As explained by the LIST agency, the National Oceanic and Atmospheric Administration (NOAA), there are 7 indicators that would be expected to increase in a warming world (and they are), and 3 indicators would be expected to decrease (and they are): Ten indicators for a warming world, past Decade Warmest on Record According to Scientists in 48 Countries, NOAA, July 28, 2010 What is the Greenhouse Effect? The term greenhouse is used in conjunction with the phenomenon known as the greenhouse effect. Energy from the sun drives the earth’s weather and climate, and heats the earth’s surface; * In turn, the earth radiates energy sack into space; * Some atmospheric gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse; * These gases are therefore known as greenhouse gases; * The greenhouse effect is the rise in temperature on Earth as certain gases in the atmosphere trap energy.

Six main greenhouse gases are carbon dioxide (ICC), methane (CHI) (which is 20 times as potent a greenhouse gas as carbon dioxide) and nitrous oxide (NON), plus three fluorinated industrial gases: hydro fluorocarbons (Huffs), per larboards (Pecs) and sulfur hexafluoride (SF). Water vapor is also considered a greenhouse gas.

This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric ICC has increased since the Industrial Revolution: The above covers hundreds of thousands of years and shows how atmospheric ICC levels have dramatically increased in recent years. If we “zoom” in on just the past 250 years, we see the following: Anna’s Goddard Institute of Space Studies (GIGS) tracks atmospheric global temperature climate trends.

As environmental engineer, D Kelly Today explains: ‘To facilitate assessments of long term trends, climatologists compare the mean for a base period with the annual mean. Differences between the annual mean and baseline mean are called anomalies. GIGS uses the 1951 – 1980 period for their baseline period. They use the difference between the annual mean and the baseline mean to determine the global temperature anomaly for the year. Today produced a chart showing global temperature anomalies be;en 1800 and 2006 using data from NASA.
