The report, which draws on 6,000 research papers, was prepared by the IPCC's, examined the science of climate change, the impact of it and how it can be mitigated.
A United Nations report on Monday said that temperatures are likely to rise by 1.5 degrees Celsius between 2030 and 2052 if global warming continues at its current pace and if humanity fails to take rapid steps to curb the problem.
The report summary said renewable energy would need to supply 70 per cent to 85 per cent of electricity by 2050 to stay within a 1.5C limit, compared with about 25 per cent now.
"We are already seeing the consequences of 1 degree of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice", said Panmao Zhai, one of the co-chairs who helped bring together the report by the researchers who reviewed thousands of scientific papers.
Scottish Greens' co-convener Patrick Harvie said: "We've always challenged the government to go further in its response to unsafe climate change".
Meeting the tougher-to-reach 1.5C goal "could result in around 420 million fewer people being frequently exposed to extreme heat waves, and about 65 million fewer people being exposed to exceptional heat waves", the report says.The deadly heat waves that hit India and Pakistan in 2015 could become practically yearly events if the world becomes hotter.
Limiting global warming will require "far-reaching and unprecedented changes" to human behaviour, according to the panel.
By the decade 2006-2015, 20 to 40 per cent of the global population had already experienced warming of 1.5°C in at least one season.
Why limiting global warming to 1.5 degrees is crucial?
That's not lost on Jones.
Jones past year established the Carbon Risk Initiative, a database that includes information on the amount of oil, gas, coal and utilities investments held by insurance companies, and whether the insurers have divested from thermal coal, the amount of thermal coal divested and any future commitments to divest.
Also in Geneva, a United Nations rights expert warned that failing to do more to address climate change risked "locking in decades" of grave violations.
The authors of the IPCC report estimate economic damages from flooding, drought, and other effects by 2040 of $54 trillion.
Statistically significant reductions in per capita GDP growth are projected in most of Africa, Southeast Asia, India, Brazil and Mexico, the report notes.
"Limiting warming to 1.5ºC is possible within the laws of chemistry and physics but doing so would require unprecedented changes", said Jim Skea, Co -Chair of IPCC Working Group III which worked on the report.
"We've seen how quickly consumer opinion could shift", Martin said.
Here is what you need to know. "There is no time to waste", he said.
"The scale of all the changes that we are experiencing in the climate system is unprecedented, the scale of the changes that humans would have to implement in order to keep climate change under control is unprecedented", report co-author Hans-Otto Portner told reporters in South Korea on Monday. In the Paris accord, 197 countries agreed to the goal of holding global temperatures "well below" 2°C above pre-industrial levels and to pursue efforts to limit it to 1.5°C.
She added: "The insurance sector does have a keen interest in attaining 1.5°C and limiting temperature rise to no more than that given everything that is at risk on both the product side and the investment side".
