Fossils Unlock the History of the North
By excavating bowhead whale fossils, research scientist Art Dyke...(is)...starting to understand the history of sea ice in the North. Art describes his work as "reconstructing the environmental conditions of the last 20,000 years." His efforts focus on the North, specifically on mapping the history of sea ice. This is a particularly difficult task since sea ice is geologically mute. Although it continually changes shape, expanding and retreating with the seasons, it leaves little to no record of its passage. Using fossils has proved to be an ingenious way to surmount this challenge...
The most common cause of death for the bowheads studied by Art and his colleagues was entrapment in the ice as it expanded in autumn. Because the whales followed the ice edge so closely, the location of their fossils indicates the extent to which the ice had previously retreated. By using radiocarbon dating, Art can determine the age of the fossils. Since fossils are only found where the ice edge once existed, their age tells Art how far the ice extended at a certain point in history.
Tracking and dating the progress of the bowhead whales entering the Northwest Passage from both the Atlantic and Pacific oceans also lets scientists determine when the passage was open during late summer and fall months. During an open period, whales from both oceans mixed freely and left their fossils throughout the length of the Passage...
Art and his colleagues have found a significant number of bowhead fossils scattered throughout the length of the Northwest Passage dating from approximately 10,000 years ago. This abundance of fossils coincides with the warmest part of the Holocene era. (The modern era that began 11,700 years ago.) At that time, it was approximately three degrees warmer than average temperatures in the mid-twentieth century. (That's what ended the ice age.)
According to Art, the current assumption is that, if the average temperature were to increase by three degrees, the passage would once more be open. Since the mid-1960s, the temperature has risen by one degree.See Note If this warming trend continues, then by the middle of this century, and for the first time in 3,000 years, the bowhead whales might be able to swim the Northwest Passage again.

Note: in 2008 that claim of one degree since 1960 has been retracted by government experts. It also turned out that six of the ten warmest periods in the 20th Century was in the 1930s. Now they claim we are entering a seven year cooling trend because of global warming. They also claimed after Katrina we were going to get slammed with record killer hurricanes because of global warming. Instead, we have had record low numbers of hurricanes since then. (They also blamed that on global warming.) That cooling trend was not in the computer models either. The simple fact is that the Northwest passage has been open several times in the past, including within recorded history. So unless the ancient Egyptians and Celts were driving SUVs 3000 years ago, we have to assume a natural event.
In fact according to the NASA Earth Observatory, "Without the Sun, the Earth would be no more than a frozen rock stranded in space. The Sun warms the Earth and makes life possible. Its energy generates clouds, cleanses our water, produces plants, keeps animals and humans warm, and drives ocean currents and thunderstorms. Despite the Sun's importance, scientists have only begun to study it with high precision in recent decades. Prior to 1979, in fact, astronomers and Earth scientists did not even have accurate data on the total amount of energy from the Sun that reaches the Earth's outermost atmosphere..."

Without even knowing solar radiation prior to 1979 just how could they make any correlation to anything prior to that? The sun is what drives the earth's climate. Yet even today NASA still says, "Due to technological barriers and a limited amount of data, however, scientist's understanding of the Sun-Earth system continues to be incomplete."
Science Daily (Mar. 21, 2003) Notes, "Since the late 1970s, the amount of solar radiation the sun emits, during times of quiet sunspot activity, has increased by nearly .05 percent per decade, according to a NASA funded study." They go into a big denial this has nothing to do with global warming that has occurred since 1850. If this has in effect remained steady, how many decades have gone by since 1850? From 1850 to 2000 is 15 times .05 = .75%.
To further quote the article, "This trend is important because, if sustained over many decades, it could cause significant climate change," said Richard Willson, a researcher affiliated with NASA's Goddard Institute for Space Studies and Columbia University's Earth Institute, New York. He is the lead author of the study recently published in Geophysical Research Letters. Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century..."
See http://www.sciencedaily.com/releases/2003/03/030321075236.htm and argue with NASA.
So let's add up some facts: Solar radiation measurements prior to 1979 had no real precision. Historical records show warming began in the 19th century and NASA measurements show increased solar radiation, which will certainly cause an increase in temperatures. That's what the science says according to NASA.
One further note is when solar radiation increases and warms the oceans out-gassing of carbon dioxide will occur.
