Not long after the first Earth Day in April 1970, a Los Angeles aerospace engineer as engineers are wont to do saw a problem and came up with a solution to fix it. The problem Jack Nilles saw in his daily drive to the office was bumper to bumper traffic and bad air quality. His solution: substituting telecommunications for commute induced transportation demand by establishing satellite offices in “bedroom communities” where people lived to avoid the trip to centralized commuter offices. The environmental benefit of the solution Nilles proposed nearly five decades ago takes on increased urgency with the publication of a report issued today by the Intergovernmental Panel on Climate Change warning of rapidly accelerating global warming.

Absent aggressive action, many effects once expected only several decades in the future will arrive by 2040, and at the lower temperature, the report shows. “It’s telling us we need to reverse emissions trends and turn the world economy on a dime,” said Myles Allen, an Oxford University climate scientist and an author of the report.

To prevent 2.7 degrees of warming, the report said, greenhouse pollution must be reduced by 45 percent from 2010 levels by 2030, and 100 percent by 2050.

Turning the global economy on a dime is challenging to say the least. Cutting motor vehicle emissions associated with commuting is one measure that could be implemented relatively quickly, especially considering today’s information and communications technology is far more advanced than when Nilles first came up with his idea in the early 1970s, thanks to the proliferation of Internet protocol-based telecommunications.
