Almost all climate scientists agree that actions must be taken to lower carbon emissions, also known as greenhouse gases, to reduce the risk of damage to the environment and ultimately human health. A group of researchers say adding carbon labels to products could help change purchasing behavior and corporate supply chains, ultimately leading to large emissions reductions. They propose a private labeling system to fill the gap until national and international rules are adopted.

But now, American and Canadian researchers report that climate change is causing wildfires to burn more widely and severely, turning Alaska's black spruce forests from carbon repositories to generators of it.
With global warming comes increased levels of carbon dioxide in the atmosphere, which benefits at least one species—weeds. Carbon dioxide acts as a fertilizer to invasive exotic grasses, resulting in higher growth rates and larger leaves.
A new study has identified a troubling change in long-term coral growth patterns on the world’s second largest barrier reef. The findings suggest that corals closest to the open ocean — and furthest from traditional land-based threats — are having the most trouble coping with environmental stress, from sources such as climate change and pollutants.

Wolverine habitat in the northwestern United States is likely to warm dramatically if society continues to emit large amounts of greenhouse gases, according to new computer model simulations carried out at NCAR. The study found that climate change is likely to imperil the wolverine in two ways: reducing or eliminating the springtime snow cover that wolverines rely on to protect and shelter newborn kits, and increasing August temperatures well beyond what the species may be able to tolerate.
The year 2010 finished in a photo finish with 1998 for the warmest year in the 32-year satellite temperature record. 2010 was only 0.013 C cooler than 1998, an amount that is not statistically significant.
The magnitude of climate change during Earth’s deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes. Building on recent research, the study examines the relationship between global temperatures and high levels of carbon dioxide in the atmosphere tens of millions of years ago.
