12 May 2015, IIASA, Linking population and climate change: Population growth and changes in demographic structure are a key factor influencing future climate change, as well as people’s ability to adapt. People’s lifestyles and consumption habits make a huge difference in climate change projections. In a new article published in the journal Population Studies, IIASA demographers Wolfgang Lutz and Erich Striessnig describe new research linking population change with climate change scenarios. The research relies on new IIASA population projections, which include not just the numbers of people, but also the composition of populations by age, sex, and educational attainment for a number of different scenarios designed for climate research, the Shared Socioeconomic Pathways (SSPs).

11 May 2015, SCIENCEINSIDER: Antarctic researchers ponder challenges posed by increasing sea ice. Scientists working in Antarctica are feeling the impact of climate change in ways the public might find surprising. Although global warming is causing Arctic ice to melt and glaciers around the world to shrink, the problem in Antarctica is that the sea ice surrounding the continent is increasing and now hampering ship navigation and resupply operations. This week, scientists and logistics experts from the 30 nations working on the continent are meeting in Hobart, Australia, to exchange ideas on coping with the sea ice challenge. Read More here
11 May 2015, INSIDER, WRI: A Unique Proposal for a Successful Outcome in Paris: Four years ago, countries around the world committed to strike a new international climate agreement this December. The Paris climate summit comes in a year where the impacts of climate change are experienced, understood and acknowledged more than ever before. Governments, the public, investors and businesses are increasingly recognizing the economic and social consequences of climate change, from heat waves and stronger storms to forest fires and sea level rise. Meanwhile, adoption of renewable energy is growing rapidly while costs are plummeting, providing evidence that the global shift to a low-carbon economy is only a matter of time. But questions remain: Can the world form a pact in Paris this December that will accelerate the low-carbon transition at a speed and scale required to avoid the worst climate impacts? How would the different priorities and circumstances among nearly 200 countries be addressed? And just what might this historic agreement look like? Read More here
Why is oil and gas activity causing earthquakes? And can we reduce the risk? If you’ve been following the news lately, chances are you’ve heard about – or even felt – earthquakes in the central United States. During the past five years, there has been an unprecedented increase in earthquakes in the North American mid-continent, a region previously considered one of the most stable on Earth. According to a recent report by the Oklahoma Geological Survey, Oklahoma alone has seen seismicity rates increase 600 times compared to historic levels. The state has gone from experiencing fewer than two magnitude-three earthquakes per year to greater than two per day, the report found. Similarly, my home state of Texas has experienced a near 10-fold increase in magnitude-three earthquakes or greater in the past five years. Read More here
