IPCC Special Report on 1.5ºC
— gavin @ 7 October 2018
Responding to climate change is far more like a marathon than a sprint.
The IPCC 1.5ºC Special report (#SR15) has been released:
It’s well worth reading the SPM and FAQs before confidently pronouncing on the utility or impact of this report. The FAQs include the following questions:
- FAQ 1.1: Why are we talking about 1.5°C?
- FAQ 1.2: How close are we to 1.5°C?
- FAQ 2.1: What kind of pathways limit warming to 1.5°C and are we on track?
- FAQ 2.2: What do energy supply and demand have to do with limiting warming to 1.5°C?
- FAQ 3.1: What are the impacts of 1.5°C and 2°C of warming?
- FAQ 4.1: What transitions could enable limiting global warming to 1.5°C?
- FAQ 4.2: What are Carbon Dioxide Removal and negative emissions?
- FAQ 4.3: Why is adaptation important in a 1.5°C warmer world?
- FAQ 5.1: What are the connections between sustainable development and limiting global warming to 1.5°C?
- FAQ 5.2: What are the pathways to achieving poverty reduction and reducing inequalities while reaching the 1.5°C world?
First thing to remember is that this special report was commissioned from the UNFCCC on the back of the Paris Accord (which is not the process for main IPCC reports). Secondly, the IPCC is constrained to only assess published literature or otherwise publically available data. This means that if no groups have studied a question, there isn’t much to assess. Sometimes the gaps are apparent even in the scoping of the reports which can encourage people to focus on them at an early stage and have publications ready in time for the final report, but one of the main impacts of any of these reports is to influence research directions going forward.
