Problem

The evidence for rapid climate change is compelling:

  • Global temperature rise
  • Warming oceans
  • Shrinking ice sheets
  • Glacial retreat
  • Decreased snow cover
  • Sea level rise
  • Declining Arctic sea ice
  • Extreme events
  • Ocean acidification

Scientific evidence for warming of the climate system is unequivocal.
