  4. The heat has gone into the ocean. It may be a mystery to NASA but it not to NOAA. There is new data that has just come out. See DB's article.

    What the fuck is wrong with you? Reboot or something.

    The stupid is strong with this one.

    The NASA press release came out on the 6th.

  6. The abyss is the very deep part. The upper level is where the heat went. Why you are having so much problem with such a simple concept I do not know. Note, in the chart above how the rate of heat increase increased around 98. There also may have been less heat due to aerosols reflecting the sun.

    Independent research in Israel and the Netherlands in the late 1980s showed an apparent reduction in the amount of sunlight,[13] despite widespread evidence that the climate was becoming hotter. The rate of dimming varies around the world but is on average estimated at around 2–3% per decade. The trend reversed in the early 1990s. [1] It is difficult to make a precise measurement, due to the difficulty in accurately calibrating the instruments used, and the problem of spatial coverage. Nonetheless, the effect is almost certainly present.

    The effect (2–3%, as above) is due to changes within the Earth's atmosphere; the value of the solar radiation at the top of the atmosphere has not changed by more than a fraction of this amount.[14]

    Smog, seen here at the Golden Gate Bridge, is a likely contributor to global dimming.
    The effect varies greatly over the planet, but estimates of the terrestrial surface average value are:

    • 5.3% (9 W/m²); over 1958–85 (Stanhill and Moreshet, 1992)[12]
    • 2%/decade over 1964–93 (Gilgen et al., 1998)[15]
    • 2.7%/decade (total 20 W/m²); up to 2000 (Stanhill and Cohen, 2001)[16]
    • 4% over 1961–90 (Liepert 2002)[17]

    Those are clearly not the only two options.

  10. Scientists probably have significantly underestimated how much the world’s oceans have warmed since the 1970s, according to a new study. The finding may force researchers to revise their gauges of some climate change effects, including the rate of sea-level rise.

    The study, by Paul J. Durack of Lawrence Livermore National Laboratory and others, found that the underestimation was the result of decades of spotty sampling of water temperatures in the Southern Hemisphere, home to three-fifths of the world’s oceans. Until 2004, when a worldwide system of autonomous floats, called Argo, became operational, there were relatively few temperature measurements south of the Equator.

    While atmospheric warming because of the trapping of heat by carbon dioxide and other greenhouse gases has most of the public’s attention, the oceans store far more of this heat. The study showed that the amount of heat absorbed by the top 2,200 feet of the oceans from 1970 to the mid-2000s may be as much as 58 percent higher than previously estimated.

    “We potentially may have missed a fair amount of heat that the ocean has been taking up,” Dr. Durack said.

    The researchers looked at global climate models, partitioned between north and south, and found a strong correlation between these simulations and data on sea-surface height as measured by satellites. But the models were not a good match for temperature, especially in the Southern Hemisphere. This suggested that the problem was not with the models so much as with the lack of temperature data before 2004. The study was published Sunday in the journal Nature Climate Change.

    Sea-level rise linked to climate change is related in part to increased melting of ice sheets and in part to the fact that water expands as it warms. So the finding that more heat has been taken up by the oceans may lead to revisions in estimates of the rate of sea-level rise. The finding also may affect assessments of how sensitive the climate is to the buildup of greenhouse gases in the atmosphere, the researchers said.
