Again, Monckton must surely know full well that for the last 25 - 30 years satellite temperature measurement of sea and land surface have replaced terrestrial temperature station measurements in many cases since these give a much greater coverage (70 % of the surface of the Earth is water... it's difficult to put weather stations on top of ice sheets etc.!)

In the fall, the team also will begin its yearly measurements of land and sea ice in Antarctica.

2) loss of land based ice: both land based observations (Glacier National Park for instance) and satellite gravity measurements make it clear that land based ice is decreasing.

Unfortunately the best description of it I can't find again but it basically models the earths crust and tries to provide a reasonable assumption of how much the crust would rise and this is used with the GRACE measurements to determine how much mass is ice and how much is land.

Therefore I strongly doubt that the «rising» of the land has any appreciable bearing upon our estimates of ice loss in Antarctica, whether they are based upon gravity measurements via satellites or laser altimetry.

Composite satellite measurements of sea surface temperature (SST) and real - color land and sea ice images for the end of the summer 2011 season in the Pacific Arctic.

Challenges and recommendations in mapping of glacier parameters from space: results of the 2008 Global Land and Ice Measurements from Space (GLIMS) workshop, Boulder, Colorado, USA.

Yet we know the land around then Arctic is warming faster than the global average so it seems unreasonable to suggest that the ocean isn't, Satellite temperature measurements up to 82.5 N support this as does the decline of Arctic sea ice here, here & here.

From that link's words, the DMI «green line» IS the best way to consistently compare the daily estimate of NORTH areas of the arctic — those areas north of 70 latitude to 83 north latitude NASA - GISS extrapolates «surface» ground - based temperatures as far as 1200 km from where their land - based measurements were made from 60 - 70 latitude over the ever - greening (and darker) tundra and forests OUT to the open sea where where the arctic sea ice actually is present.

Many more flawed or misleading presentations of Global Warming science exist in the book, including those on Arctic sea ice thinning, correction of land - based temperature measurements for the urban heat island effect, satellite vs. ground - based measurements of Earth's warming, and controversies over sea level rise estimates.

These measurements provide the first direct evidence that Western Palmer Land is losing ice due to increased glacier flow — a process known as dynamical imbalance.

A few groups have attempted to construct sea ice estimates for the pre-satellite era using various combinations of land, ship, submarine, buoy and aircraft measurements made over the years, e.g., the Chapman & Walsh dataset or the Zakharov dataset (Note that the server for the Zakharov dataset is not always online, so the link sometimes doesn't work).

Until recently, the contribution of ice sheets to sea - level rise remained unknown and is still debated, but the current acceleration of sea - level rise is attributed to heating of the oceans and melting of land glaciers which is supported by measurements of ocean temperatures and the behavior of mountain glaciers, the vast majority of which are retreating or exhibit signs of instability.

We know it from direct measurements of land and water, from shifts in where animals and plants live, from rapid increases in glacier and ice sheet melt, from sea level rise (due less to melting ice, and more to expansion as the water warms).

Steve Nerem, the director of the widely relied - upon research center, told FoxNews.com that his group added the 0.3 millimeters per year to the actual sea level measurements because land masses, still rebounding from the ice age, are rising and increasing the amount of water that oceans can hold.

[It] is based on measurements made by many independent institutions worldwide that demonstrate significant changes on land, in the atmosphere, the ocean and in the ice - covered areas of the Earth.»

The local offset (~ 40 ppmv in Giessen, SW Germany) can be calibrated away by comparing the stomata data to direct measurements and ice cores in the previous century, but nobody knows the influence of land use changes in the main wind directions and of changes in the main wind directions themselves (MWP - LIA) in the course of the centuries.

This new research combines measurements of ocean heat, land and atmosphere warming and ice melting to find that our climate system continued to accumulate heat through to 2008.
