Climate Change May Be Creating A Seafood Trade War, Too

June 15th, 2018, Marshall Shepherd, Forbes.com

One of the grand challenges that I find as a climate scientist is conveying to the public the “here and now” of climate change. For many people, it is still some “thing” that seems far off in time or distance from their daily lives of bills, illness, kids, and their jobs. Ironically, climate change touches each of those aspects, but the average person does not often make the connections. People eat seafood and fish, but most people will not make any connections between tonight’s dinner of flounder, lobster or mackerel to climate change as they squeeze that lemon or draw that butter.

A new Rugters University study caught my eye because it is a good example of a “here and now” impact. Climate changes is causing fish species to adjust their habitats at a more rapid pace than current policy can manage. Many species of flounder, lobster, mackerel and crab are migrating to find colder waters as oceans warm.  The study suggests that such shifts may lead to international conflict and reductions in fish supply. Seafood is a pawn in the trade chess game.

Fishers on deck

Researchers at Rutgers University say that an obsolete and outdated regulatory system has not kept pace with how the ocean’s waters are warming and shifting fish populations. I actually wrote a few years ago in Forbes about how warming waters were shifting crab populations in the North Pacific and affecting fishers as well as one of my favorite TV shows, The Deadliest Catch. This new study published in one of the top scientific journals in the world, Science, has provided new insight that has implications for our food supply and potential international conflict. According to a press release from the university:

for the first time that new fisheries are likely to appear in more than 70 countries all over the world as a result of climate change. History has shown that newly shared fisheries often spark conflict among nations. Conflict leads to overfishing, which reduces the food, profit and employment fisheries can provide, and can also fracture international relations in other areas beyond fisheries. A future with lower greenhouse gas emissions, like the targets under the 2015 Paris climate agreement, would reduce the potential for conflict, the study says.

Malin Pinsky is an assistant professor of ecology, evolution and natural resources at Rutgers and one of the authors of the study. He, postdoctoral associate James Morley and a group of international co-authors reported that commercially important fish species (in other words things you like to eat and that many depend on for sustenance) could continue to migrate further northward in search of colder waters.

China’s emissions reversal cause for ‘cautious optimism,’ says study

July 2, 2018, University of East Anglia

The decline in China’s carbon emissions is likely to be sustained if changes to the country’s industrial structure and energy efficiency continue, according to new research led by the University of East Anglia (UEA).

As part of the Paris Agreement, China pledged to peak its CO2 emissions by 2030. In fact, China may already have fulfilled this commitment, with emissions peaking in 2013 at a level of 9.5 Gigatons of CO2, and declining in each year from 2014 to 2016.

After nearly two decades of rapidly rising emissions the study, published in Nature Geoscience, shows that slowing economic growth in China has made it easier to reduce emissions. The decline of 4.2% in the years since to 2016 is largely associated with changes in industrial structure and a decline in the share of coal used for . Decreasing energy intensity (energy per unit GDP) and emissions intensity (emissions per unit energy) also contributed to the decline.

The study authors say the peak prompts important questions about what factors are driving the current decrease, their relative importance, and whether or not the decline can be sustained or even accelerated. In particular, if China’s emissions are have fallen primarily as a result of slowing economic activity, as happened in the US during the global financial crisis, renewed  could reverse the decrease.

The team from UEA, the University of Cambridge and UCL, together with researchers in China and the US, explored this by assessing the drivers of Chinese CO2 emissions from 2007-2016, using the latest available energy, economic, and industry data.

They warn that China’s emissions may fluctuate in the coming years and that may mean that 2013 may not be the ‘final’ peak. Indeed, preliminary figures for 2017 have shown an increase. However, the changes in industrial activities, coal use, and efficiency that have caused the recent decline have roots in the changing structure of China’s economy and long-term government policies.
