Gilding lilies with PhotoShop – Mount Fuji and cloud version

November 16, 2012

Take a photo of amazing stuff:

Then mess it up with PhotoShop:

Why?  It’s the old question of why do we need fairies in the garden — isn’t the garden itself enough?

Phil Plait at Bad Astronomy called attention to other fantastic lenticular clouds near Mt. Fuji — are those fantastic formations not enough?

Did the PhotoShopper add anything of value to the picture?  Of what use is a gilded lily?

(Please help — the original photo is identified as an award winner in 2003 — do you know the original photographer?  We should give credit appropriately; I’ve not found the person’s name, yet.)

Annals of global warming: Glaciological map of Antarctica’s Palmer Land Area, 1947-2009

March 3, 2010

Are the ice fields of Antarctica increasing or decreasing?  How do we know?

U.S. Geological Survey released a study of the change in glaciation in Antarctica between 1947 and 2009.  Serious student of climate change will heed what the maps show — better bookmark the site.  The study and publication were done in a joint effort of USGS, the British Antarctic Survey, the Scott Polar Research Institute, and the Bundesamt für Kartographie und Geodäsie (same page, in English, here).

Reduction in the area and volume of the two polar ice sheets is intricately linked to changes in global climate, and the resulting rise in sea level could severely impact the densely populated coastal regions on Earth. Antarctica is Earth’s largest reservoir of glacial ice. Melting of the West Antarctic part alone of the Antarctic ice sheet would cause a sea-level rise of approximately 6 meters (m), and the potential sea-level rise after melting of the entire Antarctic ice sheet is estimated to be 65 m (Lythe and others, 2001) to 73 m (Williams and Hall, 1993). The mass balance (the net volumetric gain or loss) of the Antarctic ice sheet is highly complex, responding differently to different climatic and other conditions in each region (Vaughan, 2005). In a review paper, Rignot and Thomas (2002) concluded that the West Antarctic ice sheet is probably becoming thinner overall; although it is known to be thickening in the west, it is thinning in the north. The mass balance of the East Antarctic ice sheet is thought by Davis and others (2005) to be positive on the basis of the change in satellite-altimetry measurements made between 1992 and 2003.

Measurement of changes in area and mass balance of the Antarctic ice sheet was given a very high priority in recommendations by the Polar Research Board of the National Research Council (1986), in subsequent recommendations by the Scientific Committee on Antarctic Research (SCAR) (1989, 1993), and by the National Science Foundation’s (1990) Division of Polar Programs. On the basis of these recommendations, the U.S. Geological Survey (USGS) decided that the archive of early 1970s Landsat 1, 2, and 3 Multispectral Scanner (MSS) images of Antarctica and the subsequent repeat coverage made possible with Landsat and other satellite images provided an excellent means of documenting changes in the cryospheric coastline of Antarctica (Ferrigno and Gould, 1987). The availability of this information provided the impetus for carrying out a comprehensive analysis of the glaciological features of the coastal regions and changes in ice fronts of Antarctica (Swithinbank, 1988; Williams and Ferrigno, 1988). The project was later modified to include Landsat 4 and 5 MSS and Thematic Mapper (TM) images (and in some areas Landsat 7 Enhanced Thematic Mapper Plus (ETM+) images), RADARSAT images, aerial photography, and other data where available, to compare changes that occurred during a 20- to 25- or 30-year time interval (or longer where data were available, as in the Antarctic Peninsula). The results of the analysis are being used to produce a digital database and a series of USGS Geologic Investigations Series Maps (I-2600) (Williams and others, 1995; Swithinbank and others, 2003a,b, 2004; Ferrigno and others, 2002, 2005, 2006, 2007, 2008, and in press; and Williams and Ferrigno, 2005) (available online at http://www.glaciers.er.usgs.gov).

The paper version of this map is available for purchase from the USGS Store.

What’s the condition of glaciers in Antarctica?  Now you can look it up.

The pamphlet accompanying the maps says under “Discussion”:

The most noticeable and dramatic changes that can be seen on the Palmer Land area map are the retreat of George VI, Wilkins, Bach, and northern Stange Ice Shelves. The northern ice front of George VI Ice Shelf was at its farthest extent during our period of observation between 1966 and 1974. It retreated, losing 906 km2 between 1974 and 1992 and 87 km2 between 1992 and 1995. After 1995, it retreated an additional 1 km to more than 6 km by 2001. The southern George VI ice front retreated considerably from 1947 to the late 1960s. From the late 1960s to 1973, there was additional substantial retreat, the greatest during the period of measurements.  From 1973 to 2001, there was overall noticeable retreat.

Wilkins Ice Shelf had four ice fronts up till 2009; all retreated during the time period of our study, but Wilkins “a” and “b” have had the most dramatic change, including extensive calving in 2009 that eliminated ice front “b” and threatened the future of the ice shelf. During the period of observation, the Bach Ice Shelf front maintained a fairly consistent profile, and advanced or retreated at the same time along the entire ice front. The overall trend of Bach Ice Shelf is retreat. On the northern Stange Ice Shelf during the period of observation, the 1947, 1965–66, 1973, and 1986 ice fronts were more advanced, and the 1997 and 2001 ice fronts were more in retreat. However, the earlier data are less accurate geographically, and it is difficult to quantitatively analyze them. The later satellite images are more accurate, and it is possible to measure overall advance from 1986 to 1989, then retreat from 1989 to 1997 and from1997 to 2001; the net result was retreat.

The three coastal-change and glaciological maps of the Antarctic Peninsula (I–2600–A, –B, and –C) portray one of the most rapidly changing areas on Earth. The changes exhibited in the region are widely regarded as among the most profound and unambiguous examples of the effects of global warming yet seen on the planet.

Where’s that global cooling the denialists promised?

January 20, 2010

Forgetting that the planet has seasons, climate denialists for months have been hoo-hooing  about snowfalls and cold weather.  Some of the more serious propagandists among them claim that the Earth is now in a cooling cycle, and that temperatures have been falling since the record hot year of 1998.

Really?

Head on over to Open Mind, and take a look at the facts.

NASA GISS [Goddard Institute for Space Studies] has released the estimated monthly temperature for December 2009, which closes out the year 2009, which closes out the decade of the 2000s. The result: 2005 is still the hottest calendar year, 2009 is the 2nd-hottest year ever, although it’s really in a statistical tie with 1998, 2002, 2003, 2006, and 2007.

They’ve confused weather with climate.  They’ve failed to keep score.  Perhaps they’ve spent wasted their time hacking e-mails instead of measuring climate.

RealClimate carries the news in a post by some of NASA’s top scientists, including James Hansen:

The past year, 2009, tied as the second warmest year in the 130 years of global instrumental temperature records, in the surface temperature analysis of the NASA Goddard Institute for Space Studies (GISS). The Southern Hemisphere set a record as the warmest year for that half of the world. Global mean temperature, as shown in Figure 1a, was 0.57°C (1.0°F) warmer than climatology (the 1951-1980 base period). Southern Hemisphere mean temperature, as shown in Figure 1b, was 0.49°C (0.88°F) warmer than in the period of climatology.

How will the critics treat this news?  And, what were they doing during the past decade when all those warm days rolled into weeks, rolled into months and years, and finally, to the warmest decade ever?

Climate change skeptics, your Freudian slip is showing

August 21, 2008

Is the climate change debate about science, or politics?

Anthony Watts’s blog settled the question yesterday. Watts has been conducting surveys of U.S. weather reporting stations in a months-long campaign to make a case that data have been skewed by inappropriate sitings of the measuring equipment. Other posts on the blog celebrate every release of information that might be construed as contrary to warming or contrary to human effects on climate, or denigrating any release that supports a claim of change or that human activities cause the change.

The U.S. Climate Change Science Program released a draft report for public comment several weeks ago. Watts criticized the report for a tone he interpreted as advocacy instead of science. Since comments on the report are wide open, as required under the Administrative Procedures Act, comments like Watts’ can be submitted to the agency, and they must be answered. Watts’ invitation to people who disagree with any part of the report is a good encouragement for people to take a part in this important debate about public policy.

But then, yesterday, Watts posted the smoking gun showing political pushing of the science from the White House, unintentionally, I’m sure. In fact, Watts hailed the thing, with a headline claiming that the report was being “pulled.”

Reading through Watts’s post it is difficult to figure out what happened that prompted the headline — it’s hidden away in his quote of the attack-dog propaganda site at National Review On-line, Watts said:

Chris Horner writes on NRO Planet Gore:

…the U.S. Chamber pointed out that a preponderance of the 21 reports that had purportedly been “synthesized” had not actually been produced yet. Sure, that sequence sounds odd in the real world, but is reminiscent of the IPCC, to which the USP appealed as the authority for certain otherwise unsupported claims (though the IPCC openly admits that it, too, performs no scientific research). This is a point we also made in our comments. I’m informed that NOAA has now agreed to publish the underlying documents first and then put out their desired USP. The Chamber should have a release out soon.

Did you catch that? It’s in the line, “NOAA has now agreed.” So what is the document at NOAA referred to?

Oh, it’s not a document from NOAA. It is a memorandum from the anti-climate change science group set up by the U.S. Chamber of Commerce, from William Kovacs, an employee of the U.S. Chamber.

A few days ago I received a call from the administration informing me that, while they will not withdraw the notice for comments, it will in the next several weeks file another Federal Register notice providing for comment when all of the synthesis reports are public.

It seems to me that the APA rules and procedures are quite clear. Comments must be accepted, and generally they must be commented upon. Comments to the effect that not all the material backing the report was available are fair game, must be answered by the agency, and if true, might make a case for more careful scrutiny of any regulation coming from the report.

What did NOAA do? Nothing that we can see. Instead, what’s got Watts happy is a note from a hardball political group that they’ve heard from the White House, suggesting there will be political philandering with the science report.

Good scientists have significant science findings that would mitigate or contradict findings expressed in the draft report. Pointing those studies out to NOAA and the Climate Change Science Program would be the way to make a solid case.

The skeptics’ asking the White House to politically kill the report, and then celebrating a missive from a lobbying group that claims the report has been killed contrary to the law under the Administrative Procedures Act, doesn’t suggest that science is the concern of the skeptics — at least, that’s not the message I get.

In the wake of the news of one probably illegally suppressed report, it’s probably not wise to celebrate the suppression of another, legal or not.

Update: As of Thursday afternoon (August 21), Watt’s Up With That? has changed the headline from “pulled” to “hold.”

The same criticisms apply from above, still.
