Back in 2005, the IPCC Working Group III Special Report on Carbon Dioxide Capture and Storage declared that the storage of naturally and industrially produced carbon dioxide in depleted hydrocarbon reservoirs and aquifers was considered an essential component of the strategy to combat the build-up of greenhouses gases in the atmosphere. It seemed like an easy solution, pump CO2 captured from nasty coal power plants and other high volume greenhouse gas sources back into the underground reservoirs that oil and gas has been extracted from. After all, those geologic formations held hydrocarbons for millions of years—now the pumped out oil fields are just sitting there, waiting to be put to use. That was until testing was done on rock from actual cap strata. It would appear that infusing rock layers with CO2-saturated aqueous fluid can alter the properties of caprock, leading to the escape of the sequestered carbon back into the environment.
Instrument data from the last 160 years indicate a general warming trend during that span of time. However, when this period is examined in the light of palaeoclimate reconstructions, the recent warming appears to be a part of more systematic fluctuations. Specifically, it is an expected warming period following the 200-year “Little Ice Age” cold period. Moreover, a new study of the natural variability of past climate, as seen from available proxy information, finds a synthesis between the Milankovitch cycles and Hurst–Kolmogorov (HK) stochastic dynamics—a result that shows multi-scale climate fluctuations cannot be described adequately by classical statistics.
The Appalachian mountains are seldom mentioned among the world's great mountain ranges. Consisting mostly of low gentle ridges, when compared with the snow-capped peaks of the Himalaya, Andes, or Alps many would hesitate to call them mountains at all. But they are a large and ancient range, stretching over 1500 miles along the eastern portion of North America. The time of their formation has been dated back to the Paleozoic, with major uprisings occurring 650 million years ago. Then, about 460 million years ago, during the Ordovician period, they were the site of one of the most violent volcanic outbursts in Earth's history. New research reveals that, following that bout of vulcanism, weathering of Appalachian rock may have triggered one of Earth's major ice ages—a relatively brief frigid period that ultimately killed two-thirds of all species on the planet.
Two of the terms bandied about by global warming alarmists are “unprecedented” and “irreversible.” It is troubling that scientists, who should know better, persist in using these terms even though the history of our planet clearly shows that neither term is accurate. Proof of this inaccuracy is obvious if we look back over the history of Earth—the Phanerozoic Eon in particular—taking the “Grand View” of historical climate change.
