New research by UM bioclimatology Assistant Professor Ashley Ballantyne models the influence of Arctic sea ice on Arctic temperatures during the Pliocene era.
A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth's atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.
Southern pines appear to grow and conserve water somewhat better in the carbon-dioxide-enriched atmosphere expected by mid-century, a Duke University study has found. However, any growth spurts appear to diminish over time, due at least in part to the kind of hot and dry weather that likely may become more common in the future. Thus, the researchers concluded, enhanced growth of pines may not constitute a long-term sink for human-produced carbon dioxide which might ameliorate global warming.
