On Tuesday, the Australian senate passed legislation that will set a price on carbon and help meet its emissions targets.
Part 2: Challenges
This piece was written in collaboration with Cui Xueqin, Fu Sha, and Zou Ji.
In 2009, China’s Twelfth Five-Year Plan set a goal to cut the country’s carbon intensity by 17 percent by 2015. Responsibility for achieving portions of this target has been allocated to provinces and cities. This three-part series explores the vital role of China’s municipalities in reaching the national carbon intensity goal. Part 1 presented low-carbon city targets and plans developed to date. Part 2 explores some challenges related to designing city-level low-carbon plans and mechanisms to track progress towards them. Part 3 will present some possible solutions to these challenges.
Despite the work by major Chinese cities to move city planning onto a low-carbon trajectory, several challenges remain. Notable among these are the unclear relationship between low-carbon city planning and other planning processes, a lack of methods to account for city-level greenhouse gas (GHG) emissions, and a lack of approaches to address GHG emissions from electricity transmission.
East Coast snowstorms in October. The suburbs of Bangkok under water. Extreme droughts in the Horn of Africa.
Such "freak" weather events have dominated headlines for over a year, and with good reason.
Now, a new report from the International Panel on Climate Change (IPCC) is making the connections between these extreme weather events and climate change.
Snaking across multiple international boundaries and supporting everything from villages and farms to industry and cities, the Orange-Senqu River is one of the most important natural resources in southern Africa. The complexity and significance of the Orange-Senqu basin made it a clear focus for the Aqueduct project, which aims to measure and map physical, reputational, and regulatory water risks in economically important river basins around the world.
With a prototype map for the Yellow River basin in China and global water stress maps completed, the World Resources Institute (WRI) is in the process of expanding its basin-level mapping into other basins around the world, including the Orange-Senqu.

A third of Thailand is under water. Epic floods have taken people's lives, destroyed businesses and crops, and are now sweeping into Bangkok.
As the capital braces itself, some people are beginning to point fingers at various culprits: the unusually heavy rains possibly linked to climate change, ineffective communications within government, and poor infrastructure decisions.
Today, WRI releases a new map that identifies the hotspots where urban and suburban development are putting forests at risk in the southern United States. Areas experiencing the most forest loss to development between 2001 and 2006 (the most recent years for which data are available) were counties near Houston, Atlanta, Raleigh, and Charlotte. Counties around San Antonio, Jacksonville, and Birmingham round out the “top ten” (Table 1).
On October 20, I spoke at an Interactive Dialogue of the UN General Assembly about the imminent report of the High Level Panel for Global Sustainability. The Panel, convened by Secretary-General Ban Ki-moon, is charged with articulating a new vision for sustainable growth and prosperity. Its report, due at the end of 2011, will set the tone for intergovernmental action in the coming years, including at the 2012 Rio+20 Earth Summit.
With a roster of current and former world leaders (including Mrs. Tarja Halonen, President of Finland and Mr. Jacob Zuma, President of South Africa) the Panel is uniquely positioned to set an agenda for green growth and prosperity. As I say in my remarks below, we already know what we need to do to promote sustainability. The real question lies in how to move forward and overcome both the political and behavioral hurdles that have hampered progress so far. Can the Panel craft a vision that is ambitious, politically realistic, and persuasive to the larger public?
If you believe the doomsday merchants, the scariest thing about this Halloween is the fact that the world's population will pass seven billion on or near October 31.
Population growth, however, is not the biggest skeleton in the closet when it comes to our planet's ability to absorb human impact. Far more damaging than the booming birth rate in low income countries are the resource-intensive lifestyles of the global rich and middle class.
Denmark’s new coalition government, elected last month, has adopted a new, more ambitious climate policy committing the country to reduce its GHG emissions by 40% from 1990 levels by 2020 through domestic action. This target brings Denmark into line with the level of reduction proposed by the Intergovernmental Panel on Climate Change (IPCC), as well as with the targets of several other Nordic and Northern European countries.
Climate skeptics have denounced studies of temperature rise because of alleged biases in data sets. So in an effort to get to the bottom of these critiques, a group of scientists launched the Berkeley Earth Surface Temperature study, using different methods with skeptics’ arguments in mind. Its findings are in, and they confirm that not only is the Earth’s land temperature warming, but the results mimic the very results of previous assessments that the skeptics had tossed aside.
