Though governments have agreed to try to limit global warming to no more than two degrees Celsius above pre-industrial levels, a paper by James Hansen et al. in Atmospheric Chemistry and Physics finds that goal may not prevent major changes on an irreversible and unadaptable scale. Studying the last interglacial period, about 120,000 years ago, when the temperature was less than one degree Celsius warmer than today, Hansen et al. estimate sea level was six to nine meters higher than today.

In December 2015, representatives from 195 nations gathered in Paris for the 21^st Conference of the Parties (COP-21) to the UN Framework Convention on Climate Change. After two weeks of intensive negotiations, countries approved an agreement that charts new territory for global cooperation to address climate change. [Video Below]

The world is entering a new phase of climate change defined by “failure to mitigate sufficiently and failure to adapt sufficiently,” said Saleemul Huq, director of the Bangladesh-based International Center for Climate Change and Development, at the Wilson Center on March 16. [Video Below]

When anyone wishes to support – or defeat – a given position, the sturdiest method is to generate data to predict its consequences. Advocates generate reams of numbers to substantiate their preferred outcome.

Developing countries are in a pitched fight against the effects of climate change, and women, playing prominent roles in agriculture and household resource collection, are “at the front lines in the battle,” writes UN Framework Convention on Climate Change Executive Secretary Christiana Figueres, in a new report.

A study published by the Proceedings of the National Academy of Sciences projects future sea-level rise with a new model, providing crucial information for coastal planning and further impetus to cut carbon emissions. Sifting through data on thermal expansion and retreating glaciers, the two leading causes of sea-level rise in the past century, the authors confirm that sea level is rising at an unprecedented rate.

A four-part video series produced by the Kenya Broadcasting Corporation (KBC) and supported by the Fund for Investigative Journalism gives an update on the beleaguered communities of Lake Turkana, the world’s largest desert lake that supplies vital ecosystem services and livelihoods to 300,000 people in northwestern Kenya. The lake is fed entirely by the Omo River, flowing south from Ethiopia, but a newly completed upstream dam has raised questions about the future.
