The year 2016 made history, with a record global temperature, exceptionally low sea ice, and unabated sea level rise and ocean heat, according to the World Meteorological Organization (WMO). Extreme weather and climate conditions have continued into 2017.

WMO issued its annual statement on the State of the Global Climate ahead of World Meteorological Day on 23 March. It is based on multiple international datasets maintained independently by global climate analysis centres and information submitted by dozens of WMO Members National Meteorological and Hydrological Services and Research Institutes and is an authoritative source of reference. Because the social and economic impacts of climate change have become so important, WMO partnered with other United Nations organizations for the first time this year to include information on these impacts.

“This report confirms that the year 2016 was the warmest on record – a remarkable 1.1 °C above the pre-industrial period, which is 0.06 °C above the previous record set in 2015. This increase in global temperature is consistent with other changes occurring in the climate system,” said WMO Secretary-General Petteri Taalas.

“Globally averaged sea surface temperatures were also the warmest on record, global sea levels continued to rise, and Arctic sea-ice extent was well below average for most of the year,” he said.

“With levels of carbon dioxide in the atmosphere consistently breaking new records, the influence of human activities on the climate system has become more and more evident,” said Mr Taalas.

The increased power of computing tools and the availability of long term climate data have made it possible today, through attribution studies, to demonstrate clearly the existence of links between man-made climate change and many cases of high impact extreme events in particular heatwaves, he said

Each of the 16 years since 2001 has been at least 0.4 °C above the long-term average for the 1961-1990 base period, used by WMO as a reference for climate change monitoring. Global temperatures continue to be consistent with a warming trend of 0.1 °C to 0.2 °C per decade, according to the WMO report.

The powerful 2015/2016 El Niño event boosted warming in 2016, on top of  long-term climate change caused by greenhouse gas emissions. Temperatures in strong El Niño years, such as 1973, 1983 and 1998, are typically 0.1 °C to 0.2 °C warmer than background levels, and 2016’s temperatures are consistent with that pattern.

Global sea levels rose very strongly during the El Niño event, with the early 2016 values reaching new record highs.  Global sea ice extent dropped more than 4 million square kilometres below average in November, an unprecedented anomaly for that month.

The very warm ocean temperatures contributed to significant coral bleaching and mortality was reported in many tropical waters, with important impacts on marine food chains, ecosystems and fisheries.

Carbon dioxide levels in the atmosphere reached the symbolic benchmark of 400 parts per millions in 2015 – the latest year for which WMO global figures are available – and will not fall below that level for many generations to come because of the long-lasting nature of CO2.

Noteworthy extreme events in 2016 included severe droughts that brought food insecurity to millions in southern and eastern Africa and Central America. Hurricane Matthew caused widespread suffering in Haiti as the first category 4 storm to make landfall since 1963, and inflicted significant economic losses in the United States of America, while heavy rains and floods affected eastern and southern Asia.

WMO has issued annual climate reports for more than 20 years and submits them  to the Conference of the Parties of the Framework Convention on Climate Change. The annual statements complement the assessments reports that the Intergovernmental Panel on Climate Change (IPCC) produces every six to seven years.

It will be presented to UN member states and climate experts at a high-level action event on Climate Change and the Sustainable Development Agenda  in New York on 23 March (World Meteorological Day) hosted by the President of the UN General Assembly Peter Thomson.

“The entry into force of the Paris Agreement under the UN Framework Convention on Climate Change (UNFCCC) on 4 November 2016 represents a historic landmark. It is vital that its implementation becomes a reality and that the Agreement guides the global community in addressing climate change by curbing greenhouse gases, fostering climate resilience and mainstreaming climate adaptation into national development policies,” said Mr Taalas.

“Continued investment in climate research and observations is vital if our scientific knowledge is to keep pace with the rapid rate of climate change,” said Mr Taalas.

Increasing temperatures, rising sea levels and ocean acidification amplify extremes of climate change. Finding a solution to minimise the impact on coastal areas has become a priority. That’s why COP22 host nation Morocco has set up three complementary initiatives, including the Blue Belt, devoted to issues related to fisheries

The Blue Belt initiative stemmed from the Blue Growth concept, launched by the UN’s Food and Agriculture Organisation in 2013.

It aims to encourage sustainable fishing, from seas and lakes to consumers’ plates, to allow marine resources to renew themselves.

Better fishing practices lead to less food waste

“Morocco’s vessel monitoring system (VMS), available on all Moroccan boats, is a good management tool,” Abdelkrim Foutat, President, Moroccan Association of Shipowners told Euronews. “We can follow their units, knowing exactly the distance their ship, its exact location, the time it leaves port and when it returns.”

The Blue Belt initiative aims to better observe the Atlantic Ocean and Mediterranean Sea. The marine navigation buoy is one of the tools used by the National Institute of Fisheries Research off the south coast of Morocco.

“Our ambition is to enhance, improve and implement a coastal marine observation system,” Abdelmalek Faraj, General Director, Moroccan National Institute of Fisheries Research (INRH), told Euronews. “In Morocco we began by installing an oceanographic and meteorological buoy off Dakhla. We aim to install a network in the northwest African region with our partner countries.”

Cultivating a sustainable aquaculture to limit overfishing

“Our goal is to develop and strengthen aquaculture,” said Faraj. “It has a very significant potential, the fisheries sector’s fastest growth in recent years. However, our goal is sustainable development. So we want to encourage the development of seaweed farming and that’s why in Morocco we have several experimental projects you can see here today such as with macro algae.”

The seas and oceans cover two thirds of our planet. Its environment is perhaps fragile but it’s rich in unexploited opportunities.

A Proud Partnership- Mission Blue Applauds IUCN’s Motion to Protect 30% of  the Ocean By 2030!

“Planet at the Crossroads” was the theme at this year’s World Conservation Congress. Organized by the International Union for the Conservation of Nature (IUCN), leaders took bold steps in confirming recommendations for 30% marine protection by 2030. Over 180 countries and 700 conservation groups were represented. 

Motion 53 came one week following President Obama’s historical expansion of Papahānaumokuākea Marine National Monument. Countries are now being urged to designate this as a minimum for Marine Protected Areas (MPAs). Building fuller sustainability would include the reduction of at least 30% “extractive” activities including fishing, mining, and drilling. 

Pew Charitable Trusts outlines some of the ways in which this might be accomplished: 

- States committing to designate at least 30 percent of their national waters as MPAs by 2030; 
- States engaging constructively in establishing MPAs in areas beyond national jurisdiction, through the development of a new global instrument under the United Nations Convention on the Law of the Sea and through the adoption of new and existing proposals at the Commission for the Conservation of Antarctic Marine Living Resources; and 
- IUCN State Members calling on the CBD Secretariat to initiate the process for achieving a post-Aichi target of 30 percent of coastal and marine areas fully protected by 2030.

Warming Seas

“Ocean warming may well turn out to be the greatest hidden challenge of our generation”, indicates Dan Laffoley, Marine Vice Chair of the World Commission on Protected Areas at IUCN and Mission Blue Board Member. A new IUCN report led by Laffoley illuminates the impacts of ocean warming on ecosystems and species, and on the every-day benefits derived from the ocean- it’s ‘goods and services’.  Protecting 30% of the ocean ensures resiliency to a changing climate. 

The new ocean protection goal marks a celebrated achievement towards a growing movement to conserve valuable marine biodiversity. Mission Blue and countless other ocean organizations advocated for the passage of this important motion. Over the past year, citizens and organizations across the planet have nominated marine environments especially deserving of protection – known as Hope Spots – for review by Mission Blue and IUCN. After rigorous scientific vetting and policy analysis, we recently announced the names of 14 new Hope Spots, which came directly from a concerned global community calling out for more ocean protection.

By allowing citizens to elect their own Hope Spots, Mission Blue and IUCN hope to meet the 30% goal of igniting broad public support for a global network of marine protected areas large enough to protect and restore the ocean’s health.

Report comparing past mass extinction events warns that hunting and killing of ocean’s largest species will disrupt ecosystems for millions of years.

Humanity is driving an unprecedented extinction of sealife unlike any in the fossil record, hunting and killing larger species in a way that will disrupt ocean ecosystems for millions of years, scientists have found.

A new analysis of the five mass extinction events millions of years ago discovered there was either no pattern to which marine species were lost, or smaller species were the ones that disappeared.

But today’s “sixth extinction” is unique in the way that the largest species, such as great white sharks, blue whales and southern bluefin tuna, are being pushed to the brink, due to humans’ tendency to fish for larger species more often than smaller ones.

The consequences, according to a study published in the journal Science on Wednesday, are devastating for the ecology of the world’s oceans.

“If this pattern goes unchecked, the future oceans would lack many of the largest species in today’s oceans,” said Jonathan Payne, associate professor and chair of geological sciences at Stanford University. “Many large species play critical roles in ecosystems and so their extinctions could lead to ecological cascades that would influence the structure and function of future ecosystems beyond the simple fact of losing those species.”

The danger is disproportionate to the percentage of threatened species, with the authors warning the loss of giants would “disrupt ecosystems for millions of years even at levels of taxonomic loss far below those of previous mass extinctions”.

The loss of larger species in the oceans could have knock-on effects on ecosystems, Payne said, citing the loss of very large predatory seasnails (Triton) from coral reefs, which appears to be one of the reasons behind the explosive growth in numbers of crown of thorns starfish, which eat coral.

Humans would be affected by such trends too, he said, as communities rely on coral reefs to attract tourism. He also pointed to the examples of tuna and cod, whose extinction would deprive people of an important source of income and protein.

To see how the current loss of species compared to previous extinctions, Payne and his team analysed a database of 2,497 groups of marine vertebrate and mollusc over the past 500 years, and compared it to the ancient past.

They found no precedent in the fossil record for today’s trend towards killing off larger-bodied species, with previous mass extinctions marked by either no association with body size or an association with smaller species.

“The link that we found between body size and extinction threat in the modern oceans is quite strong,” Payne told the Guardian.

Co-author Noel Heim, also at Stanford, said: “We see this over and over again. Humans enter into a new ecosystem, and the largest animals are killed off first. Marine systems have been spared up to now, because until relatively recently, humans were restricted to coastal areas and didn’t have the technology to fish in the deep ocean on an industrial scale.”

Fellow author Douglas McCauley said large body size was often linked with the need for larger ocean spaces to range in, so an increasing trend for governments to create very large marine protected areas could hold some hope for species.

“Historically marine protected areas have been small boutique affairs - more like the size of golf courses. In the past five years, however, the world has begun aggressively setting up very large marine protected areas.

“Recently Obama created the world’s largest protected area in Papahānaumokuākea, a protected area just over a million square kilometres in size. This is really good news as parks of this size will indeed provide meaningful protection for large vulnerable animals we highlight as being at risk.”
