... , it was during the 1800's that "greenhouse gasses- began to be studied and the idea of global warming was first introduced. But, during 1940 through the 1970's, worldwide cooling dampened scientific interest in the greenhouse effect. Some climatologists even predicted a new ice age. So in light of all this evidence, is global warming actually occurring? According to Accu-Weather, the world ... human-induced warming; more CO2 yields much higher surface temperatures; climate models are correct but are limited by computer technology; the climate will be more extreme; and, summers will be e...

... the middle 20th century, scientists and astronomers compiled data, which in turn led to numerous questions concerning the make-up of our solar system. The questions would remain unanswered until technology increased to a level which would help them explore their curiosities. In the mid 1950's, The Pioneer Space Program began revealing many answers to scientists. Over time this consisted of thirteen ... Wind and cosmic rays entering our portion of the Milky Way. In September of 1995, Pioneer 11 was at a distance of 4 billion miles from Earth and could no longer make scientific observatio...

... uncalculated amount of efforts to make observations throughout the history. The major ancient Greek philosophers Plato and Aristotle, populated their worldview based on subjective insights, but falling short of progressive scientific demands. The gradual emerging from Ptolemy's geocentric theory (100-170), to Tycho's circular geocentric orbits (1546-1601) to Copernicus heliocentric model (1473-1543) signified such changes. ... All three proposals induced century-long philosophical arguments and scientific analysis. Nowadays, heliocentric model is 99.9% publicly accepted so that it would ...

... . (Cunningham, 2000) In addition to these aerosol-producing events, variations of solar irradiance can account for some of the general warming trend seen in the past century. However, since the technology to perform these calculations has only been in existence for approximately twenty years, much of this pattern had to be extrapolated. From current satellite observations, sunspot blocking, facular emission, and ... the consequences that a warmer earth would bring about, research of this nature needs to be ongoing.
