And you know this how?
Did you get it from bogus science reports?
Are you a time traveler?
By the way in case you missed it, apparently while all this fuss over global warming has been going over the last 10 years global warming has stopped?
Climatologists Baffled by Global Warming Time-Out
Of course they would be baffled if they were convinced that man made global warming was real, because if they did believe that then the warming could only continue right? So we should be boiling by now!
Too bad they couldn't eliminate the data that supports the following...
Global warming appears to have stalled. Climatologists are puzzled as to why average global temperatures have stopped rising over the last 10 years. Some attribute the trend to a lack of sunspots, while others explain it through ocean currents.
At least the weather in Copenhagen is likely to be cooperating. The Danish Meteorological Institute predicts that temperatures in December, when the city will host the United Nations Climate Change Conference, will be one degree above the long-term average.
Otherwise, however, not much is happening with global warming at the moment. The Earth's average temperatures have stopped climbing since the beginning of the millennium, and it even looks as though global warming could come to a standstill this year.
Ironically, climate change appears to have stalled in the run-up to the upcoming world summit in the Danish capital, where thousands of politicians, bureaucrats, scientists, business leaders and environmental activists plan to negotiate a reduction in greenhouse gas emissions. Billions of euros are at stake in the negotiations.

Is this science 100% accurate? No. Most sciences change and adapt to the new evidence that collects over time. Its the only method humans have to find out the real truth. Personally I'd rather err on the side of climate change happening and that perhaps we can delay or offset the consequences. To do nothing and keep forging ahead, thinking our actions have no effect on the planet is a fools game.

Right. Those are the years before satellites. I argue that data from back then was to iffy to be relevant anyways, so if it did hurt their mythology that makes it even more embarassing.
Not really IIB, the data that they threw away is most of the 150 years of raw temperature data until the 1980s when the records were thrown away.
In the 1980s we had satellites, not as many as now, but we had satellites taking temperature readings. in fact it was around 1979 that we began taking satellite temperature readings, but before that we were taking radiosonde temperature readings by way of weather ballons since about 1924, but have also HAD other records going back to 1850....
ALL that data was thrown away.....which is MOST of the raw data for the past 150 years.... We now have only the data since the 1990s until today.......
But we know for a fact that during the 1930s there have been record temperatures that are among the WARMEST....
We know that AT LEAST 4 of the warmest years were in the 1930s...and there were also WARMEST years in the 1920s, and even before.
NASA Revises Temperature Data - 1930's warmest on record!
Admin, Thursday 09 August 2007 - 20:06:13 // comment: 1 // // Font Size - Increase / Decrease / Reset
In a stunning turn of events data (quietly) released by NASA shows that the 4 warmest years ever recorded occurred in the 1930's, with the warmest year on record being 1934 (not 1998). Lets see if Al Gore revises his road show. Update - Global Warming is actually a Y2K bug!
Data discovered on NASA's Goddard Institute for Space Studies (GISS) website revises recorded temperatures for the United States. It is expected that similar revisions will also be made for global temperature recordings. This information was discovered by Steve McIntyre of Climate Audit on Wednesday (8/8/2007). No NASA press release, no James Hansen (head of GISS) announcement, nothing. Could it be because they don't want anyone to see it? The data is certainly devastating for the Al Gore camp which has based much of their Carbon Credits sales pitch on recent temperatures (e.g. claiming that 1998 was the warmest on record).
Other aspects of the data are just as stunning.
Only 4 of the top 10 warmest years occurred in the past 10 years (1998, 1999, 2006)
Out of the top 10 warmest years half occurred before 1940
The years 2000, 2002, 2003 and 2004 were cooler than the year 1900
1996, just two years before what Al Gore called the hottest year in the history of the planet, was actually cooler than average.
1921 was the third warmest year in recorded history (behind 1934 and 1998).

Seriously, use your head here. You're talking about global data. Do you think that Japan, for example, would send the original meterological history archive, going back centuries, to a foreign university, in its entirety, no questions asked, and without keeping a copy on hand?

Surprise In Earth's Upper Atmosphere: Mode Of Energy Transfer From The Solar Wind
"Its like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down," said Larry Lyons, UCLA professor of atmospheric and oceanic sciences and a co-author of the research, which is in press in two companion papers in the Journal of Geophysical Research.
Space radiation hits record high
Now, the influx of galactic cosmic rays into our solar system has reached a record high. Measurements by NASA's Advanced Composition Explorer (ACE) spacecraft indicate that cosmic rays are 19 per cent more abundant than any previous level seen since space flight began a half century ago."The space era has so far experienced a time of relatively low cosmic ray activity," says Richard Mewaldt of Caltech, who is a member of the ACE team. "We may now be returning to levels typical of past centuries."

Observational arguments in favor of such a cloud are presented, and implications of the presence of a nearby cloud are discussed, including possible changes in terrestrial climate. It is suggested that the postulated interstellar cloud should encounter the solar system at some unspecified time in the near future and might have a drastic influence on terrestrial climate in the next 10,000 years.

This past decade has been the warmest GLOBALLY on record.
This is what the science shows.
Temperatures in Antarctica during warm periods between ice ages soared to up to 6C warmer than the present day, a study has shown.
Until now temperatures during the warm periods between ice ages - known as interglacials - were thought to be only slightly warmer than those of the present day, British Antarctic Survey (BAS) scientists explained. But the findings, published this week in journal Nature, show brief spikes in temperature, which recur roughly every 100,000 years and last a few thousand years, seem to have been a lot warmer.

Subfossil remains of wood and peat from six Swiss glaciers found in proglacial fluvial sediments indicate that glaciers were smaller than the 1985 reference level and climatic conditions allowed vegetation growth in now glaciated basins. An extended data set of Swiss glacier recessions consisting of 143 radiocarbon dates is presented to improve the chronology of glacier fluctuations. A comparison with other archives and dated glacier advances suggests 12 major recession periods occurring at 9850- 9600, 9300-8650, 8550-8050, 7700-7550, 7450-6550, 6150-5950, 5700-5500, 5200-4400, 4300-3400, 2800-2700, 2150-1850, 1400-1200 cal. yr BP. It is proposed that major glacier fluctuations occurred on a multicentennial scale with a changing pattern during the course of the Holocene. After the Younger Dryas, glaciers receded to a smaller extent and prolonged recessions occurred repeatedly, culminating around 7 cal. kyr BP. After a transition around 6 cal. kyr BP weak fluctuations around the present level dominated. After 3.6 cal. kyr BP less frequent recessions interrupted the trend to advanced glaciers peaking with the prominent ‘Little Ice Age’. This trend is in line with a continuous decrease of summer insolation during the Holocene.

Title: Torneträsk tree-ring width and density ad 500–2004: a test of climatic sensitivity and a new 1500-year reconstruction of north Fennoscandian summers
In: Climate Dynamics

Abstract: This paper presents updated tree-ring width (TRW) and maximum density (MXD) from Torneträsk in northern Sweden, now covering the period ad 500–2004. By including data from relatively young trees for the most recent period, a previously noted decline in recent MXD is eliminated. Non-climatological growth trends in the data are removed using Regional Curve Standardization (RCS), thus producing TRW and MXD chronologies with preserved low-frequency variability. The chronologies are calibrated using local and regional instrumental climate records. A bootstrapped response function analysis using regional climate data shows that tree growth is forced by April–August temperatures and that the regression weights for MXD are much stronger than for TRW. The robustness of the reconstruction equation is verified by independent temperature data and shows that 63–64% of the instrumental inter-annual variation is captured by the tree-ring data. This is a significant improvement compared to previously published reconstructions based on tree-ring data from Torneträsk. A divergence phenomenon around ad 1800, expressed as an increase in TRW that is not paralleled by temperature and MXD, is most likely an effect of major changes in the density of the pine population at this northern tree-line site. The bias introduced by this TRW phenomenon is assessed by producing a summer temperature reconstruction based on MXD exclusively. The new data show generally higher temperature estimates than previous reconstructions based on Torneträsk tree-ring data. The late-twentieth century, however, is not exceptionally warm in the new record: On decadal-to-centennial timescales, periods around ad 750, 1000, 1400, and 1750 were equally warm, or warmer. The 200-year long warm period centered on ad 1000 was significantly warmer than the late-twentieth century (p < 0.05) and is supported by other local and regional paleoclimate data. The new tree-ring evidence from Torneträsk suggests that this “Medieval Warm Period” in northern Fennoscandia was much warmer than previously recognized.

Nile gauge records of variations in Nile floods from the 9th century to the 15th century AD reveal pronounced episodes of low Nile and high Nile flood discharge. Historical data reveal that this period was also characterized by the worst known famines on record. Exploratory comparisons of variations in Nile flood discharge with high-resolution data on sea surface temperature of the North Atlantic climate from three case studies suggest that rainfall at the source of the Nile was influenced by the North Atlantic Oscillation. However, there are apparently flip-flop reversals from periods when variations in Nile flood discharge are positively related to North Atlantic warming to periods where the opposite takes place. The key transitions occur atAD 900, 1010, 1070, 1180, 1350 and 1400. The putative flip-flop junctures, which require further confirmation, appear to be quite rapid and some seem to have had dramatic effects on Nile flood discharge, especially if they recurred at short intervals, characteristic of the period from the 9th to the 14th century, coincident with the so-called Medieval Warm Period. The transition from one state to the other was characterized by incidents of low, high or a succession of both low and high extreme floods. The cluster of extreme floods was detrimental causing famines and economic disasters that are unmatched over the last 2000 years.

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 1°C 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.

Evidence for the existence of the medieval warm period in China
(1) Chinese Academy of Meteorological Sciences, Baishiqiaolu No. 46, 100081 Beijing, China
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.
