The ongoing rise in greenhouse gas emissions may trigger a rapid, irreversible collapse in an Antarctic ice sheet the size of Mexico, with potentially catastrophic consequences, a study published last week in the journal Nature found.
Extreme temperatures linked to climate change can be expected to cause a significant increase in the number of premature deaths, according to a report released Monday by the Obama administration.
A new report nearly doubles previous predictions for sea level rise if global emissions continue unabated, portending a doomsday scenario for many of the world’s coastal cities.

According to a researcher, Frank Pokiak, snow in Arctic has been melting faster than earlier estimates. In November 2014, sea ice of Arctic had covered about 630,000 square kilometers much less oceans than what it covered about 30 years ago. Sea ice in the area has been shrinking about 5% every 10 years. Stressful thing about the condition is that the frozen ice is present not only in smaller size, but its thinner too.

David Barber, who holds the Canada Analysis Chair in Arctic Technique Science at the University of Manitoba, said that sea ice has lost approximately 40% of its total size. Barber said, "We found this rotten ice in the summer time of 2009. It was multi-year sea ice that had deteriorated so substantially that the melt ponds had gone by means of and connected with the oceans". Barber further said that the ice had broken is several tiny pieces and the pieces were congealed with new ice that was forming at that time. When a ship was driven via it, the rotted ice didn't slow the ship down, Barber added. According to Barber, it is very difficult to predict anything about what will happen with this ice in future. CJ Mundy, University of Manitoba biologist, said that all Arctic life starts with algae that have started blooming under the ice every March. Organisms and plants of the regions take advantage of resources when they grow to be accessible. According to Mundy, the organisms of the region could face a problem where they will survive the rest of the season without obtaining access to additional meals. Melting of sea ice could lower the length of the ice algae bloom.
