Climate Changes

Several stories on the science and politics of global warming caught our attention this week:

Continued levels of environmental damage could threaten the world’s oceans and leave them at high risk of a mass extinction of marine species unprecedented in human history, according to a recent inter-disciplinary study by marine scientists from around the world. The main causes of this extinction would be global warming, ocean acidification and a lack of oxygen. For instance, acidification is occurring faster than in the past 55 million years, and with the added man-made stressors of overfishing and pollution, undermining ocean resilience, it found.

The rate of sea level rise along the U.S. Atlantic Coast is greater now than at any time in the past 2,000 years, according to findings published in the journal Proceedings of the National Academy of Sciences. “Sea-level rise is a potentially disastrous outcome of climate change as rising temperatures melt land-based ice, and warm ocean waters,” the findings say.

Australian research institute Commonwealth Scientific and Industrial Research Organization launched a website that shows a steady increase in greenhouse gas emissions over the past three decades. The data is taken from monthly readings at a baseline air pollution station in Tasmania overseen by the World Meteorological Organization-Global Atmosphere Watch network.
