Tuesday, September 13,, 2016 — Using software tools developed by Near Zero, a research group hosted by the
DGE, a team of researchers has completed the largest expert survey yet on any energy technology, in this case wind energy.
Near Zero conducts research and assessment of energy and climate issues, focusing on integrating quantitative analysis with expert judgment. In this way, they inform decision-making to accelerate the global transition to a near-zero emission energy system. To support this work, Near Zero has developed open-source software tools to examine where experts agree and disagree and why. more »
Monday, September 5, 2016— One of the world’s longest-running, most comprehensive climate change experiments produced some surprising results. The extensive experiment subjected grassland ecosystems to sixteen possible future climates and measured many aspects of ecosystem performance and sustainability. This study, appearing in the September 5, 2016, Early Online Edition of the Proceedings of the National Academy of Sciences, reports on 17 years of plant growth, an important bellwether of ecosystem health. Plant growth varied tremendously from year to year, reaching a peak under conditions near the average over the last several decades. As conditions move away from the averages, as happens with climate change, plant growth fell. more »
Friday, August 12, 2016 — Well-understood physical and chemical processes can easily explain the alleged evidence of a secret, large-scale atmospheric spraying program, commonly referred to as “chemtrails” or “covert geoengineering,” concludes a new study from DGE, University of California Irvine, and the nonprofit organization Near Zero.
Some groups and individuals erroneously believe that the long-lasting condensation trails, or contrails, left behind aircraft are evidence of a secret large-scale spraying program. They call these imagined features “chemtrails.” Adherents of this conspiracy theory sometimes attribute this alleged spraying to the government and sometimes to industry. more »
Friday, August 5, 2016—Offering a rare insider analysis of the climate assessment process, Katharine Mach and colleagues at the Department of Global Ecology examined the writing and editing procedures by which the Intergovernmental Panel on Climate Change creates summaries of their findings for policymakers. Despite recent critiques that these summaries are too difficult for non-experts, Mach and colleagues found them comparable to reference texts in terms of reading comprehension level. Their results are published by Science Advances. more »
