Det går åt pipsvängen fortare än vi anat
Kommissionen för hållbar utveckling har låtit sammanställa den senaste kunskapen om klimatfrågorna och med viss vinkling på Sverige. Såtillvida får vi veta att vintern 2007-08 var den varmaste i mannaminne i östra Sverige även om just en sådan observation inte i sig indikerar klimatförändringen.
Det gör däremot avsmältningen av is i Arktis (se bild) och det så markant att man kan ana att man nu fått den tröskeleffekt efter vilken det bara bär snabbare och snabbare utför. Det finns också indikationer att kolsänkor (som motåtgärd) inte är så effektiva som man antagit. Det finns alltså anledning att vara skeptisk till trädplanteringar som botemedel. Vilket naturligtvis inte legitimerar eller gör skogsskövlingar mindre allvarliga!
