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.

Researchers project that carbon emissions will continue on a business-as-usual scale and complications from the melting of the ice sheet in the West Antarctic, will add further to that reality.

A new report is arguing that due to carbon emissions, there is nothing that can be done to save the cities of Miami and New Orleans – but with a lot of effort by world leaders, perhaps something can be done to save countless other cities and towns. However a coastal metropolis like Boston isn’t within the prime ten. It should be noted that this would be the case of extreme circumstances, but nonetheless possible. “Philadelphia has a very large drawback underneath the worst-case situation, however, a really small drawback beneath the flawless case state of affairs”. If we somehow manage to slash global carbon emissions by 2050, the impact could be much less, though we’ll still lose Coney Island. Other Pennsylvania population centers that could reduce the impact of widespread flooding, allowing thousands of people to stay in their homes, include the riverside communities of Bristol, Croydon and Chester, the report said. In Bristol, eight, 382 of the city’s 9,726 folks stay in areas that will be beneath the excessive-tide line if emissions stay unchecked, contrasting with exclusively 242 individuals who can be flooded out underneath an excessive discount of emissions. And in New Castle, land that was home to about 3,000 people would be spared flooding if emissions were cut to the lowest level, the study found. The carbon eventualities, known as Consultant Focus Pathways (RCP), are given numerical values that characterize insurance policies starting from “excessive” cuts to “unchecked air pollution”. The long-time period SLR projection is about seven occasions the consensus estimate for the worldwide improve by 2100. For example, for Florida, which is the most threatened state due to sea level rise, aggressive global carbon emissions cuts could prevent the submergence of land that is now home to about 5.6 million people, as compared to unabated emissions.

Such radical cuts may encompass a speedy swap to renewable fuels and/or elevated use of nuclear energy, Strauss stated. “Some of this could happen as early as next century”, Strauss told AFP. According to earth scientist Michael Mann, a well-known author on climate change, the latest findings are a “useful contribution to the literature”. But Mann argued that the new study might actually understate the additional flooding risk from higher sea-level rise because it does not explicitly anticipate bigger hurricanes resulting from climate change. “The answer could be sooner than 200 years from now, or as long as 2,000 years”, explains the mapping site. Researchers also dwelt on a situation where carbon emissions could peak by 2020. The two seem to have now been placed on an irreversible path. But it does not take into account the fact that, say, New Orleans is now protected by a 26-foot-high sea wall, and that the state of Louisiana is contemplating diversions of the Mississippi River that would create new wetlands that might keep pace, at least to a few extent, with rising seas. It lets you choose any USA city or zip code to see what rising seas will do to your nominated address, based on a range of projections about how high sea levels could increase. The analysis turns on a critical number: For every 1 degree Celsius of warming, the scientists estimate that we should expect 2.3 meters of long term, eventual sea level rise, playing out over millennia. “Under all scenarios, Florida has the plurality or majority of committed cities with total population greater than 100,000”, the study reports.
