Fighting Black Carbon as Oceans & Temperatures Rise

Scripps Institution of OceanographyLast 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.

LongreadsSatellite images of Beijing’s smog have been popping up on Twitter and blogs as the city suffers shockingly high air pollution levels. Some bloggers point out Beijing’s black skies aren’t so different from pre-1960s London or Pittsburgh in their industrial heyday. Even so, a new study warns that the heat-trapping effect of “black carbon,” or soot, is second only to CO2. Yale’s Environment 360 explains why cutting it could “go a long way to slowing climate change.” Check out cities with high air pollution levels in the Guardian’s data visualization showing exposure to outdoor air pollution, mapped by city.

Concern over the brutal and fatal rape of a young woman in India continues to grow. Former UK Prime Minister Gordon Brown highlights a global online petition that has attracted more than a million signatures in “Without frontiers, young people mobilize for change.” On Twitter, plans for a February 14 worldwide event to raise awareness about violence against women are being spread using hashtag #1billionrising, For an academic read on the issue, check out a recent study, linked below, on combating violence against women, covering 40 years and 70 countries. It finds that the “mobilization of feminists…is the critical factor accounting for policy change.” What will the world be like 17 years from now? A new report by the National Intelligence Council -- Global Trends 2030 (pdf) -- is sparking interest. Harvard University Distinguished Service Professor Joseph S. Nye offers his take on the report’s “gamechangers” and megatrends. One key trend—urbanization—is keenly felt in Nairobi. The city’s Kibera slum is a place where “government is absent,” and where the economy is booming and incomes are rising, according to the Economist, adding it “may be the most entrepreneurial place on the planet.
