75% of common European birds at risk from climate change

Climate change is already having a detectable impact on birds across Europe. This is the message from a group of scientists who have created the world’s first indicator of the impacts of climate change on wildlife at a continental scale. “We hear a lot about climate change, but our paper shows that its effects are being felt right now”, said lead author Dr Richard Gregory from the RSPB (BirdLife in the UK).

Of the 122 common species included in the analysis, 75% are predicted to experience declines across their ranges if they continue to respond to climatic warming in the way the models predict, and in the absence of other barriers. The remaining 25% are projected to increase.

“The results show the number of species being badly affected outnumbers the species that might benefit by three to one”, commented Dr Gregory. “Although we have only had a very small actual rise in global average temperature, it is staggering to realise how much change we are noticing in wildlife populations. If we don’t take our foot off the gas now, our indicator shows there will be many much worse effects to come. We must keep global temperature rise below the two degree ceiling; anything above this will create global havoc”.

Published in the journal PloS ONE, scientists showed a strong link between the observed population change of common and widespread European bird species and the projected range change associated with climate change. By pulling all the data together, the team compiled an indicator showing how climate change is affecting wildlife across Europe. The new indicator has already been included in a high profile set of indicators being used by the European Commission to assess progress towards the target of halting biodiversity loss by 2010.

The paper and the indicator were produced by a team of scientists from the RSPB (BirdLife in the UK), Durham University, the University of Cambridge, the European Bird Census Council, the Muséum National d’Histoire Naturelle, the Czech Society for Ornithology (BirdLife in the Czech Republic), and Statistics Netherlands.

The Climate Change Indicator combines two independent strands of work: bioclimate envelope modelling, and observed population trends in European birds, derived from the Pan-European Common Bird Monitoring Scheme. When a bird’s population changes in line with the projection, the indicator goes up. Species whose observed trend doesn’t fit the projection cause the indicator to go down.

  1. What are the sources of information kept by the Dr Gregory? Why (he does not say it) if the temperature takes up birds from 2 degrees can die?

  2. God help us. When will our insanity end? I can’t help but despair as I hear enthusiastic cries of “get rich investing in clean energy” and “how you can benefit from climate change”…

    If humanity were one individual, we would be locked up in an insane asylum.
