This state of the environment (SOE) report is a companion volume to the federal science assessment entitled "Nutrients and their impact on the Canadian enviornment", which was authored by Patricia Chambers, et al. This state of the environment (SOE) report on nutrients looks at how the Canadian environment is being affected by nitrogen and phosphorus compounds that are released as a result of human activities. The report describes the mechanisms by which nutrients affect the environment, assesses their impact on the environment especially through enrichment, and their potential for future damage, and outlines the major sources of these compounds. It also looks at what has been done and what can be done to alleviate these problems.

The current warming trends in the Arctic may shove the Arctic system into a seasonally ice-free state not seen for more than one million years. The melting is accelerating, and researchers were unable to identify natural processes that might slow the deicing of the Arctic. Such substantial additional melting of Arctic and Antarctic glaciers and ice sheets would raise the sea level worldwide, flooding the coastal areas where many of the world's population lives. Studies, led by scientists at the National Center for Atmospheric Research (NCAR) and the University of Arizona, show that greenhouse gas increases over the next century could warm the Arctic by 3-5°C in summertime. Thus, Arctic summers by 2100 may be as warm as they were nearly 130,000 years ago, when sea levels eventually rose up to 6 m higher than today.
