There seems to be a roughly linear increase of the temperature from about 1800, or even much earlier, to the present. This warming trend is likely to be a natural change; a rapid increase of CO2 began in about 1940. This trend should be subtracted from the temperature data during the last 100 years. Thus, there is a possibility that only a fraction of the present warming trend may be attributed to the greenhouse effect resulting from human activities.

I dunno wether its true or not about the environment but I stopped driving my car a little over 2 years ago now when gas prices started rising. Does it really hurt people that much to be a little concerned and to conserve when possible? Im wondering if this Dr. Akasofu being that he is in Alaska and being that his research deals in electromagnetics and auroras if he has anything to do at all with HAARP.
At the International Arctic Research Center, which was established under the auspices of the “US-Japan Common Agenda” in 1999, our researchers are working on the arctic climate change issues mentioned in the above, in particular, in distinguishing natural changes and the manmade greenhouse effects in the Arctic. The term “most” is very inaccurate.

We recovered form the last Ice Age many thousands of years ago, and if anything have been in a slow decline for the past 4 thousand years or so - as can be seen in the data from the Greenland ice cores (Alley 2000):-
The Arctic shelf is currently undergoing dramatic thermal changes caused by the continued warming associated with Holocene sea level rise. During this transgression, comparatively warm waters have flooded over cold permafrost areas of the Arctic Shelf. A thermal pulse of more than 10°C is still propagating down into the submerged sediment and may be decomposing gas hydrate as well as permafrost.

Sorry to tell you that even thou in that article they do say Little Ice Age, there have been other research which does demonstrates we are still having the effects of Holocene warming since we came out of the Ice Age. The Holocene is the period after the Ice Age.

astrocreep, you are right. This issue has become politicized to the point that any scientist who doubts that mankind has caused the 20th century warming is immediately labeled as an "oil stooge", a "government agent" or some such nonsense.
