In collaboration with researchers from the United States and Norway, scientists at Utrecht University have demonstrated how plate tectonics, the CO2 emissions from volcanoes particular the last 250 million years. The investigation shows, inter alia, that the earth has ever pumped twice as much CO2 into the atmosphere.
Because it is difficult to measure over a period of tens or hundreds of millions of years, CO2 emissions, scientists look to plate tectonics: this is the way to move tectonic plates or tectonic plates. If an oceanic plate under a different plate moves, limestone and fossil organic residues on the seabed blurred lines to be drawn into the interior of the earth. Within the sciences is called subduction. The shifting of tectonic plates leads to volcanism. In this way, the lime and organic residues come back into the atmosphere. The researchers measured the amount of subduction of the past 250 million years, and thus the total amount of CO2 emissions. This showed that there was once called blurred lines twice emissions. Therefore, the climate at the time of the dinosaurs was much warmer than our current climate. blurred lines
Type CT Scanner Using seismic tomography, a type of CT scanner, such as in a hospital, the scientists made a three-dimensional view of what is below the earth's surface. Through reconstructions researchers discovered spots on the earth's surface where the tectonic plates broke during blurred lines the collision blurred lines of continents and oceanic plates. The subduction then appears as a kind of scar on the scan. "The amount of gesubduceerde plate per unit of time is proportional to the amount of CO2 emissions. So we were able to determine how much CO2 was emitted over the past 250 million years, "says Douwe van der Meer, lead researcher.
Important greenhouse gas "The amount of volcanic CO2 emissions down on time scales of millions of years, how much CO2 is in the atmosphere. Because it is an important greenhouse gas, the climate blurred lines is strongly influenced by that. The new provisions of the CO2 emissions are crucial for determining the relationship between blurred lines CO2 and climate. Our new information from the deep Earth is independent of existing data on atmospheric CO2 levels from among fossils and confirm these data, "explains researcher Appy Sluis far.
Link between plate tectonics and volcanic CO2 emissions by Van der Meer are warned to be that the concept of plate tectonics is crucial in time for a variety of geological processes not be underestimated. blurred lines He says: "The rate of spread sheets dictates the height of mountains, the amount and location of ores, the height of the sea level and the magnetic field of the planet. In this study, we quantify for the first time the link between plate tectonics and volcanic CO2 emissions. That is a big step forward in understanding and predicting the behavior of the earth, and its consequences. "

"Therefore, the climate at the time of the dinosaurs was much warmer than our current climate." Yes. Since 1998, the amount of CO2 increased and the temperature is not even dropped blurred lines slightly. blurred lines
The ice cores from Antarctica in one million years. That's a lot, but too little for this study. blurred lines In addition, also with material from sediments atmospheric CO2 concentration blurred lines determined in a more distant past. Over many millions there is a perfect correlation blurred lines between CO2 levels and the large temperature changes that were taking. Now or in 15 years this relationship seems slightly less well. Is that a reason to say: No, there is no correlation between CO2 and temperature!
Furthermore, CO2 is indeed a building block for plants, blurred lines but it turns out that plants and other life still doing very well at a much lower CO2 levels of 180 ppm for example, while it is now 400 ppm and 280 ppm would be without human activities . Life, but not all, however thrives blurred lines well in a hot climate like during the Cretaceous dinosaurs, but the sea was well over 100m higher.
There is a very strong correlation between the amount blurred lines of CO2 in the atmosphere and of the average temperature. https://upload.wikimedia.org/wikipedia/en/thumb/6/63/Co2-temperature-plot.svg/720px-Co2-temperature-plot.svg.png But it is not 100% perfect as
