Limiting global warming to 1.5C would require urgent, far-reaching and unprecedented changes in all aspects of society according to a stark new report from the global scientific authority on climate change.
With clear benefits to people and natural ecosystems, limiting global warming to 1.5C compared to 2C could go hand-in-hand with ensuring a more sustainable and equitable society, say the authors of the report the UN’s Intergovernmental Panel on Climate Change (IPCC).
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 per cent 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.
“The good news is that some of the kinds of actions that would be needed to limit global warming to 1.5C are already underway around the world, but they would need to accelerate,” said Valerie Masson-Delmotte, Co-Chair of Working Group I.
The IPCC’s models emphasise the need for people to change their lifestyle and consumption patterns to more sustainable alternatives, specifically in areas they can control, like modes of transportation, the buildings they inhabit and their dietary preferences.
The difference between a world that is 1.5C warmer and one that is 2C warmer would be significant, the report said. It could be the difference between a world that is recognisable and one that is not.
The Special Report on Global Warming of 1.5C 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.

Its release reinforces the timeliness of the International Union of Health
Promotion and Education’s (IUHPE) 23rd World Conference on
Health Promotion conference in Rotorua from April 7 to 11 next year.
Co-hosted by the Health Promotion Forum of NZ the conference has as its theme WAIORA: Promoting Planetary Health and Sustainable Development for All.
As a theme, Waiora reflects the dependence of our own health on that of our planet, and recognises the major global challenge of balancing ongoing development with environmental stewardship.
