Global Warming of 1.5C: Will you listen please?

Thursday 25 October 2018

More warming, higher seas. Maybe much higher. Could wake sleeping giants.

Communicating the findings of the IPCC 1.5C report on Global Warming can be done in 866 pages or condensed down to 17 sylablles. Scroll down to the bottom of the page for a comparative chart.

On October 8th, the Intergovernmental Panel on Climate Change published their Report on Global Warming of 1.5oC.   The findings have enormous implications for our society – the report highlights the need for urgent action if we want to keep climate change within safe limits and reduce extreme weather events, heat-related morbidity and food shortages.

But how do we ensure that people are actually understanding the implications and taking action accordingly?

At 866 pages, based on more than 6,000 research papers (equivalent to a four storey building if they were all stacked on top of each other) the scale, depth and breadth of the report can be daunting.   Even the Summary for policy makers runs to 33 pages.   The three page Headline statements are certainly shorter - but are there other ways to get the message across?

Since the launch of the report, scientists, journalists and commentators have all been exploring the best ways to effectively communicate its findings in an increasingly noisy and crowded world.   

“I've tried to condense the message down to its absolute essence," says Prof Mark Howden, IPCC Vice Chair, Review Editor of the report and Director of the ANU Climate Change Institute, "and here it is:  

Every half a degree matters, every year matters, every choice matters.

Or a longer version: 

Every half a degree matters, with unwanted climate change impacts.   The Carbon budget for a two thirds chance to stay below 1.5C will be gone in 10 to 14 years.   So every year matters.  Many options are laid out in the report with differing implications.  So every choice matters.”

And we thought this Haiku (a traditional Japanese poem of 17 syllables), written by IPCC Vice Chair and Contributing Author, Andy Reisinger, was powerful in its simplicity and worth highlighting as a great way of communicating the key messages of the report.  Here's the first verse:

We wrote this report

at your request, and with care.

Will you listen please?

 

It's well worth reading the full haiku (of 19 verses including references to relevant sections of the report) here.   Or here are the 19 verses on their own:

We're at 1 degree

now and will hit 1.5

within three decades.

 

Past emissions will

warm the Earth for centuries -

but there's still a choice.

 

Climate risk increase

with every half degree.

Some are real now.

 

More warming, higher

seas. Maybe much higher. Could

wake sleeping giants.

 

Warming is bad news

for many species. Once gone,

we can't bring them back.

 

People are affected

by all this; some will struggle

much more than others.

 

1.5 degrees

needs global carbon-zero

by 2050.

 

All emission paths

to 1.5 degrees cut

methane hard and fast.

 

Carbon budgets are

uncertain but either way

quickly depleted.

 

Reduced emissions

won't be enough. Put carbon

back where it belongs.

 

Feed more people and

remove carbon at large scale -

in models yes, but...?

 

 

Current NDCs

across countries won't achieve

what we agreed to.

 

 

Rapid reductions

demand unprecedented

transformations now.

 

1.5 degrees

needs higher carbon prices

to make it happen.

 

 

Policies can drive

investment, innovation,

and behaviour change.

 

There are so many

synergies with SDGs:

Use them or lose them.

 

Adapt, mitigate

and develop: with great care

we could have it all.

 

Good development

helps climate, and good climate

helps development.

 

The length of these different forms of communication vary by a factor of over 43,000.    Each form of communication has its place;  the full report is powerful beause of its incredible rigour and depth whilst the brevity of Prof Mark Howden's quote and the Haiku can help make the report's findings easily comprehensible and more emotionally engaging.    So finally, again “Will you listen please …?”
