The process of recovery from the coronavirus pandemic offers the chance to change course, and put humanity on a path on which it is not in conflict with nature, the United Nations Secretary-General said on Monday, urging greater efforts by everyone to protect biodiversity and step up climate action.
Addressing world leaders at the One Planet Summit, Secretary-General António Guterres outlined the consequences of abusing Earth and its resources.
“We have been poisoning air, land and water – and filling oceans with plastics. Now, nature is striking back: temperatures are reaching record highs, biodiversity is collapsing, deserts are spreading, [and] fires, floods and hurricanes are more frequent and extreme,” he said.
“We are extremely fragile”, Mr. Guterres warned.
Combined with the devastating effects of COVID-19 and its socio-economic fallout, the UN chief reminded everyone that “as we rebuild, we cannot revert to the old normal.”
“Pandemic recovery is our chance to change course. With smart policies and the right investments, we can chart a path that brings health to all, revives economies and builds resilience and rescues biodiversity”, he highlighted.
‘Everyone must do much more’
The Secretary-General noted that innovations and nature-based solutions are especially promising, and that preserving biodiversity also creates jobs. According to the World Economic Forum, emerging business opportunities across nature could create 191 million jobs by 2030, he added.
At the same time, with a financing gap of $711 billion per year until 2030 to meet global biodiversity targets, increased and sustained financing will be crucial to transition away from polluting sectors, Mr. Guterres said.
“The time has come to…align public and private financial flows with the Paris Agreement commitments and the Sustainable Development Goals (SDGs) and integrate the goal of carbon neutrality into all economic and fiscal decisions.”
The UN chief also urged support for the most vulnerable, who are already suffering the effects of climate change, such as the least developed countries and small island developing States.
‘The sign of hope’
“Everyone must do much more … We begin a new year under the sign of hope. Together, let us seize the opportunity to build a safer, fairer and more sustainable world,” he added.
Organized by the French Government in partnership with the United Nations and the World Bank, the One Planet Summit brought together world leaders to commit action to protect and restore bio-diversity. Due to the coronavirus outbreak, the event was largely virtual.
Opening the Summit, French President Emmanuel Macron, declared that protecting and restoring biodiversity is “in our interest”.
Alongside creating millions of jobs between now and 2030, the natural world offers many benefits, he said, adding that intact forests and ocean ecosystems can help meet climate targets by acting as carbon sinks.
‘Nature offers solutions’
“Nature offers solutions for developing sustainable agriculture, for economic and financial services, helping us to preserve our heritages and cultures”, said the French President.
Mr. Macron outlined four key priorities for action: protecting terrestrial and maritime ecosystems, to allow nature to regenerate; promoting agro ecology to safeguard environment, strengthen food-security and reduce inequalities; mobilizing public and private financing, which would support both climate action and protect biodiversity; and reducing deforestation, especially tropical forests, to protect species and human health.
African greening initiative receives $14 billion
Also on Monday, the Great Green Wall for the Sahel and Sahara, an initiative to combat desertification in the vast region, received a pledge of more than $14.2 billion in new funding over the next 10 years, to restore degrading land, protect biodiversity and strengthen resilience.
According to the UN Convention on Combating Desertification Secretariat (UNCCD), overall, about $33 billion needed by the initiative to achieve its ambitious targets to restore 100 million hectares of degraded land, the soil capture of around 250 million tons of atmospheric carbon, and creation of some 10 million green jobs for communities, by 2030.
Mohamed Cheikh El-Ghazouani, President of Mauritania and the Chair of Conference of Heads of State and Government of the Pan African Agency for the Green Great Wall, welcomed the announcement.
“The mobilization of this additional funding through an innovative approach will certainly contribute to the achievement of the Great Green Wall goals”, he said.
Since its inception in 2007, the country-led Great Green Wall programme has planted billions of trees and supported tens of thousands of local households. Its path snakes along the southern margin of Africa’s Sahara Desert running from the Atlantic coast to the Red Sea.
2020, one of three warmest years on record
The COVID-19 pandemic was not the only long-term crisis the world will remember from 2020. In terms of climate change, the year was also one of the three warmest on record, and rivalled 2016 for the top spot, the UN weather agency said on Wednesday.
“The confirmation by the World Meteorological Organization (WMO) that 2020 was one of the warmest years on record is yet another stark reminder of the relentless pace of climate change, which is destroying lives and livelihoods across our planet”, said Secretary-General António Guterres.
He pointed out that at 1.2 degrees of warming above pre-industrial levels, the world is already witnessing unprecedented weather extremes in every region and on every continent.
“We are headed for a catastrophic temperature rise of 3 to 5 degrees Celsius this century”, he warned. “Making peace with nature is the defining task of the 21st century. It must be the top priority for everyone, everywhere.”
La Niña, which began in late last year, is expected to continue into the early-middle part of 2021.
“The exceptional heat of 2020 is despite a La Niña event, which has a temporary cooling effect”, said WMO Secretary-General Prof. Petteri Taalas.
La Niña and El Niño effects on average global temperatures are typically strongest in the second year of the event.
“It is remarkable that temperatures in 2020 were virtually on a par with 2016, when we saw one of the strongest El Niño warming events on record”, he added. “This is a clear indication that the global signal from human-induced climate change is now as powerful as the force of nature”.
The extent to which the continued cooling effects of La Niña this year may temporarily diminish the overall long-term warming trend remains to be seen.
Following atypical patterns
WMO pointed to sustained heat and wildfires in Siberia, diminishing Arctic sea ice and record-breaking hurricanes in the Atlantic as being among the climate events that most stood out in 2020.
The UN weather agency also reminded that temperature is just one climate change indicator. Greenhouse gas concentrations, ocean heat content, global mean sea level, sea ice extent and extreme events are also factors.
Backed by science
WMO’s consolidated global temperature update incorporates information from five leading international sets of data.
It also uses datasets that combine millions of meteorological and marine observations, including from satellites, with models to produce a complete reanalysis of the atmosphere.
“The combination of observations with models makes it possible to estimate temperatures at any time and in any place across the globe, even in data-sparse areas such as the polar regions”, according to WMO.
Looking to the future
The Paris Agreement aims to limit global warming to well below 2°C, preferably to 1.5°C degrees, compared to pre-industrial levels.
However, the global average temperature in 2020 had already approached the lower limit of the temperature increase that the Agreement seeks to avert.
Moreover, there is at least a one-in-five chance that the average global temperature will temporarily exceed 1.5 °C by 2024, according to WMO’s Global Annual to Decadal Climate Update, led by the United Kingdom’s Met Office.
The 2021 Met Office annual global temperature forecast also suggests that next year will again be one of the earth’s hottest years.
Updating its provisional December report, WMO will issue its final publication in March, which will incorporate temperature figures, information on all leading climate indicators and selected climate impacts.
Step up action and adapt to ‘new climate reality’-Report
Though countries have made progress in planning for climate change adaptation, there are significant financing shortfalls in getting them to the stage where they provide real protection against droughts, floods and rising sea levels, a new UN environment report has found.
According to the 2020 Adaptation Gap Report, released on Thursday by the UN Environment Programme (UNEP), as temperatures rise and climate change impacts intensify, nations must urgently step up action to adapt to the new climate reality or face serious costs, damages and losses.
“The hard truth is that climate change is upon us,” Inger Andersen, UNEP Executive Director, said in a news release announcing the findings.
“Its impacts will intensify and hit vulnerable countries and communities the hardest, even if we meet the Paris Agreement goals of holding global warming this century to well below 2 degrees Celsius and pursuing 1.5 degree Celsius.”
Global commitment needed
Annual adaptation costs in developing countries are estimated at $70 billion, but the figure could reach up to $300 billion in 2030, and $500 billion in 2050. Almost three-quarters of nations have some adaptation plans in place, but financing and implementation fall “far short” of what is needed, according to the UNEP report.
Stepping up public and private finance for adaptation is, therefore, urgently needed.
“As the Secretary-General has said, we need a global commitment to put half of all global climate finance towards adaptation in the next year … this will allow a huge step up in adaptation, in everything from early warning systems to resilient water resources to nature-based solutions,” Ms. Andersen added.
Adaptation is a key pillar of the Paris Agreement on Climate Change. It aims to reduce countries’ and communities’ vulnerability to climate change by increasing their ability to absorb impacts.
The UNEP report also underscored the importance of nature-based solutions as low-cost options that reduce climate risks, restore and protect biodiversity, and bring benefits for communities and economies.
Its analysis of four major climate and development funds: the Global Environment Facility (GEF), the Green Climate Fund (GCF), the Adaptation Fund, and the International Climate Initiative (IKI), suggested that support for green initiatives with some element of nature-based solutions has risen over the last two decades.
Cumulative investment for climate change mitigation and adaptation projects under the four funds stands at $94 billion. However, only $12 billion was spent on nature-based solutions, a tiny fraction of total adaptation and conservation finance, it added.
Cutting emissions will reduce costs
Cutting greenhouse gas emissions will reduce the impacts and costs associated with climate change, according to the report. Achieving the 2 degrees Celsius target of the Paris Agreement could limit losses in annual growth to up to 1.6 per cent, compared to 2.2 per cent for the 3 degrees Celsius trajectory.
UNEP urged all nations to pursue the efforts outlined in its December 2020 Emissions Gap Report, which called for a green pandemic recovery and updated Nationally Determined Contributions (NDCs) that include new net-zero commitments.
“However, the world must also plan for, finance and implement climate change adaptation to support those nations least responsible for climate change but most at risk,” the UN agency added.
“While the COVID-19 pandemic is expected to hit the ability of countries to adapt to climate change, investing in adaptation is a sound economic decision,” it said.
The plan to map every coral reef on Earth – from space
In October 2020, Australian scientists found a detached coral reef skyscraper on Australia’s Great Barrier Reef—nearly 500 meters tall and 1.5 kilometres wide— that exceeds the height of the Eiffel Tower and New York’s Empire State Building. This was the first discovery of its kind in 120 years.
It also signals a challenge – that we know relatively little about what lies underwater, given the high costs and still-nascent technology of ocean exploration.
To better understand the mysteries of the world’s oceans, a team of scientists is using satellite imaging to map out, in unprecedented detail, one of the planet’s most iconic underwater ecosystems: the shallow coral reef.
The researchers are part of the Allen Coral Atlas project, which is led by Vulcan, a philanthropic organization created by late Microsoft co-founder Paul Allen. The United Nations Environment Programme (UNEP) is working with Vulcan to build capacities of coral reef practitioners, managers and policy-makers around the world, especially in developing countries, on how to use the new Atlas.
“The atlas is meant to improve our understanding of our coral reef systems and drive better evidence-based policies to protect corals,” says Chuck Cooper, Managing Director of Government and Community Relations at Vulcan.
Corals under threat
Coral reefs foster one-quarter of all marine species and provide food, livelihoods, security and recreation for at least a billion people. But, pollution, overfishing and heatwaves due to climate change are threatening their existence.
Most coral reefs are still unmapped. Scientists are aiming to monitor, in real-time, these biodiverse underwater worlds to protect and restore them. Further, they want to identify patches of coral that are naturally more resistant to climate change. These “refugia” may hold secrets to learning how to mitigate the impact of warming seas on coral reefs.
The atlas, available to the public, uses satellite technology to create high-resolution images of corals that are then processed into detailed maps. The maps capture features that will allow scientists and the conservation community to compare coral reef health over time and understand the pressures reefs are facing.
The atlas will provide baselines for monitoring coral reef bleaching events and other short-term changes, evidence to inform policymaking, and compelling science to capture the public’s interest on the plight of corals.
Bleaching occurs when coral—tiny animals that secrete calcium carbonate for protection—become stressed by factors such as warm water or pollution. As a result, they expel the microscopic symbiotic algae called zooxanthellae, which reside within their tissues. The corals then turn ghostly white; they become ‘bleached’(watch these coral bleaching explainer videos).
The origins of the atlas
Three years ago, Paul Allen charged Vulcan with saving the world’s corals, says Paulina Gerstner, the Allen Coral Atlas Program Manager. “As a technologist, he saw tremendous data gaps and challenged us to figure out how to apply the emerging availability of satellite imagery to map and monitor the world’s coral reefs. All of them.”
Allen – an avid scuba diver – was deeply committed to the protection of marine ecosystems. He was already funding coral research, but his concern intensified in 2017 when Allen found his favourite reef dive sites bleached and dying. That’s when he tasked the team with the ambitious goal of mapping the world’s corals. (Allen died in 2018.)
“Our goal is to make conservation restoration and protection much easier, affordable and faster for all conservationists around the world,” says Gerstner.
“In the face of inaction, coral reefs will soon disappear,” says Leticia Carvalho, the Coordinator of UNEP’s Marine and Freshwater Branch. “Humanity must act with evidence-based urgency towards effective ecosystem management and protection to change the trajectory.”
UNEP is training officials in coastal states on how to use the atlas and supporting efforts to develop policies that safeguard coral reefs. Alongside Vulcan, which is funding the project, other partners include the University of Queensland, Planet Inc., Arizona State University and the National Geographic Society.
An instrumental tool
In May 2020, a long-standing partner of UNEP, the International Coral Reef Initiative (ICRI), called on its 44 member states, which are home to 75 percent of the world’s coral reefs, to step up their conservation efforts. Francis Staub, the ICRI Secretariat Coordinator, says the atlas will be instrumental in that process, helping countries understand “where coral reefs are and the area they cover.”
The atlas uses images from Planet Labs, which operates the world’s largest fleet of Earth-observing satellites. Daily, the Planet Labs’ satellites photograph Earth’s entire surface in minute detail. Researchers will analyze the satellite images and produce maps that catalogue the depths of reefs and their location, while differentiating them from other underwater phenomena, including seagrasses, rocks and sand.
The atlas coincides with the launch of two major environmental campaigns: the United Nations Decade of Ocean Science for Sustainable Development and the United Nations Decade on Ecosystem Restoration.
Notable coral reefs that have been mapped include the Great Barrier Reef in Australia, and systems in Fiji, the Bahamas and Hawaii. The project aims to have 100 per cent of the world’s reefs mapped by the summer of 2021.
