Gauging Economic Consensus on Climate Change

Peter Howard & Derek Sylvan, Institute for Policy Integrity Energy Solutions

Thousands of economists have spent years or decades studying the interaction between climate change and the economic systems that underlie modern life. The views of these experts can help clarify how climate change will likely affect our society and economy, and how policymakers should approach greenhouse gas emission reduction efforts.

Ocean Knowledge for a Sustainable Ocean Economy: Synergies between the Ocean Decade and the Outcomes of the Ocean Panel

IOC-UNESCO

A recent analysis prepared by IOC-UNESCO explores tangible ways in which linkages between the Ocean Decade, with its vision of the ‘science we need for the ocean we want’, and the Ocean Panel, with its aims of ‘safeguarding the long-term health and resilience of the ocean’, can be leveraged and optimized.

Red seaweed (Asparagopsis taxiformis) supplementation reduces enteric methane by over 80 percent in beef steers

Roque, BM et al., PLoS ONE Energy Solutions Fisheries & Aquaculture

Livestock production, particularly ruminants, contributes to anthropogenic greenhouse gas (GHG) emissions globally. These emissions are estimated to be 7.1 Gt carbon dioxide (CO2) equivalents annually which accounts for approximately 14.5% of the global anthropogenic GHG emissions. The majority of GHG emissions from livestock production is in the form of methane (CH4), which is produced largely through enteric fermentation and to a lesser extent manure decomposition.

UNESCO Marine World Heritage: Custodians of the globe's blue carbon assets

Duarte, C.M. et al., UNESCO

Over the last decades scientists have discovered that seagrass meadows, tidal marshes, and mangroves – “blue carbon” ecosystems – are among the most intensive carbon sinks in the biosphere. By sequestering and storing significant amounts of carbon from the atmosphere and ocean, blue carbon ecosystems help mitigate climate change. But conversion and degradation of these ecosystems can also release billions of tons of CO2 and other greenhouse gases into the ocean and atmosphere and contribute to global warming.

Report on the Ocean Acidification Crisis in Massachusetts

Massachusetts Ocean Acidification Commission Fisheries & Aquaculture

Since the industrial revolution, the world’s oceans have become increasingly acidic. The main drivers of ocean acidification in Massachusetts are (1) global increases in atmospheric carbon dioxide resulting from anthropogenic emissions, and (2) local nutrient pollution leading to the eutrophication of coastal waters.

Three decades of trace element sediment contamination: The mining of governmental databases and the need to address hidden sources for clean and healthy seas

Richir, J. et al., Environment International Shipping & Ports

Trace elements (TEs) frequently contaminate coastal marine sediments with many included in priority chemical lists or control legislation. These, improved waste treatment and increased recycling have fostered the belief that TE pollution is declining. Nevertheless, there is a paucity of long-term robust datasets to support this confidence.

The Economics of Biodiversity: The Dasgupta Review

HM Treasury

Economics is a discipline that shapes decisions of the utmost consequence, and so matters to us all. The Dasgupta Review at last puts biodiversity at its core and provides the compass that we urgently need. In doing so, it shows us how, by bringing economics and ecology together, we can help save the natural world at what may be the last minute – and in doing so, save ourselves.
