People living on earth are responsible for global warming.

With this warning that an ancient enemy poses a real and present danger to the near and immediate future of civilization, let us return to the Younger Dryas and the possibility, after the first encounter 12,800 years ago, that the earth interacted for a second time with some large and dangerous comet fragments orbiting in the Taurid stream. On this hypothetical second occasion, however, the scenario proposed by the astronomers suggests that the primary impacts were not on land, or onto ice, but into the world’s oceans throwing up vast plumes of water vapour and creating a “greenhouse effect” that caused global warming rather than global cooling.

The paper cited scientific models predicting increases in global precipitation per degree of warming of as much as 2 percent but concluded that such an explanation still didn’t explain the heavy Denali snow.

The latest study, “Industrial-Age Doubling of Snow Accumulation in the Alaska Range Linked to Tropical Ocean Warming,” found that winter snowfall has risen by 117 percent in south-central Alaska and that summer snows increased by 49 percent in less than 200 years.

Many scientists think that pollution is the cause of global warming and the greenhouse effect.
Increase warming of global temperatures account as a major concern of Earth’s surroundings.

To briefly revisit , men have always committed vastly more violence than women, were the primary hunters, and almost . In general, the higher women’s status, the healthier the society was. The people of Africa stayed isolated hunter-gatherers to the present day. Their , with its click sounds shared with other African groups, such as the last full-time hunter-gatherers left in Africa, the , probably sounded like the language that the founder group left with and has since been lost beyond Africa. Genetic testing has demonstrated that the and related groups remained in Africa when that founder group left, and their geographic isolation and warlike ways . Genetic testing also traced the migration path to Australia, and found peoples that stopped along the way, as part of a coastal migration that and maybe . One reason why the coastal route was probably the first was that it was warm and relatively easy. Around 60 kya, the global climate warmed a little. It was about before it began oscillating toward .

The ecosystems may not have recovered from Olson’s Extinction of 270 mya, and at 260 mya came another mass extinction that is called the mid-Permian or extinction, or the , although a recent study found only one extinction event, in the mid-Capitanian. In the 1990s, the extinction was thought to result from falling sea levels. But the first of the two huge volcanic events coincided with the event, in . There can be several deadly outcomes of major volcanic events. As with an , massive volcanic events can block sunlight with the ash and create wintry conditions in the middle of summer. That alone can cause catastrophic conditions for life, but that is only one potential outcome of volcanism. What probably had far greater impact were the gases belched into the air. As oxygen levels crashed in the late Permian, there was also a huge carbon dioxide spike, as shown by , and the late-Permian volcanism is the near-unanimous choice as the primary reason. That would have helped create super-greenhouse conditions that perhaps came right on the heels of the volcanic winter. Not only would carbon dioxide vent from the mantle, as with all volcanism, but the late-Permian volcanism occurred beneath Ediacaran and Cambrian hydrocarbon deposits, which burned them and spewed even more carbon dioxide into the atmosphere. Not only that, great salt deposits from the Cambrian Period were also burned via the volcanism, which created hydrochloric acid clouds. Volcanoes also spew sulfur, which reacts with oxygen and water to form . The oceans around the volcanoes would have become acidic, and that fire-and-brimstone brew would have also showered the land. Not only that, but the warming initiated by the initial carbon dioxide spike could have then warmed up the oceans enough so that methane hydrates were liberated and create even more global warming. Such global warming apparently warmed the poles, which not only melted away the last ice caps and ended an ice age that had , but deciduous forests are in evidence at high latitudes. A 100-million-year Icehouse Earth period ended and a 200-million-year Greenhouse Earth period began, but the transition appears to have been chaotic, with wild swings in greenhouse gas levels and global temperatures. Warming the poles would have lessened the heat differential between the equator and poles and further diminished the lazy Panthalassic currents. The landlocked Paleo-Tethys and Tethys oceans, and perhaps even the Panthalassic Ocean, may have all become superheated and anoxic as the currents died. Huge also happened, which may have and led to ultraviolet light damage to land plants and animals. That was all on top of the oxygen crash. With the current state of research, all of the above events may have happened, in the greatest confluence of life-hostile conditions during the eon of complex life. A recent study suggests that the extinction event that ended the Permian may have lasted only 60,000 years or so. In 2001, a bolide event was proposed for the Permian extinction with great fanfare, but it does not appear to be related to the Permian extinction; the other dynamics would have been quite sufficient. The Permian extinction was the greatest catastrophe that Earth’s life experienced since the previous supercontinent existed in the .

The idea is not as far-fetched as it might seem, particularly when we remember that the Younger Dryas cataclysm was not a single event but an with two pronounced nodes of disaster – the first, 12,800 years ago, accompanied by a humungous flood and abrupt, extreme global cooling, the second, 11,600 years ago, again accompanied by another humungous flood and this time by abrupt, extreme global warming.
