I’ve been there only once. A wise American would get there before turning 35, and return several times.
Want solid information on climate change (global warming) and the problems it poses?
Several opportunities present themselves, from the National Academies of Science, America’s premiere science advisory group:
America’s Climate Choices Final Report in Review
The final report of the America’s Climate Choices suite of studies is in the final stages of peer review and will be released this Spring. An official release date will be announced as soon as possible. The report is authored by the Committee on America’s Climate Choices, which was responsible for providing overall direction, coordination, and integration of the America’s Climate Choices activities.
“Warming World: Impacts by Degree” Explains Findings of NRC Report
Emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch, beginning to be called the Anthropocene, during which human activities will largely determine the evolution of Earth’s climate. That’s one of the main conclusions from Climate Stabilization Targets: Emissions, Concentrations, and Impacts over Decades to Millennia (NRC, 2011) an expert consensus report released last July and published this year. Now a new 36-page booklet based on the report, “Warming World: Impacts by Degree” is available to help policymakers, students, and the general public better understand the report’s important conclusions.
The report concludes that, because carbon dioxide is so long-lived in the atmosphere, increases in this gas can effectively lock the Earth and many future generations in a range of impacts, some of which could be severe. Therefore, emission reduction choices made today matter in determining impacts that will be experienced not just over the next few decades, but also into the coming centuries and millennia. Policy choices can be informed by recent advances in climate science that show the relationships among increasing carbon dioxide, global warming, related physical changes, and resulting impacts. The report identifies (and quantifies when possible) expected impacts per degree of warming, including those on streamflow, wildfires, crop productivity, the frequency of very hot summers, and sea-level rise and its associated risks and vulnerabilities.

Report Sets Research Agenda to Study Earth’s Past Climate
Without a reduction in emissions, by the end of this century atmospheric carbon dioxide could reach levels that Earth has not experienced for more than 30 million years. Critical insights into how Earth’s atmosphere, oceans, and ecosystems would function in this high carbon dioxide environment are contained in the records of Earth’s geological past, concludes Understanding Earth’s Deep Past: Lessons for Our Climate Future, a National Research Council report from the Board on Earth Sciences that was released on March 1, 2011.
“Ancient rocks and sediments hold the only records of major, and at times rapid, transitions across climate states and offer the potential for a much better understanding of the long-term impact of climate change,” said Isabel Montañez, chair of the committee that wrote the report and a professor in the department of geology at the University of California, Davis. The research could also yield information on the tipping points for climate change–the threshold of greenhouse gas accumulation in the atmosphere at which abrupt climate change will occur.
The report sets out a research agenda for an improved understanding of Earth system processes during the transition to a warmer world. High-priority research initiatives include gaining a better understanding of the sensitivity of climate to increased atmospheric carbon dioxide, the amount of sea-level rise as the ice sheets melt, and the resilience of ecosystems to climate change.
Webinar on Transportation and Climate Change

Speaking of Faith is carried on many public radio stations nationally, perhaps on one in your area. If, as I do, you live in an area where the program is not carried, you can pick up a podcast or .mp3 at the program’s website. (Here’s a list of stations that carry the broadcast.)
Host Krista Tippett posts a weekly message on the scheduled program — this week, an interview with Bill McKibben, whose book, The End of Nature, was a popular introduction to climate change, when it was published in 1989 (!).
Yes, this program is about woo and how we deal with it in our daily lives. This particular program looks at how even woo followers may find it to their advantage to pay attention to the science, and act to protect their families and communities as a result. This is a moral side of climate change that too many people simply deny.
Ms. Tippett wrote:
This week on public radio’s conversation about religion, meaning, ethics, and ideas:
Bill McKibben’s first book, The End of Nature, was the first popular book on climate change, and he is one of the most insightful figures of our time on ecology and life. We’ll explore his hopeful sense that what is good for the environment also nourishes human relationship. And we’ll seek his perspective on knowledge we can trust as we orient our minds and lives to changing realities of the natural world.
History Tends to Surprise Us
It’s been striking how, across the past few years, the environment has found its way inside my guests’ reflections on every subject, as they say, under the sun. And we do need fresh vocabulary and expansive modes of reflection on this subject that, we’ve come to realize, is not just about ecology but the whole picture of human life and lifestyle.
Here are some pieces of vocabulary and perspective I’ve loved and used in recent years.
Starting with the basics, Cal DeWitt — a scientist, conservationist, and Evangelical Christian living in Wisconsin — pointed out to me that “environment” was coined after Geoffrey Chaucer used the term “environing.” This was a turning point in the modern Western imagination — the first time we linguistically defined ourselves as separate from the natural world, known up until then as the Creation. This helps explain why the language of “creation care” is so animating for many conservative Christians — as a return to a sacred insight that was lost. But from quantum physics to economics, too, we are discovering new existential meaning in terms like interconnectedness and interdependence.
Many people, but most recently the wonderful geophysicist Xavier le Pichon, have made the simple yet striking observation that climate change is the first truly global crisis in human history. In other words, just as we make newfound discoveries about old realities, they are put to the ultimate test. It is easy to be overwhelmed by the signs that we are not up to this test as a species. So it was helpful for me to have Matthieu Ricard, a biologist turned Buddhist monk, remind me that evolutionary change, which is what we need now in our behavior, always comes precisely at the moment where survival — not just betterment — is at stake.
Such ideas can make the task of integrating, or reintegrating, environmental and human realities sound far away and abstract. But it’s not.
The most redemptive and encouraging commonality of all the people I’ve encountered who have made a truly evolutionary leap is that they have come to love the very local, very particular places they inhabit. They were drawn into environmentalism by suddenly seeing beauty they had taken for granted; by practical concern for illness and health in neighborhood children; by imagining possibilities for the survival of indigenous flora and fauna, the creation of jobs, the sustainability of regional farms. The catchword of many of our most ingenious solutions to this most planetary of crises is “local” — local food, local economies. Ellen Davis and Wendell Berry illuminate this with poetic, biblical wisdom, each in their way reminding us that the health of our larger ecosystem is linked to knowing ourselves as creatures — “placed creatures.”
There is so much in my most recent conversation about all of this with Bill McKibben that will frame and deepen my sense of the nature and meaning of climate change moving forward. Among them is an exceedingly helpful four minutes, a brief history of climate change that we’re making available as a separate podcast. But what has stayed with me most of all, I think, is a stunning equation he is ready to make after two decades of immersion in the scientific, cultural, and economic meaning of our ecological present. He points out that cheap fossil fuels have allowed us to become more privatized, less in need of our neighbor, than ever in human history. And he says that in almost every instance, what is good for the environment is good for human community. The appeal of the farmers market is not just its environmental and economic value but the drama, the organic nature, of human contact.
I also gained a certain bracing historical perspective from my conversation with Bill McKibben. He and I were both born in 1960. He was waking up to the environment in years in which I was in divided Berlin, on the front lines of what felt like the great strategic and moral battle of that age. He published The End of Nature in 1989, the year the Berlin Wall fell. And as I learned from that book, the science of climate change had already begun to emerge at the height of the Cold War. In 1957, two scientists at the Scripps Institution described their findings that humanity initiated an unprecedented “geophysical experiment” that it might not survive.
So I’ve been chewing on this thought lately: If humanity is around to write history in a century or two, what was happening with the climate in 1989 may dwarf what we perceived as the great geopolitical dramas of that time. Living through the fall of the wall and the reunification of Europe emboldened my sense that there is always more to reality than we can see and more change possible than we can begin to imagine. I draw caution as well as hope from the fact that history tends to surprise us. And I draw caution as well as hope from the knowledge that humanity often surprises itself on the edge of survival.
I Recommend Reading:
The End of Nature
by Bill McKibben
This was the first book to introduce the notion and science of climate change to a non-scientific audience. It is passionately and beautifully written. And while Bill McKibben’s updated introduction in recent printings adds relevant new knowledge, it also highlights just how prescient and powerful the original book remains.
So, Maggie Thatcher, his boss, also rejected Christopher Monckton’s preposterous claims against the science of climate change?
It’s clear Christopher Monckton doesn’t know . . . much of value.
Sorta disappointed Peter Sinclair didn’t go after Monckton’s preposterous insults of Jackie Kennedy and Rachel Carson, but there’s only so much debunking one can do in a limited period of time, and so much of Monckton’s work requires debunking, even cries out for debunking.
Is there anything Monckton claims which is not hoax?
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).
Coastal-Change and Glaciological Map of the Palmer Land Area, Antarctica: 1947—2009
By Jane G. Ferrigno,1 Alison J. Cook,2 Amy M. Mathie,3 Richard S. Williams, Jr.,4 Charles Swithinbank,5 Kevin M. Foley,1 Adrian J. Fox,2 Janet W. Thomson,6 and Jörn Sievers
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.
Actual observations of the world show global warming. Time-lapse photos of the destruction of the Columbia Glacier, in Alaska, by James Balog, should make any person start wondering how to control warming processes.

This remarkable image sequence captures a series of massive calving events at Columbia Glacier near Valdez, Alaska. Composed of 436 frames taken between May and September of 2007, it shows the glacier rapidly retreating by about half a mile (1.6 kilometers), a volume loss of some 0.4 cubic miles (1.67 cubic kilometers) of ice or 400 billion gallons (1.5 trillion liters) of water.
The time-lapse was taken as part of the ongoing Extreme Ice Survey (EIS), an ambitious project to capture global warming-induced glacial retreat in the act. Beginning in December 2006, photographer James Balog and his colleagues set up 26 solar-powered cameras at glaciers in Greenland, Iceland, Alaska, the Alps, and the Rocky Mountains. Each unit will take a photograph every daylight hour until fall 2009.
In 2008, Balog’s team began to return to each of the camera sites to collect images. In the end, they will have more than 300,000 images to analyze and stitch together to produce more dramatic videos like this one.
This kind of multiyear effort, says Balog, is necessary to “radically alter public perception of the global warming issue.”
