i see that as in case of emergency break glass kind of thing. >> geoengineering is a last ditch option. some worry that is only going to encourage us to emit greenhouse gases the way we have. scientists warn tinkering with nature can have unforeseeable consequences. >> melanie has studied the global impacts of climate change. >> we need to be careful with geoengineering that the cure is not worse than the disease. we can indeed seed clouds and put particles to reflect sunlight. the problem with that kind of solar radiation management is that you have to keep going with it all the time, if we're continuing to emit carbon at the same time, we haven't gone to the root cause of the problem. >> because geoengineering has the potential to change the entire planet, fitzpatrick said there should be a global debate before any one nation intentionally alters the climate. >> the public needs to be engaged. there's questions about the governance of it. who will decide to deploy that, where will they decide to deploy it. will it cause climate changes and will they be irreversible. >> it doesn't add

but the truth is we only barely understand what geoengineering could do to the plan it and the skies that we all must share. >> and this report from jacob ward. could a city known for its beer become the new hollywood? millions who need assistance now. we appreciate you spending time with us tonight. >>> up next is the golden age of hollywood going golden but elsewhere. why l.a.'s mayor has declared a state of emergency for the entertainment industry there. next. >> finally tonight, you know it was a big night in hollywood as the stars gathered for the emmy awards but not to be out done. china's richest man hosted his own red carpet. carmona's eastern city quingao may be the hollywood. >> this is hollywood chinese style. the star power alone suggestions the coastal city of quingao may be the hollywood of china. >> my daughter ella. >> the dream of china's richest man, won jon lynn, hosting 20 sound stages, the world's first underwater studio and a chain of resort hotels among others, all to the tune of $8 billion, the biggest single investment in the film business. >> the cultural in

various geoengineering. practices that we could use to stabilise climate we don't have that research we have been we haven't done a need to test trials yet to see how it would work and the problem is the old being the only real laboratory we have is the earth itself and so it's kind of risky. trying to. figure out how. a given response and we might come up with a technological fix so to speak might one of my translate into we just don't don't have the knowledge to do that sort of thing then and the competence geoengineering it we already are geo engineering because we've overloaded the atmosphere with carbon that's experiment number one now we're going to layer other experiments geoengineering and it's almost like drugs this doctor gives you this drug this other nurse gives you that drug and you have these strange interactions how is it going to interact what we do know is that if you throw up these small tiny particles in the atmosphere that are similar to happens with volcanoes you can reflect sunlight ok

all others geoengineering let's just put titanic side in the upper atmosphere no problem like this if i take my car apart in my driveway and put it back together i can turn the switch and it'll run if i take a cow or part of my driveway and put it back together it's never going to mow again the earth you know james lovelock i think came out with this guy a hypothesis that the earth is a is a living organism and in fact he's now saying we've gone beyond the point of no return i'm curious both of you what your thoughts are on just that whole thing of the you know how do we alter our thinking what is the nature of the world how. blest if i could be human. as as i think about the climate deniers i would remind you that the flat earth society did not go out of business until nine hundred ninety two literally literally you know there was still a small pocket in california but they finally finally gave up the ghost and accept the fact that the earth might be ground. what was your question before i interrupted you the earth is a living organism your thoughts and perspective how do we change t

technical institutions, or institutions that emphasize or have a very strong presence in science take no geoengineering and math. i mention harvey mudd, colorado school of mines, south dakota school of mines, caltech, mit attend standard which a very glowers -- another brookings report shows that one in 10 jobs in u.s. economy, this is very interesting, our sub of bachelor degrees, stem jobs. these jobs have an average salary of $53,000 per year. pretty good. in dallas and milwaukee, 15% of the job listings were sub bachelor stem jobs. real-life example, in the news, edward snowden. you all know who edward snowden is. not recommend him for a trader of the year or two of the year. that's not my topic. just note he had no college degree. yet know high school degree and was getting paid $200,000 a year for his technical abilities. i should set the cement ago, in this pay scale, rankings where the schools with heavy stem focus, school with the highest in 2013 was harvey mudd. smaller meeting school in california. they earn about $2 million more in their lifetime than it he would've earned with just a high
