Coral Reefs In Grave Danger, Say Climate Simulations

sciencehabit writes "Nearly every coral reef could be dying by 2100 if current carbon dioxide emission trends continue, according to a new review of major climate models from around the world. The only way to maintain the current chemical environment in which reefs now live, the study suggests, would be to deeply cut emissions as soon as possible. It may even become necessary to actively remove carbon dioxide from the atmosphere, say with massive tree-planting efforts or machines."

    Alarmist much? The *current* coral reefs will die, but new ones will appear at locations where the CO2 level is currently too low for them.

    They are dying much faster than they are growing. It takes decades to centuries to grow a new coral reef from scratch. In the meantime the oceans bioversity would be decimated past the point of no return for many species.

    I like your open-minded approach - no, that's not sarcasm, I mean it. Yes, electricity from nuclear fission is cleaner overall than most other so-called baseload sources. It's still scary when something goes wrong - it doesn't matter about new designs, assurances, technological advances (which ARE impressive) - human fears are a factor, and must be dealt with, whether based on solid evidence, or FUD from greenpeace.
     
    I live off-grid using subsidised solar PV, and a petrol generator for backup when it's rainy. If I was really strict about appliance usage when the weather is less than ideal (e.g. turn off the kids' computers), we wouldn't need the generator very much at all. Let's put aside the environmental impact of manufacturing solar PV for the moment, and focus on whether it's possible to live off-grid with solar PV. Is it possible to continue a high-energy-consumption lifestyle with old-style incandescent light bulbs, air-conditioning, electric clothes dryers, electric dishwashers, electric coffee-makers, electric ovens and stovetops? No, it's not. Is it possible to minimise your consumption of fossil fuels and still enjoy life? Hells yeah. No aircon, occasional use of the clothes dryer run directly off the generator, wood-fired stove (also supplies hot water and heating), hand-wash dishes while listening to internet radio, 2-3 major appliances at any one time, e.g. 2 computers and a washing machine, or vacuum cleaner and washing machine, etc. It can work, if you want it to. Right now, I'm typing this on a laptop, on a sunday evening, listening to internet radio (B.B. King, if you're interested) via another laptop amplified through an old boombox, my daughter is watching some silly movie on Nickleodeon on a 55" LCD TV, sourced via a HD decoder from a satellite dish, my wife is playing minecraft on her laptop with an external 24" LCD screen, and my son is doing the facebook thing on his iPad - it's about 5:45pm, so house lights will be coming on soon - they're a mix of 24VDC halogen, and 240VAC CFL. All it takes is willpower, and (gratefully acknowledged) Govt subsidised PV - yes, I DO pay my taxes, BTW. Mind you, even if it the gear wasn't subsidised, it still would have been cheaper than getting the mains extended to my place.
     
    Not the right solution for everyone, obviously, but saying it can't be done is simply not true.
