Tim Kruger researches geoengineering: techniques to counteract climate change by deliberate, large-scale intervention in the earth system — either by reflecting sunlight back into space or by reducing the level of carbon dioxide in the atmosphere.

Why you should listen

While it is essential that we reduce global carbon emissions, that isn't going to be enough to avoid dangerous climate change. Research into proposed geoengineering techniques could prove vital in the fight to protect our planet. At the Oxford Geoengineering Programme, Tim Kruger aims to assess the range of proposed geoengineering techniques to determine which, if any, could be both technically feasible and benign environmentally, socially and ethically.

Kruger, a James Martin Fellow at the University of Oxford, is a co-author of "The Oxford Principles," a draft code of conduct for geoengineering research. It calls for geoengineering to be regulated as a public good, for public participation in decision-making and for disclosure of research and open publication of results.

In addition to his work at Oxford, Kruger is also CEO of Origen Power, which is developing a process that uses natural gas to generate electricity in a way that removes carbon dioxide from the atmosphere.

Planet, Protection: The talks of Session 6 of TED2017

April 26, 2017

Polar ice doesn’t care who’s in the White House. It just melts. In the sixth session of TED2017, hosted by TED’s Head Curator Chris Anderson, we hear blunt talk on climate change — taking a 30,000-foot view from the clouds and examining some market-based solutions for cleaning the planet. Below, recaps of the talks from Session 6, in […]
