Energy Collective: The World Meteorological Organization reports that, for the first time in human history, atmospheric concentrations of carbon dioxide (CO2) eclipsed 400 parts-per-million (ppm) in the northern hemisphere for the entire month of April. CO2 concentration vary with the seasons, generally reaching their highest level early in the northern hemispheres spring before seasonal intake of CO2 from vegetation. The first recording of 400 ppm occurred briefly in the spring of 2012 at the National Oceanic and...

RTCC: World leaders are running out of time to address the threat of climate change, the UNs chief meteorologist warned as carbon dioxide levels hit record highs in April. Data released by the World Meteorological Organization (WMO) revealed that for the first time CO2 topped 400 parts per million (ppm) in April throughout the northern hemisphere. WMO Secretary-General Michel Jarraud said the findings had symbolic and scientific significance, adding it should serve as a wake-up call over the...
Should we try to fight rising sea levels - or abandon the coasts?

Vox: The world's sea levels are expected to rise 1 to 3 feet -- or more -- as the planet heats up in the coming century. The more greenhouse gases we emit, the bigger the rise, but we've already locked in at least some sea-level increase no matter what. So what should the millions of people living in low-lying coastal areas do? Broadly speaking, there are three ways to deal with sea-level rise. First, large coastal cities like New York or Boston or Tokyo will likely spend billions to erect dikes...

National Public Radio: Last week, scientists warned that a massive chunk of the West Antarctica Ice Sheet will eventually drift into the sea and melt, raising sea levels at least 10 feet higher than previous predictions. Even before the announcement, scientists at the nonprofit research organization Climate Central predicted that surging seas could put the homes of nearly 5 million Americans underwater by the end of this century. Dawn Zimmer, mayor of Hoboken, N.J., is a member of President Obama's Task Force on...
