The UN’s 1.5°C special climate report at a glance

[Guest Post by Emil Jeyaratnam, Madeleine De Gabriele, and Michael Hopkin, originally published in The Conversation]

The Intergovernmental Panel on Climate Change released a special report today on the impacts of global warming of 1.5℃ above pre-industrial levels.

The report outlines the considerable challenges of meeting the Paris Agreement’s more ambitious goal of limiting warming to 1.5℃, the global effort needed to achieve the target, and the consequences of not.

The highlights of the report are presented below:

If the world was carbon neutral by: • 2047: we have a 66% chance of limiting warming to 1.5°C •2058: we have a 50% chance of limiting waeming to 1.5°C This will mean • sourcing 70 - 86% of electricity from renewables by 2050 • putting a price on greenhouse emissions • using technology to remove carbon dioxide from the atmosphere. GRAPH: Renewable energy targets | Proportion of global renewable energy consumption in 2015* = 18% | Global Target by 2050: 70 - 85% of electricity supplied by renewables | Australia: Australia's target for 2020: 23% | Labor's Target for 2030: 50% | souce: The World Bank | Text: The world has had about 1°C of warming so far. at 1.5°C we will see: • more heatwaves, floods and droughts • up to 90% of reef corals lost • damage to crops and fisheries • threats to economic growth | images: forest fire, flooded settlement, dead coral, dustbowl farmer's field | Text: But by avoiding 2°C of global warming, we will: • protect 10.4m people from sea level rise • halve the number of people without fresh water • reduce death and disease from heatwaves. • make it easier to deliver many of the UN's Sustainable Development GoalsCC BY-ND


Correction: A previous version of this article stated that the Australian Labor Party had a goal of reaching 50% renewable energy by 2050. But the ALP hope to achieve the 50% target via an emissions intensity scheme by 2030.
