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.


News of Climate Change

Scientists are already aware that air temperatures have been steadily rising since the 1800’s, resulting in the rapid melting of glaciers. The weighty glaciers covering Iceland have up until recently been pushing down on the land. Now that the ice is melting, pressure on the ground is being released, and the land is actually rising – at a rate of 1.4 inches per year.

Now geologists are concerned that these effects may result in increased volcanic activity or earthquakes in the country, which could be potentially disastrous, and not just to Iceland itself.  There are a number of active volcanoes in the country, such as the Eyjafjallajökull and the Bárbarbunga. The Eyjafjallajökull  is located in the southern part of Iceland, and it’s last eruption was in April 2010. Clouds of smoke were sent 20,000 feet into the air, and it brought European air travel to a complete halt for about a week. Bárbarbunga is currently in the midst of an eruption, emitting large volumes of sulphur dioxide and impacting the air quality in Iceland. Researchers at the University of Arizona and University of Iceland analyzed their findings from 62 global positioning system receivers placed throughout Iceland, which allowed the tracking of the land’s movement. They warned that as the glaciers continue to melt, the land will continue to lift. The prediction is that Iceland will rise 1.6 inches every year by 2025. As to whether this phenomenon is happening in other parts of the world, scientists aren’t too sure.  It is known that parts of North America are still slowly rising after the last major ice age which occurred thousands of years ago, but this is happening at a far slower pace than is happening in Iceland. The research, which has been published in the journal Geophysical Research Letters, will continue for at least several more years, as scientists monitor the situation.
