Countries Pledge to Reverse Destruction of Nature After Missing Biodiversity Targets
By Ajit Niranjan
Leaders from across the world have promised to turn environmental degradation around and put nature on the path to recovery within a decade.
"We are in a state of planetary emergency," the 65 leaders, who include German Chancellor Angela Merkel and Bangladesh Prime Minister Sheikh Hasina, wrote ahead of a UN biodiversity summit on Wednesday. "We commit ourselves not simply to words, but to meaningful action and mutual accountability."
The commitments, which come two days before a UN biodiversity summit in New York, include eliminating plastic leakage to the oceans by 2050 and incentivizing banks and businesses to value the natural world. The leaders identify unsustainable production and consumption as a key driver of environmental crises that "require urgent and immediate global action."
But strongmen leading some of the world's biggest polluters — U.S., China, India, Russia and Brazil — are not among the signatories.
The pledge follows the September publication of a landmark assessment of biodiversity which showed humanity had failed to fully achieve any of the 20 global biodiversity targets set by the UN ten years ago. Just six of them had been "partly achieved," the report said. For one goal, on protecting coral reefs, the world was found to be moving in the opposite direction.
Data from individual governments shows that a third of national biodiversity targets, which are set by the countries themselves, are on track to be met or exceeded. But these are less ambitious than the UN targets and less than a quarter match up well with the global goals to protect nature.
The vision for biodiversity set out in 2010 is only achievable if the world responds to "compelling evidence" that "transformative change" is required, said Elizabeth Maruma Mrema, executive secretary of the UN's Convention on Biological Diversity, which prepared the Global Biodiversity Outlook (GBO) report.
Global Decline in Biodiversity
The charge sheet is long. Pollution from plastics and pesticides have not been brought down to safe levels. Governments still subsidize businesses that damage ecosystems. Coral reefs, which are dying across the world, are struck by the triple-threat of human action: climate change, pollution and overfishing. Some of those drivers are getting worse.
And even where there is progress, it is rarely enough. Deforestation should have been halted by now, but has only been cut by a third, with Asia and Europe gaining forests while Africa and South America lose them at a faster rate.
Conservation efforts have saved species like the Puerto Rican amazon parrot and the Mongolian Przewalski's horse. But they have failed to keep others like the Western Black Rhino or the Christmas Island pipistrelle from being wiped out forever.
While the big trends in biodiversity loss were already known, the UN report included "systematic analysis" on how well the world has achieved the 2010 targets, said Josef Settele, an ecologist at the Helmholtz Center for Environmental Research in Germany, who contributed research to the report but was not involved in writing it.
"There is also some brightness," Settele added. "The things we are doing are not completely in vain."
For instance, almost 100 countries have incorporated biodiversity values into national accounting systems. Over the last 20 years, the world has increased the share of protected areas from 10% to 15% on land and from 3% to 7% in water.
There are now more fish in waters managed by good fishing policies. Governments are increasingly eradicating invasive species from islands. And since 1993, conservation actions have prevented the extinction of between 28 and 48 bird and mammal species, according to a study published this month in the journal Conservation Letters — though many remain highly threatened and may still become extinct.
"The progress toward conserving life on earth has been much greater than it would have been [without action]," said Thomas Brooks, chief scientist at the International Union for Conservation of Nature, who was a co-author of the Conservation Letters study but was not involved in the GBO. "The absolutely key question is how to scale up from where things currently are, in terms of responses, to meet targets comprehensively."
Protecting Wildlife, Not Just Individual Species
The way to get that scale, according to the GBO report, is by "mainstreaming" the opportunities and responsibilities from protecting nature. That means every level of society — from individuals and local communities to businesses and national governments — would need to factor biodiversity into their economic decisions.
Like climate change, ecological collapse is happening at breakneck speed. A 2019 report by IPBES, the UN panel of biodiversity experts, found that humans are altering the natural world at an "unprecedented pace" and threatening 1 million animal and plant species with extinction.
Scientists say both issues require systemic changes, but individual actions can help. Agriculture is one of the greatest drivers of biodiversity loss and greenhouse gas emissions. A study published in the journal Nature this month found that more than two-thirds of future biodiversity losses could be avoided by conserving and restoring land, reducing food waste and switching to more plant-based diets.
They are among many actions laid out in the GBO report to reduce and eventually restore lost biodiversity.
If we do not act faster, said Inger Andersen, executive director of the UN Environment Program, "biodiversity will continue to buckle" under the weight of overexploitation, climate change, pollution, invasive alien species and changes to land and sea. "This will further damage human health, economies and societies — with particularly detrimental effects on indigenous peoples and local communities."

The speed and scale of the response to COVID-19 by governments, businesses and individuals seems to provide hope that we can react to the climate change crisis in a similarly decisive manner - but history tells us that humans do not react to slow-moving and distant threats.
A Game of Jenga<p>Think of it as a game of Jenga and the planet's climate system as the tower. For generations, we have been slowly removing blocks. But at some point, we will remove a pivotal block, such as the collapse of one of the major global ocean circulation systems, for example the Atlantic Meridional Overturning Circulation (AMOC), that will cause all or part of the global climate system to fall into a planetary emergency.</p><p>But worse still, it could cause runaway damage: Where the tipping points form a domino-like cascade, where breaching one triggers breaches of others, creating an unstoppable shift to a radically and swiftly changing climate.</p><p>One of the most concerning tipping points is mass methane release. Methane can be found in deep freeze storage within permafrost and at the bottom of the deepest oceans in the form of methane hydrates. But rising sea and air temperatures are beginning to thaw these stores of methane.</p><p>This would release a powerful greenhouse gas into the atmosphere, 30-times more potent than carbon dioxide as a global warming agent. This would drastically increase temperatures and rush us towards the breach of other tipping points.</p><p>This could include the acceleration of ice thaw on all three of the globe's large, land-based ice sheets – Greenland, West Antarctica and the Wilkes Basin in East Antarctica. The potential collapse of the West Antarctic ice sheet is seen as a key tipping point, as its loss could eventually <a href="https://science.sciencemag.org/content/324/5929/901" target="_blank">raise global sea levels by 3.3 meters</a> with important regional variations.</p><p>More than that, we would be on the irreversible path to full land-ice melt, causing sea levels to rise by up to 30 meters, roughly at the rate of two meters per century, or maybe faster. Just look at the raised beaches around the world, at the last high stand of global sea level, at the end of the Pleistocene period around 120,0000 years ago, to see the evidence of such a warm world, which was just 2°C warmer than the present day.</p>
Cutting Off Circulation<p>As well as devastating low-lying and coastal areas around the world, melting polar ice could set off another tipping point: a disablement to the AMOC.</p><p>This circulation system drives a northward flow of warm, salty water on the upper layers of the ocean from the tropics to the northeast Atlantic region, and a southward flow of cold water deep in the ocean.</p><p>The ocean conveyor belt has a major effect on the climate, seasonal cycles and temperature in western and northern Europe. It means the region is warmer than other areas of similar latitude.</p><p>But melting ice from the Greenland ice sheet could threaten the AMOC system. It would dilute the salty sea water in the north Atlantic, making the water lighter and less able or unable to sink. This would slow the engine that drives this ocean circulation.</p><p><a href="https://www.carbonbrief.org/atlantic-conveyor-belt-has-slowed-15-per-cent-since-mid-twentieth-century" target="_blank">Recent research</a> suggests the AMOC has already weakened by around 15% since the middle of the 20th century. If this continues, it could have a major impact on the climate of the northern hemisphere, but particularly Europe. It may even lead to the <a href="https://ore.exeter.ac.uk/repository/handle/10871/39731?show=full" target="_blank" rel="noopener noreferrer">cessation of arable farming</a> in the UK, for instance.</p><p>It may also reduce rainfall over the Amazon basin, impact the monsoon systems in Asia and, by bringing warm waters into the Southern Ocean, further destabilize ice in Antarctica and accelerate global sea level rise.</p>

Is it Time to Declare a Climate Emergency?<p>At what stage, and at what rise in global temperatures, will these tipping points be reached? No one is entirely sure. It may take centuries, millennia or it could be imminent.</p><p>But as COVID-19 taught us, we need to prepare for the expected. We were aware of the risk of a pandemic. We also knew that we were not sufficiently prepared. But we didn't act in a meaningful manner. Thankfully, we have been able to fast-track the production of vaccines to combat COVID-19. But there is no vaccine for climate change once we have passed these tipping points.</p><p><a href="https://www.weforum.org/reports/the-global-risks-report-2021" target="_blank">We need to act now on our climate</a>. Act like these tipping points are imminent. And stop thinking of climate change as a slow-moving, long-term threat that enables us to kick the problem down the road and let future generations deal with it. We must take immediate action to reduce global warming and fulfill our commitments to the <a href="https://www.ipcc.ch/sr15/" target="_blank" rel="noopener noreferrer">Paris Agreement</a>, and build resilience with these tipping points in mind.</p><p>We need to plan now to mitigate greenhouse gas emissions, but we also need to plan for the impacts, such as the ability to feed everyone on the planet, develop plans to manage flood risk, as well as manage the social and geopolitical impacts of human migrations that will be a consequence of fight or flight decisions.</p><p>Breaching these tipping points would be cataclysmic and potentially far more devastating than COVID-19. Some may not enjoy hearing these messages, or consider them to be in the realm of science fiction. But if it injects a sense of urgency to make us respond to climate change like we have done to the pandemic, then we must talk more about what has happened before and will happen again.</p><p>Otherwise we will continue playing Jenga with our planet. And ultimately, there will only be one loser – us.</p>
