Interesting blog posting by Professor Paul Wapner of American University on teaching climate geoengineering, on the Washington Geoengineering Consortium website, which is a great source for all things geoengineering!
Recent studies make it increasingly clear that the globe is poised to blow past the 2°C “guardrail” that climate scientists and Parties to the UNFCCC have identified as critical to avoid dangerous climatic impacts, with current projections of temperature increases of 3-4°C or more by the end of the century. Such sobering scenarios have intensified interest in climate geoengineering options, including… Continue reading
As any climate change instructor knows, China’s ability to arrest its burgeoning emissions of greenhouse gas emissions is critical if the globe is to avoid passing critical climatic thresholds. China’s greenhouse gas emissions have risen an astounding 280% since 1990. The nation’s share of the world’s greenhouse gas emissions has now reached 28%, double that of the next highest country, the United States. Its projected 10.4 billion tons of carbon… Continue reading
A new study in the journal Environmental Research Letters assesses the potential impacts of cumulative emissions from existing fossil fuel plants built in the past few years (2010-2012). During this period, an average of 89 gigawatts of new coal generating capacity was added annually, with natural gas trends soaring at a similar pace during this time. The study by Steven J. Davis and Robert H. Socolow, sought to quantify what… Continue reading
I am planning to do a summary of the latest report from the Global Carbon Project, reflecting the work of 88 academics from 68 organizations in 12 countries. However, I also wanted to share a nice compilation of some of the key charts from the project prepared by Lindsay Wilson on The Energy Collective site. The charts include greenhouse gas emissions trends, State contributions, and the current role… Continue reading
There’s an excellent summary of a new study in the Journal of Geophysical Research: Atmospheres, which provides the most high resolution map ever of greenhouse gas emissions. The researchers produced global maps of emissions at a resolution of 0.1° latitude and longitude (about 11 kilometers at the equator) for 1997 through 2010, drawing upon national emissions reporting and key indicators for each grid including population density, economic… Continue reading
There’s an excellent new interactive graphic on the site Inside Climate News. The graphic examines 14 carbon “hot spots,” i.e. sites with very large reserves of coal, oil and natural gas, and the implications for the Earth’s carbon budget vis-a-vis our goal of limiting temperatures to below critical thresholds. The graphic facilitates looking at each site, the threat they pose to breaking the carbon budget, and the key decision-makers… Continue reading
Instructors in climate change courses looking for the latest statistics on greenhouse gas emissions (including its implications for ocean acidification, the “other” CO2 problem) should check out the World Meteorological Organization’s September Greenhouse Gas Bulletin.
Among the primary findings in the Bulletin:
1. Total radiative forcing in the NOAA Annual Greenhouse Gas Index was 34% higher at the end… Continue reading
Instructors who include a module on climate science might want to draw upon a new study in the journal Climate Risk Management. The study addresses one of the most frequent question of students, as well as the general public: could current warming trends (through July 2014, consecutive months in which global land and ocean temperatures have exceeded the 20th… Continue reading
