5 Data-Rich Visuals That Shape My View of the World

I’ve always been attracted to data as a way of understanding the world a bit better.

True story: In 2006, when I was working at an ecolodge in Guatemala, I met a steady stream of travelers from all over the globe. I would carry The Economist’s Pocket World in Figures around as a cheat sheet to refer to every time I met people from a country I didn’t know enough about.

Since then, I’ve traded my dorky Pocket World in Figures for the Internet. Here are my favorite sites that take vast amounts of data about our planet and render it in dynamic, visual ways.



Want to see how heavily your country weighs in on … pretty much much any subject matter you’d like? Worldmapper’s 700+ maps resize territories based on datasets. The best place to start is the animations on the homepage. Then peruse Map Categories. I, of course, went straight to the tourism maps in the ‘Movement’ category.



For anyone who thinks in lines and curves set against x- and y-axes, Gapminder is for you. It shows huge amounts of country data and how it changes over time. If the bouncing, soaring colored dots aren’t making much sense at first, watch the videos of the site’s founder, Hans Rosling, who brings the graphs to life. His fact-based message is simple: the disparity between nations isn’t as bad as we may think, and our world is converging quickly. I love love love his positivity.

Map of Global Forest Change

A powerful new layer of the Google Earth Engine allows us to spy on forests all over the world. Google has applied algorithms and time-series data to quantify global forest change. It draws on NASA satellite imaging from the years 2000 through 2012. The resolution is high enough that you can zoom in on an area of interest — say, the Amazon — and find out where losses are the worst. Spoiler alert: global forest loss totaled 2.3 million square kilometers and gain 0.8 million square kilometers from 2000 to 2012, for a net loss of 1.5 million square kilometers. This is why trees need hugs too.

Global Warming: 1880-2012

In this animation of temperature data from 1884-2012, reds indicate temperatures higher than the average during a baseline period of 1951-1980, while blues indicate lower temperatures than the baseline average (Data source: NASA Goddard Institute for Space Studies). So, as we can see, the climate is changing. It’s very real, and it’s already happening. Deniers, why you gotta be like that? Climate defeatists, you’re not helping either. There’s still time to regulate, mitigate, and innovate. This is the greatest challenge we face in the 21st century.



Like the four other visuals on this list, Worldometers is fascinating because it’s dynamic, showing changes over time. Unlike the others on this list, however, its data doesn’t stop at the end of last year. Watch world statistics update themselves in real time. Most mind-bending meter for me: bicycle production this year is beating car production this year by more than double! Now, time to add this list to the 2,772,589 (and counting) blog posts written today.

Climate Change and Sustainable Tourism: A Point/Counterpoint

This article originally appeared in TIES Research Corner.  April 2011.

Airplane ContrailsIs climate change the biggest challenge to tourism sustainability in the 21st century?

The academic Journal of Sustainable Tourism started this year off with a debate about climate change and sustainable tourism. The first article, titled “Can sustainable tourism survive climate change?” is available for download in the public domain. Here, the author David Weaver kicks off the debate by positing that the climate change agenda may not be in the best interest of sustainable tourism. He gives seven issues with addressing climate change. They are:

1) Limited and imbalanced knowledge. Research on the relationship between climate change and tourism isn’t well-rounded enough yet to inform policy. For example, of all papers published on the topic, most projected the impact of climate change on tourism in affluent countries (namely ski destinations) while only 15% investigated tourism’s contribution to climate change. Less than 10% these studies have focused on impacts in less economically developed countries.

2) The unpredictability of future outcomes. Beyond 5 to 10 years into the future, uncertainty reigns. The number of variables and unpredictable situations make forecasting climate change unreliable for informing mitigation and adaptation strategy.

3) Accusation of dogmatic and uncomprmised engagement. Extremist media-driven agendas and even scandals among the IPCC (International Panel on Climate Control) such as “climategate” are undermining the neutrality and credibility of climate change science.

4) Fickle Markets. Tourism consumers in more affluent countries are aware of and concerned about climate change, but are unwilling to change their consuming patterns accordingly (i.e. fly less). He calls this “superficial environnmentalism” or “veneer environmentalism.” Even the most high-minded societies will therefore remain “mobility promiscuous.”

5) A house dividing? Adaption vs. Mitigation. Here, Weaver points out a potential conflict between adaptionists, whose “capitalism-compatible” response to climate change is formed by faith in technological solutions, and mitigationists whose commitment to reducing green house gases is less compatible with a pro-growth ethos.

6) Distracting from the intensity perspective. Attention to tourism sustainability is divided between the “volume perspective” that concerns itself with the global effects of travel-related carbon emissions, and the “intensity perspective” that concerns itself with destination-level impacts such as congestion. Destination planners pay lip-service to ideas like becoming “carbon neutral” rather than addressing more local intensity issues.

7) Lack of industry commitment. Tourism industry and hospitality management, with their superficial gestures such as the ubiquitous linen re-usage signs in hotels, also take on a “veneer environmentalism” that lacks any deep action or self-regulation.

As a final word, Weaver criticizes the effectiveness of allocating scarce resources to climate change, given the “lack of directly tangible consequences or clearly identifiable villains.” He calls for adaptation where it is strategic rather than empty claims about “carbon neutrality,” and for mitigation where it is a localized initiative to address intensity issues (such as habitat restoration) and may also have implications for climate change.

Daniel Scott answers Weaver’s argument in his response opinion piece “Why Sustainable Tourism Must Address Climate Change.” This paper is not available in the public domain. Scott addresses each of Weaver’s seven points, furthering a healthy and important discussion between the field’s leading experts. As an introduction, Scott affirms that climate change is indeed the biggest challenge to sustainable tourism in the 21st century. His counters to each of the seven points are as follows:

1) Limited and unbalanced knowledge. Scott agrees that there is a ‘knowledge gap’ on the subject, citing that only 1.7% of tourism papers in the past decade have addressed climate change. But he sees this as a call to research action rather than a reason for policy-makers not to implement. He’s optimistic that a critical mass of knowledge is indeed emerging to inform both the public and private sectors of tourism.

2) The unpredictability of future outcomes. Scott agrees that uncertainty is uncomfortable, but “cannot be allowed to paralyze decision-making in tourism.” Many industries, not just tourism, will be affected by climate change and are already working across disciplines to overcome its complexities so as to “think in terms of long-term sustainability.”

3) Accusations of dogmatic and uncompromised engagement. Here, Scott “clears the air” on climategate and other scandals that threaten the credibility of climate change science. He also notes that in the scientific community, there is little debate over the reality of anthropogenic climate change. 97%-98% support its tenets.

4) Fickle markets. Scott agrees with Weaver’s values-behavior gap of veneer environmentalists, and is “pessimistic that the norms of tourism mobility developed over the last 30–40 years will change through some groundswell of voluntary social change.” Emissions reduction and mitigation will have to come through government policy.

5) A house dividing? Adaptation vs. mitigation. Scott sees both adaptation and mitigation as inextricably linked to sustainable tourism development strategies, and that mitigation is indeed compatible with pro-growth capitalism as a “transformational opportunity.”

6) Distracting from the intensity perspective. Sustainable tourism development must account for the transport phase of tourism and its impact, not just tourism’s intensity impact on the destination. Climate change is simply added to the broader list of sustainability issues.

7) Lack of industry commitment. Scott agrees that carbon reduction aspirations among the airline sector has been purely aspirational, and destination government commitments to “carbon neutrality” as pure greenwash marketing. Yet, efforts toward a more sustainable tourism from within the industry itself should not be abandoned but rather developed and measured.

In his concluding thoughts, Scott contends that “how tourism responds to climate change is absolutely critical to sustainability of tourism” and that “climate change is a decision-making reality that will not go away” for tourism and every other sector. Reducing investment in climate change mitigation and adaptation would be a recipe for long-term failure. He reminds us that, according to the latest consensus, society should be preparing to adapt to +4◦C global warming.

Perhaps Weaver started the discussion as a sort of devil’s advocate, wanting it to be affirmed that climate change is the biggest challenge to tourism sustainability in the 21st century by presenting a hypothesis to the contrary. Scott rounded out the debate by providing that important affirmation.

Last Chance Tourism? Vanishing Destinations and Tourism’s Roles in Saving Them

This article originally appeared on The International Ecotourism Society blog Your Travel Choice. To see the original post, click here. December, 2010

Climate and travel are inherently linked. Climate affects our decisions about where to travel, and lately we’ve learned that the emissions of our travel (and our human activity in general) are affecting the climate. Climate change will change travel, and new winners and losers will emerge. For the past five years, headlines have claimed that climate change is actually popularizing certain at-risk destinations.

Travelers want to get there before it’s too late. “Last chance tourism,” as academia has agreed to call it, is on the rise. A study published in the September 2010 edition of the journal Current Issues in Tourism, titled “Last chance tourism: the boom, doom, and gloom of visiting vanishing tourism destinations” explains how “last chance tourism” is employed as a marketing strategy for certain destinations, especially in the Arctic.
