Washington, DC— The climate models that project greater amounts of warming this century are the ones that best align with observations of the current climate, according to a new paper from Carnegie’s Patrick Brown and Ken Caldeira published by Nature.  Their findings suggest that the models used by the Intergovernmental Panel on Climate Change, on average, may be underestimating future warming.

Climate model simulations are used to predict how much warming should be expected for any given increase in the atmospheric concentration of carbon dioxide and other greenhouse gases.

“There are dozens of prominent global climate models and they all project different amounts of

Washington, DC— About 40 percent of northern Malaysian Borneo’s carbon stocks exist in forests that are not designated for maximum protections, according to new remote sensing and satellite mapping from Carnegie’s Greg Asner and his colleagues.

Asner’s flying laboratory, the Carnegie Airborne Observatory, was able to map carbon stocks that—together with satellite imaging and other geospatial data—will guide conservation efforts undertaken by the Sabah Forestry Department in Malaysian Borneo, the Southeast Asia Rainforest Research Partnership (SEARRP), the PACOS Trust, BC Initiative and other organizations.

Washington, DC— There is considerable opportunity for generating wind power in the open ocean, particularly the North Atlantic, according to new research from Carnegie’s Anna Possner and Ken Caldeira. Their work is published by Proceedings of the National Academy of Sciences.

Because wind speeds are higher on average over ocean than over land, wind turbines in the open ocean could in theory intercept more than five times as much energy as wind turbines over land. This presents an enticing opportunity for generating renewable energy through wind turbines. But it was unknown whether the faster ocean winds could actually be converted to increased amounts of electricity.

In March 2014, a technical support unit (TSU) of ten, headquartered at Global Ecology, had successfully completed a herculean management effort for the 2000-page assessment Climate Change 2014: Impacts, Adaptation, and Vulnerability, including two summaries. They were issued by the United Nations (UN) Intergovernmental Panel on Climate Change (IPCC), Working Group II co-chaired by Chris Field, Global Ecology director, with science co-directors Katie Mach and Mike Mastrandrea managing the input of over 190 governments and nearly 2,000 experts from around the world.

The IPCC, established in 1988, assesses information about climate change and its impacts. In September 2008, Field was

Anna Michalak’s team combined sampling and satellite-based observations of Lake Erie with computer simulations and determined that the 2011 record-breaking algal bloom in the lake was triggered by long-term agricultural practices coupled with extreme precipitation, followed by weak lake circulation and warm temperatures. The bloom began in the western region in mid-July and covered an area of 230 square miles (600 km2). At its peak in October, the bloom had expanded to over 1930 square miles (5000 km2). Its peak intensity was over 3 times greater than any other bloom on record. The scientists predicted that, unless agricultural policies change, the lake will continue to experience

Carnegie researchers are developing new scientific approaches that integrate phylogenetic, chemical and spectral remote sensing perspectives - called Spectranomics - to map canopy function and biological diversity throughout tropical forests of the world.

Mapping the composition and chemistry of species in tropical forests is critical to understanding forest functions related to human use and climate change. However, high-resolution mapping of tropical forest canopies is challenging because traditional field, airborne and satellite measurements cannot easily measure the canopy chemical or taxonomic variation among species over large regions. New technology, such as the Carnegie

Coral reefs are havens for marine biodiversity and underpin the economies of many coastal communities. But they are very sensitive to changes in ocean chemistry resulting from greenhouse gas emissions, as well as to pollution, warming waters, overdevelopment, and overfishing. Reefs use a mineral called aragonite, a naturally occurring form of calcium carbonate, CaCO3, to make their skeletons.  When carbon dioxide, CO2, from the atmosphere is absorbed by the ocean, it forms carbonic acid—the same stuff that makes soda fizz--making the ocean more acidic and thus more difficult for many marine organisms to grow their shells and skeletons and threatening coral reefs globally.

Field has authored more than 200 scientific publications and is cochair of the U. N.'s Intergovernmental Panel on Climate Change (IPCC) Working Group 2. The IPCC Fourth Assessment, for which Field was a coordinating author, was published in 2007. He was coeditor of the March 2012 IPCC Special Report on Managing the Risks of Extreme

Anna Michalak joined Carnegie in 2011 from the Department of Civil and Environmental Engineering at the University of Michigan. Her research focuses on characterizing complexity and quantifying uncertainty in environmental systems to improve our understanding of these systems and our ability to forecast their variability. She is looking at a variety of interactions including atmospheric greenhouse gas emission and sequestration estimation, water quality monitoring and contaminant source identification, and use of remote sensing data for Earth system characterization.

The common theme of her research is to develop and apply spatiotemporal statistical data methods for optimizing the
