Renewed at a level of $32,475,000 over five years, ArcticNet, co-led by Professor Jackie Dawson of the Department of Geography, Environment and Geomatics, will be able to compete with the research efforts of any other nation studying the Arctic.

Listen to Professor Antoni Lewkowicz in an interview on Radio Canada's Les années lumières.

From Radio Canada: In Nature Communications, researchers report a very concrete effect of this increase: landslides related to thawing permafrost on Banks Island have increased 60-fold over the past 30 years, from 63 in 1984 to over 4000 in 2013. According to Antoni Lewkowicz, a professor in the Department of Geography, Environment and Geomatics at the University of Ottawa and one of the authors of this study, the link with rising temperatures is obvious, as 85% of this increase occurred after four particularly hot summers.

Increasing ground temperatures in the Arctic are indicators of global climate change, but until recently, areas of cold permafrost were thought to be relatively immune to severe impacts. A new study by Antoni Lewkowicz, a professor in the Department of Geography, Environment and Geomatics at the University of Ottawa and published in the journal Nature Communications, however, shows that areas of cold permafrost can be vulnerable to rising summer temperatures.

Gentrification is the process of rejuvenating deteriorated urban neighborhoods and it has been observed in many cities in Canada and around the world - with wide-ranging effects. This phenomenon does not just happen in socioeconomically disadvantaged regions of a city, and once it begins it can rapidly expand.

Now, a new deep-mapping computer model created by Professor Michael Sawada and students Lazar Ilic and Amaury Zarzelli of the Department of Geography, Environment & Geomatics  the University of Ottawa can detect visible changes to individual properties, allowing them to track gentrification more rapidly within neighborhoods and cities.
