate impact on sea level, even though it remains part of the cryosphere until it subsequently melts.

For example, as the atmospheric carbon-dioxide level in Hawaii goes up, the pH at a mid-ocean mooring about 450km to the north-west goes down (see chart).
Disaster mitigation, through early tsunami warning systems, but also by quantifying the trends of typical marine hazards, including typhoons and storm surges, sea level rise, or harmful algal blooms, are critical objectives of ocean monitoring with immediate and sustainable impacts.
"If you extrapolate these results, Greenland is going to be a serious contributor to global sea-level rise" in coming years, said Peter Wadhams, a professor of ocean physics at the University of Cambridge, England, who wasn't involved in the Science study.
However, the fact that more ice rests below sea level means that on millennial timescales, increased amounts of ice are potentially vulnerable to ocean melting.
Now on the scale of the next century, the projections are suggesting that, between the ice and thermal expansion of the ocean, that we're likely to see upwards of a meter of sea level rise.
People don't easily understand how a small sea level rise can result in bigger storm surges and coastal damage, or how slight changes in ocean temperatures can change global rainfall patterns, leading to droughts and floods with catastrophic economic and societal consequences.
Coordinated internationally by the Ocean Conservancy, the activity of cleaning up beaches and waterways takes place on an international level.
Geologic history shows that over a LONG time period that sea level changes by about 65 feet (20 m) for each degree C of change in the ocean.
FORBES: Why Most Forbes Readers Know More About Global Warming than Most Climate Scientists
Since independence in 1976, per capita output in this Indian Ocean archipelago has expanded to roughly seven times the pre-independence, near-subsistence level, moving the island into the upper-middle income group of countries.
Storm surges have the potential to be dangerous because they involve a great upwelling of a stretch of ocean - intense low pressure at the heart of a storm literally tugs the sea surface above its normal level to create a massive bulge.
