‘Tipping point’ for climate action: Time’s running out to avoid catastrophic heating

According to the landmark United in Science 2021, there “is no sign of growing back greener”, as carbon dioxide emissions are rapidly accelerating, after a temporary blip in 2020 due to COVID, and nowhere close to the targets set by the Paris Agreement.

 “We have reached a tipping point on the need for climate action. The disruption to our climate and our planet is already worse than we thought, and it is moving faster than predicted”, UN Secretary General António Guterres underscored in a video message. “This report shows just how far off course we are”, he added.

A world in danger

According to scientists, the rising global temperatures are already fueling devastating extreme weather events around the world, with escalating impacts on economies and societies. For example, billions of working hours have been lost due to excessive heat.

“We now have five times the number of recorded weather disasters than we had in 1970 and they are seven times more costly. Even the most developed countries have become vulnerable”, said the UN chief.

Mr. Guterres cited how Hurricane Ida recently cut power to over a million people in New Orleans, and New York City was paralysed by record-breaking rain that killed at least 50 people in the region.

“These events would have been impossible without human-caused climate change. Costly fires, floods and extreme weather events are increasing everywhere. These changes are just the beginning of worse to come”, he warned.

A bleak future

The report echoes some of the data and warnings from experts in the last year: the average global temperature for the past five years was among the highest on record, and there is an increasing likelihood that temperatures will temporarily breach the threshold of 1.5° Celsius above the pre-industrial era, in the next five years.

The picture painted by United in Science is bleak: even with ambitious action to slow greenhouse gas emissions, sea levels will continue to rise and threaten low-lying islands and coastal populations throughout the world.

“We really are out of time. We must act now to prevent further irreversible damage. COP26 this November must mark that turning point. By then we need all countries to commit to achieve net zero emissions by the middle of this century and to present clear, credible long-term strategies to get there”, urged the UN chief.

The 2021 United Nations Climate Change Conference, also known as COP26, is scheduled to be held in the city of Glasgow, Scotland between 31 October and 12 November 2021. The pivotal meeting is expected to set the course of climate action for the next decade.

We must urgently secure a breakthrough on adaptation and resilience, so that vulnerable communities can manage these growing (climate) risks…I expect all these issues to be addressed and resolved at COP26. Our future is at stake”, Mr. Guterres emphasized.

“Throughout the pandemic we have heard that we must “build back better” to set humanity on a more sustainable path, and to avoid the worst impacts of climate change on society and economies. This report shows that so far in 2021, we are not going in the right direction”, added Prof. Petteri Talas, World Meteorological Organization’s secretary general.

The report also cites the conclusions of the most recent IPCC report: the scale of recent changes across the climate system are unprecedented over many centuries to many thousands of years, and it is unequivocal that human influence has warmed the atmosphere, ocean and land.

Notable findings

Concentrations of the major greenhouse gases – carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2 O) continued to increase in 2020 and the first half of 2021.

According to WMO, reducing atmospheric methane (CH4) in the short term, could support the pledges of 193 Member States made in Paris. This measure does not reduce the need for strong, rapid and sustained reductions in CO2 and other greenhouse gases.

Meanwhile, the UN Environment Program (UNEP), warns that five years after the adoption of the Paris Agreement, the emissions gap (the difference between where emissions are heading and where science indicate they should be in 2030) is as large as ever.

Although the increasing number of countries committing to net-zero emission goals is encouraging, to remain feasible and credible, these goals urgently need to be reflected in near-term policy and in significantly more ambitious actions, the agency highlights.

A warmer future

The report explains that the annual global average temperature is likely to be at least 1 °C warmer than pre-industrial levels (defined as the 1850–1900 average) in each of the coming five years and is very likely to be within the range of 0.9 °C to 1.8 °C.

There is also a 40% chance that the average temperature in one of the next five years, will be at least 1.5 °C warmer than pre-industrial levels. However, it is very unlikely that the 5-year average temperature for 2021–2025 will pass the 1.5 °C threshold.

High latitude regions, and the Sahel, are likely to be wetter in the next five years, the report also warns.

Sea level rise is inevitable

Global sea levels rose 20 cm from 1900 to 2018, and at an accelerated rate from 2006 to 2018.

Even if emissions are reduced to limit warming to well below 2 °C, the global average sea level would likely rise by 0.3–0.6 m by 2100 and could rise 0.3–3.1 m by 2300.

Adaptation to the rise will be essential, especially along low-lying coasts, small islands, deltas and coastal cities, explains WMO.

World’s health also at risk

The World Health Organization (WHO) warns that rising temperatures are linked to increased heat-related mortality and work impairment, with an excess of 103 billion potential work hours lost globally in 2019 compared with those lost in 2000.

Moreover, COVID-19 infections and climate hazards such as heatwaves, wildfires and poor air quality, combine to threaten human health worldwide, putting vulnerable populations at particular risk.

According to the UN health agency, the COVID-19 recovery efforts should be aligned with national climate change and air quality strategies to reduce risks from cascading climate hazards, and gain health co-benefits.

The United in Science 2021 report, the third in a series, is coordinated by the World Meteorological Organization (WMO), with input from the UN Environment Programme (UNEP), the World Health Organization (WHO), the Intergovernmental Panel on Climate Change (IPCC), the Global Carbon Project (GCP), the World Climate Research Programme (WCRP) and the Met Office (UK). It presents the very latest scientific data and findings related to climate change to inform global policy and action.
