IPCC adaptation report ‘a damning indictment of failed global leadership on climate’

“This report is a dire warning about the consequences of inaction,” said Hoesung Lee, Chair of the Intergovernmental Panel on Climate Change (IPCC).

“It shows that climate change is a grave and mounting threat to our wellbeing and a healthy planet. Our actions today will shape how people adapt and nature responds to increasing climate risks,” he said, adding: “Half measures are no longer an option.”

According to the report, human-induced climate change is causing dangerous and widespread disruption in nature and affecting billions of lives all over the world, despite efforts to reduce the risks, with people and ecosystems least able to cope being hardest hit.

This is the second in a series of three reports from the the UN’s top climate scientists and its launch comes just over 100 days since the UN climate action summit in Glasgow, COP26, agreed to step up action to limit global warming to 1.5°C and stave off the worst effects of climate change.

UN Secretary-General António Guterres called the first report, issued last August, a “code red for humanity“, and said that “If we combine forces now, we can avert climate catastrophe.”

‘Clobbered by climate change’

His take on the latest report is equally stark: he laments that the evidence detailed by IPCC is unlike anything he has ever seen, calling it an “atlas of human suffering and a damning indictment of failed climate leadership.”

With fact upon fact, this report, which focuses on impacts, adaptation and vulnerability, reveals how people, and the planet, are getting “clobbered” by climate change.

“Nearly half of humanity is living in the danger zone – now. Many ecosystems are at the point of no return – now. Unchecked carbon pollution is forcing the world’s most vulnerable on a frog march to destruction – now,” he declared.

Criminal abdication of leadership

Mr. Guterres said the world’s biggest polluters are guilty of arson of our only home.

In the face of such dire evidence, it is essential to meet the goal of limiting global temperature rise to 1.5 degrees, and the science shows that will require the world to cut emissions by 45 percent by 2030 and achieve net zero emissions by 2050.

“But according to current commitments, global emissions are set to increase almost 14 per cent over the current decade. That spells catastrophe. It will destroy any chance of keeping 1.5 alive,” said the UN chief.

One of the report’s core truths is that coal and other fossil fuels are choking humanity, the Secretary-General explained, calling on all G20 governments to live up to their agreements to stop funding coal abroad, and the must now urgently do the same at home and dismantle their coal fleets.

Moreover, he said that oil and gas giants – and their underwriters – are also on notice. “You cannot claim to be green while your plans and projects undermine the 2050 net-zero target and ignore the major emissions cuts that must occur this decade. People see through this smokescreen.”

Instead of slowing down the decarbonization of the global economy, now is the time to accelerate the energy transition to a renewable energy future, he said declaring fossil fuels a “dead end for our planet, for humanity, and yes, for economies,” and calling for developed countries, Multilateral Development Banks, private financiers and others to form coalitions to help major emerging economies end the use of coal.

Adaptation saves lives

The second core finding from he IPCC report is slightly better news: investments in adaptation work.

“As climate impacts worsen – and they will – scaling up investments will be essential for survival. Adaptation and mitigation must be pursued with equal force and urgency. That’s why I have been pushing to get to 50 per cent of all climate finance for adaptation,” Mr. Guterres explained.

Noting that the Glasgow commitment on adaptation funding is clearly not enough to meet the challenges faced by nations on the frontlines of the climate crisis he said that he is also pressing to remove the obstacles that prevent small island states and least developed countries from getting the finance they desperately need to save lives and livelihoods.

Delay means death

“We need new eligibility systems to deal with this new reality. Delay means death,” he said.

Saying that he is taking inspiration from all those on the frontlines of the climate battle fighting back with solutions, the Secretary-General said that he knew people everywhere were anxious and angry.

“I am, too. Now is the time to turn rage into action. Every fraction of a degree matters. Every voice can make a difference. And every second counts.

Urgent action to tackle increasing risks

The IPCC says that increased heatwaves, droughts and floods are already exceeding plants’ and animals’ tolerance thresholds, driving mass mortalities in species such as trees and corals. These weather extremes are occurring simultaneously, causing cascading impacts that are increasingly difficult to manage.

They have exposed millions of people to acute food and water insecurity, especially in Africa, Asia, Central and South America, on Small Islands and in the Arctic.

To avoid mounting loss of life, biodiversity and infrastructure, ambitious, accelerated action is required to adapt to climate change, at the same time as making rapid, deep cuts in greenhouse gas emissions.

So far, progress on adaptation is uneven and there are increasing gaps between action taken and what is needed to deal with the increasing risks, the new report finds. These gaps are largest among lower-income populations.

“This report recognizes the interdependence of climate, biodiversity and people and integrates natural, social and economic sciences more strongly than earlier IPCC assessments,” said Hoesung Lee.

Protecting nature is key to securing a liveable future

There are options to adapt to a changing climate. This report provides new insights into nature’s potential not only to reduce climate risks but also to improve people’s lives, the IPCC says.

“Healthy ecosystems are more resilient to climate change and provide life-critical services such as food and clean water”, said IPCC Working Group II Co-Chair Hans-Otto Pörtner.

“By restoring degraded ecosystems and effectively and equitably conserving 30 to 50 per cent of Earth’s land, freshwater and ocean habitats, society can benefit from nature’s capacity to absorb and store carbon, and we can accelerate progress towards sustainable development, but adequate finance and political support are essential.”

Scientists point out that climate change interacts with global trends such as unsustainable use of natural resources, growing urbanization, social inequalities, losses and damages from extreme events and a pandemic, jeopardizing future development.

“Our assessment clearly shows that tackling all these different challenges involves everyone – governments, the private sector, civil society – working together to prioritize risk reduction, as well as equity and justice, in decision-making and investment,” said IPCC Working Group II Co-Chair Debra Roberts.

Cities: Hotspots of climate risks; crucial to the solution

The report provides a detailed assessment of climate change impacts, risks and adaptation in cities, and urban areas, where more than half the world’s population lives.

“Together, growing urbanization and climate change create complex risks, especially for those cities that already experience poorly planned urban growth, high levels of poverty and unemployment, and a lack of basic services,” Ms. Roberts said.

“But cities also provide opportunities for climate action – green buildings, reliable supplies of clean water and renewable energy, and sustainable transport systems that connect urban and rural areas can all lead to a more inclusive, fairer society.”

Rapidly closing window for action

Overall, the report, which provides extensive regional information to enable Climate Resilient Development, underlines the urgency for climate action, focusing on equity and justice.

Adequate funding, technology transfer, political commitment and partnership lead to more effective climate change adaptation and emissions reductions.

“The scientific evidence is unequivocal: climate change is a threat to human wellbeing and the health of the planet. Any further delay in concerted global action will miss a brief and rapidly closing window to secure a liveable future,” said Hans-Otto Pörtner.
