Climate impacts in northern forests
Northern forests hold around 54% of the world’s total terrestrial carbon stock and contribute more than one-third to our global terrestrial carbon sink. This report reviews the impact of human induced

Springtime ozone levels in the lower atmosphere over western North America are rising. The source of this pollution may be Asia, a finding that reaffirms the need for international air-quality control.
Cooler North American temperatures in 2008 resulted from a strong natural effect, and the overall warming trend that has been observed since 1970 is likely to resume, according to this study. Using computer-generated models as well as observations, the team analyzed causes for climate variations in the recent decades. Special emphasis was given to the reasons for North American coolness in 2008.

Detailed studies of ancient climate have revealed that the onset of Europe's "Big Freeze", 13,000 years ago, was anything but glacial.
<p>What do periods of weak low-latitude rainfall have to do with the meltdown of great ice sheets? Cheng <em>et al.</em> show that this counterintuitive association contains a hot clue about the much-debated causes of the ice age cycles that end every 100,000 years or so in a collapse of the great Northern Hemisphere ice sheets (a glacial termination).
Producing food simply to dump it is a waste of land, water, energy required for growing, processing and transporting it. Tristram Stuart,author of the recently published book, Waste, Uncovering the Food Scandal, shows how the way we live has created a global food crisis and how simple it would be to fix it. Kaushik Das Gupta spoke to him over phone. Excerpts On the enormity of the problem

They may explain the mystery of bee disappearance in late 2006, a third of all bee colonies in North America saw their worker bees disappear. Scientists called this abnormality colony collapse disorder, or ccd. It hit hard industries dependent on honeybees, and its cause is not yet established. Everything from the Varroa mite and viruses to pesticides and malnutrition has been
In this Review we delve into the underlying causes of health disparities between Indigenous and non-Indigenous people and provide an Indigenous perspective to understanding these inequalities. We are able to present only a snapshot of the many research publications about Indigenous health. Our aim is to provide clinicians with a framework to better understand such matters.
This publication reports on the human and economic losses caused by natural disasters in 2008 with figures based on the EM-DAT database with comparisons to previous years. It asserts that although fewer disasters occurred in 2008, events had a larger impact than usual on human settlements. In 2008 once again, large numbers of persons were affected by a few natural disasters.
