Enhancing Nationally Determined Contributions through Protected Areas

This report of WWF US shares the evaluation of Nationally Determined Commitments (NDCs) to the United Nations Framework Convention on Climate Change 2015 Paris Agreement. These NDCs emphasize the role protected areas and other conserved areas play in the achievement of global mitigation and adaptation targets. By reviewing the 151 currently available NDCs, this report determines how parties intent to use protected areas to contribute to climate challenges.

Diving enthusiasts could be used to measure ocean temperatures

Millions of holidaying scuba divers are able to become citizen scientists and take vital measurements of ocean temperatures, which are being driven up by climate change.

More than 90% of the heat trapped by global warming goes into oceans, where it drives hurricanes and disrupts fish stocks. Satellites can measure surface temperature when there are no clouds, but getting data from below the surface is much harder and more expensive.

Transforming management of tropical coastal seas to cope with challenges of the 21st century

Over 1.3 billion people live on tropical coasts, primarily in developing countries. Many depend on adjacent coastal seas for food, and livelihoods. We show how trends in demography and in several local and global anthropogenic stressors are progressively degrading capacity of coastal waters to sustain these people. Far more effective approaches to environmental management are needed if the loss in provision of ecosystem goods and services is to be stemmed.

Biophysical principles for designing resilient networks of marine protected areas to integrate fisheries, biodiversity and climate change objectives in the Coral Triangle

These guidelines have an integrated approach on designing MPA networks, including the interests of fisheries, biodiversity and climate change. Instead of that the MPA network establishers were not focusing on one single objective and interest, they include sustainable fishery objectives, biodiversity conservation and ecosystem resilience.

Cumulative effects of planned industrial development and climate change on marine ecosystems

With increasing human population, large scale climate changes, and the interaction of multiple stressors, understanding cumulative effects on marine ecosystems is increasingly important. Two major drivers of change in coastal and marine ecosystems are industrial developments with acute impacts on local ecosystems, and global climate change stressors with widespread impacts. We conducted a cumulative effects mapping analysis of the marine waters of British Columbia, Canada, under different scenarios: climate change and planned developments.

Contrasting futures for ocean and society from different anthropogenic CO2 emissions scenarios

The ocean moderates anthropogenic climate change at the cost of profound alterations of its physics, chemistry, ecology, and services. Here, we evaluate and compare the risks of impacts on marine and coastal ecosystems—and the goods and services they provide—for growing cumulative carbon emissions under two contrasting emissions scenarios. The current emissions trajectory would rapidly and significantly alter many ecosystems and the associated services on which humans heavily depend.

Environmental systemic risk & insurance white paper

This paper outlines what environmental systemic risk is and why it is an issue of increasing importance. It suggests the impacts it has on insurers but also the barriers which exist to an industry response. Finally it makes recommendations as to the ways the insurance sector as a whole, as well as individual companies can respond. It is designed to facilitate further discussion and debate on the approach to better mitigation and effective pricing of new risk classes.

Blue Carbon: A new concept for reducing the impacts of climate change by conserving coastal ecosystems in the Coral Triangle

This repport is aimed at politicians, governments, businesses and organisations that influence the development of policies and strategies in climate change mitigation and adaptation, poverty alleviation, natural resource use, biodiversity conservation and economics. It's aim is to stimulate discussion and debate on how to promote and utilise healthy coastal ecosystems and the valuable benefits they provide to support a sustainable and more climate resilient future for communities within the Coral Triangle.
