It is not uncommon to read that ice cores from the polar regions contain records of climatic change from the distant past.Research teams from the United States, the Soviet Union, Denmark, and France have bored holes over a mile deep into the ice near the poles and removed samples for analysis in their laboratories.Scientists can study Earth’s climate as far back as 800,000 years by drilling core samples from deep underneath the ice sheets of Greenland and Antarctica.Detailed information on air temperature and CO2 levels is trapped in these specimens.Current polar records show an intimate connection between atmospheric carbon dioxide and temperature in the natural world.In essence, when one goes up, the other one follows.If you're seeing this message, it means we're having trouble loading external resources on our website.If you're behind a web filter, please make sure that the domains *.and *.are unblocked.
was stable over the last millennium until the early 19th century. isotopic data) confirm that the increase must be due to emissions of CO from fossil fuel usage and deforestation.
Aside from the fascination with salvaging several vintage aircraft for parts and movie rights, the fact that these aircraft were buried so deeply in such a short time focuses attention on the time scales used to estimate the chronologies of ice.
If the aircraft were buried under about 250 feet of ice and snow in about 50 years, this means the ice sheet has been accumulating at an average rate of five feet per year.
In an Antarctic core (Law Dome) with a very high snowfall rate, it has been possible to measure concentrations in air from as recently as the 1980s that is already enclosed in bubbles within the ice.
Comparison with measurements made at South Pole station show that the ice core acts as a faithful recorder of atmospheric concentrations (see Fig.
An alternative model of recent glacier formation following the Flood described in Genesis will be suggested.
