The relationship between technology and climate change is complex and multi-faceted. It was technology, in the form of fossil fuel combustion, that got us into this problem. Many uninformed politicians hold out hope that technology will miraculously save us in the future, so we can continue burning fossil fuels at our current rate. However, if we keep going along with such an attitude, risky geoengineering technologies may be required to keep the warming at a tolerable level.

However, we should never throw our hands in the air and give up, because we can always prevent the warming from getting worse. 2 C warming would be bad, but 3 or 4 C would be much worse, and 5 or 6 C would be devastating. We already possess many low-carbon, or even zero-carbon, forms of energy that could begin to replace the fossil fuel economy. The only thing missing is political will, and the only reason it’s missing, in my opinion, is that not enough people understand the magnitude and urgency of the problem.

Here is where technology comes in again – for purposes of communication. We live in an age of information and global interconnection, so ideas can travel at an unprecedented rate. It’s one thing for scientists to write an article about climate change and distribute it online, but there are many other, more engaging, forms of communication that harness today’s software and graphic technologies. Let’s look at a few recent examples.

Data clearly shows that the world is warming, but spreadsheets of temperature measurements are a little dry for public consumption. Graphs are better, but still cater to people with very specific kinds of intelligence. Since not everyone likes math, the climate team at NASA compressed all of their data into a 26-second video that shows changes in surface temperature anomalies (deviations from the average) from 1880 to 2010. The sudden warming over the past few decades even catches me by surprise.

Take a look – red is warm and blue is cool:

A more interactive visual expression of data comes from Penn State University. In this Flash application, you can play around with the amount of warming, latitude range, and type of crop, and see how yields change both with and without adaptation (changing farming practices to suit the warmer climate). Try it out here. A similar approach, where the user has control over the data selection, has been adopted by NOAA’s Climate Services website. Scroll down to “Climate Dashboard”, and you can compare temperature, carbon dioxide levels, energy from the sun, sea level, and Arctic sea ice on any timescale from 1880 to the present.

Even static images can be effective expressions of data. Take a look at this infographic, which examines the social dimensions of climate change. It does a great job of showing the problem we face: public understanding depends on media coverage, which doesn’t accurately reflect the scientific consensus. Click for a larger version:

Finally, a new computer game called Fate of the World allows you to try your hand at solving climate change. It adopts the same data and projections used by scientists to demonstrate to users what we can expect in the coming century, and how that changes based on our actions. Changing our lightbulbs and riding our bikes isn’t going to be enough, and, as PC Gamer discovered, even pulling out all the stops – nuclear power, a smart grid, cap-and-trade – doesn’t get us home free. You can buy the game for about $10 here (PC only, a Mac version is coming in April). I haven’t tried this game, but it looks pretty interesting – sort of like Civilization. Here is the trailer:

Take a look at these non-traditional forms of communication. Pass them along, and make your own if you’re so inclined. We need all the help we can get.
