Arctic Ocean could become ice-free by 2030. Why it matters?
Scientists warn that the Arctic Ocean could be ice-free in summer by the 2030s. The loss of sea ice would have global and dangerous consequences.
Jonathan Bamber is a professor in physical geography. He graduated from Bristol University with a degree in Physics in 1983 and went on to complete a Ph.D at the Scott Polar Research Institute, University of Cambridge, in glaciology and remote sensing.

Although there are some regional differences in the magnitude of Arctic amplification, the observed pace of Arctic warming is far higher than the models implied
Satellite images can measure changes in sea level down to a millilitre or land and ocean temperatures, so scientists can carry out a full 'health check'.
Professor Jonathan Bamber, from the Bristol University, explains new research into Greenland's ice sheet - and why it should be cause for concern.
Multi-year ice helps reflect the sun's rays, reducing the rate of global warming. However, these ice sheets are rapidly disappearing, releasing CO2 and raising sea levels.
A study has found a range of future outcomes that go from bad to worse when it comes to the uncertainities around sea level rise.
