Sentences with phrase «average sea level measurements»

Not exact matches

That measurement included only the height above the average level of the sea and did not consider the depth of the wave trough.

Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

Data from satellite measurements show that sea levels have increased by about three inches on average worldwide since 1992 suggesting that sea levels are rising more quickly than anticipated and faster than they did 50 years ago.

Global average sea levels have risen by around 3.2 mm per year since satellite measurements began in 1993, the report says, with sea levels around 67 mm higher in 2014 than they were in 1993.

The average rate of sea - level rise in the 20th century was 15 cm / century, but in the quarter - century since 1990 it has been 30 cm / century and is showing signs of further acceleration in more recent measurements.

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.

NSIDC 5 day averaged Antarctic sea ice extent is now at a record low level for the date, since satellite measurements began in 1979:

The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and, indirectly, from increases in average global sea levels, retreating glaciers, and changes in many physical and biological systems.

I've been doing climate database work for a long time and have learned a few shortcut methods that made it at least possible to get an average sea level out of the measurements.

[5] From 1950 to 2009, measurements show an average annual rise in sea level of 1.7 ± 0.3 mm per year, with satellite data showing a rise of 3.3 ± 0.4 mm per year from 1993 to 2009, [6] a faster rate of increase than previously estimated.

I can't begin to imagine what a frank, honest, apolitical climate scientist or physicist would have to say about all the assumptions and statistical legerdemain that goes into coming up with such precise «measurements» of global average sea level.

Assuming 9 million square km of the ice sheet have few measurements, that works out to a ratio of 40:1: a 40 cm lowering of average ice sheet height would produce a 1 cm rise in sea level.

Since 1992, global mean sea level can be computed at 10 - day intervals by averaging the altimetric measurements from the TOPEX / Poseidon (T / P) and Jason satellites over the area of coverage (66 ° S to 66 ° N)(Nerem and Mitchum, 2001).
