We can't say for certain whether there'd be unanticipated side effects producing consequences we might not expect logan had missed. nonetheless researchers around the world are working on ways to technically manipulate the climate such interventions in the chemical and physical processes of the earth are known as climate engineering. andreea socially is from the geo mar how health center for ocean research in kyoto studies what effects such tinkering could have on my phone our planet. we distinguish between two methods of climate engineering the first. tries to address the symptom namely clima...

What's your off. technically speaking some of the intervention methods are already feasible today such as reducing solar radiation just like a volcanic eruption. we could inject the same amount of sulfur into the stratosphere as was a minute during the one thousand nine hundred one eruption of mount pinatubo in the philippines it took a year for it to disperse and for temperatures to rise again. you know to all that so i don't have to go eruption led to a cooling of the earth sulfur aerosols were distributed around the globe and the average global temperature fell by half a degree so that's wh...

To use final disposal site so it's technically possible but do we want to avoid more people except as a selfish course it's. underground c o two storage has raised fears of earthquakes and potential problems with groundwater. for now at least the effects remain hard to predict. policymakers have been wary of climate engineering whether and when it might be implemented is unclear but what is clear is that if nothing is done global warming will continue with melting ice at the poles and increasing desertification. global warming is increasing dramatically and we don't see any scenario where we c...

Into something called climate engineering or geoengineering, which is a way to manipulate the climate to mitigate the effects of global warming. they're looking at a planet they think is warming up and they think maybe this might pose a national security threat in the form of exacerbating water shortages or causing more regional instabilities like places like darfur. they want to find ways of mitigating climate change and they're investigating are there possible ways of doing that. >>steve: okay. do you see a connection there between the c.i.a. and the sky? >> well, you know, i think that it's...

A carbon dioxide for photosynthesis after they've bloomed the microorganisms sink down into the deep sea disposing of the c o two they've incorporated. nutrients used for fertilization could be dispersed around the world by a major ocean currents that would increase plumes of phytoplankton and algae. but here too the potential for c o two capture ten percent at most and what effect it would have on the ecosystem is unclear and possibly risky. perience with climate engineering has been gathered on land as well in switzerland giant pump that silla these have been sucking c o two. ackley out of t...
