Political will and urgent action required to save our planet, IPCC Report warns

IPCC 2018reportThe world’s climate science experts have spoken in the landmark report released by the Intergovernmental Panel on Climate Change (IPCC) on October 8.  The full title is: Global Warming of 1.5 °C: an IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty . That dry title doesn’t reflect the importance and impact of this report –  the first time that the UN body has modeled the difference between the impacts of the Paris agreement goals of 2°C and 1.5 °C, and an urgent, unanimous challenge by 91 scientists to the policy makers and politicians of the world to act on the solutions outlined in their models .  An IPCC official  quoted in a CBC report strikes the hopeful tone the report tries to achieve: “We have a monumental task in front of us, but it is not impossible… This is our chance to decide what the world is going to look like.”

The official report, commonly called  Global Warming 1.5  runs over 700 pages. The official press release  states:  “The report finds that limiting global warming to 1.5°C would require “rapid and far-reaching” transitions in land, energy, industry, buildings, transport, and cities. Global net human-caused emissions of carbon dioxide (CO2) would need to fall by about 45 percent from 2010 levels by 2030, reaching ‘net zero’ around 2050. This means that any remaining emissions would need to be balanced by removing CO2 from the air….Limiting warming to 1.5ºC is possible within the laws of chemistry and physics but doing so would require unprecedented changes”.  A 34-page Summary for Policymakers and a 3-page Headline Statements provide official summaries. Climate Home News offers  “37 Things you need to know about 1.5 global warming”  and  The Guardian offers summary and context in  “We must reduce greenhouse gas emissions to net zero or face more floods”  by Nicholas Stern and “We have 12 years to limit climate change catastrophe, warns UN”  (also republished in The National Observer) .

CAN CANADIANS EXPECT URGENT ACTION? :  A thorough CBC summary of the report appears in “UN Report on global warming carries life- or- death warning” , and the Globe and Mail published “UN Report on Climate Change calls for urgent action to avert catastrophic climate change”    (Oct 8) – yet no official reaction has been released by the federal government of Canada. “Trudeau’s Big Oil-friendly decisions mean climate chaos”  from Rabble.ca contrasts the IPCC report with a brief summary of Canada’s recent policy failures. “No change to Canada’s climate plans as UN report warns of losing battle” appeared in the National Observer (Oct. 8).  The National Observer also posted “We challenge every Federal and provincial leader to read the IPCC report and tell us what you plan to do” on October 9, characterizing Canada’s current divisions over a national carbon tax as representative of the world’s dilemma – the failure of political will to act on known scientific facts.  350.org Canada also addresses the issue of political will with  an online petition   calling for an emergency debate in the House of Commons on Canada’s plan to limit climate change, in light of the IPCC report.

Opinion Pieces are still being written, including:  “To avoid catastrophic climate change, we need carbon pricing” by Dale Beugin and Chris Ragan of the Ecofiscal Commission in the Globe and Mail  (Oct. 9) which argues that  “The best that economics has to offer is telling us we have a key solution right under our noses. Carbon pricing is now a Nobel Prize-winning idea. ”

On Climate, Our Choice Is Now Catastrophe or Mere Disaster ” by Crawford Kilian in The Tyee  . ….” modern governments and most of their voters are sleepwalking into catastrophe. If anyone or anything can wake them up, we might have a chance. And if we don’t work hard to turn that catastrophe into a mere disaster, we won’t be able to say nobody warned us. ”

“Canada’s carbon-tax plan is collapsing just as the planet runs out of time” in the Washington Post (Oct. 9)…. ” Today, Canadians should take a minute to write to their elected officials provincially and federally and demand that we get the carbon tax done. Every elected official should take a moment to decide how they would like to be remembered. That is, assuming there will be anyone around to remember.”

WELL-INFORMED GLOBAL SUMMARIES :IPCC: Radical Energy Transformation Needed to Avoid 1.5 Degrees Global Warming”   and “Not Just CO2: These Climate Pollutants Also Must Be Cut to Keep Global Warming to 1.5 Degrees”appeared  in Inside Climate News. The World Resources Institute published “8 Things You Need to Know About the IPCC 1.5˚C Report” , accompanied by a  blog and infographic which  explains the consequential difference between 1.5 and 2.0 global warming levels. Climate Action International monitored the discussions leading up to the release of the report: here is their summary and a compilation of global reactions . A compilation of reactions from the academics at Imperial College and the Grantham Research Institute on Climate Change and the Environment (LSE) is here.

A brief Comment was already issued by the policy and communications director of the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science, which calls the report a “conservative assessment” because it omits discussion of some of the largest risks and their impacts – notably  population displacements, migration and possibly conflict, as well as  potential climate  ‘tipping points’, such as disruption to the Gulf Stream in the Atlantic and shifts in the monsoon in Africa and Asia.

Another key issue: the controversial role of geoengineering, such as carbon capture and storage or “carbon dioxide removal technologies”(CDR) .  “Negative Emissions technologies in the new report on limiting global warming” was posted at Legal Planet (Oct. 8) , pointing out how important geoengineering is in the report’s models. The author argues that ”  …. The text of the relevant chapter is honest about large-scale negative emissions, when it states:  “Most CDR  technologies remain largely unproven to date and raise substantial concerns about adverse side-effects on environmental and social sustainability. ” But the author argues that the message was deliberately watered down  in the executive summaries and in the Summary for Policymakers.

On October 4, just before the release of Global Warming 1.5, 110 organizations and social movements, led by Friends of the Earth International, released their Hands Off Mother Earth! Manifesto, which opposes any geoengineering solutions, including carbon capture and storage.

It’s hard to overestimate the importance of this report, and it will draw more and more discussion as the UNFCCC meetings in Katowice, Poland approach in December 2018.
