If the latest warnings contained in Monday's report by the Intergovernmental Panel on Climate Change (IPCC)—which included pronouncements that the world has less than twelve years to drastically alter course to avoid the worst impacts of human-caused global warming and that nothing less than keeping all fossil fuels in the ground is the solution to avoid future calamities—have you at all frightened or despondent, experts responding to the report have a potentially unwelcome message for your already over-burdened heart and mind: It's very likely even worse than you're being told.

"The IPCC understates a key risk: that self-reinforcing feedback loops could push the climate system into chaos before we have time to tame our energy system."

—Mario Molina, Nobel Laureate

After the report's publication there were headlines like: "We have 12 years to act on climate change before the world as we know it is lost. How much more urgent can it get?" and "Science pronounces its verdict: World to be doomed at 2°C, less dangerous at 1.5°C" and "A major new climate report slams the door on wishful thinking."

But as Jamie Henn, co-founder and the program director for the international climate group 350.org, stated in a tweet on Tuesday, the "scariest thing about the IPCC Report" is the fact that "it's the watered down, consensus version. The latest science is much, much, much more terrifying."

Henn was actually responding to Penn State University climate scientist Michael Mann who was pushing back against those criticizing the IPCC report as too "alarmist" in its declarations and warnings. "If anything," Professor Mann declared, "it is the opposite. Once again, with their latest report, they have been overly conservative (ie. erring on the side of understating/underestimating the problem.)"

This is very possibly true and there is much scientific data and argument backing this up. As Henn and Mann both indicate, the IPCC report is based on the consensus view of the hundreds of scientists who make up the IPCC – and its been consistently true that some of the most recent (and increasingly worrying) scientific findings have not yet found enough support to make it into these major reports which rely on near-unanimous agreement.

According to Durwood Zaelke, founder of the Institute for Governance and Sustainable Development, speaking to The Guardian in the wake of the latest IPCC report, it "fails to focus on the weakest link in the climate chain: the self-reinforcing feedbacks which, if allowed to continue, will accelerate warming and risk cascading climate tipping points and runaway warming."

"This is not the time to turn away, whether in fear or in active denial of the facts. This is a time to use our fear as fuel."

—Rajiv Sicora, The LeapIn August, as Common Dreams reported, research published by Johan Rockström and his colleagues at the Stockholm Resilience Centre in Sweden found that it is precisely these feedback loops and tipping points that should most frighten and concern humanity. While nascent and not conclusive in its findings—two of the reasons you won't find it referenced in the IPCC report—the study warned that humanity may be just 1°C away from creating a series of dynamic feedback loops that could push the world into a climate scenario not seen since the dawn of the Helocene Period, nearly 12,000 years ago.

Quoted in Tuesday's Guardian article about the dangers of ignoring potential tipping points, Nobel prize laureate Mario Molina, who shared the award for chemistry in 1995 for his work on ozone depletion, said: "The IPCC report demonstrates that it is still possible to keep the climate relatively safe, provided we muster an unprecedented level of cooperation, extraordinary speed and heroic scale of action. But even with its description of the increasing impacts that lie ahead, the IPCC understates a key risk: that self-reinforcing feedback loops could push the climate system into chaos before we have time to tame our energy system, and the other sources of climate pollution."

The purpose of recognizing the terrifying predictions is not to instill fear, however, climate campaigners and advocates for bold solutions say.

In a paper authored last year—titled Leading the Public into Emergency Mode: A New Strategy for the Climate Movement—Margaret Klein Salamon writes that while a World War II-style mobilization is necessary to achieve the kind emission cuts and energy transformation that science now mandates, understanding the stakes does not necessarily mean being debilitated by that knowledge. In an op-ed for Common Dreams, she argued "that intense, but not paralyzing, fear combined with maximum hope can actually lead people and groups into a state of peak performance. We can rise to the challenge of our time and dedicate ourselves to become heroic messengers and change-makers."

And as Rajiv Sicora, senior manager of research for The Leap, wrote to his group's supporters in an email on Tuesday: "This is not the time to turn away, whether in fear or in active denial of the facts. This is a time to use our fear as fuel: because the report also makes clear that the worst effects of global warming can still be prevented, and the urgency of transformative change should excite and empower all of us who are fighting for justice anyway."
