Sukihara carbon dating
Prior to instrumentally derived temperature records that began in the 1850s, knowledge of seasonal and regional-scale marine temperature changes at high latitudes is limited.
Thus at present, hemispheric Atlantic climatic patterns are deduced from multiproxy and instrumental networks using statistical (1, 2) and modeling (3) approaches.
In a closed room, fumes of burning wood and coal produces carbon monoxide which combines with hemoglobin reversibly and replaces oxygen, leading to hypoxemia.
Serbian mathematician Milutin Milankovitch had suggested the Earth's orbit - essentially is proximity to the sun - could explain why there were ice ages every 100,000 years.
But Lenton and is colleagues said the true drivers were temperature and greenhouse gases, with the Earth's orbit playing more of a bit role.
Taking 800,000 years of ice core data and putting it into a mathematical model, the researchers, writing in the journal Nature Climate Change on Monday, were able to demonstrate a correlation between the rising temperatures and a spike in greenhouse gas emissions across several ice ages."This gives a direct deduction from this past data that there is a strong effect of the temperature on concentrations on carbon dioxide and methane, in other words two major greenhouse gases," Tim Lenton, a co-author on the paper from the University of Exeter, told CBS News.
"That gives us a direct confirmation purely from the data that there is this positive feedback loop."The study also suggests alterations of the Earth's orbit of the sun - a key theory known as the Milankovitch cycles - didn't have nearly as much impact on the severity of ice ages as previously believed.
The Jaenschwalde power plant is one of the biggest single producers of CO2 gas in Europe.
