Unite behind the science and take urgent climate action
by World Meteorological Organization, agencies
 
Sep. 2020
 
The United in Science 2020 Report has been compiled by the World Meteorological Organization (WMO) under the direction of the United Nations Secretary-General brings together the latest climate science related updates from a group of key global partner organizations – WMO, Global Carbon Project (GCP), UNESCO Intergovernmental Oceanographic Commission (UNESCO-IOC), Intergovernmental Panel on Climate Change (IPCC), UN Environment Programme (UNEP) and the Met Office.
 
Antonio Guterres, Secretary-General of the United Nations:
 
'This has been an unprecedented year for people and planet. The COVID-19 pandemic has disrupted lives worldwide. At the same time, the heating of our planet and climate disruption has continued apace. Record heat, ice loss, wildfires, floods and droughts continue to worsen, affecting communities, nations and economies around the world. Furthermore, due to the amount of greenhouse gases emitted in the past century, the planet is already locked into future significant heating.
 
The solution to slowing down the rate of global temperature rise and keeping it below 1.5°C is for nations to dramatically cut emissions, with the aim of achieving carbon neutrality by 2050.
 
While emissions fell during the peak of the pandemic confinement measures, they have already mostly recovered to within 5 per cent of the same period in 2019 and are likely to increase further. This report stresses that short-term lockdowns are no substitute for the sustained climate action that is needed to enable us to meet the goals of the Paris Agreement on Climate Change.
 
Never before has it been so clear that we need long term, inclusive, clean transitions to tackle the climate crisis and achieve sustainable development. We must turn the recovery from the pandemic into a real opportunity to build a better future.
 
In order to do that, governments need consistent and solid science, backed by the strong collaboration of scientific institutions and academia, to underpin policy decisions that can tackle the greatest challenges of our time.
 
This report by the United Nations and global scientific partner organizations, provides an update one year from the first United in Science report, which was launched to inform the United Nations Climate Action Summit 2019.
 
United in Science 2020 presents a unified assessment of the state of our Earth system, detailing how emissions have evolved in 2020, and providing projections for the critical years ahead.
 
The report further addresses key thematic issues on the front lines of climate change, such as water, oceans and the cryosphere and highlights the vulnerability of land-based, marine and air observing systems which are essential to underpin our understanding of climate science.
 
We need science, solidarity and solutions to tackle both the COVID-19 pandemic and the climate crisis. I urge leaders to heed the facts contained in this report, unite behind the science and take urgent climate action to set a path towards a safer, more sustainable future for all'.
 
Petteri Taalas, Secretary-General of the World Meteorological Organization:
 
'2020 has been a remarkable year in many ways. Not least of course because of the global pandemic, impacting lives and livelihoods across the planet like never before. This year has also been remarkable in terms or our climate, continuing the trend we have seen in recent decades.
 
Greenhouse gas concentrations - which are already at their highest levels in 3 million years - have continue to rise, reaching new record highs this year.
 
Meanwhile, large swathes of Siberia have seen a prolonged and remarkable heatwave during the first half of 2020, which would have been almost impossible without anthropogenic climate change. And now 2016–2020 is set to be the warmest five year period on record. This report shows that whilst many aspects of our lives have been disrupted in 2020, climate change has continued unabated'.

Living Planet Report reveals two-thirds decline in wildlife populations since 1970
by WWF International, Zoological Society of London
 
Sep. 2020
 
WWF is calling for urgent action to end the destruction of natural habitats and reform our food system
 
Global populations of mammals, birds, amphibians, reptiles and fish have suffered an average two-thirds decline in less than half a century due in large part to the very same environmental destruction which is contributing to the emergence of zoonotic diseases such as COVID-19, according to WWF’s Living Planet Report 2020.
 
The Living Planet Index (LPI) shows that factors believed to increase the planet’s vulnerability to pandemics - including land-use change and the use and trade of wildlife - were also some of the drivers behind the 68 per cent average decline in global vertebrate species populations between 1970 and 2016.
 
“The Living Planet Report 2020 underlines how humanity’s increasing destruction of nature is having catastrophic impacts not only on wildlife populations but also on human health and all aspects of our lives,” said Marco Lambertini, Director General, WWF International.
 
“We can’t ignore the evidence – these serious declines in wildlife species populations are an indicator that nature is unravelling and that our planet is flashing red warning signs of systems failure. From the fish in our oceans and rivers to bees which play a crucial role in our agricultural production, the decline of wildlife affects directly nutrition, food security and the livelihoods of billions of people.”
 
He added: “In the midst of a global pandemic, it is now more important than ever to take unprecedented and coordinated global action to halt and start to reverse the loss of biodiversity and wildlife populations across the globe, and protect our future health and livelihoods. Our own survival increasingly depends on it.”
 
The Living Planet Report 2020 presents an overview of the state of our natural world tracking trends in global wildlife abundance, with contributions from more than 125 experts from around the world. It shows that the main cause of the dramatic decline in species populations on land observed in the LPI is habitat loss and degradation, including deforestation, driven by how we as humanity produce food.
 
The LPI, which tracked almost 21,000 populations of more than 4,000 vertebrate species between 1970 and 2016, also shows that wildlife populations found in freshwater habitats have suffered a decline of 84 per cent - the starkest average population decline in any biome, equivalent to 4 per cent per year since 1970. One example is the spawning population of the Chinese sturgeon in China’s Yangtze river, which declined by 97 per cent between 1982 and 2015 due to the damming of the waterway.
 
“The Living Planet Index is one of the most comprehensive measures of global biodiversity,” said Dr Andrew Terry, Zoological Society of London’s Director of Conservation. “An average decline of 68% in the past 50 years is catastrophic, and clear evidence of the damage human activity is doing to the natural world. If nothing changes, populations will undoubtedly continue to fall, driving wildlife to extinction and threatening the integrity of the ecosystems on which we all depend. But we also know that conservation works and species can be brought back from the brink. With commitment, investment and expertise, these trends can be reversed.”
 
The LPR 2020 also includes pioneering modelling which shows that without further efforts to counteract habitat loss and degradation, global biodiversity will continue to decline. Based on a paper, ‘Bending the curve of terrestrial biodiversity needs an integrated strategy,’ co-authored by WWF and more than 40 NGOs and academic institutions and published in Nature, the modelling makes clear that stabilizing and reversing the loss of nature caused by humans’ destruction of natural habitats will only be possible if bolder, more ambitious conservation efforts are embraced and transformational changes made to the way we produce and consume food. Changes needed include making food production and trade more ecologically sustainable and favouring healthier and more environmentally-friendly diets.
 
The research shows that implementing these measures together rather than in isolation will allow the world to more rapidly alleviate pressures on wildlife habitats, thereby reversing biodiversity trends from habitat loss earlier than strategies that allow habitat losses and then attempt to reverse them later on. The modelling also indicates that if the world carries on with “business as usual”, rates of biodiversity loss seen since 1970 will continue over the coming years.
 
“These losses would at best take decades to reverse, and further irreversible biodiversity losses are likely, putting at risk the myriad ecosystem services that people depend on,” said David Leclère, lead author of the paper and Research Scholar at the International Institute of Applied System Analysis.
 
The Living Planet Report 2020 launches less than a week before the 75th session of the United Nations General Assembly, when leaders are due to set the direction for The Future We Want, including with a focus on protecting our planet.
 
A special Summit on Biodiversity, due to take place on 30 September, will bring together world leaders, businesses and civil society to highlight the urgent need for action on nature at the highest level. It marks a critical opportunity for leaders to demonstrate ambition and accelerate biodiversity action for sustainable development.
 
With a new global biodiversity agreement scheduled to be negotiated next year, alongside increased climate action, the world has the opportunity to secure a New Deal for Nature and People that sets nature on the path to recovery by 2030 and secures a sustainable future for people and the planet.
 
Lambertini said: “The Bending the Curve modelling provides invaluable evidence that if we are to have any hope of restoring nature to provide current and future generations of people with what they need, then world leaders must - in addition to conservation efforts - make our food system more sustainable and take deforestation - one of the main causes of wildlife population decline - out of supply chains.
 
“With leaders gathering for the UN General Assembly in a few days’ time, this research underlines to pressing need to secure a New Deal for Nature and People to realise the long-term survival of wildlife, plant and insect populations and the whole of nature, including humankind. A New Deal has never been needed more.”

The world has failed to meet a single target to stem the destruction of wildlife and life-sustaining ecosystems in the last decade, according to a devastating new report from the UN on the state of nature.
 
From tackling pollution to protecting coral reefs, the international community did not achieve any of the 20 Aichi biodiversity targets agreed in Japan in 2010 to slow the loss of the natural world. It is the second consecutive decade that governments have failed to meet targets.
 
The Global Biodiversity Outlook 5, published by the Convention on Biological Diversity before a key UN summit on the issue later this month, found natural habitats have continued to disappear, vast numbers of species remain threatened by extinction from human activities, and $500bn of environmentally damaging government fossil fuel subsidies have not been eliminated.
