IPCC reporting hiatus could imperil political action on climate change

The Intergovernmental Panel on Climate Change (IPCC) today released its latest report on the state of global warming. Current plans begin a five-year hiatus between future renewals. However, given the pressing need for climate change to remain at the forefront of political and social agendas over the next decade, campaigners are asking scientific bodies to consider moving to a system of annual reports. I am asking for

“The impact of the IPCC on government decision-making cannot be overstated,” said Louise Burrows of climate think tank E3G. “The evidence it produces will be invaluable in securing new policies and driving the scale and ambition of climate action.”

Today’s IPCC report marks the end of the sixth assessment cycle since 2018, which has regularly published major papers on warming impacts above 1.5.°C and the threat it poses to the world’s land and sea. There were also three major updates on the physical sciences of climate change, its impacts, and strategies for addressing the problem.

Steven Cornelius of the conservation group WWF said the IPCC report has proven “extremely influential” in changing governments and public opinion around the world. Since the Panel’s report on warming above 1.5°Since C was launched in 2018, many countries have backed their climate ambition, with 80% of the global economy now covered by net-zero targets.

but, you areUnder the current IPCC timetable, the next reporting cycle will not deliver new interventions until 2027 or 2028. Some campaigners warn that the gap could erode political momentum for action. Burroughs, for example, warns that interruptions will mark “the loss of the coercion mechanism that drives ambition.”

Some are calling for the IPCC to completely overhaul its reporting regime in response to this threat. Kaisa Kosonen of the campaign organization Greenpeace International said:

The IPCC had previously warned that limiting global temperature rise to 1.5 would require a 45% reduction in global emissions by 2030 compared to 2010 levels.°C. As such, the 2020s will be a critical decade, requiring regular intervention by the IPCC.says Kosonen.

“I certainly believe that the IPCC should be open to bold reforms, so that the IPCC can be more agile, prepare products and other activities on a shorter timeline, and have a transition period. We can meet new needs and stay focused in this critical decade,” she says.

Mike Hulme, University of Cambridge – co-editor of A critical assessment of the Intergovernmental Panel on Climate Change – A move to regular IPCC reporting could be a useful tool to “bring people’s attention to the problem” of climate change, it said.

“Why not just do an annual update of what we’ve discovered in the last 12 months, but also do such a large exercise that takes 6-7 years to generate 5 million words?” he says.

This issue has been actively debated among IPCC authors. “this is something we talk about endlessinformally say Peter Thorne of Maynooth University in Ireland is part of the core writing team for the integrated report released today.

However, Thorne is concerned that the move to annual reporting will significantly increase the burden on scientists producing IPCC reports. He warned that it would be “a huge demand” for scientists, keeping experts away from primary research.

He also worries that IPCC reports will lose their weight if they are published on an annual basis. “Part of the power of these is that they are seeing a tremendous increase in knowledge. Five to seven years he could literally have enough literature and new innovations. he says. “There is value in maintaining the status quo model of [reporting] Every 5 to 7 years. ”
