First evidence of human-caused climate change melting the West Antarctic Ice Sheet

A new study published this week reveals the first evidence of a direct link between human-induced global warming and melting of the West Antarctic Ice Sheet.  UK-US researchers say that curbing greenhouse gas emissions now could reduce the future sea-level contribution from this region.

Ice loss in West Antarctica has increased substantially in the last few decades and is ongoing.  Scientists have known for some time that ice loss in this region is caused by ocean-driven melt, and that varying winds in the region cause transitions between relatively warm and cool ocean conditions around key glaciers.  However, until now it was not clear how these naturally-occurring variations in the winds could cause ongoing ice loss. 

Publishing this week in the journal Nature Geoscience a UK-US science team report that, in addition to the natural variations, which last about a decade, there has been a longer-term change in the winds that can be linked with human activities.  This is an important result because continued ice loss could cause tens of centimetres of sea-level rise by the year 2100.

The research team combined satellite observations and climate model simulations to understand how winds over the ocean near West Antarctica have changed since the 1920s in response to rising greenhouse gas concentrations.  Their investigation reveals that human-induced climate change has caused a long-term change in the winds, and that warm ocean conditions have gradually become more prevalent as a result.

Lead author, Professor Paul Holland from the British Antarctic Survey (BAS), says:

“The impact of human-induced climate change on the West Antarctic Ice Sheet is not simple.  This is the first evidence for a direct link between human activities and the loss of ice from West Antarctica.

Our results imply that a combination of human activity and natural climate variations have caused ice loss in this region, accounting for around 4.5 cm of sea-level rise per century.”

The team also looked at model simulations of future winds. Prof Holland continues:

“An important finding is that if high greenhouse-gas emissions continue in future, the winds keep changing and there could be a further increase in ice melting.  However, if emissions of greenhouse gases are curtailed, there is little change in the winds from present-day conditions.  This shows that curbing greenhouse gas emissions now could reduce the future sea-level contribution from this region.”

Co-author, Professor Pierre Dutrieux from Lamont-Doherty Earth Observatory, Columbia University Earth Institute in New York, says:

“We knew this region was affected by natural climate cycles lasting about a decade, but these didn’t necessarily explain the ice loss.  Now we have evidence that a century-long change underlies these cycles, and that it is caused by human activities.”

Co-author, Professor Eric Steig from the University of Washington, says:

“These results solve a long-standing puzzle.  We have known for some time that varying winds near the West Antarctic Ice Sheet have contributed to the ice loss, but it has not been clear why the ice sheet is changing now.  Our work with ice cores drilled in the Antarctic Ice Sheet have shown, for example, that wind conditions have been similar in the past.  But the ice core data also suggest a subtle long-term trend in the winds.  This new work corroborates that evidence and, furthermore, explains why that trend has occurred.”

Air BP expands its carbon offset program for business aviation

  • Announces new collaboration with Voa São Paulo and expands carbon offsetting program to two airports in the consortium
  • 1,000 tons of carbon emissions were offset in 2018-2019 through Air BP’s carbon offsetting programme with Avantto
  • Air BP’s airfield automation digital technology for misfuelling prevention to be launched in Brazil

Air BP, the international aviation fuel products and services supplier, will highlight the expansion of its pioneering carbon offset program for business aviation in Brazil during the largest business aviation conference and exhibition in Latin America, LABACE from August 13 to 15.

The program will be extended to two of Voa São Paulo’s airports, a Brazilian private airport administration consortium, which are now part of Air BP’s supply network. Jundiaí and Amarais airports are the first to join the program and there is the potential to expand the offer to more of Voa São Paulo’s locations in the future.

“We are very proud of this new collaboration with Voa São Paulo. Our carbon offset program, which complements our existing focus on customer service and safety in operations, is a significant step towards making Brazilian business aviation more sustainable,” said Ricardo Paganini, general manager, Air BP South America.

Air BP launched its carbon offsetting offer for business aviation in Brazil in 2018. Its first customer, business aircraft management company Avantto, offset more than 1,000 tons of carbon emissions from June 2018 to May 2019 – the equivalent of 1,588 trips from São Paulo (SP / HBR) to Angra dos Reis (RJ) or the carbon that could be captured by almost 73,000 adult trees*. The agreement with Avantto has been renewed for another year, enabling customers to offset the emissions related to the fuel supplied to the company by Air BP.

This builds on initiatives by Air BP in other regions, such as their collaboration with leading on-demand jet charter marketplace Victor in a carbon-offset programme for private flying in Europe, as well as the ability for operators and pilots who use the RocketRoute MarketPlace app to offset the carbon associated with their fuel purchases.

The Air BP carbon offset programme is run via BP Target Neutral. Projects within the BP Target Neutral portfolio have been assessed on the basis of their contribution to reducing carbon emissions and their potential to support the UN’s sustainable development goals. They have been selected for their suitability in improving livelihoods for the communities they are located in, or through various educational, economic and social benefits.

A new project in the North of Brazil recently became part of the BP Target Neutral portfolio.  Kamiranga is a ceramic factory producing bricks located in the Municipality of São Miguel do Guamá (PA). In the past, the factory used native Amazon firewood as fuel to produce its ceramic pieces. In 2007, the factory switched to fuelling its kilns using exclusively renewable fuels, such as açaí seeds and sawdust. The switch to renewable fuels created significant reductions in atmospheric greenhouse gas (GHG) emissions, and enabled Kamiranga to participate in the international carbon market.

Since the first credits were issued, the project has reduced carbon emissions by more than 350,000 tons. Income generated from the sale of carbon credits is re-invested in the modernising of the factory, benefitting workers and the local community. Air BP’s carbon offset program for business aviation is part of BP’s commitment to achieving a lower carbon future, addressing the dual challenge of meeting the increasing energy the world demands, while at the same time working to reduce greenhouse gas emissions. It complements Air BP’s own carbon neutral plane fuelling operations at 250 locations around the world.

Airfield automation

Air BP is also pleased to announce at LABACE the launch of its airfield automation technology in Brazil. This new platform is designed to enhance safety, reliability and compliance in airport fuelling operations. A digital platform for operators and airports, airfield automation is an integrated, real-time, global solution that strengthens safety barriers and mitigates risks during the fuelling process.

Aside from the enhanced safety barriers, aircraft operators will also benefit from faster, more comprehensive and more accurate fuelling and delivery data. The cloud-based technology will enable Air BP to offer increasingly integrated information to customers, such as delivery records and precise delivery timings.

BP will be at Stand 3003 at LABACE.

Signature Flight Support, the world’s largest network of Fixed Base Operators (FBOs), has announced a major expansion of its European business aviation support services in Italy with the addition of 6 airports to its current in-country presence, which now totals 9 aircraft handling stations.

Signature’s expansion follows several months of preparation, including the establishment of qualified local partnerships and an exhaustive vetting process conducted by Italian aviation authorities. Existing locations at Milan-Linate (LIN), Milan-Malpensa (MXP), and Rome-Ciampino (CIA) are augmented by the addition of key airports at Bergamo (BGY), Catania (CTA), Florence (FLR), Naples (NAP), Palermo (PMO), and Pisa (PSA). Operating permits, slot acquisition, and PPR approvals are added to the portfolio of handling services coordinated from Signature’s 24/7 Italian operations center at Milan-Linate airport.

The resultant ENAC certification at Bergamo’s Orio al Serio Int’l Airport, complimented by the inauguration of a new General Aviation Terminal at Milan’s Malpensa Airport, allow for the continuation of business aviation arrivals to Northern Italy during Milan-Linate’s three month closure for runway construction.

“Signature has identified Italy as a key strategic market for business aircraft operations in Europe,” explained John-Angus Smith, Managing Director EMEA. “By adapting our business model to conform to local conditions, including our joint venture with SEA Prime and our latest handler arrangements at several Italian airports, we have developed a comprehensive support network for business aircraft operators visiting major airports throughout the country.”
