UN Special Climate Report: 1.5ºC Is Possible But Requires Unprecedented and Urgent Action

New York, NY...The Special Report on Global Warming of 1.5ºC was approved by the IPCC on Saturday in Incheon, Republic of Korea. It will be a key scientific input into the Katowice Climate Change Conference in Poland in December, when governments review the Paris Agreement to tackle climate change.  “With more than 6,000 scientific references cited and the dedicated contribution of thousands of expert and government reviewers worldwide, this important report testifies to the breadth and policy relevance of the IPCC,” said Hoesung Lee, Chair of the IPCC.

Ninety-one authors and review editors from 40 countries prepared the IPCC report in response to an invitation from the United Nations Framework Convention on Climate Change (UNFCCC) when it adopted the Paris Agreement in 2015.

The report’s full name 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.

“One of the key messages that comes out very strongly from this report is that we are already seeing the consequences of 1°C of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes,” said Panmao Zhai, Co-Chair of IPCC Working Group I.

Limiting global warming 

The report highlights a number of climate change impacts that could be avoided by limiting global warming to 1.5ºC compared to 2ºC, or more. For instance, by 2100, global sea level rise would be 10 cm lower with global warming of 1.5°C compared with 2°C. The likelihood of an Arctic Ocean  free of sea ice in summer would be once per century with global warming of 1.5°C, compared with at least once per decade with 2°C. Coral reefs would decline by 70-90 percent with global warming of 1.5°C, whereas virtually all (> 99 percent) would be lost with 2ºC.

“Every extra bit of warming matters, especially since warming of 1.5ºC or higher increases the risk associated with long-lasting or irreversible changes, such as the loss of some ecosystems,” said Hans-Otto Pörtner, Co-Chair of IPCC Working Group II.

Limiting global warming would also give people and ecosystems more room to adapt and remain below relevant risk thresholds, added Pörtner. The report also examines pathways available to limit warming to 1.5ºC, what it would take to achieve them and what the consequences could be.

“The good news is that some of the kinds of actions that would be needed to limit global warming to 1.5ºC are already underway around the world, but they would need to accelerate,” said Valerie Masson-Delmotte, Co-Chair of Working Group I.

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,” said Jim Skea, Co-Chair of IPCC Working Group III.

Allowing the global temperature to temporarily exceed or ‘overshoot’ 1.5ºC would mean a greater reliance on techniques that remove CO2 from the air to return global temperature to below 1.5ºC by 2100. The effectiveness of such techniques are unproven at large scale and some may carry significant risks for sustainable development, the report notes.

“Limiting global warming to 1.5°C compared with 2°C would reduce challenging impacts on ecosystems, human health and well-being, making it easier to achieve the United Nations Sustainable Development Goals,” said Priyardarshi Shukla, Co-Chair of IPCC Working Group III.

The decisions we make today are critical in ensuring a safe and sustainable world for everyone, both now and in the future, said Debra Roberts, Co-Chair of IPCC Working Group II.

“This report gives policymakers and practitioners the information they need to make decisions that tackle climate change while considering local context and people’s needs. The next few years are probably the most important in our history,” she said.

Special Report

The Report was prepared under the scientific leadership of all three IPCC working groups. Working Group I assesses the physical science basis of climate change; Working Group II addresses impacts, adaptation and vulnerability; and Working Group III deals with the mitigation of climate change.The IPCC is the leading world body for assessing the science related to climate change, its impacts and potential future risks, and possible response options.

The Paris Agreement adopted by 195 nations at the 21st Conference of the Parties to the UNFCCC in December 2015 included the aim of strengthening the global response to the threat of climate change by “holding the increase in the global average temperature to well below 2°C above pre- industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels.”

As part of the decision to adopt the Paris Agreement, the IPCC was invited to produce, in 2018, a Special Report on global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways. The IPCC accepted the invitation, adding that the Special Report would look at these issues in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.

Global Warming of 1.5ºC is the first in a series of Special Reports to be produced in the IPCC’s Sixth Assessment Cycle. Next year the IPCC will release the Special Report on the Ocean and Cryosphere in a Changing Climate, and Climate Change and Land, which looks at how climate change affects land use.

The Summary for Policymakers (SPM) presents the key findings of the Special Report, based on the assessment of the available scientific, technical and socio-economic literature relevant to global warming of 1.5°C.

A pot plant growing in a puddle in Mtn. Ranch! My science tells me that the water is human pee! The world is ending, stop living immediately, no more breathing, subsist from using your body to accomplish anything your producing so much heat the glaciers are melting, refrain from driving your cars, someone will pay your bills because you can no longer go to. Work, the panacea is just in front of us, the really smart people know, why can't the other 99% see this! Oh my gosh, I forgot if we are pushing the ice age or global warming, oh well, that is why I might as well just smoke another reefer, oh no I can't, I would have to lite a match to do it, matches cause dish area, I can't do that because there isn't any mor butt wipe, all the paper mills have to close because the temp is going up! Please call 911 and see what we should do, better yet, call Al or Jerry, they have all the answers!

We pulled together as a nation during WWII. It wasn’t pretty, and it wasn’t nice. But we know how to pull together when we understand a threat like the Nazis, and now we clearly understand the catastrophic threat posed by global warming. We can do this. We don’t have to fight each other.

We can truly become “The Greatest Generation” and save the planet for all of God’s creatures. He’s given us technology, tenacity, inventiveness, and love.

Stop believing that we cannot do this. Stop listening to the voices of greed and hopelessness. We’ll have to work our asses off, but WE CAN DO IT.

      You say that because you're a climate scientist or is it because your tribe says it's a hoax?

      People who have the knowledge to know if it's true or a hoax say climate change/global warming is true. Almost all of them say that.

      BTW, for years and years after HIV was shown to be the cause of AIDS there were a few scientists who said that was not true. There may still be a few. But, HIV causes AIDS. It's the same thing with global warming. The fact that a few scientists say it's not true is not a valid reason for anyone else to believe it's not true.

    Can you explain how the many climate changes of the past happened, some quite rapidly, without human influence?
    How about the multitude of mass extinctions?
    While I am no fan of purposely polluting, you can't/shouldn't take away are advances without first offering/having a replacement that is eco-friendly and affordable and offers the same convenience. And no, everyone driving a Prius instead of a truck is not a solution.

    Yeah, but in WWII it wasn't a bunch of ragheads, fags, messicans, and liberal *bleep*heads running the country. Yes, we banded together. Now way too fractured a society to join in as one for a common cause.
