K., the Earth’s average temperature warmed by 1.4ºF (0.8ºC) between the 1850s and 2000s, mostly during 1911-19-1998: * Sources of uncertainty in surface temperature data involve “very incomplete” temperature records in the earlier years, “systematic changes in measurement methods,” “calculation and reporting errors,”       data adjustments that are performed when instruments are moved to different locations, instrument precision, instrument positioning, and missing documentation/raw data.  definitive assessment of uncertainties is impossible, because it is always possible that some unknown error has contaminated the data, and no quantitative allowance can be made for such unknowns. * Oceans constitute about 71% of the Earth’s surface. 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.  This data is combined with changes in air temperature over land areas to produce global averages.  contrasted water and air temperature changes in the tropical Pacific Ocean using three sources of measurements.One of these was a series of buoys, each containing thermometers located ten feet above the water and at one foot below the water.Certain bacteria, also referred to as chemoautotrophs, use carbon dioxide to synthesize the organic compounds they need. It occurs in more different forms than any other element in the periodic table.Let us trace the path of carbon as it constantly moves through various steps of the carbon cycle.Carbon is the fourth most abundant chemical element in the universe and forms the building blocks of the living world along with hydrogen and oxygen.The study found that water temperatures increased on average by 0.23ºF (0.13ºC) per decade between 19, while air temperatures cooled by 0.02 to 0.09ºF (0.01 to 0.06ºC) per decade during the same period. examined the locations of 1,007 of the 1,221 monitoring stations used to determine average surface temperature changes across the continental United States.
There is a constant exchange of carbon between the biotic and the abiotic world, thus forming a cycle which is called the carbon cycle.If your comment has been immediately deleted, congratulations, you are officially a troll.as “an increase in the average temperature of the Earth’s atmosphere,” either by “human industry and agriculture” or by natural causes like the Earth has “experienced numerous” times “through its history.” * Some writers use the phrases “global warming” and “climate change” to mean temperature changes strictly caused by human activity.   Other writers use adjectives such as “man-made” and “anthropogenic” to distinguish between human and non-human causes.  (“Anthropogenic” means “of human origin,” and “AGW” stands for “anthropogenic global warming.”) * Just Facts’ Standards of Credibility require the use of “language that is precise and unambiguous.” Hence, when human causes are stated or implied, this research uses terms like “man-made” and “human-induced.” * The greenhouse effect is a warming effect caused by certain gases that retain heat from sunlight. Without such gases, the average surface temperature of the Earth would be below freezing, and as explained by the , “life, as we know it, would not exist.” The global warming debate is centered upon whether added greenhouse gases released by human activity will overheat the Earth and cause harmful effects. * Human activities currently release about 37 billion metric tons of CO2 per year, which equates to about 5% of natural CO2 emissions.After two half lives, a quarter is left; after three half lives, only an eighth; after 10 half lives, less than a thousandth is left.Diamond is the hardest substance known, so its interior should be very resistant to contamination.
