Scientists release ‘survival guide for humanity’ to avert climate disaster

SOURCE: (CNBC) A landmark U.N. report published Monday urged governments across the globe to embark on an urgent course correction to tackle the climate emergency, warning current plans were insufficient to prevent the worst of what the crisis has in store.

The U.N.’s Intergovernmental Panel on Climate Change said the unprecedented challenge of keeping global warming to 1.5 degrees Celsius above pre-industrial levels had become even greater in recent years due to the relentless increase in global greenhouse gas emissions.

This has resulted in more frequent and more intense extreme weather events that have caused increasingly dangerous impacts on nature and people in every region of the world, the report said.

Deep, rapid and sustained greenhouse gas emission reductions across all sectors will be necessary if warming is to be limited by 1.5 degrees Celsius, the report says, noting that global emissions should already be decreasing and will need to be slashed almost in half by 2030.

The 1.5 degrees Celsius temperature threshold is widely recognized as crucial because so-called tipping points become more likely beyond this level. Tipping points are thresholds at which small changes can lead to dramatic shifts in Earth’s entire life support system.

“Mainstreaming effective and equitable climate action will not only reduce losses and damages for nature and people, it will also provide wider benefits,” IPCC Chair Hoesung Lee said in a statement.

“This Synthesis Report underscores the urgency of taking more ambitious action and shows that, if we act now, we can still secure a liveable sustainable future for all.”

The IPCC’s Synthesis Report, approved during a week-long session in Interlaken, Switzerland, provides world leaders with a gold-standard summation of modern climate science. It is the first comprehensive report from the U.N. climate panel since the 2015 Paris Agreement and marks the closing chapter of the group’s sixth assessment cycle.

The findings, distilled from over 10,000 pages of research from six assessment reports, are expected to serve as a manual for tackling the climate emergency.

“The climate time bomb is ticking. But today’s IPCC report is a how-to guide to defuse the climate time bomb. It is a survival guide for humanity,” U.N. Secretary-General António Guterres said on Monday.

“As it shows, the 1.5-degree limit is achievable. But it will take a quantum leap in climate action.” Guterres described the report as a “clarion call to massively fast-track climate efforts by every country and every sector and on every timeframe.”

He added, “In short, our world needs climate action on all fronts — everything, everywhere, all at once.”

Speaking at a news conference, the U.N. chief announced a plan to “super-charge” climate efforts through an “all-hands-on-deck Acceleration Agenda.”

This initiative must see governments “hitting the fast-forward button” on their net zero deadlines, Guterres said, with rich countries urged to commit to reaching net zero as close as possible to 2040 and emerging economies called on to reach net zero by 2050.

The IPCC said Monday that there is more than enough global capital to rapidly reduce greenhouse gas emissions if existing barriers are removed.

The role of policymakers across the globe, the report’s authors say, is crucial in reducing these barriers, while investors, central banks and financial regulators can also “play their part.”

“Today’s message from the Intergovernmental Panel on Climate Change (IPCC) synthesis report is abundantly clear: we are making progress, but not enough,” U.S. climate envoy John Kerry said in a statement.

“We have the tools to stave off and reduce the risks of the worst impacts of the climate crisis, but we must take advantage of this moment to act now,” Kerry said.

The report’s findings also highlight the losses and damages the world is already experiencing — and will likely continue to face in the absence of effective climate action.

“Climate justice is crucial because those who have contributed least to climate change are being disproportionately affected,” said Aditi Mukherji, one of the 93 authors of this Synthesis Report.

“Almost half of the world’s population lives in regions that are highly vulnerable to climate change. In the last decade, deaths from floods, droughts and storms were 15 times higher in highly vulnerable regions,” she added.
