International freight transport — whether by air, land, or sea — still relies overwhelmingly on fossil fuels, accounting for 30 percent of transportation-related carbon dioxide emissions and more than 7 percent of all global emissions. Experts agree that freight, and international trade more broadly, must be decarbonized if we expect to hit the Paris Agreement’s climate goals. With the world’s freight carriers deeply shaken and supply chains upturned by the Covid-19 pandemic, now is exactly the right time to begin reshaping it.

Until recently, global trade has been largely ignored in the discourse about the transition to a low-carbon economy. One reason is that it is a cross-border business, and thus largely falls outside of the emissions reduction plans of individual nations. As a result, it has escaped much of the scrutiny that other industries have faced over their carbon footprints.

In the midst of the coronavirus crisis, with so many planes grounded, ports restricted, and borders sealed, the world has a rare opportunity to make sweeping changes in the freight sector. It should jump on the chance.

Many of the world’s largest freight transporters are flailing during the pandemic and will be reliant on government money to survive. Major European airlines are cutting massive bailout deals with their governments right now. (Over one fifth of aviation’s carbon footprint stems from freight transport.) Cargo shipping and road freight are also at crossroads. As a result, governments have leverage to prod these industries to go greener and contribute their fair share to hitting international climate targets.

This might, at first, sound like a Sisyphean task. Global trade is the source of millions of jobs and diverse, inexpensive goods for consumers around the world. But there is growing recognition of freight’s centrality in the climate crisis, and there have already been tentative moves to decarbonize it — by requiring sustainable biofuel blending and better energy efficiency, as well as by shifting emissions-heavy road freight to railroads and ships. For example, in 2018 the International Maritime Organization, the U.N. agency responsible for establishing environmental standards for the shipping industry, for the first time pledged to reduce greenhouse gas emissions from international shipping to half of 2008 levels by 2050. The EU’s $1.7 billion Connecting Europe Facility will, among many other projects, bolster the continent’s rail networks and facilitate the adoption of greener fuels for all modes of transportation in the E.U., including freight carriers.

There are several ways the trade sector can continue building on this foundation.

First, governments should attach environmental conditions to any pandemic-related bailouts and loans. “The case for reconsidering the current incentive structure of transport-related policies has never been stronger,” says Olaf Merk of the International Transport Forum at the Organization for Economic Cooperation and Development.

Austria and France are already doing this with their national airlines. In Austria, government-secured loans and grants totaling more than $500 million to Austrian Airlines come with stipulations that the airline limit short-haul flights and cut its carbon emissions to 50 percent of 2018 levels by 2030. Likewise, the French government has insisted that Air France, which will collect $8.3 billion in government aid and loans, slash emissions from domestic flights by 50 percent by 2024 and buy more fuel-efficient planes. In stark contrast, Germany required nothing of the sort from Lufthansa — which owns Austrian Airlines — in exchange for its $9.9 billion rescue package.

Strings should also be attached to rescue money and loans to cargo shippers, should more require them. International shipping carries close to 80 percent of global trade and accounts for 2.5 percent of global greenhouse gas emissions. French shipping company CMA CGM has already had to take a $1.1 billion loan, backed largely by the French government but with no conditions attached. Any future loans or bailouts should hinge on the condition that shipping companies reduce the carbon intensity of their transport by at least 40 percent by 2030 compared to 2018— a hard-nosed target that goes beyond the shipping sector’s current, non-binding pledge to reduce emissions to 50 percent of 2008 levels over the same time span. Though ambitious, the target is feasible: Ever more alternative fuels and electric and hybrid engine designs are emerging to replace the dirty maritime fuels used by most heavy-duty shippers.

“Shipping, most of which is freight, has largely escaped serious decarbonization measures until now,” says Carlos Calvo Ambel of the Brussels-based watchdog group Transport & Environment. “It has to set tough, binding targets.”

A second step that governments can take is to cut back global trade in favor of more regional production. Here, too, there is movement in Europe. French President Emmanuel Macron and German Chancellor Angela Merkel recently underscored the importance of diversifying supply chains to reduce dependence on foreign production and reinforce Europe’s “economic and industrial resilience and sovereignty.” As Björn Finke, E.U. correspondent for the German daily Süddeutsche Zeitung, wrote in May, the realization that so much of Europe’s medical supplies and technology come from China has prompted politicians to rethink the continent’s trade policy: “less globalization, less division of labor between countries, more at home.”

Another policy measure that could impact imports is a recently proposed E.U. carbon border adjustment levy, which beginning by 2023 would apply a charge on goods imported into the E.U. based on the emissions emitted during their production. The tax could force trade partners to enforce emissions reduction measures not just on traded goods but on freight carriers too.

Of course, another means to decarbonize global trade would be to impose a hefty carbon tax on all international freight, as well as on aviation fuels, which currently go completely untaxed in the E.U. The E.U. is planning to apply carbon pricing to the shipping industry and reduce free carbon emission allowances currently allotted to airlines under Europe’s current policy.

These measures, though, must be implemented in a way that produces real change. Experts anticipate that trade by freight will triple by 2050, which would seriously undermine the goals of the Paris Agreement at present emissions levels. With talk of “Green Deals” in the air in Europe and the U.S., now is the time to set the freight sector on the road to comprehensive decarbonization.

Tracking 3 Decades of Dramatic Glacial Lake Growth

In the largest-ever study of glacial lakes, researchers using 30 years of NASA satellite data have found that the volume of these lakes worldwide has increased by about 50% since 1990 as glaciers melt and retreat due to climate change.

The findings, published in the journal Nature Climate Change, will aid researchers assessing the potential hazards to communities downstream of these often unstable lakes and help improve the accuracy of sea-level rise estimates by advancing our understanding of how glacial meltwater is transported to the oceans.

Glaciers are retreating on a near-global scale and this study provides scientists with a clearer picture of how much of this water has been stored in lakes.

“We have known that not all meltwater is making it into the oceans immediately,” said lead author Dan Shugar of the University of Calgary in Canada. “But until now there were no data to estimate how much was being stored in lakes or groundwater.” The study estimates current glacial lake volumes total about 37.4 cubic miles (156 cubic kilometers) of water, the equivalent of about one-third the volume of Lake Erie.

Shugar and his collaborators from governments and universities in Canada, the United States, and the United Kingdom, working under a grant from NASA’s High Mountain Asia Program, initially planned to use satellite imaging and other remote-sensing data to study two dozen glacial lakes in High Mountain Asia, the geographic region that includes the Tibetan Plateau and surrounding mountain ranges, including the Himalaya.

“We wrote scripts in Google Earth Engine, an online platform for very large analyses of geospatial data, to look only at High Mountain Asia, and then decided to look at all glacial lakes in the world,” Shugar said. “From there, we were able to build a scaling relationship to estimate the volume of the world’s glacial lakes based on the area of this large population of lakes.”

The team ultimately analyzed more than 250,000 scenes from the Landsat satellite missions, a joint NASA/U.S. Geological Survey program. A decade ago it would not have been possible to process and analyze this volume of data. The team looked at the data in five time-steps beginning with 1990 to examine all the glaciated regions of the world except Antarctica and analyze how glacial lakes changed over that period.

Shugar points out that while water from melting glaciers stored in glacial lakes is a relatively small contributor to overall sea level rise, it can have a major impact on mountain communities downstream of these glacial lakes.

Glacial lakes are not stable like the lakes in which most people are used to swimming or boating because they are often dammed by ice or glacial sediment called a moraine, which is composed of loose rock and debris that is pushed to the front and sides of glaciers. Rather, they can be quite unstable and can burst their banks or dams, causing massive floods downstream. These kinds of floods from glacial lakes, known as glacial lake outburst floods, have been responsible for thousands of deaths over the past century, as well as the destruction of villages, infrastructure, and livestock. A glacial lake outburst flood affected the Hunza Valley in Pakistan in May 2020.

“This is an issue for many parts of the world where people live downstream from these hazardous lakes, mostly in the Andes and in places like Bhutan and Nepal, where these floods can be devastating,” Shugar said. “Fortunately, organizations like the United Nations are facilitating a lot of monitoring and some mitigation work where they’re lowering the lakes to try and decrease the risks.”

In North America, the risks posed by a glacial lake outburst flood are lower.

“We don’t have much in the way of infrastructure or communities that are downstream,” Shugar said. “But we’re not immune to it.”

Arctic heating races ahead of worst-case estimates

Arctic heating is happening far faster than anybody had anticipated. And the ice record suggests this has happened before.

LONDON, 2 September, 2020 – An international team of scientists brings bad news about Arctic heating: the polar ocean is warming not only faster than anybody predicted, it is getting hotter at a rate faster than even the worst case climate scenario predictions have so far foreseen.

Such dramatic rises in Arctic temperatures have been recorded before, but only during the last Ice Age. Evidence from the Greenland ice cores suggests that temperatures rose by 10°C or even 12°C, over a period of between 40 years and a century, between 120,000 years and 11,000 years ago.

“We have been clearly underestimating the rate of temperature increases in the atmosphere nearest to the sea level, which has ultimately caused sea ice to disappear faster than we had anticipated,” said Jens Hesselbjerg Christensen, a physicist at the University of Copenhagen in Denmark, one of 16 scientists who report in the journal Nature Climate Change on a new analysis of 40 years of data from the Arctic region.

They found that, on average, the Arctic has been warming at the rate of 1°C per decade for the last four decades. Around Norway’s Svalbard archipelago, temperatures rose even faster, at 1.5°C every 10 years.

We have been clearly underestimating the rate of temperature increases in the atmosphere nearest to the sea level, which has ultimately caused sea ice to disappear faster than we had anticipated.”

During the last two centuries, as atmospheric levels of carbon dioxide climbed from an average of around 285 parts per million to more than 400ppm, so the global average temperature of the planet rose: by a fraction more than 1°C.

The latest study is a reminder that temperatures in the Arctic are rising far faster than that. And the news is hardly a shock: within the past few weeks, separate teams of researchers, reporting to other journals, have warned that Greenland – the biggest single reservoir of ice in the northern hemisphere – is melting faster than ever; more alarmingly, its icecap is losing mass at a rate that suggests the loss could become irreversible.

Researchers have also confirmed that the average planetary temperature  continues to rise inexorably, that the Arctic Ocean could be free of ice in  summer as early as 2035, and that the climate scientists’ “worst case” scenarios are no longer to be regarded as a warning of what could happen: the evidence is that what is happening now already matches the climate forecaster’s worst case. The latest finding implicitly and explicitly supports this flurry of ominous observation.

“We have looked at the climate models analysed and assessed by the UN Climate Panel,” said Professor Christensen. “Only those models based on the worst case scenario, with the highest carbon dioxide emissions, come close to what our temperature measurements show over the past 40 years, from 1979 to today.” – Climate News Network
