Elimination of the big 3 (but not the only) GHG producing agricultural items (ruminant livestock, rice farming, and use of fertilizer) might not be enough, and even with just this, its EXTREMELY good odds that a good chunk of the >7 billion of us will start going hungry. Janneseti, Re: food waste... both your statement about food waste and my statement can be true at the same time. One does not preclude the other. Re: food waste recycling... About 35 years ago, we had food waste recycling. The dormitory kitchens and dining rooms at the university I went to recycled food waste. They sold it to a local pig farmer to feed his pigs. Why is it that a large number of people in the world today readily accept that anthropogenic GHG emissions from fossil fuel use is a bad thing, yet are all to ready to disregard the other half of anthropogenic GHG emissions (industry and agriculture -- agricultural GHG emissions being 33% of the total)? Did you even read the study I linked? Here is the link again. http://onlinelibrary.wiley.com/doi/10.1111/gcb.13340/epdf If the nations that agreed to the Paris accords (including much of the EU) are going to meet their agreed-upon reductions in *agricultural* GHG emissions, there are a lot of HARD choices to make. The cuts we already know how to make will only account for somewhere between 1/3rd and 1/5th of the total *agricultural* GHG emission cuts needed. If we HAD a magic wand (which we don't) and could totally eliminate fossil fuel use for production of electricity and for transportation, instantly... right now... today... it wouldn't solve the GHG-ACC problem.

I was merely stating that no one needs to go hungry for at least 80 years given the overproduction of food we have now and the expected population growth. Changing consumption patterns (diet and food waste) are only one of the challenges that we have have to deal with. To me this one seems not to be so complicated. From your article. Decreasing food loss and waste by 15% (estimates vary from 30 to 50% for lost or wasted food) would reduce emissions by 0.79 to 2.00 GtCO2e/yr (Stehfest et al., 2013). We cannot solve the GHG-ACC problem only mitigate it. ID: 1788800 · |

University of NSW breaks solar record Researchers at the University of NSW have utilised the light-trapping effects of a simple prism to dramatically boost the efficiency of solar cells http://www.smh.com.au/technology/sci-tech/unsw-researchers-break-solar-efficiency-record-for-unfocused-sunlight-20160517-gowsgx.html Who needs coal or Uranium now that the CSIRO have broken 2 records lately now Solar Cells and New rechargeable batteries NARRATION Around the world, the race has been on to develop a better battery than the current lithium configuration. And some of the top contenders are right here in Australia, such as Professor Thomas Maschmeyer. He believes he's just invented the battery that will change everything. Professor Thomas Maschmeyer This is our battery, it's based on zinc bromide. So, we've got the two electrodes here and what's called a coin cell, and then the key part is that we have a gel that we put on top of the electrode. NARRATION Zinc-bromine flow batteries exist already. They use a liquid to transport the changed particles, which has its advantages, but they're too big to fit in a phone or computer. Thomas' breakthrough idea was to take a zinc-bromine battery, but instead of a liquid, use a gel. So why a gel? Well, it's neither a liquid nor a solid, but you get the advantages of both. And that includes being able to move ions quickly, so you get rapid charging. Dr Jonica Newby So how quickly does it charge? Professor Thomas Maschmeyer We can get it down to just a few minutes. Dr Jonica Newby Really? So you're saying I could charge my phone in just a few minutes. Professor Thomas Maschmeyer In just a few minutes. And not just your phone, but also your car. NARRATION Already the batter is running at 90% efficiency, which is higher than in your mobile phone. It has a longer lifetime and zinc is cheaper than lithium. Dr Jonica Newby So if this becomes commercialised, it's cheaper, you can charge it faster, it lasts longer... Professor Thomas Maschmeyer And the gel is made out of a fire-retardant material. Dr Jonica Newby It's fire-retardant as well? Professor Thomas Maschmeyer That's correct. Dr Jonica Newby That's pretty impressive. Professor Thomas Maschmeyer Well, thank you very much. NARRATION But perhaps its biggest potential lies in the fact that being a gel, it's bendy. It won't crack. And that's what excites this industry. The potential is for flat pack zinc-bromine batteries to be included in the very fabric of buildings. Lendlease is just one of the big companies that's been inspired by Professor Maschmeyer's vision. Steve McCann It's very exciting, his work. Our vision is to create the best places. To do that, you have to continue to innovate. And we're thinking about things like working with Professor Maschmeyer to use prefabricated wall segments, for example, as, effectively, battery storage or power storage facilities. So imagine that in a large scale and the impact that will have on the emissions from the built space, which is a very significant impact on the environment. Dr Jonica Newby Wow. So the very walls of your future buildings would have, or could have, these kinds of batteries inside them. Steve McCann We don't think that's too far away, actually. Dr Jonica Newby Really?! Steve McCann We do. NARRATION Well, as we all know, the trip from benchtop to big business is not a smooth one, and who can predict if it's Professor Maschmeyer's battery that will make the trip.

Trump might be Mother Natures solution to warming. Maybe Trump should meet this wierd man... Or perhaps not... https://www.youtube.com/watch?v=EP5J3NFUjiw&feature=youtu.be The physics says yes. Controlled H-Bomb detonations [1] under the desert sands every year or two would hurl dust into the stratosphere and cool the planet, arresting abrupt warming. https://paulbeckwith.net/ ID: 1790544 · |

wtg, Britons, despite your Govt: http://www.theguardian.com/environment/2016/jun/07/solar-sets-british-record-for-may-producing-more-electricity-than-coal. Wow... So why is our government sabotaging renewables?! Norway is 100% renewables. Portugal is high on renewables and has run days at a time 100% renewable. Chile has periods of ZERO electricity costs due to renewables. Denmark and Holland EXPORT renewables electricity... So why is the UK languishing at about 25% renewables and our government subsidising pollution instead?! Corruption and lobbying at work?...

You could call it corruption and lobbying at work but thats how the energy market works. Norway is 100% renewables! No that's not true. It's about 65%. I don't know where your figures comes from but here is again what Eurostat says about renewables.  Whats most disturbing is the fact that France, Germany, Ireland, United Kingdom and the Netherlands are the countries that are still very far from the legally bindings targets for 2020. Another problem is that Eurostat stats only shows how much a country produce renewable energy. But not comparing the energy being imported from other countries when the energy prices are lower in countries with non-renewable energy. ID: 1794618 · |

So why is the UK languishing at about 25% renewables and our government subsidising pollution instead?! Might be explained by some of the following and population density. Hours of sunshine per year. London gets 20% less than Paris, and only 50% of Lyon. And you don't need reminding that London is in the South of England, it only gets worse further North. Four of the top five cloudiest Large Cities in Europe are British, ReykjavÃk is the other one. England not windy enough. ID: 1794624 · |

Four of the top five cloudiest Large Cities in Europe are British, ReykjavÃk is the other one. ReykjavÃk:) The only country in Europe that use 100% renewables are Iceland. However not solar energy for obvious reasons. England not windy enough. Thats a new one for me:) As you know winds are commonly coming from the Atlantic Ocean and hits the British Isles before it hits the Netherlands and the Scandinavian countries. Both the Netherlands and Denmark are countries that sometimes even can export the surplus energy from the wind. Perhaps if you include Scotland, Wales and Northern Ireland you could get more energy from wind:) ID: 1794632 · |

Wind takes the line of least resistance, so blowing from the west it finds a land gap and goes through it before meeting the coast of Europe, in the south up the channel and into the Netherlands and Denmark, and in the north, over the northern isles of Orkney and Shetland and hits Norway. At Sumburgh Head, Shetland, when there is a broad band of wind coming from the west, you can see the affect the wind causes on the seas that flow north up the North Sea and between Fair Isle and Shetland. They meet and form a ridge that can be bad enough to stop ships sailing east to west there. The ships coming from the west frequently take shelter in Quendale bay. When I lived up there the view from the kitchen window was over the bay. ID: 1794643 · |

You should know that we in the Scandinavian countries even have special clothings to protect us from the bad weather and heavy winds from the British Isles. Sou'wester or "Sydväst" as we call it because the wind comes from the south -west. https://en.wikipedia.org/wiki/Sou%27wester  ID: 1794649 · |

wtg, Britons, despite your Govt: http://www.theguardian.com/environment/2016/jun/07/solar-sets-british-record-for-may-producing-more-electricity-than-coal. Yep, there is far to much disingenuous twisting of the numbers. Is there still far too much 'sympathy' towards the presently expensively still-in-power fossils?... Is your chart out of date? What progress has there been since 2013?... Here's another quote that Norway is 100% on renewables for electricity: Why do they love electric cars in the Arctic Circle? ... But it is economic incentive as much as environmental concern that is fuelling the rise in green cars - Norway introduced a raft of generous subsidies to encourage people to go electric... ... It launched an aggressive tax policy towards high-polluting cars, while offering zero tax on zero-emission cars. This "polluter pays" policy brought the cost of an electric car into line with a conventionally powered one... ... The electricity being pumped into her car is free. Norway is fortunate enough to have close to 100% renewable and cheap hydro power production. According to the Norwegian Electric Vehicle Association, even if all three million cars on the country's roads were electric, they would suck up just 5-6% of the annual hydro power electricity production... And that article gives a good reminder that we really do need to have the polluters pay for cleaning up their pollution...

Norway is fortunate enough not to have a massive underclass that does not contribute to the resources of the Nation. Where do you think the subsidy comes from for electric cars: It comes from taxes on the individuals and favors a subset of their society. Too many of these types of actions will lead to another Greece Here in the US we favor many major constituencies and voting blocks--farmers, dairymen, sugar produces , Banks, ETC. We also have 47,000,000 on food stamps and 97,000,000 people who are no longer in the labor force. Additionally we have driven up the cost of gasoline and a good portion of our animal protein food due to Ethanol requirements. Electricity is not free--someone pays for the capital and consumable fuels used to produce it plus it is probably around only 40% efficient when it hits the plugin for the autos. Europe now has the cost per kilowatt hour exceeding 20 cents (US) . This equates to more than $58 per million BTU's. Admittedly electric cars have around a 2 to 1 advantage in efficiency versus the best diesels. Gasoline has a cost in the US right now of around $18 per million BTU's. Solar and wind are the most expensive form of energy creation--due to capital costs. My overall point is that Electric cars are not cheap to operate and that the consumer will ultimately pay for all of their real costs or else they have to rely on their neighbor to do so.

Norway is fortunate in many ways. They are also selling a lot of oil and gas to countries that doesn't have so much renewables.  About Eurostat. It takes two year to compile them and the graph was published may 2015 with the data from 2013 available back then. I find it hard to belive that Norway have gone from 65% to 100% in just a couple of years. I would like to see which countries that produce non-renewables and where it's consumed. That picture is totally different. ID: 1795039 · |

and 97,000,000 people who are no longer in the labor force. How is this number calculated, and which age groups are included? If you look at it logically and include the whole US Population, >300 Million. Then 97 Million is too small a number. The average person only works for about half their life. So the number, using whole population, should be closer to 150 Million. Even if you assume people work for 50 years then there should be over 110 Million not in the workforce. So therefore there has to be a different equation and/or different variables. ID: 1795043 · |
