Fighting Black Carbon as Oceans & Temperatures Rise
Last week, the Scripps Institution of Oceanography released data showing that CO2 atmospheric levels had briefly passed 400 parts per million (ppm) and were close to surpassing that level for sustained periods of time. This is bad news. At 450 ppm, scientists anticipate the world will be 2 degrees Celsius warmer than pre-industrial times, and world leaders have agreed that’s a point of dangerous consequences.
Along with this grim news came important new research findings from Professor V. Ramanathan of the Scripps Institution at the University of California, San Diego, and other researchers regarding short-lived climate pollutants – black carbon, methane tropospheric ozone and some hydrofluorocarbons (HFCs). While we continue – and must continue – to hammer away at reducing CO2 emissions, their work supports the argument that also reducing these short-lived climate pollutants (SLCPs) can have an immediate effect on slowing warming and the resulting sea-level rise.

In two weeks, economic policymakers from around the world will gather in Washington, D.C., for the World Bank-IMF Spring Meetings. As has been the case for the past five years, there will be much talk of economic crisis and of strategies to restore confidence, kick start growth, and create jobs. There is growing evidence that we are on the right track, but this agenda still requires much more work. 


Walking out of Keflavik airport as the arctic breeze hit my face at 50 km per hour, I thought to myself, “I love my job.” A job that makes a tropical citizen like me enjoy the hospitality of the very warm Icelanders and allows me to learn from their experience is hard to top. With 320,000 citizens and just the size of the U.S. state of Kentucky, subpolar Iceland has a lot to teach us development practitioners.
