Those changes may include the loss of Arctic summer sea
ice, the
collapse of
ice sheets in Greenland and
western Antarctica, dieback of the Amazon rainforest and changes in the jet stream and the pattern of El Niño and La Niña weather cycles.
The prime contenders are the melting of the West Antarctic

sheet, the melting of the Greenland
ice -
sheet (whose
collapse some scientists believe will now be hard to prevent), and the thawing of peat bogs in
western
Results of a recent long - term and large - scale simulation of the
collapse of the

Ice Sheet (WAIS) show that the destabilization of the entire ice sheet would be irreversible if current conditions don't change by 20
