This is what the original article "sez" (you know the scientists, the "real ones"):On 2006-06-24 10:59, garyb wrote:
here's an article whose headline sez it all. this is the warmest it's been since 1600. they can't really even speak with any certainty before that, really not even before about 1850! (no reliable measurements....) that is a VERY small sampling of the many thousands of years of human existance and millions of years of earth's existance. it is too small to be sure of anything. scientists(real ones...) THINK it makes sense that hhuman activity is responsible for at least SOME of the temperature rise, MAYBE even all of it for SOME of this period, but what is NOT clear, is what effect if any, our actions will have in any long time period(even 50 years). the system is to a large part, self regulating. the sun and other natural components potentially are much bigger factors...
WASHINGTON -- There is sufficient evidence from tree rings, boreholes, retreating glaciers, and other "proxies" of past surface temperatures to say with a high level of confidence that the last few decades of the 20th century were warmer than any comparable period in the last 400 years, according to a new report from the National Research Council. Less confidence can be placed in proxy-based reconstructions of surface temperatures for A.D. 900 to 1600, said the committee that wrote the report, although the available proxy evidence does indicate that many locations were warmer during the past 25 years than during any other 25-year period since 900. Very little confidence can be placed in statements about average global surface temperatures prior to A.D. 900 because the proxy data for that time frame are sparse, the committee added.
Are you freaking joking? If the past 150 years of data indicate that human activities led to the rise of the surface temperatures, how in gods name is it NOT clear what will happen in the next 50?On 2006-06-24 10:59, garyb wrote:
