Climate Crisis: Visualizing the Effects of Climate Change

future-summer-heat-20140709-001Climate Change means more than just on average hotter temperatures year round. There are also numerous consequences for sea levels, glaciers, weather patterns, weather stability, crop growth, fisheries, wildlife, forest fires, disease, parasites, rivers and fresh water tables. Explaining it can be a challenge, which is why visual tools like tables, maps and charts are so very useful.

Unfortunately, these too can seem bland and technocratic, and fail to capture the true extent and critical nature of Climate Change. Luckily, this past summer, a season that has been marked by uncharacteristically cool and hot temperatures, two particularly useful visual aids have been produced that seek to remedy this. By combining data-driven predictions with aids that are both personal and global in outlook, they bring the consequences of Climate Change home.

1001-blistering-summersThe first is known as 1001 Blistering Future Summers, a tool produced by the Princeton-based research and journalist organization Climate Central. This interactive map illustrates much hotter summers will become by the end of the century if nothing is done to stem global warming. Users simply type in the name of their hometown and the map compares current temperatures in their town to how high they will be and finds the geographic equivalent.

On average, according to Climate Central, daytime summer temperatures will be 4 to 6° Celsius (7 to 10° Fahrenheit) warmer across U.S. cities. That translates to most cities in the U.S. feeling like Florida or Texas feel in the summer today. For example, in the future, Boston will feel like North Miami Beach. And Las Vegas, where temperatures are projected to an average of 111 degrees, will feel more like Saudi Arabia.

dynamics_ccAs you can imagine, changes like these will have drastic effects that go far beyond scorching summers and inflated AC bills. Furthermore, when one considers the changes in a global context, and they will be disproportionately felt, they become even more disconcerting. And that is where the series of maps, collectively known as the “human dynamics of climate change”, come into play.

Developed by the U.K. Met Office (the official British weather forecast service) with the U.K. Foreign Office and several universities, they start with a “present-day” picture map – which shows trade in various commodities (wheat, maize, etc), important areas for fishing, routes for shipping and air freight, and regions with high degrees of water stress and political fragility.

dynamics_ccwThen the maps get into specific issues, based on climate forecasts for 2100 that assume that nothing will be done to stop global warming. You can see, for example, how higher temperatures could increase demand for irrigation water; how parts of the world could see increases and decreases in water run-off into rivers; how different areas are set for more flooding; and how the warmest days in Europe, parts of Asia, and North America are projected to be 6°C warmer.

The poster also has summaries for each region of the world. North Africa, for instance, “is projected to see some of the largest increases in the number of drought days and decreases in average annual water run-off.” North America, meanwhile, is forecast to see an increase in the number of drought days, increasing temperatures on its warmest days, and, depending on the region, both increases and decreases in river flooding.

climate-changeThe overall impression is one of flux, with changing temperatures also resulting in vast changes to systems that human beings heavily rely on. This is the most frightening aspect of Climate Change, since it will mean that governments around the world will be forced to cooperate extensively to adapt to changes and make do with less. And in most cases, the odds of this aren’t good.

For instance,the Indu River, a major waterway that provides Pakistan and India with extensive irrigation, originates in Pakistan. Should this country choose to board the river to get more use out of its waters, India would certainly attempt to intervene to prevent the loss of precious water flowing to their farmers down river. This scenario would very easily escalate into full-scale war, with nuclear arsenals coming into play.

Should water from this river prove scarcer in the future, control and repression surrounding its source is likely to increase. And when one considers that the Arab Spring was in large part motivated by food price spikes in 2010 – itself the result of Climate Change – the potential for incendiary action becomes increasingly clear.

And Europe is also likely experience significant changes due to the melting of the Greenland’s glaciers. With runoff from these glaciers bleeding into the North Atlantic, the Gulf Stream will be disrupted, resulting in Europe experiencing a string of very cold winters and dry summers. This in turn is likely to have a drastic effect on Europe’s food production, with predictable social and economic consequences.

Getting people to understand this is difficult, since most crises don’t seem real until they are upon us. However, the more we can drive home the consequences by putting into a personal, relatable format – not to mention a big-picture format – the more we can expect people to make informed choices and changes.

The Future…

A recent article from The Futurist concerning trends in the coming decade got me thinking… If we can expect major shifts in the technological and economic landscape, but at the same time be experiencing worries about climate change and resource shortages, what will the future look like? Two competing forces are warring for possession of our future; which one will win?

To hear Singularitarians and Futurists tell it, in the not-too-distant future we will be capable of downloading our consciousness and merging our brains with machine technology. At about the same time, we’re likely to perfect nanobots that will be capable of altering matter at the atomic level. We will be living in a post-mortal, post-scarcity future where just about anything is possible and we will be able to colonize the Solar System and beyond.

But to hear environmentalists and crisis planners tell it, we will be looking at a worldwide shortage of basic commodities and food due to climate change. The world’s breadbaskets, like the American Midwest, Canada’s Prairiers, and the Russian Steppe, will suffer from repeated droughts, putting a strain on food production and food prices. Places that are already hard pressed to feed their growing populations, like China and India, will be even harder pressed. Many countries in the mid-latitudes that are already suffering from instability due to lack of irrigation and hunger – Pakistan, North Africa, the Middle East, Saharan Africa – will become even more unstable.

Polar ice regions will continue to melt, wreaking havoc with the Gulf Stream and forcing Europe to experience freezing winters and their own crop failures. And to top if off, tropical regions will suffer from increased tropical storm activity and flooding. This will be create a massive refugee crisis, where up to 25% of the world’s population will try to shift north and south to occupy the cooler climes and more developed parts of the world. And this, of course, will lead to all kinds of political upheaval and incidents as armed forces are called out to keep them away.

Makes you wonder…

To hear the future characterized in such dystopian and utopian terms is nothing new. But at this juncture, it now seems like both of these visions are closer to coming true than ever before. With the unprecedented growth in computing, information technology, and biology, we could very well be making DNA based computers and AI’s in a few decades. But the climate crisis is already happening, with record heat, terrible wildfires, tropical storms and food shortages already gripping the world. Two tidal waves are rising and heading on a collision course, both threatening to sweep humanity up in their wake. Which will prove successful, or will one come first, rendering the other completely ineffective?

Hard to say, in the meantime, check out the article. It proves to be an interesting read!
