NASA Study Acknowledges Solar Cycle, Not Man, Responsible for Past Warming

NASA Study Acknowledges Solar Cycle, Not Man, Responsible for Past Warming

www.dailytech.com

A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth's climate. The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution.

I always like cracking open the global warming chestnut, there is so much mindless and biased data it's not funny. But I do take notice when NASA comes out with a report like this. Certainly man can change the climate and it's been demonstrated many times, but is that the driving force behind current climate change?

I think it would be unwise to write the entire effect off as sunspot activity, simply because it behooves humanity to treat our planet well; and even if we only have a small impact on the temperature gain it may be enough to cause some pretty dramatic events. Needless to say this blog takes the route that teh report is using bad science when it tracks back to anthropogenic climate change.

Anyhow it's good to see some stand up science actually looking at the effect of the sun on the climate.

Man can change environments, but not the global climate, as the global climate is affected by many natural phenomenon such as the oceans, cloud formation, or lack of, the activity of the Sun, and even when the Solar System enters a new region of space.

NASA's main researcher Dr. Wilson has published papers in which he found evidence that the TSI of the Sun had been increasing in the 24 years of his studies, and the last year of his study was in 2002.

There have been other researchers who found the activity of the Sun in the 20th century was the highest in over 1,000 years, and despite all this and more, the Global Warming crowd keep trying to claim that CO2 is more important than the Sun, or any of the natural factors, and even all of them combined. Yet where is the evidence that CO2 causes such warming? only flawed computer models claim this, and that is no evidence.

Abstract
Evidence is presented that the recent worldwide land warming has occurred largely in response to a worldwide warming of the oceans rather than as a direct response to increasing greenhouse gases (GHGs) over land.

Atmospheric model simulations of the last half-century with prescribed observed ocean temperature changes, but without prescribed GHG changes, account for most of the land warming. The oceanic influence has occurred through hydrodynamic-radiative teleconnections, primarily by moistening and warming the air over land and increasing the downward longwave radiation at the surface. The oceans may themselves have warmed from a combination of natural and anthropogenic influences.

Well said, NASA is a government agency, after all.


There's no doubt that solar cycles have been responsible for climate change. Climate change events can be traced back thousands of years thanks to geological studies. However, there is also enormous evidence that we are not only experiencing a premature change for this cycle, but that the effects of the warming period are being compounded by man-made pollution. The changes we are seeing now, for example, are considerably more severe than those recorded during the Medieval Warming Period. They are also being brought on more suddenly, and most scientists attribute that to man-made environmental damage.

I understand many people believe 'global warming' is being used as a scam to increase government funding and power. I am one of them. However, to deny that human development and expansion is having an impact on our environment is utter foolishness. Things like carbon credit scams will not save our environment. It is up to all of us to make lifestyle changes in order to reverse the damage we are causing, as well as finding alternative energy sources.

Oh, and there have been times when NASA had inadvertently released some damning information that refuted the Global Warming claims, that is the claim that anthropogenic CO2 is the cause of the past warming.

Current warmth seems to be occurring nearly everywhere at the same time and is largest at high latitudes in the Northern Hemisphere. Over the last 50 years, the largest annual and seasonal warmings have occurred in Alaska, Siberia and the Antarctic Peninsula. Most ocean areas have warmed. Because these areas are remote and far away from major cities, it is clear to climatologists that the warming is not due to the influence of pollution from urban areas.

Oh boy...sorry but not true. There are "peer-reviewed" research papers from ALL over the world that show that the warming during the Medieval Warm period was worse than that of the late 20th century, or the beginning of the 21st century.


[edit on 4-6-2009 by ElectricUniverse]

NASA telling the truth?

Has hell just frozen over (pun intended)?

wZn

I do not accept that any person, scientist or otherwise, has enough data to render the global warming theory into the global warming law.

The cap and trade crowd are far too eager to use the tools of public relation, campaign-style promises, and populist rhetoric for me to accept it as gospel.

Is NASA lying? It matters not. They ALL lie.

Should I believe the liar who will get rich with his lie, or should I believe the liar who won't?

Anyone espousing the notion that economic policies and trading pollution rights will help our environment thinks too little of m y intelligence for me to take them seriously.

Should we live in harmony with our ecological environment..., of course - but what does my paying a third-party (middleman) trader have to do with it? In what way does trade limit pollution? All it does is enable the rich to exploit the environment (and thus us) with greater ease than those who are not rich.

Al ... Al .... Al ... you put too much faith in propaganda.

Would you care to back that up with sources?

Here are a couple which say that the MWP was less severe than the current climate change:

The various studies differ in methodology, and in the underlying paleoclimate proxy data utilized, but all reconstruct the same basic pattern of cool "Little Ice Age", warmer "Medieval Warm Period", and still warmer late 20th and 21st century temperatures.

In summary, it appears that the late 20th and early 21st centuries are likely the warmest period the Earth has seen in at least 1200 years.

As the US National Oceanographic and Atmospheric Administration (Noaa) puts it: "The idea of a global or hemispheric Mediaeval Warm Period that was warmer than today has turned out to be incorrect". Additionally, although the Arctic was warmer in the 1930s than in the following few decades, it is now warmer still.

The facts are all there, in graph form. You can say it was warmer, but if actually wasn't. Everyone's entitled to their opinion but you can't argue with facts.

reply to post by drwizardphd


Any idea why the graphs from 2007 only go to 2000? You'd expect the modern temperatures to carry on the 'hockey stick' trajectory getting steeper and steeper, based on that graph wouldn't you? Hmmm.... I wonder if the trend would look the same if they used up to date temperature measurements.

Thats more Illuminati bull.."Industrial Revolution".
As if man made effects cause planetary change.

UFOs are man made with Tesla parts.
How about the NASA.

Celestial Mechanics correlated planetary heating at the
glaciers for 600,000 years back in time and matched
the advances and retreats.

What do you think all those ice tubes were being used for
as they worked on glaciers for years.
They found out data the Illuminati didn't want and were fired.

All Ive got to state is the obvious, we release a ton of crap into the atmosphere. We ARE infact changing the enviroment and making it hotter. The only question seems to be at what rate. We are also destroying our ozone. The solar cycle could be adding to the effect making it hard to judge our affect on the atmosphere. However the solar cycle should not be used as a scapegoat. People would like to write it off as that so they dont have to deal with any blame though Im sure.

reply to post by Memysabu


Besides the ozone, I can't imagine it to be healthy sucking in all those nasty fumes.

Like really, many many studies link cancer, chronic bronchitis, pneumonia, and pretty much any other disease to pollution.

If it aint to save the planet, it's to save lives.

First of all a link from the BBC is no evidence at all, and I have posted many links several times in the past about this very same issue.

Abstract It is hypothesised that the Medieval Warm Period was preceded and followed by periods of moraine deposition associated with glacier expansion. Improvements in the methodology of radiocarbon calibration make it possible to convert radiocarbon ages to calendar dates with greater precision than was previously possible. Dating of organic material closely associated with moraines in many montane regions has reached the point where it is possible to survey available information concerning the timing of the medieval warm period. The results suggest that it was a global event occurring between about 900 and 1250 A.D., possibly interrupted by a minor readvance of ice between about 1050 and 1150 A.D.

20th Century Climate Not So Hot
Cambridge, MA - A review of more than 200 climate studies led by researchers at the Harvard-Smithsonian Center for Astrophysics has determined that the 20th century is neither the warmest century nor the century with the most extreme weather of the past 1000 years. The review also confirmed that the Medieval Warm Period of 800 to 1300 A.D. and the Little Ice Age of 1300 to 1900 A.D. were worldwide phenomena not limited to the European and North American continents. While 20th century temperatures are much higher than in the Little Ice Age period, many parts of the world show the medieval warmth to be greater than that of the 20th century.

Abstract

The Little Ice Age, from around 1300 to 1800, and medieval warming, from before 1000 to around 1300 in South Africa, are shown to be distinctive features of the regional climate of the last millennium. The proxy climate record has been constituted from oxygen and carbon isotope and colour density data obtained from a well-dated stalagmite derived from Cold Air Cave in the Makapansgat Valley.
The climate of the interior of South Africa was around 1oC cooler in the Little Ice Age and may have been over 3°C higher than at present during the extremes of the medieval warm period. It was variable throughout the millennium, but considerably more so during the warming of the eleventh to thirteenth centuries. Extreme events in the record show distinct teleconnections with similar events in other parts of the world, in both the northern and southern hemispheres. The lowest temperature events recorded during the Little Ice Age in South Africa are shown to be coeval with the Maunder and Sporer Minima in solar irradiance. The medieval warming is shown to have been coincided with the cosmogenic 10Be and 14C isotopic maxima recorded in tree rings elsewhere in the world during the Medieval Maximum in solar radiation.

Abstract
Data obtained from the low-elevation Khibiny Mountains (ca. 67–68°N; 33–34°E) on the Kola Peninsula, northwest Russia, indicate a period of exceptionally warm and dry conditions commenced at ca. AD 600 and was most pronounced between ca. AD 1000 and 1200. Warmer summer temperatures during this period (coeval with the ‘Medieval Warm Period’ observed in other parts of Europe) are evident in a 100–140 m upward shift in the pine (Pinus sylvestris L.) limit in the Khibiny Mountains. On average, the cellulose of pine trees that grew between ca. AD 1000 and 1300 is enriched by δ13C values of around 1‰ compared to the modern trees from the region, further suggesting warmer summer climate than at present. The Medieval Warm Period was also accompanied by a steady decline in avalanche activity and the resulting formation of soils on the current avalanche cones in the Khibiny Mountains, suggesting lower winter precipitation and thinner snow cover. Lower precipitation is also evident by currently submerged tree stumps dating to the medieval period that indicate lower lake levels on the Kola Peninsula. In the middle of the peninsula at about AD 1000, the level of small closed-basin lakes was 1 m lower than the modern time at some sites. Drier conditions may be attributable to decreased cyclonic activity. The medieval warm and dry episode was followed at ca. AD 1300 by the development of a colder climate with increased precipitation resulting in a decline in the alpine pine limits, increased avalanche activity, and higher lake levels. That phase corresponds to the modern aeolian episode reconstructed in subarctic Finland. Our results indicate that the Medieval Warm Period on the Kola Peninsula experienced notably warm and dry conditions. Hence, this period of warming extends to northwestern Russia as well as other parts of Europe.

Abstract The collected documentary records of the cultivation of citrus trees andBoehmeria nivea (a perennial herb) have been used to produce distribution maps of these plants for the eighth, twelfth and thirteenth centuries A.D. The northern boundary of citrus andBoehmeria nivea cultivation in the thirteenth century lay to the north of the modern distribution. During the last 1000 years, the thirteenth-century boundary was the northernmost. This indicates that this was the warmest time in that period. On the basis of knowledge of the climatic conditions required for planting these species, it can be estimated that the annual mean temperature in south Henan Province in the thirteenth century was 0.9 –1.0° C higher than at present. A new set of data for the latest snowfall date in Hangzhou from A.D. 1131 to 1264 indicates that this cannot be considered a cold period, as previously believed.

Recent dendroclimatic compilations from Northern Hemisphere temperature-sensitive tree-ring sites support a Medieval Warm Period (MWP) spanning parts of the 8th through 12th centuries AD. A newly-compiled, well-replicated ring-width chronology from Columbia Bay is a record of temperature variation along the maritime southern Alaskan coast and now spans the MWP (AD 774-2000). Over the past two decades the tidewater Columbia Glacier has experienced catastrophic retreat exposing almost 15 km of fjord. The ring-width record here is assembled from living trees and subfossil wood killed by a steady, millennium long glacial advance of the iceberg calving Columbia Glacier margin.

Preliminary dendroclimatic results using Regional Curve Standardization (RCS) techniques to extract a low-frequency climate signal suggest that the multiple decades centered on AD 1050 were warmer relative to the following centuries spanning the Little Ice Age. This warming is consistent with the reconstructed glacial record for the region that shows retracted ice margins during this time.

Evidence for Climate Variations Induced by the Solar Cycle

Abstract
We argue that the solar activity cycle induce periodic variations in rain-snow precipitation and sea-air temperatures, that cause mean sea level oscillations. We present observational evidence in favor of the above hypothesis, starting with a brief historical background of studies of solar cycle influence on climate. The evidence indicate that the Solar and Cosmic rays cycles are correlated with changes in temperature and precipitation. We analyzed data for the monthly mean sea level at San Juan and Magueyes Island in Puerto Rico, seeking correlations between sea level fluctuations and solar, cosmic rays and temperature cycles. Our analysis suggest that a solar activity cycle minimum (cosmic ray intensity maximum) correlates with lower than average temperatures and mean sea levels. We discussed, as a posible explanation of the above correlations, that the solar and cosmic rays cycles could cause larger than average accumulation of continental water and snow with lower temperatures contracting the oceans, thus implying lower mean sea levels. If this is the case, we predict that lower than average temperatures and mean sea levels will occur around the year 2009,with a delay of about 2 year after the 2007 solar activity minimum.
