“A healthy planet is essential for a peaceful future …Every year, more than 8 million tons of plastic end-up in the oceans.”

M. Guterres, UN Secretary-General,World Environmental Day on June 5th, 2018.

Recognized as one of the greatest universal challenges by the international community [1], this year plastic pollution has been the central focus of the Earth Day (April 22nd), the World Environmental Day (June 5th) and the International Ocean Day (June 8th), with the objectives of raising awareness on this issue and engaging communities at all levels to fight against plastic waste, especially in the oceans.

World Oceans Day 2018 – 4sea’s look back and outlook between COP23 and COP24

This article is part of the 4sea project.

When 4sea started its work about one year ago we wanted to shed light on the mysteries of the ocean. We raised awareness and understanding of the consequences of climate change on the ocean by articles, videos and workshops. In the international climate change conference we worked on the Ocean Pathway Partnership and showed why and where to give the oceans a home in UNFCCC.

Ocean Energy and Innovation: 2018 is key for the wave and tidal energy sectors development in Europe

This article is part of the 4sea project.

European leadership in ocean energies

European companies in the wave and tidal energy sectors count among the leaders in the market. In 2014, around 50% of global wave and tidal energy companies were from the European Union (EU) (European Commission, 2014). Such renewable energy sources are central to reduce electricity production emissions in the European Union, at a time when it is necessary to cut global emissions drastically if we want to follow a path of 2°C or less (2°C of global average temperature at the surface of the Earth, as mentioned in the COP21 Paris Agreement). As a consequence, innovation should be fostered by public and private support.

Engineering the oceans

 This article is part of the 4sea project.

Most of us who care about the oceans know well the threats posed by climate change – of rising seas, disappearing coral reefs and changing circulation. Less well known, however, are the threats posed by our attempts to solve the climate crisis. In our efforts to curb the problems associated with the greenhouse effect, it is very possible that we could accidentally make them worse.

The prime suspect? A proposed ‘solution’ to the climate crisis known as geoengineering – the idea to meddle with environmental processes in an attempt to slow down climate change. This term covers a range of ideas, from making ecosystems take up more carbon from the air, to artificial cooling, to collecting and storing carbon dioxide to keep it out of the atmosphere. Unsurprisingly due to the ocean’s vital role in the climate system, most of these schemes either centre on altering aspects of the marine environment, or would be likely to cause large side effects.

The New Disney’s Commitment: Ocean Protection In The Movie “Dolphins”

 This article is part of the 4sea project.

Let’s dive into the heart of the ocean to discover a mysterious world full of colors and marine species. After Disney’s African Cat, Chimpanzee it is now Dolphins which sends a message about wildlife protection. Recently released in the end of march this year, the movie was directed by Keith Scholey and Alastair Fothergill. It took them 400 days across 10 countries to make the movie – and it is absolutely worth it!

Marine biodiversity offsetting: policies, practices and challenges

 This article is part of the 4sea project.

Biodiversity loss is a major environmental challenge as providing invaluable services to society. However, ecosystems are still unknown and negative impacts related to this loss cannot be completely evaluated to plenty understand the challenge facing humankind. Therefore, to meet the objectives of biodiversity no net loss (NNL) and of economic development, biodiversity offsetting approach is being increasingly adopted yet staying a controversial tool. Indeed, methodologies and framework are still under development and its implementation remains uncertain (Bull et al, 2013). But in a world where economic growth remains the most important issue, biodiversity offsets offer an approach that enables linkage between ecological conservation with industry.

The CNRS publishes a real-life ocean bible

 This article is part of the 4sea project.

Last Tuesday, a presentation was organized by the CLORA (Club des Organismes de Recherches Associés), a Brussels based organisation in charge of representing to the European Union the French research laboratories such as : CNRS, IRD, IFREMER, etc, to present two new scientific publications on ocean issues. These two publications have one common point, they are both highlighting the richness of our oceans and the necessity to protect them.

Development of wind farms on the high seas: a new challenge for the international law of the sea

 This article is part of the 4sea project.

Climate change and growth of the world population is finally making us create a common wake-up call about to be taken serious: the use of fossil fuels must be reduced. As a result of this, development of renewable energy is gaining ground. For a long time, renewable energy has been developed land-based, however there is now a growing trend for renewable energy to be developed in the sea. Because of the benefits of offshore renewable resources, sea is becoming a playing field for new developments. For example, as for wind energy, marine winds are more abundant, stronger, and blow more consistently than land winds.

Housewarming Party – Ocean Pathway Partnership builds up a Home for Oceans within UNFCCC

 This article is part of the 4sea project

Historically, oceans were the sole connectors of the earth: from expeditions by ship to messages in bottles, the oceans provided a channel between continents. Nowadays, one may say the UN is the main channel by which states communicate, at least on a diplomatic level. Other channels, including technology, international trade and the transport sector, come with one significant downside: carbon emissions, which drive climate change. Affected ecosystems are linked such that the melting Arctic causes sea-level rise in far off Pacific islands. As youth and young ocean lovers we celebrate the Ocean Pathway Partnership today since we think: partnership should not only follow economic logics but solidarity especially when facing climate change.

La Niña and El Niño: How these crazy siblings influence the global climate system

Lima in different light

Remember when 2014 the world came together in Lima for the Conference of the Parties 20? Back then Lima was a nice city, Peru a good host. When the pictures of the extreme rain falls came in the beginning of March Lima was hardly recognisable.

Since the beginning of March rainfalls in the region of the Anden mountains are up to 10 times stronger than normally. This causes extreme floods everywhere because the rainfalls endure up to several days. Rainfalls, a landslide and mudflows led to incredible damages in the capital which was even isolated from other cities. Flooded roads, flooded auto routes, flooded houses and mudflows everywhere: Peru did not only suffer from a lot of damage but is also facing a dangerous situation. More than 100 dead persons, cities and people who needed to move away: The situation is almost as serious and strong as 1998 when about 400 people died.
