Arctic Sea Ice Loss Strongly Linked to Rise in Greenhouse Gasses
03.05.2012
A new study conducted by scientists from the Max Plank Institute for Meteorology in Germany shows a strong, physically plausible correlation between rising concentrations of greenhouse gases in the atmosphere and diminishing sea ice in the Arctic.

Study Shows Increase in Atmospheric CO2 Helped End Last Ice Age
10.04.2012
Scientists have been able to reconstruct past temperatures using proxy methods such as reading ice cores, tree rings and sediment cores from the bottom of lakes and oceans. They have also been able to reconstruct past levels of the greenhouse gas carbon dioxide (CO2) in the atmosphere from air bubbles…

Thawing Permafrost Attributed to Acute Global Warming in Past
10.04.2012
An international study conducted by researchers from the US, Italy and the UK published in Nature has shown that past thawing of permafrost on Earth and the carbon that was released from it into the atmosphere led to a runaway warming effect.

NRC Releases Synthesis of Reports on the State of the Polar Regions
04.04.2012
The US National Research Council (NRC) has just released a synthesis of reports from thousands of scientists from 60 countries who participated in research projects during the International Polar Year (IPY) 2007- 2008.

Increasing Levels of Greenhouse Gasses Disrupting Glaciation Patterns
09.01.2012
According to a study conducted by researchers from University College London, the Unviersity of Cambridge and the University of Florida and published in Nature Geoscience, unprecented levels of greenhouse gasses in the atmosphere are disrupting the Earth’s normal patterns of glaciation and may delay the onset of the next ice…

CryoSat-2 Monitoring Oceans Now, Too
26.12.2011
According to the European Space Agency, its CryoSat-2 satellite will soon be used to monitor sea conditions for marine forecasting. The satellite was launched in April 2010 to measure variations in land and sea ice thickness in the Polar Regions, and the satellite has delivered. However while the satellite’s orbit…

Lessons from the Arctic for Drilling Ice Cores in the Antarctic
17.10.2011
Glaciologists from the Australian Antarctic Division (AAD) have recently returned from visiting the North Greeland Eemian Ice Drilling (NEEM) project, which is extracting ice cores from the Greenland Ice Sheet, to learn a few things that might help them with drilling they plan to undertake on the Antarctic Ice Sheet…

Pole-to-pole Flights Provide First Global Picture of Greenhouse Gases
12.09.2011
After three years of research, a far-reaching project known as HIPPO allowed researchers to generate the first detailed 3D mapping of the global distribution of gases and particles that affect Earth’s climate. Using a specially designed aircraft to fly to different parts of the globe, the scientists were able to…

Using Ethane to Track Atmospheric Methane Levels
19.08.2011
Research conducted in Greenland and Antarctica and published in the journal Nature suggests a common cause between between the decline of atmospheric methane (CH4) and atmospheric ethane (C2H6)at the end of the 20th century. Scientists involved in the study believe the drop in fossil-fuel sources is likely related to changes…
