In addition to worrying consequences such as the possible shift of ice-free summers into a regular feature across most of the Arctic Ocean, Pierce enumerates a series of issues that will have affect directly European countries, in particular the UK but with scary feedback to the rest of the world.

One among many other risks due to warming trends that would affect the Arctic region is tsunami risk along with sea level rise and, consequently, flooding events. In the conference Planet Under Pressure, Euan Nisbet, a researcher of the University of London, warns us that warming ocean currents east of Greenland were melting ice in the seabed.

As a result, this would have serious impact on landscape patterns in the Northern Europe including Iceland and the UK. Fred Pearce writes:
This could trigger landslides on steep submarine slopes in the area, unleashing tsunamis capable of hitting the UK.
Other risk is the threat of Arctic erosion as Carol Stevenson wrote on New Scientist in 2009 along with air circulation issue as consequences of climate change.

Additionaly, due to warming threats, observers put us on guard of risk of methane leaks from melting permafrost. Fred Pearce continues reporting Euan Nisbet's words:
[This would] release buried methane that could amplify global warming. Something similar happened off Norway 8000 years ago in a similar geological setting.
Admittedly, round about 3000 BC, a first collapse concerned Northern Europe due to Climate change translated into soils that blew away changing the forest and the woodland nature of Britain and most parts of Northern Europe, as Theologian Martin Palmer said to The Ecologist.

In this context, in a geological era dominated by human species, it is urgent to reengineer solutions to do with warming threats as the first concerned would be the local habitats. But which solutions?
