It found that oxygen levels in the world’s oceans declined by roughly 2 percent between 1960 and 2010. The decline, called deoxygenation, is largely attributed to climate change, although other human activities are contributing to the problem. One example is so-called nutrient runoff, when too many nutrients from fertilizers used on farms and lawns wash into waterways.

Landmark United in Science report informs Climate Action Summit

The world’s leading climate science organizations have joined forces to produce a landmark new report for the United Nations Climate Action Summit, underlining the glaring – and growing gaps – between agreed targets to tackle global warming and the actual reality.

The report, United in Science, includes details on the state of the climate and presents trends in the emissions and atmospheric concentrations of main greenhouse gases. It highlights the urgency of fundamental socio-economic transformation in key sectors such as land use and energy in order to avert dangerous global temperature increase with potentially irreversible impacts. It also examines tools to support both mitigation and adaptation.

“The Report provides a unified assessment of the state of our Earth system under the...
