Sentences with phrase «relative sea level trends»

The report Gray cites states clearly that relative sea level trends (1992/3/4 to 2006) at all stations were positive (2.7 to 8.1 mm / year for the 11 of the 12 stations with long enough records).

Simple mean relative sea level trends of the PSMSL stations in the map above.

Not exact matches

The increase in rate relative to the 1901 — 90 trend is accordingly larger than previously thought; this revision may affect some projections11 of future sea - level rise.

As he pointed out, a dominant unforced contribution to surface warming relative to forced trends would be expected to be accompanied by a trend of declining OHC, which is inconsistent with the observed trends averaged over the past half century as evidenced by mixed layer temperature measurements and sea level rise.

The map of regional mean sea level trends provides an overview of variations in the rates of relative local mean sea level observed at long - term tide stations (based on a minimum of 30 years of data in order to account for long - term sea level variations and reduce errors in computing sea level trends based on monthly mean sea level).

Stations illustrated with negative trends (blue - to - purple) are experiencing global sea level rise and a greater vertical rise in the local land, causing an apparent decrease in relative sea level.

Stations illustrated with positive sea level trends (yellow - to - red) are experiencing both global sea level rise, and lowering or sinking of the local land, causing an apparently exaggerated rate of relative sea level rise.

For example, additional evidence of a warming trend can be found in the dramatic decrease in the extent of Arctic sea ice at its summer minimum (which occurs in September), decrease in spring snow cover in the Northern Hemisphere, increases in the global average upper ocean (upper 700 m or 2300 feet) heat content (shown relative to the 1955 — 2006 average), and in sea - level rise.

Due to the extreme rate of CO ₂ and temperature rise during the 20th century relative to earlier events and the non-linearity of climate change trends the timing of sea level rise may be difficult to estimate.

The observed changes (lower panel; Trenberth and Fasullo 2010) show the 12 - month running means of global mean surface temperature anomalies relative to 1901 — 2000 from NOAA [red (thin) and decadal (thick)-RSB- in °C (scale lower left), CO2 concentrations (green) in ppmv from NOAA (scale right), and global sea level adjusted for isostatic rebound from AVISO (blue, along with linear trend of 3.2 mm / year) relative to 1993, scale at left in mm).
