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.”[1] * Some writers use the phrases “global warming” and “climate change” to mean temperature changes strictly caused by human activity.[2] [3] [4] Other writers use adjectives such as “man-made” and “anthropogenic” to distinguish between human and non-human causes.[5] [6] (“Anthropogenic” means “of human origin,”[7] and “AGW” stands for “anthropogenic global warming.”[8]) * 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.[9] 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.”[10] The global warming debate is centered upon whether added greenhouse gases released by human activity will overheat the Earth and cause harmful effects.[11] * Human activities currently release about 37 billion metric tons of CO2 per year, which equates to about 5% of natural CO2 emissions.

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.[36] † In permafrost regions, perennial snow accumulations trap air bubbles that leave records of past airborne CO2 concentrations,[38] [39] [40] and because regional CO2 concentrations vary by less than 10 parts per million over the Earth, these local records are globally representative.[41] [42] * Instruments located on satellites can measure certain properties of oxygen that vary with temperature.

The researchers seem to be associated with Catholic creationist groups, which have reported the conference earlier and more vocally than evangelical creationists.

One of these reports states that afterwards, “the abstract was removed from the conference website by two chairmen because they could not accept the findings.

Fellow contributor and consultant Dale Brosius has noted that, despite his many efforts, “carbon fiber is a material of last resort,” and then only as a means to improve fuel economy. According to the International Organization of Motor Vehicle Mfrs.

(OICA, Paris, France), the global automotive industry produced about 63 million passenger vehicles and 21 million commercial vehicles in 2012.

One of these was a series of buoys, each containing thermometers located ten feet above the water and at one foot below the water.

The recently introduced BMW is one of approximately 100 vehicle models manufactured around the world that feature at least some standard equipment (that is, not special-order items) made from carbon composites.

All IPCC definitions taken from Climate Change 2007: The Physical Science Basis. This post delves into the long-term carbon cycle that involves the interactions of the atmosphere with rocks and oceans over many millions of years.

Working Group I Contribution to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Annex I, Glossary, pp. Because of its length, I've broken it up into bookmarked sections for easy reference: to come back here click on 'back to contents' in each instance. Carbon dioxide and rock weathering: the chemistry Limitations to the precipitation of calcium carbonate: the Carbonate Compensation Depth The significance of weathering as a carbon-sink Deep weathering of rocks: an illustrated example from Mid-Wales, UK How breaking up minerals affects their weathering-rate: mountain-building as an accelerant Picking up signals of major weathering episodes in the geological record Weathering is a familiar process to us all.

It involves the chemical reactions between chemical compounds in the atmosphere and chemical compounds on the planet's surface.

When your car's exhaust pipe falls apart noisily, it is because the steel from which it was constructed has, over several years, reacted with oxygen and rainwater to form rust. But that's a relatively fast example involving a relatively unstable compound.
