Tree-ring studies prove....

Why don't you refute the article, professor? Surely you're smarter than some cry baby Derp, Derp, screamin' for his puddin'!!

Oops, on second thought....
 
The warmers at this site are among the lamest the internets has to serve up. At least the alarmists elsewhere can cite some propaganda, despite it being easily shown to be faulty methods and confirmation bias.

What's the big deal about this study?

Is anyone arguing that this is the warmest time ever?

Idjits.

Yes, this is a peer reviewed paper in a highly respected journal.

An international team including scientists from Johannes Gutenberg University Mainz (JGU) has published a reconstruction of the climate in northern Europe over the last 2,000 years based on the information provided by tree-rings. Professor Dr. Jan Esper's group at the Institute of Geography at JGU used tree-ring density measurements from sub-fossil pine trees originating from Finnish Lapland to produce a reconstruction reaching back to 138 BC. In so doing, the researchers have been able for the first time to precisely demonstrate that the long-term trend over the past two millennia has been towards climatic cooling. "We found that previous estimates of historical temperatures during the Roman era and the Middle Ages were too low," says Esper. "Such findings are also significant with regard to climate policy, as they will influence the way today's climate changes are seen in context of historical warm periods." The new study has been published in the journal Nature Climate Change. Was the climate during Roman and Medieval times warmer than today? And why are these earlier warm periods important when assessing the global climate changes we are experiencing today? The discipline of paleoclimatology attempts to answer such questions. Scientists analyze indirect evidence of climate variability, such as ice cores and ocean sediments, and so reconstruct the climate of the past. The annual growth rings in trees are the most important witnesses over the past 1,000 to 2,000 years as they indicate how warm and cool past climate conditions were.
Researchers from Germany, Finland, Scotland, and Switzerland examined tree-ring density profiles in trees from Finnish Lapland. In this cold environment, trees often collapse into one of the numerous lakes, where they remain well preserved for thousands of years.
The international research team used these density measurements from sub-fossil pine trees in northern Scandinavia to create a sequence reaching back to 138 BC. The density measurements correlate closely with the summer temperatures in this area on the edge of the Nordic taiga. The researchers were thus able to create a temperature reconstruction of unprecedented quality. The reconstruction provides a high-resolution representation of temperature patterns in the Roman and Medieval Warm periods, but also shows the cold phases that occurred during the Migration Period and the later Little Ice Age.
In addition to the cold and warm phases, the new climate curve also exhibits a phenomenon that was not expected in this form. For the first time, researchers have now been able to use the data derived from tree-rings to precisely calculate a much longer-term cooling trend that has been playing out over the past 2,000 years. Their findings demonstrate that this trend involves a cooling of -0.3°C per millennium due to gradual changes to the position of the sun and an increase in the distance between the Earth and the sun.
"This figure we calculated may not seem particularly significant," says Esper. "However, it is also not negligible when compared to global warming, which up to now has been less than 1°C. Our results suggest that the large-scale climate reconstruction shown by the Intergovernmental Panel on Climate Change (IPCC) likely underestimate this long-term cooling trend over the past few millennia."

I tell you what. Why don't you study the environmental field at a professional level for 5 or 6 years and then I'll have a one sided conversation with you when you've advanced yourself to the "Rookie" level.

Oh no, not another global warming fear monger spouting shit...

love your use of science to dispute the information in the article. Very profound.

Anthropogenic Climate Change isn't exactly my area of expertise in the environmental field but if I should decide to research that route I'm probably going to reference profesionals who work in the field and then I'll base my conclusions on the available data and not what the Petroleum Institute of America tells me I should conclude. Just as if I decide that I have an impacted wisdom tooth I shall consult a Dentist and not some neophytes on a message board.
 
Prove is such a strong word. I prefer "provide evidence for ..." especially when talking about science.

I have a better idea. Why don't you refute the article?

LMAO... so you yet again refuse to look at the peer reviewed paper because it might blow yet another hole in your global warming fear mongering religion?

ROFLMAO... right, it most certainly is not your area of expertise. For you to claim that you are a scientist is pathetic. For you consistently ignore anything that might refute your religious AGW belief and resort to pathetic 'oh dat was paid fur by big oil' in an attempt to dodge a peer reviewed paper.

Some scientist you are.

LOL. Can you imagine? Oh Tom I have an impacted wisdom tooth what should I do? And then top will come along and say, wtf are you asking a Brit for they pull their bad teeth out with a pliers!

Can you imagine Tom pointing out an article written by a Dentist and peer reviewed? Think you two twits can imagine that? It is not Tom that is stating it. That is the point you two half wits cannot comprehend.

I didn't read any of it I just found the dentist thing really funny. It doesn't take you long to get your first wedgie of the day does it. No one ever said "rise and shine!" to you I bet.
