Nice graphic where the water is coming from. "1,386 million cubic kilometers (km3)" all the water of the earth. Maybe EPA should check with usgs on the 3.5 meter increase. ga.water.usgs.gov/edu/earthhowmuch.html

"The authors of the IPCC report have come to the view, having looked at the available scientific evidence, that it is very likely that most of the warming of the past 50 years is due to man."
Steve, I tend to agree with the IPCC on just how much we have warmed over the last century. However, I tend to become skeptical on just how much we will continue to warm based on the models performance. Even if most of the 1.2 degrees of warming is caused by man there is still a large window of uncertainty in the forecasts. I fail to believe that we have a full grasp on the solar effects, multidecadal oscillations and the numerous other factors that have an effect on our climate.
I would guess, and it is only a guess that as time goes by and we get a better grasp on the drivers of our climate our emphasis on CO2's role will diminish. Yes it is a greenhouse gas, yes it has a role but perhaps not as big a role as some currently think.

Lots of Earth not much water. Shocked me as well.

Not to worry Mr. Green has all the controls in his hands. Even validated by proxy authority. Makes sense to me as sea level has been static to falling recently. But if it did and maybe .... then Oh its worse than we thought! "New figures: More of US at risk to sea level rise" ""It's shocking to see how large the impacts could be, particularly in southern Florida and Louisiana, but much of the coastal U.S. will share in the serious pain," Overpeck said. Sea level has already risen about 8 inches since 1880 because of warmer waters expand, Strauss said. Sea level rise experts at the U.S. Geological Survey and the National Oceanic Atmospheric Administration who weren't part of the studies said the results make sense and were done by experts in the field." www.cbsnews.com/8301-505245_162-57397018/new-figures-more-of-us-at-risk-to-sea-level-rise/

How fast is it, 1 to 4 mm per year "1. GPS-monitored global tide gauges In 2009 Guy Woppelmann et al examined what effects vertical land movement had on the sea level data from tide gauges and published their results in the Geophysical Research Letters. The scientists evaluated globally 227 stations whose elevation was monitored by GPS. 160 of these stations were located at a distance maximum 15 km from the coast. By measuring the vertical movement of the tide gauges, they were able to apply a correction. From this they calculated a mean global sea level rise of 1.61 mm/year over the last century. Figure 1 shows that sea level rise has remained constant since 1940, no acceleration over the last 70 years! " "In summary, our global sea level journey produced some good results, some very remarkable results, depending on your point of view. Signs of an accelerating sea level over the last 30 years could not be found in any of the studies. It doesn’t look good for the acceleration fans. " icecap.us/index.php/go/new-and-cool

Well, there HAS been an acceleration in adjustments...

60 year cycle never heard of a 60 year CO2 cycle, Oh the sun again. "Sea Level Acceleration: Not so Fast Recently" "For this reason, Chambers et al. note: The 60-year oscillation will, however, change our interpretation of the trends when estimated over periods less than 1-cycle of the oscillation. Although several studies have suggested the recent change in trends of global [e.g., Merrifield et al., 2009] or regional [e.g., Sallenger et al., 2012] sea level rise reflects an acceleration, this must be re-examined in light of a possible 60-year fluctuation. While technically correct that the sea level is accelerating in the sense that recent rates are higher than the long-term rate, there have been previous periods were the rate was decelerating, and the rates along the Northeast U.S. coast have what appears to be a 60-year period [Figure 4 of Sallenger et al., 2012], which is consistent with our observations of sea level variability at New York City and Baltimore. Until we understand whether the multi decadal variations in sea level reflect distinct inflexion points or a 60-year oscillation and whether there is a [Global Mean Sea Level, GMSL] signature, one should be cautious about computations of acceleration in sea level records unless they are longer than two cycles of the oscillation or at least account for the possibility of a 60-year oscillation in their model. This especially applies to interpretation of acceleration in GMSL using only the 20-year record of from satellite altimetry and to evaluations of short records of mean sea level from individual gauges. [emphasis added –eds.] The bottom line is this: the more people look for the anticipated acceleration in the rate of sea level rise, the less evidence they seem to find in support of it. All the while, we eat into the 21st century with a rate of sea level rise not much different from that experienced during the 20th century—and one which was hardly catastrophic, readily proven by a simple look around." wattsupwiththat.com/2012/09/13/sea-level-acceleration-not-so-fast-recently/#more-70961
