On the 9th of August 2021, the Intergovernmental Panel on Climate Change (IPCC) published the IPCC Working Group I sixth assessment report (AR6,I). The report addresses the most up-to-date physical understanding of the climate system and climate change. UN Secretary-General António Guterres, classified the report as a “code red for humanity”. Does it mean it is too late to do anything? Of course not! Let’s review why and more especially what you can do, no matter where you are up to in your climate or ecological journey.
What is the IPCC and what is the AR6?
The IPCC is an intergovernmental body of the United Nations, mandated to provide objective scientific information relevant to understanding human-induced climate change, its natural, political, and economic impacts and risks, and possible response options. The IPCC does not conduct original research nor monitor climate change; rather, it undertakes a systematic review of all relevant published literature to provide a comprehensive update on climate change, its effects, and potential strategies.
This AR6-I summarises 14 000 scientific papers and was voluntarily written by 234 experts, who responded to 78 007 comments from government bodies and experts.
For this first volume, the focus is on the physical understanding of the climate system and climate change. There are three versions you can review (with strong advice to start with SPM):
- Summary for Policymakers (SPM, 42 pages)
- Technical summary (TS, 159 pages)
- Complete report (3949 pages)
What does this report tell us? Where are we now and where are we heading to?
The SPM will give you the full picture of what is the current state of the climate, what are the possible futures and how we can limit future climate change (including key numbers).
The following points are important to memorise, and more importantly to share around you.
The current state of climate
- Human influence has univocally warmed the atmosphere, ocean and land. Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred.
- 100% of global warming is due to human activities (see figure 1 comparing the observed warming compared to human influence)
- The magnitude of recent climate system changes and the current state of many parts of the climate system are unprecedented, from centuries to thousands of years (CO2 concentrations, global surface temperature, sea level rise, ocean acidification, etc.)
- Human-induced climate change is already affecting many weather and climate extremes in every region across the globe, as seen in the last months across the world: heatwaves, heavy precipitation, droughts, and bush fires.
Possible climate futures
- Global surface temperature will continue to increase until at least the mid-century under all emissions scenarios considered. Global warming of 1.5°C and 2°C will be exceeded during the 21st century unless deep and quick reductions in CO2 and other greenhouse gas emissions occur in the coming decades.
- Many changes in the climate system become larger in direct relation to increasing global warming. They include increases in the frequency and intensity of hot extremes, marine heatwaves, and heavy precipitation, agricultural and ecological droughts in some regions, and proportion of intense tropical cyclones, as well as reductions in Arctic sea ice, snow cover and permafrost.
- Continued global warming is projected to further intensify the global water cycle, including its variability, global monsoon precipitation and the severity of wet and dry events.
- If CO2 emissions continue to increase at the current scale, the ocean and land carbon sinks are projected to be less effective at slowing the accumulation of CO2 in the atmosphere, meaning more CO2 will accumulate into the atmosphere.
- Any changes due to past and future greenhouse gas emissions are irreversible for centuries to millennia, especially changes in the ocean, ice sheets and global sea level.
How will it look in Australia and other regions?
You can go through this 2 pages factsheet for Australasia. There is also an interactive Atlas to look at other parts of the world and better understand that climate change manifests differently depending on where you live.
- The impacts at +2℃ are much worse than at +1.5℃ . Each fraction of degree counts! And so every GHG emission we can prevent counts!
Limiting Future Climate Change
We need to reach net-zero CO2 emissions as soon as possible (and preferably before 2050), along with a reduction in other greenhouse gas emissions (methane, nitrous oxide). Not only will it limit further climate change, but it will also improve air quality and the life of both humans, animals, and all living species on Earth.
Now that you know, what can you do?
First, I would advise you to let the emotions and feelings submerge you. Express them in the way you wish and don’t try to hide them in a corner of your brain, that’s how you may not move towards action or feel too small to do anything. In my case, a long run or walk in nature listening to birds, looking at trees and plants, helps me to reconnect and feel that I am part of this beautiful planet, and I can’t close my eyes to what is happening.

There are thousands of articles, podcasts, books, courses, videos, etc, to follow. Once you start opening the climate box, you will then want to understand ecology, biodiversity, social justice, waste pollution, or even psychology. That’s why it is important to always remember why you start something, and where you want to go: What is your intention?

I hope that this article clarified what you didn’t know about climate change and the latest IPCC report. But more importantly, I hope that you now feel empowered to either start or continue your climate (and more broadly your ecological) journey.
Leave a comment with any question, or any suggestion of a blog article we could write to follow up on this one! Take care.
