This doubling can be equated with the burning of all the still existing fossil fuels ? there- fore is the value of 1°C uncritical and gives no reason for disaster warnings.? The spectacular announcement of theIPCC of 3 to 5 °C and more are obtainedby positive feedback mechanism in the computer scenarios. These are highly contentious and by nothing proved. ?Under consideration of all these facts we should therefore concentrate with all ourmeasures more on environmental protec- tion, than develop multi-billion dollar methods to avoid CO2.? In additon to this says the director ofthe Meteorological Institute of the Uni-versity Berlin: ?It?s about time to place the environmental protection into the worldwide focus of any action. Clean air, clean water, an intact ecosystem are the benefit for all human beings today and in the future. How ideologically presump- tuous must someone be to specify a ?2-degree target? for the nature?? In this regard it is very interesting to note that the Arctic melting since 2007 has not increased, but instead, in the years 2008 ? 2010, more ice could be re-alized. Here it is quite amazing, in fact, when in earlier years a few experts al- ways theorize about an irreversible ?tip- ping point? of the Arctic melt. Recently there are indications that such specula-tions about all kinds of man-made cli-mate tipping points come to where they belong to: into the waste basket of the science.For example, a VLCC(Very Large Crude Car- rier) with deadweight ton-nage of more than 200,000, which currently consumes 23,000 tonsof heavy fuel oil, will onlyrequire 14,000 tons in 2030 if built in accordance with the EEDI requirements. For 2020, the experts expect annual fuelcost savings of about$50 billion, and in2030 savings should be$200 billion.MR#9 (34-41):MR Template 9/11/2012 4:23 PM Page 37
