Expert Voices: Oliver Wise, City of New Orleans Analytics Director on the power of open data

At the recent Data for Good Exchange, Oliver Wise, Analytics Director for C40 city New Orleans talked about how the city is using open data platforms to drive economic recovery post Katrina and enhance climate resiliency. Part of this effort included developing an app called “Blight Status,” which uses open data to track progress and results in reducing urban blight in the city.

In a video of his remarks, Oliver Wise noted the growing need for cities to leverage data to set priorities, deliver on targets and measure results – all to the benefit of urban citizens:

“I think also what we need is talent in government – and city government in particular – who know how to use that data to identify challenges that departments are having and then deliver some intervention to them that they’re going to use to help deliver better services to citizens.”

Earlier this year marked ten years since Hurricane Katrina devastated the coastal C40 city of New Orleans. Under the leadership of Mayor Mitch Landrieu, the city has undertaken significant efforts to enhance resilience against climate threats.

The lessons learned in New Orleans can apply to cities around the world, and here at C40 we are committed to transparency and accountability through open data. Indeed, our very own Seth Schultz, C40 Director of Research, Measurement & Planning also participated in the Data for Good Exchange, chairing a panel discussion on using data to solve city problems.

Could ‘The Day After Tomorrow’ happen?

A researcher has produced a scientific study of the climate scenario featured in the disaster movie ‘The Day After Tomorrow’. In the 2004 film, climate warming caused an abrupt collapse of the Atlantic meridional overturning circulation (AMOC), leading to catastrophic events such as tornadoes destroying Los Angeles, New York being flooded and the northern hemisphere freezing. Although the scientific credibility of the film drew criticism from climate scientists, the scenario of an abrupt collapse of the AMOC, as a consequence of anthropogenic greenhouse warming, was never assessed with a state-of-the-art climate model.Now scientists have found that, for a period of 20 years, the earth will cool instead of warm if global warming and a collapse of the AMOC occur simultaneously. —> Read More
