(Rune Stoltz Bertinussen/NTB scanpix/Reuters) Hundreds of scientists from several countries have now embarked on two simultaneous and related research projects in the Arctic. The yearlong project involves a research ship which will drift with the ice and a land-based operation. It's called the Multidisciplinary drifting Observatory for the Study of Arctic Climate, or MOSAiC , while the land based project is called T-MOSAIC, the T is for terrestrial. Levon spoke with Warwick Vincent, a polar scientist and Canada Research Chair at Université Laval in Quebec City. Massive loss of N. American birds: study The Canadian study showed as an example that 2 in 5 Baltimore Orioles (shown) have disappeared as have 2 in 5 barn swallows. (Gary Mueller-Macaulay Library-Cornell Lab of Ornithology) The morning chorus of birds in N.America is not what it used to be. A new study points to why that is. The study analysed recent bird population data, and compared it to that of several decades ago. They found that there are about 3 billion birds fewer now that there were in 1970.

The ReDirect program in Calgary is one of them. (Andrew Vaughan/Canadian Press) A programme in Calgary, Alberta seeks to connect with young people and steer them away from gangs and violence. It's part of a larger effort both nationally and by individual cities to prevent both radicalization and gang violence. It's called "Re-direct" and involves city social workers and police. Terry spoke with programme co-ordinator is Sgt. Gareth Joels of the Calgary Police Service. The LINK show Sept. 27. 2019
