“Business as usual” could lead to catastrophic global sea-level rise

MD Staff

As hurricane season bears down on many people and communities this month, one of the key factors linked to increasing severity of a storm’s impacts—sea level rise—sees new predictions emerge for “worst-case scenarios”.

Mathematicians and scientists calculate likely and possible outcomes based on probabilities, with computers able to crunch ever larger volumes of data to come up with more accurate predictions.

Climate modelling has improved enormously in the past 20 years, and where predictions of catastrophe are distinct—as opposed to remote—we should take note.

In Ice sheet contributions to future sea-level rise from structured expert judgment, published in the Proceedings of the National Academy of Sciences of the United States of America in May 2019, scientists conclude that if global temperatures reach 5°C above pre-industrial era levels, there is a one in 20 chance that global mean sea level rise could exceed two metres.

A 5°C temperature rise is consistent with unchecked emissions growth.

“This is more than twice the upper value put forward by the Intergovernmental Panel on Climate Change in the Fifth Assessment Report [2013],” notes the study.

Such a rise over the next 80 years could trigger the gradual displacement of millions of people around the world and swallow up an area of land three times the size of Texas.

Much of the land losses would be in important food-growing areas such as the Nile delta. Coastal communities, ports and low-lying countries like Bangladesh would be hard hit. Large numbers of small islands would disappear. Major global cities, including London, New York and Shanghai would end up, at least partially, underwater.

Under a “business as usual” scenario where temperatures rise by 5°C, the picture is even grimmer beyond 2100, with a projected increase by 7.5 metres.

A New Climate for Peace: Taking Action on Climate and Fragility Risks, commissioned by members of the G7 group of nations, outlines seven “climate-fragility” risks that pose serious threats to global stability in the next decades.

One of the risks identified is rising sea levels: “Rising sea levels are threats to the economic and physical viability of low-lying areas, as land and coastal resources are gradually lost. This can lead to social disruption, displacement and migration, as well as disagreements over maritime boundaries and ocean resources.”

UN Secretary-General António Guterres recently warned: “The loss of ice in Greenland and Antarctica is accelerating, meaning that sea levels will rise a full metre by 2100 if nothing is done to avoid it.”

Important warning

Through its Joint Unit with the UN Office for the Coordination of Humanitarian Affairs, UNEP at the request of governments, seconds disaster assessment experts to areas affected by climate-related emergencies. This was the case in 2017, after Hurricane Maria struck Dominica and Puerto Rico, as well as in April 2019 after cyclones Idai and Kenneth hit Mozambique.

In collaboration with United Nations Office for Project Services (UNOPS), and with funding from the Global Environment Facility, UNEP supported the Government of Tanzania to build extensive seawalls along the country’s coast, including over 2,400m of defence structures. The project, which was completed in June 2018, was part of a broader UNEP initiative to build climate resilience by improving natural ecosystems.

UNEP also works with partners to highlight scientific issues of emerging concern, for example, in its annual Frontiers Report.

The climate crisis is gaining the attention of the world’s media and politicians. Several countries have declared climate emergencies, and climate emergency declarations have reportedly been made in several hundred jurisdictions and local governments covering over 100 million citizens.  

Nineteen countries and 32 cities have joined the Carbon Neutrality Coalition, committing to take concrete and ambitious action to achieve the aims of the Paris Climate Agreement. This means they aim to be carbon neutral by 2050. The world’s largest container shipping company as well as dozens of big-name fashion brands have made similar commitments.

“With around 40 per cent of the world’s population living within 100 km of a coast, we need to do everything possible to make this scenario less likely and prevent us from reaching tipping points beyond which it will not be possible to prevent runaway climate change,” Hagelberg adds.

Over 6 million people currently live in coastal areas vulnerable to sea level rise today. Even in a 2°C global heating scenario, 10 million more would be affected, according to the Intergovernmental Panel on Climate Change. 

“Ocean science plays a crucial role in achieving sustainable development and UN-Oceans remains committed to playing its part in enhancing science to achieve this objective,” said Miguel de Serpa Soares, Under-Secretary-General for Legal Affairs and United Nations Legal Counsel, and UN-Oceans Focal Point, in a statement on 13 June 2019 in New York.

Vietnam Signs Landmark Deal with World Bank to Cut Carbon Emissions

Newsroom

Published

on

Vietnam’s Ministry of Agriculture and Rural Development signed a landmark agreement today with the World Bank’s Forest Carbon Partnership Facility (FCPF), unlocking up to US$51.5 million for Vietnam’s efforts to reduce carbon emissions from deforestation and forest degradation between now and 2025. With this Emission Reductions Payment Agreement (ERPA) in place, Vietnam is expected to reduce 10.3 million tons of carbon dioxide emissions from six North Central Region provinces of Thanh Hoa, Nghe An, Ha Tinh, Quang Binh, Quang Tri and Thua Thien Hue to receive $51.5 million from the FCPF.

Vietnam has shown tremendous leadership in developing robust programs to deliver forest emission reductions at scale,” saidCarolyn Turk, World Bank Country Director for Vietnam. “This agreement marks the beginning of a new chapter for Vietnam, where new and significant incentives for forest protection and improved management are now in place to help the country meet its ambitious climate targets.”

Vietnam’s Emission Reductions Program is designed to address the underlying causes of forest loss in the country’s North Central Region and by so doing reducing emissions from deforestation and forest degradation. The program will also support forest restoration. The region was chosen for its critical biodiversity importance and socio-economic status. The program area covers 5.1 million hectares of land (16 percent of the land area of the country), of which 3.1 million hectares are currently forested, and includes five internationally recognized conservation corridors. It is home to approximately 10.5 million people, nearly one third of whom live below the national poverty line.

“Vietnam’s program follows a preparation phase that built our readiness to engage in an emission reduction payment agreement of this kind and is a step towards full implementation of forest carbon services in Vietnam. This agreement highlights the collaboration between Vietnam, FCPF and the World Bank to meet international climate targets laid out in the Paris Agreement,” said Ha Cong Tuan, Standing Vice Minister of Agriculture and Rural Development. “Our program will mobilize important additional financing to invest in our forests and reduce forest degradation while generating income for forest owners and improving sustainable development in the North Central Region.”

Vietnam is the first country in Asia-Pacific and fifth globally to reach such a milestone agreement with the FCPF. ERPAs are innovative instruments that incentivize sustainable land management at scale and help to connect countries with other sources of climate financing. The resources from the FCPF provide new opportunities to conserve and regenerate forest landscapes and biodiversity while simultaneously supporting sustainable economic growth, which is critical for Vietnam’s development going forward.

The Forest Carbon Partnership Facility (FCPF) is a global partnership of governments, businesses, civil society, and Indigenous Peoples’ organizations focused on reducing emissions from deforestation and forest degradation, forest carbon stock conservation, the sustainable management of forests, and the enhancement of forest carbon stocks in developing countries, activities commonly referred to as REDD+. Launched in 2008, the FCPF has worked with 47 developing countries across Africa, Asia, and Latin America and the Caribbean, along with 17 donors that have made contributions and commitments totaling US$1.3 billion.

New State of Nature report points to persisting pressures on Europe’s nature

Newsroom

Published

on

European Commission published its latest assessment of the state of nature in the European Union. It provides a comprehensive overview of the situation of Europe’s most vulnerable species and habitats protected under EU nature laws

Decline of protected habitats and species still continues, caused mostly by intensive agriculture, urbanisation, unsustainable forestry activities and changes to freshwater habitats. Pollution of air, water and soil also impacts habitats, as well as climate change, over-exploitation of animals through illegal harvesting and untenable hunting and fishing. If not addressed, this decline will inevitably result in the continued erosion of our biodiversity and the vital services it provides, putting human health and prosperity at risk.

The report underlines the clear need for action if we are to have any serious chance of putting Europe’s biodiversity on a path to recovery by 2030, as envisaged in the new EU Biodiversity Strategy. In this regard, the full implementation of the goals and targets proposed in the Strategy, as well as in the Farm to Fork Strategy will be essential.

The assessment – based on a more detailed technical report of the European Environment Agency – shows that while there are protected species and habitats that are managing to hold the line despite being subject to major pressure, the majority have poor or bad status at EU level, with some showing continued deteriorating trends.

Among species, birds that are closely associated with agriculture continue to decline, while freshwater fish have the highest proportion of bad conservation status (38 %) primarily due to changes to waterbodies and water-flow and hydropower installations. Among habitats, only 15% of them are in good condition. Restoration of peatlands and other wetlands can deliver nature benefits, but also significantly contribute to addressing climate change, creating employment opportunities in rural and peripheral areas.

The report also shows that targeted conservation action brings results. The Iberian lynx, the forest reindeer and the otter, each of which has been targeted by major conservation projects, are now recovering. Initiatives under the EU LIFE programme, dedicated agri-environment schemes under the common agricultural policy, and the Natura 2000 network with its 27,000 sites continue to have a positive influence, but this needs to be scaled up considerably. 

Commissioner for the Environment, Oceans and Fisheries Virginijus Sinkevičius said: “This State of Nature assessment is the most comprehensive health check of nature ever undertaken in the EU. It shows, yet again, very clearly that we are losing our vital life support system. As much as 81 % of protected habitats are in poor condition in the EU. We urgently need to deliver on the commitments in the new EU Biodiversity Strategy to reverse this decline for the benefit of nature, people, climate and the economy.”

Hans Bruyninckx, Executive Director of the European Environment Agency, said: “Our assessment shows that safeguarding the health and resilience of Europe’s nature, and people’s well-being, requires fundamental changes to the way we produce and consume food, manage and use forests, and build cities. These efforts need to be coupled with better implementation and enforcement of conservation policies, a focus on nature restoration, as well as increasingly ambitious climate action, especially in the transport and energy sector.”

Background

Every six years, EU Member States report on the conservation status and trends of species and habitat types protected under the EU Directives. The present reporting cycle is the largest and most extensive data-gathering exercise ever undertaken on the state of Europe’s nature. The report provides an analysis of data on status and trends related to all wild bird species occurring in the EU (460 species), 233 habitat types and almost 1400 other wild plants and animals of European interest.

This knowledge will guide EU’s action on biodiversity in the coming years, providing a crucial baseline for monitoring progress towards achieving the targets of the new EU Biodiversity Strategy to 2030.

Celebrating African youth turning the tide on plastic pollution

Newsroom

Published

on

More than 400 young Africans were today honoured for their leadership in addressing plastic pollution in their communities as part of the Tide Turners Plastic Challenge. At a high-level event, political leaders, senior UN officials and Grammy-nominated Ghanaian musician Rocky Dawuni lauded the leadership shown by young people in global efforts to fight plastic pollution.

The African Youth Summit – Tide Turners Plastic Challenge acknowledged the role of more than 400 champions who have completed all three levels of the Tide Turners Plastic Challenge Badge. Participants in the Challenge have shown leadership by raising awareness through social media, championing plastic waste collection campaigns and demonstrating sustainability in their own lives, among other things.

Funded by the United Kingdom for the past two years, the Tide Turners Plastic Challenge has been completed by more than 225,000 young people in over 25 countries, including 50,000 in Africa. The challenge takes the participants on a learning journey consisting of three different levels: entry, leader, and champion.

More than 1,500 young people attended the Summit, organised by the UN Environment Programme (UNEP) in partnership with the World Association of Girl Guides and Girl Scouts, the World Organization of the Scout Movement and Junior Achievement Africa.

“As a former Girl Guide, I am very proud of Tide Turners and all the inspiring young people who are part of it; so far, more than 50,000 young people in 18 countries across Africa have joined this important programme. Let’s continue this momentum, adding seven more countries to reach youth in nearly half of all African countries,” said Joyce Msuya, Deputy Executive Director of UNEP.

The Summit which took place alongside the Scouts during their annual Jamboree on the Air and Jamboree on the Internet event (JOTA-JOTI) to share lessons from the actions young people have taken to fight plastic pollution and become environmental leaders in their communities. Six young changemakers shared their stories about how they went about provoking change and inspiring their peers to join them in taking action on plastic pollution.

“The Tide Turners Plastic Challenge gave me a great platform to pass on the message against plastic waste and share my solutions,” said Fyona Seesurrun, a 22-year old student from Mauritius, one of the champions who was honoured at the summit.

“100,000 mammals and one million birds die every year from eating or getting tangled in plastic in the ocean. If we do nothing, the amount of plastic in the ocean is set to treble by 2025. We must take collective action now. The Tide Turners are a force to be reckoned with, inspiring a whole new generation of leaders to tackle plastic pollution within their communities. That’s why the UK is supporting the UNEP to extend the work of the Tide Turners Plastic Challenge Badge to a further 20 countries around the world”, said Zac Goldsmith, UK Minister of State for Pacific and the Environment. 

Grammy-nominated Ghanaian musician Rocky Dawuni – a UNEP Goodwill Ambassador – also addressed the young people at the Summit and serenaded guests with hits including “Rock Your Soul”.

The Tide Turners Plastic Challenge Badge is the first ever Scout and Girl Guide Badge made from recycled plastic; the Challenge has been integrated into a new digital platform for World Scouting’s new environmental education initiative: Earth Tribe, which unites 54 million Scouts in a global youth movement for the environment, and offers young people the opportunity to learn and act on key environmental issues that are affecting their communities.  

In 2021, organisers will be adding a new element to the badge which will focus on influencing policy and practice change.

Each year, more than 8 million tons of plastic ends up in the oceans, wreaking havoc on marine wildlife, fisheries, and tourism, and costing at least $8 billion in damage to marine ecosystems. World production of plastic materials in 2018 was estimated at 359 million tonnes and by 2040, the amount of plastic going into our oceans could triple.
