Another Study Showing Significant Global Warming

New reports from International Argo Project has shown a significant rise in temperature of ocean. The upper layer of Earth’s ocean has warmed since 1993, indicating a strong climate change signal, according to a new international study co-authored by oceanographer Josh Willis of NASA’s Jet Propulsion Laboratory, Pasadena, Calif. The energy stored is enough to power nearly 500 100-watt light bulbs for each of the roughly 6.7 billion people on the planet continuously over the 16-year study period. A warming ocean is a direct cause of global sea level rise, since seawater expands and takes up more space as it heats up. The scientists say that this expansion accounts for about one-third to one-half of global sea level rise.

The international science team analyzed nine different estimates of heat content in the upper ocean, based on ocean temperature data from a global array of more than 3,200 Argo free-floating profiling floats and longer data records from expendable bathythermographs dropped from ships.

Combining multiple estimates of heat in the upper ocean – from the surface to about 610 meters (2,000 feet) down – the team found a strong multi-year warming trend throughout the world’s ocean. According to measurements by an array of autonomous free-floating ocean floats called Argo, as well as by earlier devices called expendable bathythermographs, or XBTs, that were dropped from ships to obtain temperature data, ocean heat content has increased over the last 16 years. Data from the array of Argo floats — deployed by NOAA and other U.S. and international partners — greatly reduce the uncertainties in estimates of ocean heat content over the past several years, the team said. There are now more than 3,200 Argo floats distributed throughout the world’s ocean sending back information via satellite on temperature, salinity, currents and other ocean properties.

Below is the map shows an estimate of the change in upper Ocean Heat Content Anomaly (OHCA) from 2007 to 2008 derived from both in situ data and altimeter sea surface height mapping performed according toWillis et al. 2004.

Historical data are from XBTs, CTDs, moorings, and other sources.  A preliminary ad-hoc fall rate correction has been applied to the XBT data in an attempt to correct for biases between XBT data and more accurate CTD data.   Additional displays of the upper OHCA and sampling error are available in thePlots section.

Isn’t this enough to prove global warming?

    Sadly the people still in denial about AGW aren’t going to be persuaded by any logic. Until the problem is so bad that governments (read: US government) are willing to take on their oil industry patrons, nothing will get done. And by then it will likely be far to late. Jesus wept.

    Hmmm… I don’t think these political climax will ever be solved. Perhaps this has become trend for political gamers..

    It doesn’t seem probable that doomsday will come through collision of nibiru but it seems me more probable that i may come through global warming.
    I live in a city of RUSSIA. what I can see there is, only unsustainable development and uncontrolled industrialization. It has raised temperature significantly. It enough yet, deforestion causing so many problem like species extinction and problems for native villages. I don’t know when it come to an end?
