2016 Arctic sea ice thread

[Crick]

You don't think air temperatures 10-15 degrees warmer than normal might have some effect on melt rates?

If you think the melt rate changes, then test it.

Okay. I froze a whole tray of ice overnight. I took half the cubes and placed them in my sink. I left the other half in the freezer. The ones in the sink melted much faster than the ones in the freezer.

Science.

But that difference is greater than 15 degrees. So test isn't valid for your hypothesis, fail.

Scaling.

From Wikipedia's article on PIOMAS

Sea ice thickness spatial extent, and open water within ice packs can vary rapidly in response to weather and climate.[1] Sea ice concentration are measured by satellites, with the Special Sensor Microwave Imager / Sounder (SSMIS), and the European Space Agency's Cryosat-2 satellite to map the thickness and shape of the Earth's polar ice cover.[2]The sea ice volume is calculated with the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS), which blends satellite-observed data, such as sea ice concentrations into model calculations to estimate sea ice thickness and volume. Sea ice thickness determines a number of important fluxes such as heat flux between the air and ocean surface—see below—as well as salt and fresh water fluxes between the ocean since saline water ejects much of its salt content when frozen—see sea ice growth processes. It is also important for navigators on icebreakers since there is an upper limit to the thickness of ice any ship can sail through.

From NSIDC.ORG

As of June 14, 2016, NSIDC has completed the transition to the Defense Meteorological Satellite Program (DMSP) F-18 satellite for sea ice data. Sea Ice Index updates have also resumed.

Sea ice data in Arctic Sea Ice News and Analysis are now based on the F-18 satellite beginning April 1, 2016. Data before April 1 are still from the F-17 satellite or earlier satellites in the series.

For more information on the F-17 satellite issues, see our April 12, 2016 post. On May 6, updates resumed with provisional F-18 data. These data are no longer considered provisional. However, these are near-real-time data and numbers may change when final data are obtained.

For more information on the satellite transition, see the documentation for the Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentrations data set.

Guess what jc? They don't use the same satellites. PIOMAS has not been down.

(CNN)The coverage of ice in the Arctic has dwindled to the lowest level ever seen for the month of May, according to the U.S. National Snow and Ice Data Center.

"During the month, daily sea ice extents tracked about 600,000 square kilometers (232,000 square miles) below any previous year in the 38-year satellite record," according to the center.
For perspective, 232,000 square miles is almost the size of Texas (about 86 percent) and that ice coverage has gone.
This follows a a string of lows from several months of 2016, meaning records were broken for the months of January, February, and April this year.

Scientists follow the sea ice cover as one of the key components of monitoring the climate. The Arctic sea ice extent has been a focus area because of its decline and what that tells us about global warming.
Since scientists began using satellite-based data in 1978, the Arctic ice cover has been declining at a rate of about 13 percent per decade, according to NASA.

Recent data indicate the ice is thinning and the air temperature is rising.
The temperature throughout May across the Arctic Ocean was about two to three degrees Celsius higher than the average seen between 1981 to 2010, according to the National Snow and Ice Data Center's report.

WTF is wrong with you? Different satellite. Only one has broken down or did you think they all go down at once. What satellite problem do you think NSIDC is suffering from?

"Problems with satellite sea ice monitoring confirmed by NSIDC – no timeline for fix
Anthony Watts / April 13, 2016


From NSIDC and the “worth blogging about” department

Sensor on F-17 experiencing difficulties, sea ice time series temporarily suspended

NSIDC has suspended daily sea ice extent updates until further notice, due to issues with the satellite data used to produce these images. The vertically polarized 37 GHz channel (37V) of the Special Sensor Microwave Imager and Sounder (SSMIS) on the Defense Meteorological Satellite Program (DMSP) F-17 satellite that provides passive microwave brightness temperatures is providing spurious data. The 37V channel is one of the inputs to the sea ice retrieval algorithms, so this is resulting in erroneous estimates of sea ice concentration and extent. The problem was initially seen in data for April 5 and all data since then are unreliable, so we have chosen to remove all of April from NSIDC’s archive."

February smashed monthly global temperature records, according to the satellite dataanalyzed by the University of Alabama at Huntsville (UAH). Climate science deniers need a new meme to replace their “satellites find no warming since 1998” talking point, which replaced the “there’s been no warming since 1998” talking point after that one fell apart when 2014 became the hottest year on record -- and again when 2015 blew away the 2014 record. In fact, for those who live in reality, as opposed to in denial, satellite data, ground-based weather stations, sea-based buoys, and even weather balloons all reveal a steady long-term warming trend. Let’s start with the UAH data, which show a stunning 1.5°F (0.83°C) warming in February 2016 compared to the historical (1981-2010) average for the lower troposphere (the lowest part of the atmosphere):

The lower tropospheric temperature (LT) anomaly, via UAH scientist Roy Spencer.

How amazing is this temperature jump? First off, remember that the 1981-2010 baseline used by the UAH is itself some 0.8°F (0.45°C) hotter than pre-industrial levels -- so you can add that to all of the numbers here. Second, February was more than half a degree Fahrenheit -- 0.52°F (0.29°C) -- warmer than January, which itself was “the warmest January in satellite record.” Third, it was so hot last month that Dr. Roy Spencer of the UAH reports, “Incredibly, land areas outside the tropics in the Northern Hemisphere were a 'whopping' 1.46 degrees C above average, 0.5 degrees above any previous monthly anomaly.” This is a 2.6°F warming above the 1981-2010 average -- topping the previous anomaly by 0.9°F. Fourth, it was so hot last month that Spencer -- one of country’s leading climate science deniers -- told the Washington Post: "I’ve always cautioned fellow skeptics that it’s dangerous to claim no warming. There has been warming." The UAH’s Spencer and Dr. John Christy — both leading deniers -- reported just last month that the UAH data shows a “Global climate trend since Nov. 16, 1978 [of] +0.12 C [0.22F] per decade.”

Pacific islands fighting for survival as sea levels rise

LONDON – Pacific islanders challenged world leaders this week to act on climate change, warning that their low-lying atolls are close to becoming uninhabitable because of rising seas and increasingly severe floods, droughts and storm surges. “The Pacific is fighting for its survival. Climate change has already arrived,” said Christopher Loeak, president of the Marshall Islands. The Marshall Islands, a group of 29 atolls and coral islands standing on average only two meters above sea level, and lying halfway between Australia and Hawaii, is particularly vulnerable to climate change. Many other small island Pacific “microstates,” including the Solomons, Tuvalu and the Carteret Islands, have all suffered rapid erosion, higher tides, storm surges and inundation of wells with seawater. Earlier this year Kiribati’s president, Anote Tong, predicted his country was likely to become uninhabitable because of inundation and contamination of its freshwater supplies.

EU climate commissioner Connie Hedegaard pledged last week to support the Pacific island states at the summit. “These low-lying islands risk being swamped by rising sea levels and their inhabitants forced to emigrate. Weather extremes in the Pacific are not about a distant future. They have become the new normal. Heat waves, floods, droughts and rising oceans are the new reality of an ever warming world."

EU "science" just concluded (after a 3 year study) that water does not prevent dehydration too, so what's your point again?

Really, Weatherman? You are actually basing that claim on a remarkably daft article by the Telegraph, which is part of the UK's tabloid swamp propagandizing against the EU? Here's a good run-down of that egregious stupidity, including a link to the actual ruling. I suggest you educate yourself, rather than to fall for such tabloid nonsense. Characterizing the EU based on a tabloid's willful misunderstanding and misrepresentation, however, is beyond infantile.

Everyone laughs at your ignorant, insane, unsupported, bullshit claims, LaDumbshit. You are a lying troll who repeats the same twaddle no matter how many times it gets debunked by the facts.

Is Sea Level Rising?
NOAA - Ocean Service
Yes, there is strong evidence that global sea level gradually rose in the 20th century and is currently rising at an increased rate, after a period of little change between AD 0 and AD 1900. Sea level is projected to rise at an even greater rate in this century. The two major causes of global sea level rise are thermal expan- sion of the oceans (water expands as it warms) and the loss of land-based ice due to increased melting.

Global sea level rose by about 120 m during the several mil- lennia that followed the end of the last ice age (approximately 21,000 years ago), and stabilised between 3,000 and 2,000 years ago. Sea level indicators suggest that global sea level did not change significantly from then until the late 19th century. The instrumental record of modern sea level change shows evidence for onset of sea level rise during the 19th century. Estimates for the 20th century show that global average sea level rose at a rate of about 1.7 mm yr–1.

Satellite observations available since the early 1990s provide more accurate sea level data with nearly global coverage. This decade-long satellite altimetry data set shows that since 1993, sea level has been rising at a rate of around 3 mm yr–1, significantly higher than the average during the previous half century. Coastal tide gauge measurements confirm this observation, and indicate that similar rates have occurred in some earlier decades.

In agreement with climate models, satellite data and hydro- graphic observations show that sea level is not rising uniformly around the world. In some regions, rates are up to several times the global mean rise, while in other regions sea level is falling. Sub- stantial spatial variation in rates of sea level change is also inferred from hydrographic observations. Spatial variability of the rates of sea level rise is mostly due to non-uniform changes in temperature and salinity and related to changes in the ocean circulation.

Near-global ocean temperature data sets made available in recent years allow a direct calculation of thermal expansion. It is believed that on average, over the period from 1961 to 2003, thermal expansion contributed about one-quarter of the observed sea level rise, while melting of land ice accounted for less than half. Thus, the full magnitude of the observed sea level rise during that period was not satisfactorily explained by those data sets, as reported in the IPCC Third Assessment Report.

During recent years (1993–2003), for which the observing system is much better, thermal expansion and melting of land ice each account for about half of the observed sea level rise, although there is some uncertainty in the estimates.

The reasonable agreement in recent years between the observed rate of sea level rise and the sum of thermal expansion and loss of land ice suggests an upper limit for the magnitude of change in land-based water storage, which is relatively poorly known. Mod- el results suggest no net trend in the storage of water over land due to climate-driven changes but there are large interannual and decadal fluctuations. However, for the recent period 1993 to 2003, the small discrepancy between observed sea level rise and the sum of known contributions might be due to unquantified human- induced processes (e.g., groundwater extraction, impoundment in reservoirs, wetland drainage and deforestation).

Global sea level is projected to rise during the 21st century at a greater rate than during 1961 to 2003. Under the IPCC Special Report on Emission Scenarios (SRES) A1B scenario by the mid- 2090s, for instance, global sea level reaches 0.22 to 0.44 m above 1990 levels, and is rising at about 4 mm yr–1. As in the past, sea level change in the future will not be geographically uniform, with regional sea level change varying within about ±0.15 m of the mean in a typical model projection. Thermal expansion is pro- jected to contribute more than half of the average rise, but land ice will lose mass increasingly rapidly as the century progresses. An important uncertainty relates to whether discharge of ice from the ice sheets will continue to increase as a consequence of accel- erated ice flow, as has been observed in recent years. This would add to the amount of sea level rise, but quantitative projections of how much it would add cannot be made with confidence, owing to limited understanding of the relevant processes.

Figure 1 shows the evolution of global mean sea level in the past and as projected for the 21st century for the SRES A1B scenario.

FAQ 5.1, Figure 1. Time series of global mean sea level (deviation from the 1980-1999 mean) in the past and as projected for the future. For the period before 1870, global measurements of sea level are not available. The grey shading shows the uncertainty in the estimated long-term rate of sea level change (Section 6.4.3). The red line is a reconstruction of global mean sea level from tide gauges (Section 5.5.2.1), and the red shading denotes the range of variations from a smooth curve. The green line shows global mean sea level observed from satellite altimetry. The blue shading represents the range of model projections for the SRES A1B scenario for the 21st century, relative to the 1980 to 1999 mean, and has been calculated independently from the observations. Beyond 2100, the projections are increasingly dependent on the emissions scenario (see Chapter 10 for a discussion of sea level rise projections for other scenarios considered in this report). Over many centuries or millennia, sea level could rise by several metres (Section 10.7.4).

 

[LaDexter]

cut paste and parrot...

The Marshall Islands are sinking, but not because of any fictitious sea level rise.

That our resident birdbrain cannot find an article to parrot saying residents are fleeing Hawaii is par for the course. Hawaii is NOT SINKING, because there is NO SEA LEVEL RISE, in part because the planet has NO NET ICE MELT ongoing, since 90% of Earth ice on Antarctica has added at least 80 billion tons of ice every year since Algore started lying about CO2...

New York has it's own problem with sea level rise.

Sea Level Rise - NYS Dept. of Environmental Conservation

Fast Facts - Sea-level Rise in New York

• New York has an estimated 1,850 miles of tidal shoreline exposed to the action of tides, wind and waves - much of it developed and densely populated.
• New York has experienced at least a foot of sea-level rise since 1900, mostly due to expansion of warming ocean water. Certain conditions along New York's coast make sea-level rise here somewhat higher than the global average.
• New York's coastal marine counties already see more intense storm surges and floods. Superstorm Sandy highlighted the risks and vulnerabilities of our tidal shorelines, which are home to more than half of New Yorkers.
• By 2100, scientists project sea levels 18 to 50 inches higher than today along New York's coastlines and estuaries, though a rise as high as 75 inches could occur.
• Sea-level rise is locked in for centuries, or even millennia, by heat-trapping greenhouse gases already in the atmosphere. Continuing or increasing emissions will speed up the rise to higher levels.
• Energy, land use and infrastructure decisions made now will determine how vulnerable our children and grandchildren will be to rising sea-levels.

Like many low-lying coastal cities around the world, Miami is threatened by rising seas. Whether the majority of the cause is anthropogenic or natural, the end result is indisputable: sea level is rising. It is not a political issue, nor does it matter if someonebelieves in it or not.


Tidal flooding on the corner of Dade Blvd and Purdy Ave in Miami Beach in 2010. (Steve Rothaus, Miami Herald)

The mean sea level has risen noticeably in the Miami and Miami Beach areas just in the past decade. Flooding events are getting more frequent, and some areas flood during particularly high tides now: no rain or storm surge necessary. Perhaps most alarming is that the rate of sea level rise is accelerating.

The mean sea level has risen noticeably in the Miami and Miami Beach areas just in the past decade. Flooding events are getting more frequent, and some areas flood during particularly high tides now: no rain or storm surge necessary. Perhaps most alarming is that the rate of sea level rise is accelerating.

OMG! Flooding on a sandbar 2 feet above sea level!

Thanks for the link!

Why does Sea Level change over time?

There are a number of factors that contribute to long and short-term variations in sea level. Short-term variations generally occur on a daily basis and include waves, tides, or specific flood events, such as those associated with a winter snow melt, or hurricane or other coastal storm. Long-term variations in sea level occur over various time scales, from monthly to several years, and may be repeatable cycles, gradual trends, or intermittent anomalies. Seasonal weather patterns, variations in the Earth's declination, changes in coastal and ocean circulation, anthropogenic influences (such as dredging), vertical land motion, and the El Niño Southern Oscillation are just a few of the many factors influencing changes in sea level over time. When estimating sea level trends, a minimum of 30 years of data are used in order to account for long-term sea level variations and reduce errors in computing sea level trends based on monthly mean sea level. Accounting for repeatable, predictable cycles, such as tidal, seasonal, and interannual variations allows computation of a more accurate long-term sea level trend.

Is that water there today? LOL. Floods are now sea level rise.
