  The Ultimate Global warming Dog Breeds Information Guide and Reference
Global warming theories attempt to account for the rise in average global temperatures since the late 19th century (0.6 ± 0.2°C) [1] [2] and assess the extent to which the effects are due to human causes.
The most common global warming theories attribute temperature increases to increases in the greenhouse effect caused primarily by anthropogenic (human-generated) carbon dioxide and to possible increases in solar activity.
Arrhenius' colleague Arvid Högbom was one of the first to study the carbon cycle.

 Acids and Bases: Free Encyclopedia Articles at Questia.com Online Library
There are three theories that identify a singular characteristic which defines an acid and a base: the Arrhenius theory, for which the Swedish chemist Svante Arrhenius was awarded the 1903 Nobel Prize in chemistry; the Brönsted-Lowry, or proton donor, theory, advanced in 1923; and the Lewis, or electron-pair, theory, which was also presented in 1923.
The Brönsted-Lowry theory, named for the Danish chemist Johannes Brönsted and the British chemist Thomas Lowry, provides a more general definition of acids and bases that can be used to deal both with solutions that contain no water and solutions that contain water.
The Lewis theory defines an acid as a compound that can accept a pair of electrons and a base as a compound that can donate a pair of electrons.

The observed warming of the Earth over the past 50 years appears to be at odds with the sceptics' theory that climate feedbacks will cancel out the warming.
Sceptics of global warming point to potential feedbacks that current models poorly understand, such as changes in vegetation and cloud cover, and suggest that these processes reduce the sensitivity of the climate to greenhouse gas forcing.
