American Geophysical Union: More, bigger wildfires burning western U.S., study shows
Wildfires across the western United States have been getting bigger and more frequent over the last 30 years – a trend that could continue as climate change causes temperatures to rise and drought to become more severe in the coming decades, according to new research.

International Institute for Applied Systems Analysis (IIASA): Nutrient-rich forests absorb more carbon
The ability of forests to sequester carbon from the atmosphere depends on nutrients available in the forest soils, shows new research from an international team of researchers. “This paper produces the first evidence that to really understand the carbon cycle, you have to look into issues of nutrient cycling within the soil,” said one of the researchers.

University of Utah: Warm U.S. West, Cold East: A 4,000-Year Pattern: Global Warming May Bring More Curvy Jet Streams during Winter
Last winter’s curvy jet stream pattern that brought mild temperatures to western North America and harsh cold to the East became more pronounced 4,000 years ago, and may become more extreme as Earth’s climate warms. By examining oxygen isotope ratios in lake and cave sediments, University of Utah researchers were able to determine several thousand years of past jet stream patterns.

Environment360: UN Panel Looks to Renewables as the Key to Stabilizing Climate
In its latest report, the UN’s Intergovernmental Panel on Climate Change makes a strong case for a sharp increase in low-carbon energy production, especially solar and wind, and provides hope that this transformation can occur in time to hold off the worst impacts of global warming.
