Scientists said the study does not contradict an earlier report showing that within the “Lower 48″ part of the United States, there has been no evidence of a warming trend over the last century. The 1987 study showed that the average temperature in the lower United States had fluctuated around a fairly stable century-long average of 52.5 degrees. Climatologists say the area, occupying 1.5% of the Earth’s surface, is too small to be representative of world trends.

Scientists said the study does not contradict an earlier report showing that within the “Lower 48″ part of the United States, there has been no evidence of a warming trend over the last century up to 1987. That study showed that the average temperature in the lower United States has fluctuated around a fairly stable century-long average of 52.5 degrees F (11.38 C). Climatologists say the area, occupying 1.5% of the Earth’s surface, is too small to be representative of world trends.

Contiguous US land area is 8, 080, 464 km2  compared with Australia at 7, 692, 024 km2. Sixth and seventh in order of the world’s land mass.

By comparison, the British office and the University of East Anglia Climatic Research Unit, the world’s oldest, most comprehensive center for global climate analysis, collected data from 1,000 weather stations on land and sea, around the world and found that the average year-round air temperature of the entire Earth in 1988 was 0.61 degrees higher than the average of 59 degrees for the period 1950-79. (15.33 degrees Celsius) NASA below, in the same period recorded a temperature of 15.44 degrees Celsius.  A difference of more that four degrees Celsius between US and the world temperature in the same period!!
