Antarctica: a Testing Ground for Life Adaptation Amidst Climate Change

Janina Lazo-Cruz — Tue, 06 Mar 2018 20:18:05 +0000

Imagine this: an island in Antarctica so white for it was mostly covered with thick sheets of ice that no earthen colors are visible to the naked eye. Ten years after, this landscape has changed into something unfamiliar: people can now see “rocks that we weren’t seeing five or 10 years ago, and that is […]

Is Antarctica Melting? Yes, but It (Probably) Won’t Disappear

Is Antarctica melting? Yes, and in fact, it is melting at a higher rate than other masses of ice around the world. Antarctica has been around for fifteen million years, but if humans do not stop burning fossil fuels, the continent could disappear for good. If all the fossil fuels stored within the Earth are burned, […]

Satellite Mission Reveals Antarctica’s Ice Melts Cause Change in Earth’s Gravity

Satellite imagery can now help scientists determine the amount of ice lost from Antarctica by presenting exact measurements of the gravity of the Earth. European Space Agency’s latest the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission revealed that melting of ice sheets has caused deviation in the planet’s gravitational norm. It has been long […]

Giant Glaciers Melting Past the Point of No Return

You’ve probably heard the recent news that the ice sheets covering Greenland and Antarctica are melting at an even faster rate than previously suspected. To get an idea of the gravity of the situation you need to understand this: in some places, the ice sheets that cover Antarctica and Greenland are more than two miles […]

Antarctica’s Ice Cover Thickens Due to Climate Change, Affects Sea Level Rise

Mila Luleva — Mon, 01 Apr 2013 18:23:44 +0000

Scientists explain why sea ice around Antarctica is becoming thicker despite the rise in global temperatures in a new study published in the latest issue of Nature Geoscience. During the summer months, ice sheets melt and cause upwelling of fresh water. This water floats on top of the warmer salty water in the form of a […]

Antarctica More Responsible for Rising Sea Levels Than Greenland

Leigh Hutchens — Sat, 26 Jan 2013 08:35:24 +0000

Over 300 experts from 14 different countries have collectively determined that Greenland’s ice is much less vulnerable to a runaway melt than previously determined. In fact, the experts predict that Antarctica might actually be more responsible for the rising sea level than Greenland. The study was born from a desire to understand melting ice stores […]

Synchronous Rise in Temperature and Carbon Dioxide Associated with Climate Change

Maria Reyes — Wed, 25 Jul 2012 06:40:36 +0000

The greatest climate change in the last 100,000 years was the shift from ice age to the warm interglacial period 19,000 years ago. New research showed temperature rise was closely followed by a rise in carbon dioxide during this shift. Scientists previously thought there was a gap of about 1000 years; new evidence suggested the […]
