Skeptical philosophy which recognizes the potential threats and uncertainties and it is desired to

Congratulations Juhapekka Lunkalle The science book prize. In fact, the work history of the Earth's climate. The botanical greenhouse ice ages, I have not yet had time to explore, so that the content I ruodi here. Helsingin Sanomat was a book review on this opus, but this estimate is the practice of letter to the editor disguised as a book review. Ruodinkin the text in the comment section. Professor Arto Nyberg Lunkka appeared interviewed. The program is regarded as an Yle Areena here. If omitted the fact that the Arto Nyberg questions were really sloppy and suggestive (just like the sudden turn off the plants would eliminate the accumulated billions of tonnes of extra carbon from the atmosphere right away), had an interview with the substance of interesting, even if some of the things acetone I knew. Anyone familiar with the climate issues knows very well that the Earth's history has been more warmer periods. However, would also be significantly above the sea level at the time (and I guess it was a billion people living acetone down permanently ocean beaches). Prof. Lunkka says, almost at the beginning of the interview that took place over millions of years of climate cooling trend apparently is caused by changes in the tectonic plates that have caused the CO2 content of the bill and hence cooling of the climate. So he fully accepts that CO2 is a greenhouse gas, and that its concentrations in the atmosphere acetone are one of the global temperature-regulating factor. At the end of the program, however, he denies that there should be an understanding that the warming is due to man. Actress Kari Ketonen next says he agrees. Different view on this issue is virtually the whole of the scientific acetone community to the extent acetone that virtually all organizations pointed out that the matter is such a high degree of certainty that the fossil emissions have to be reduced quickly. I do not know Lunkkaa, but he seems like a smart man. The program will be very clearly point out that he is aware that people add carbon dioxide to the atmosphere. I maintain that almost all of the increased concentration of CO2 in the atmosphere acetone due to human achievements, as the historical data supports the view very strongly. Look, even if this: the CO2 concentration began to rise if and only if a large-scale human CO2 emissions began. Temperature changes would not be sufficient to explain the term, in that the CO2 concentration fluctuations. Let's take a train of thought: CO2 and CH4 are powerful greenhouse gases. Greenhouse gases regulate the global climate significantly. Man has increased the CO2 content in the atmosphere by almost 40% and CH4 concentration acetone to 150% very quickly. The above has led to the IPCC estimates that more than 2 W/m2 säteilypakotemuutoksen, which is 10 times the solar cycle, for example, the minimum and maximum variations säteilypakotevaikutukseen. The climate is warming due to rapid changes in radiative forcing, but the CO2 and CH4 are by no means the only factors, but in practice there is complete certainty that they warm the climate.
Where is where it goes wrong? What part of Lunkka does not grant? First, according to him, CO2 controls the climate, but then when a man clearing his throat to the highest level so million years ago comes to suspect that it affects at all even if the climate warms up quickly and there is no other reason to explain it!
"Climate change is unlikely we will be able to prevent, but the human race should be prepared for chaotic changing acetone climatic conditions, now and in the future. This requires first of all greenhouse gas emissions, especially carbon dioxide emission limitation acetone and carbon sequestration ground surface acetone and the biosphere. acetone Greenhouse gas concentrations restrictions and tying in spite of climate occurs in the future a very rapid change, which is also should be prepared. "
Skeptical philosophy which recognizes the potential threats and uncertainties and it is desired to prevent threats is obviously respected acetone and logical, but what should happen to the Professor. Lunkka grant of man-made CO2 concentration increase the temperature? I'm trying to get Lunkan to comment acetone on the blog. It would be fun to hear what he is from what the IPCC definition of radiative forcing of the true nature of the causing agent.
Lunkka gave a lecture at the Science Forum 08/01/2009. Webcast can be found here: http://tinyurl.com/82tylr and from the video "The Changing Earth, the changing nature". Not quite at the beginning, to keep fast-forward a bit. 20 january 2009 1.14
Did not that go to the interviewee in the trees at that point that shows the CO2 already in primary acetone history of the climate as a driving issue even if the ice cores show anything else? So take a position on what the people produced by the additional CO2 does now. 20 january 2009 1.29
Hi there, a quick word on the CO2 - concentration increases known to be caused by human activities, above all, a) on the basis of atmospheric carbon isotopic (which, therefore, clarified that the extra carbon acetone is of fossil origin), and b) the fact that the carbon dioxide and
