Global warming is happening. Temperatures have already risen by 0.76 degrees since the industrial revolution and are projected to rise further by 1.8 - 4 degrees by the end of the century. The last time climate change happened at this pace was 125,000 years ago and led to a 4-6 metre sea level rise.
Global warming at the upper end of the scale predicted by the Intergovernmental Panel on Climate Change would have catastrophic consequences for Europe. Up to 30% of plant, animal and bird species would be wiped out and the threat of natural disasters such as landslides, floods and mudslides would increase significantly.
