Efter sensationelle 2 hvide Jul i streg er det måske på sin plads at mindes, hvor ekstrem sjælden et sådan fænomen egentligt er, især i en tid med global opvarming. Her refererer United Nations Enviroment Programme fra FNs Klimapanels 2007 rapport

A full-length chapter in the newly released report from the Intergovernmental Panel on Climate Change (IPCC) describes the ongoing thawing of European glaciers and permafrost, the delayed winter freeze of rivers and lakes, the lengthening of growing seasons, the earlier spring arrival of migratory birds, and the increasing frequency of weather extremes such as the disastrous heat wave of 2003.

?Having just experienced the warmest winter on record, Europeans can clearly see that their climate is changing, and changing rapidly?, said Achim Steiner, Executive Director of the United Nations Environment Programme, which, together with the World Meteorological Organization, established the IPCC in 1988.

?Many of the additional changes anticipated over the coming decades are disturbing, while those that may at first glance seem attractive to some people ? such as warmer northern winters ? will come with many local drawbacks and at a high price for the world as a whole.?

?These expected impacts confirm the wisdom of the European Union?s newly agreed target of reducing greenhouse gas emissions by 20% by 2020. They should also inspire movement towards even greater reductions as well as early action to adapt to Europe?s emerging new climate conditions,? he said.

De hårde vintre er grunden til at man nu taler om klimaforstyrrelser, frem for global opvarmning. Vejr og klima er ikke det samme, med mindre vejret altså er virkeligt dårligt for så er det klima-forstyrrelse.
