Sentences with phrase «recent sea level data»

Radiative forcing is increasing roughly quadratically, so a quadratic fit to recent sea level data to make predictions seems far more reasonable.

Recent methane measurements at Terceira Island, Azores, Portugal and Tae - ahn Peninsula, Republic of Korea (See http://www.esrl.noaa.gov/gmd/dv/iadv/index.php) in the context of outlier data points over the last decade at sites such as Storhofdi, Vestmannaeyjar, Iceland, and reports of methane releases from the Arctic seabed, tell us that at current levels of AGW, the Earth's sea - floor methane systems are not stable.

Compared to the data on sea level rise through 1990, the more recent rate of rise is far steeper than earlier research had suggested.

Here we analyze a series of climate model experiments along with observational data to show that the recent warming trend in Atlantic sea surface temperature and the corresponding trans - basin displacements of the main atmospheric pressure centers were key drivers of the observed Walker circulation intensification, eastern Pacific cooling, North American rainfall trends and western Pacific sea - level rise.

The satellites are very new and recent data overlapping old data, the whole idea that the planet is a sphere has been tossed as mass concentrations affecting sea level are mapped.

Dr. Ringot, an Antarctic and Greenland specialist and coauthor on Hansen's recent paper on sea level rise, claimed that their data indicated that the West Antarctic Ice Sheet alone would melt in decades to centuries with a sea level rise of at least 10 feet.

Projections for global sea level rise by 2100 range from 8 inches to 6.6 feet above 1992 levels, though the lowest end of this range is a simple extension of historic sea level rise — and recent data indicate this rate has nearly doubled in recent years.

Update (26th March 2015): Indeed, a recent paper by Jens Morten Hansen et al. has suggested that, after accounting for the post-glacial rebound effects discussed above, the 18.6 year lunar cycle (and multiples of it) can explain most of the non-linear trends in the sea level data for the North Sea and Baltic Sea — see Hansen et al., 2015 (Abstracsea level data for the North Sea and Baltic Sea — see Hansen et al., 2015 (AbstracSea and Baltic Sea — see Hansen et al., 2015 (AbstracSea — see Hansen et al., 2015 (Abstract).

Rahmstorf, Foster, and Cazenave (2012) compares the historical sea level tide gauge data from Church and White (2011) and recent satellite altimetry sea level data (orange and red in Figure 4, respectively) to the 2001 and 2007 IPCC report model projections (blue and green in Figure 4, respectively).

I do hope that the (much - hyped) issue of global sea - level rise and putative recent acceleration will be examined seriously here as a geophysical problem and not be subjected to summary number - crunching by inept blog lions who naively think that simple detrending of highly different tide - gauge records alleviates all issues of establishing a common datum - level.

The long - term tide gauges in the Mediterranean show sea - level trends for the 20th century in the range of 1.1 — 1.3 mm / yr whilst more recent satellite altimetry data reveals much larger increases in sea - level throughout the basin towards the latter part of the century.

Meanwhile, up in the Arctic, distressing new information from the US National Snow and Ice Data Center in Boulder, Colorado, shows that Arctic sea ice extent has settled to its fourth - lowest level ever measured at the end of the most recent melt season.

«Second, in contrast to the previously reported slowing in the rate during the past two decades1, our corrected GMSL data set indicates an acceleration in sea - level rise (independent of the VLM used), which is of opposite sign to previous estimates and comparable to the accelerated loss of ice from Greenland and to recent projections, and larger than the twentieth - century acceleration.

Bill Innis: Jevrejeva's most recent tide gauge data from 2003 to 2009 shows sea level is actually falling The data will likely become available soon.

In a recent paper, paleoclimatic data shows that the tropical monsoon cycle responds very reliably to the ups and downs of Milankovitch insolation forcing on one of the shorter time scales (either 23kyr 65N forcing swings or the 41kyr obliquity cycle, I forget which), but the ice sheets and sea level and global temperature do not respond directly to those insolation forcings.

There is strong evidence, discussed above, that the sea level was several metres higher in recent warm interglacial periods, consistent with our data interpretation.
