World Population Clock I wonder if that clock is really representative... rOZZ Music Pictures |

World Population Clock What about the hopeful news in my opening post? [edit] Found another article on the matter: http://www.slate.com/articles/technology/future_tense/2013/01/world_population_may_actually_start_declining_not_exploding.html (I do notice a strong oscillation from time to time) rOZZ Music Pictures |

World Population Clock So many different factors that play a role and that we should consider... rOZZ Music Pictures |

Global climate change, war, and population decline in recent human history Although scientists have warned of possible social perils resulting from climate change, the impacts of long-term climate change on social unrest and population collapse have not been quantitatively investigated. In this study, high-resolution paleo-climatic data have been used to explore at a macroscale the effects of climate change on the outbreak of war and population decline in the preindustrial era. We show that long-term fluctuations of war frequency and population changes followed the cycles of temperature change. Further analyses show that cooling impeded agricultural production, which brought about a series of serious social problems, including price inflation, then successively war outbreak, famine, and population decline successively. The findings suggest that worldwide and synchronistic war–peace, population, and price cycles in recent centuries have been driven mainly by long-term climate change. The findings also imply that social mechanisms that might mitigate the impact of climate change were not significantly effective during the study period. Climate change may thus have played a more important role and imposed a wider ranging effect on human civilization than has so far been suggested. Findings of this research may lend an additional dimension to the classic concepts of Malthusianism and Darwinism. rOZZ Music Pictures |

The rate of population increase may be declining but overall population growth is still with us. Unfortunately it happens in places where, for one reason or another, the land cannot support the additional burden much longer. And even if the population in places like India and China remains stable their demand to have the things that people here in the west have had now for almost two centuries is putting a lot of stress on the environment. It will be a long time before "green" technology can provide the needs of those great masses who aspire to have all the comforts that relatively few humans enjoy.

Further analyses show that cooling impeded agricultural production Indeed so for any disruption to the normal weather and climate conditions needed for agriculture. That comment may well be only for cooling. However, you can expect that to be similarly true for any adverse change in climate or extremes of weather. We are pushing both rapid change of climate and ever more frequent extreme weather with our industrial CO2 pollution...

No. It's about cooling. Yes, and as I have stated over several years here, cooling will generate much bigger problems, for society, than global warming would do.

... Warming, as history has shown, increases crop production, and has led to the Rise of Country's, Empires, and Cultures. And your examples for that are?... There is the local brief event for the shores of Greenland back in history. Your longer term examples are? And what happened for other regions at that time? Meanwhile, you ignore the historical demise of large well established civilizations that perished due to drought...

I still dont know why natural cycles are blamed on humans. Do you have proof that this cycle is not natural? And is that proof peer reviewed? Would this proof be availble to the world? Is it understood and accepted by everyone? The population has bottlenecked many times now, prove this one is a bottleneck. Must not conflict resolve by suggesting that someone should go sit on an ice pick... |

There is absolutely no proof of what the impact of our actions will be on global climate changes. Why? Because it has never happened before. All the doom and gloomers have are computer models. Who writes the software that predicts doom and gloom, the very same doom and gloomers. It is just possible that there is a built in bias in their computer models. It's not surprising. if you want to convince policy makers of an impending global disaster and you are using software you and your supporters have written it's almost a guarantee that the results will support your position and if at first they don't you just change the parameters. In the past the mini ice ages have caused set backs due to reduced food production. I haven't seen any statistics for times when the weather was warmer than usual but logic tells me if it is warmer and there is more CO2 in the atmosphere with more water vapor more plants are going to grow more quickly. Spending billions of dollars to try to preserve the status quo is a total waste of time and resources. But I still believe in cleaning up our act as much as possible, that just makes common sense. So we can live on a cleaner warmer planet. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

I have lived in NJ for a long time, there was a time when one could almost walk across the Hudson on the pollution. Now there is actually recreation in the pristine waters. |

The "Black Plague" - are you talking about the plague that ran through Europe in the 1300s, or another plague event?? Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

The 'Black Plague' ... really no more than the Flu I suggest you come out to California and play a while with some of my cousin squirrels and see if you agree that it is just the flu. http://www.globalpost.com/dispatch/news/science/wildlife-news/130726/squirrel-bubonic-plague-closes-angeles-national-forest-calif |

OK my turn to be anal, the plague is a bacterial infection the flu is a viral infection. |

OK my turn to be anal, the plague is a bacterial infection the flu is a viral infection. Similarly for a little detail here: The rise and fall of civilizations has been determined more by small shifts in climate and rainfall patterns than by human developments or politics... Hence the great concern now for the rapid forced climate change our industrial pollution is pushing...

The "Black Plague" - are you talking about the plague that ran through Europe in the 1300s, or another plague event?? I think you are getting two different events mixed up in your mind. It is very easy to do so, as the dates are so close together. First in the late 13th century and early 14th century there was the "Great Famine" - many crop failures, low rainfall and so on. This killed about half the population of Europe. Second, in the middle of the 14th century was the "Black Death", a disease carried by fleas, which in turn were carried by rats. This killed (and here estimates vary greatly) between a half and two thirds of the remaining population of Europe. Black Death (bubonic plague and other names) was endemic in Europe for another couple of hundred years, and indeed still rears its ugly head from time to time. The plague, or mass deaths, that you talk about are not recorded, indeed the period from about 950 through to about 1200 there was a cultural boom in Europe, not something that you would expect at a time of great hardship and death. It was of course the "Mediaeval Warming" period, where mean (Northern Hemisphere) temperatures rose, over two hundred years, by about 0.2C, a tenth of the 2C we have seen in the last hundred or so years.

All a question of cultural and financial environment?... Or of better education and personal security?... Large decrease in number of births The number of births in England and Wales fell in 2013 by the largest annual amount in nearly 40 years, official figures show. The Office for National Statistics said live births decreased from 729,674 to 698,512 in 2013, down 4.3% which is the biggest fall since 1975. The average age of mothers was 30 compared with 29.8 years in 2012. The "total fertility rate" - the number of children per woman - decreased from 1.94 to 1.85...
