Plants, both on land and in the oceans, continually absorb and release large amounts of carbon dioxide. Natural processes absorb the equivalent of all natural emissions plus about 57% of man-made emissions, leaving an additional 16 billion metric tons of CO2 in the atmosphere each year.  * A 2001 ClimateGate email states: Look at the instrumental record.  Book: Encyclopedia of Paleoclimatology and Ancient Environments.  This is the most geographically extensive network of sites operated by any laboratory and it is important to note that the calibration scale it uses has changed since the TAR [IPCC’s Third Annual Report] (Dlugokencky et al. Since O2 is a well-mixed gas and its temperature is that of the atmosphere in which it is embedded, the intensity of these emissions is able to characterize the bulk layer atmospheric temperature.  * This picture shows two U. ” It is also: the “most important anthropogenic” greenhouse gas and “contributes more” to the greenhouse effect than “any other gas” released by human activity.
Water vapour: The main natural greenhouse gas is water vapour.  (“Anthropogenic” means “of human origin,” and “AGW” stands for “anthropogenic global warming. The highest point above sea level in the entire nation of Tuvalu is only 4 meters. This would be a high end estimate of the human impact. ” “Lower Troposphere … These temperatures are for the lowest 8 km (5 miles) of the atmosphere. A “tropical storm” is a cyclone with winds ranging from 39 to 73 miles per hour. Data from these instruments is used to calculate the average temperatures of different layers of the Earth’s atmosphere. , 1998), the pre-industrial global value for CH4 from 1700 to 1800 was 715 ± 4 ppb (it was also 715 ± 4 ppb in 1750), thus providing the reference level for the RF calculation.
 In the January 1959 issue of Life magazine, the commander of this mission described the ice cover by stating: We repeatedly found open water where we could surface f dating site related 35 txt 35. 5 billion tons of anthropogenic CO2 emitted per year / 770 billion tons of natural CO2 emitted per year = 4. Accessed July 18, 2011 at “ Why do some estimates of CO2 emissions seem to be about 3 1/2 times as large as others.. ” – Daily Kos “Melting Polar Ice Cap Created A Lake On Top Of The World” – “At some point, temperatures at the North Pole got balmy enough to create a lake where there should be a brick of frozen ice.  Changes in air temperature over the world’s oceans are typically based on measurements of water temperature at depths varying from less than 3 feet to more than 49 feet. ”  Book: Carbon Dioxide Capture for Storage in Deep Geologic Formations – Results from the CO2 Capture Project, Volume 1. ” * In the June 13, 1963 issue of New Scientist, a U.  writing, “I feel rather uncomfortable about using not only unpublished but also unreviewed material as the backbone of our conclusions (or any conclusions).
