Sensitivity of boreal forest carbon balance to soil thaw

by M. L. Goulden, S. C. Wofsy, J. W. Harden, S. E. Trumbore, P. M. Crill, S. T. Gower, T. Fries, B. C. Daube, S. -m. Fan, D. J. Sutton, A. Bazzaz, J. W. Munger - Science , 1998
"... We used eddy covariance; gas-exchange chambers; radiocarbon analysis; wood, moss, and soil inventories; and laboratory incubations to measure the carbon balance of a 120-year-old black spruce forest in Manitoba, Canada. The site lost 0.3 6 0.5 metric ton of carbon per hectare per year (ton C ha21 ye ..."

Extreme melt on Canada’s Arctic ice caps in the 21st century

by Claude Labine, J. G. Cogley, M. Ecclestone, C. Labine, G. J. Wolken
"... Earth’s glacier and ice cap area. Snow accumulation on these glaciers is low and varies little from year to year. Changes in their surface mass balance are driven largely by changes in summer air temperatures, surface melting and runoff. Relative to 2000–2004, strong summer warming since 2005 (1.1 t ..."

.1 to 1.6°C at 700 hPa) has increased summer mean ice surface temperatures and melt season length on the major ice caps in this region by 0.8 to 2.2°C and 4.7 to 11.9 d respectively. 30–48 % of the total mass lost from 4 monitored glaciers since 1963 has occurred since 2005. The mean rate of mass loss

Diabetes Care in the U.S. and Canada

by Gillian L. Booth, Bernard Zinman Md, Donald A. Redelmeier
"... OBJECTIVE — To compare the glycemic control of patients with type 1 diabetes treated in the U.S. and Canada. RESEARCH DESIGN AND METHODS — A large multicenter randomized clinical trial conducted in the U.S. and Canada was analyzed. Patients with type 1 diabetes, screened from 1983 to 1989 for enroll ..."

for enrollment in the Diabetes Control and Complications Trial (DCCT), were categorized as treated in the U.S. (n 2,604) or Canada (n 245). HbA1c levels were compared between U.S. and Canadian patients, both before and after adjustment for predictors of HbA1c. RESULTS — In general, volunteers screened
