In any non-nightmarish scenario, world leaders would gather together upon receipt of this report, generated by highly respected scientists at the top of their game (the Intergovernmental Panel on Climate Change), and work overtime to solve the global and systemic problems stemming from overuse of dirty energy sources such as coal and the mass production of greenhouse gases, for two.
The IPCC's report, 'Global Warming of 1.5ºC, ' an outcome of the Paris Agreement goal to limit the global temperature rise in this century to well below 2° Celsius above pre-industrial levels and to pursue efforts to cap the temperature increase at 1.5° C, could create conditions to resolve these issues. Even less than a degree increase in the global temperature would risk destroying the coral reefs, the Antarctic ice sheets and crops, as well as make the ocean more acidic.
It furthers the Paris Agreement of 2015, where and aim of limiting global temperature rises to "well below" 2C was set.
Another recent report from the consulting firm PwC makes it clear that even limiting warming to 2 degrees C will be a stretch: "There seems to be nearly zero chance of limiting warming to well below two degrees (the main goal of the Paris Agreement), though widespread use of carbon capture and storage technologies, including Natural Climate Solutions, may make this possible", it says.
The report compares the impacts of warming at 1.5°C against 2°C across the planet - from ecosystems on land and in oceans to the health and well being of people - and finds universal benefits in the lower target, such as 0.1 meter less sea level rise that could mean 10 million less people were exposed to related risks.
The report's 91 authors conclude it is still technically possible to limit warming to 1.5 C, but only if countries around the world take much more ambitious action.

Hurricane Michael has arrived, and it's stronger than anyone expected
People look on at a damaged store after Hurricane Michael passed through on October 10 in Panama City, Florida . The death, in an area west of state capital Tallahassee, was the first confirmed since Michael made landfall.
We have been warned: There are now only 12 years left for us to stop global warming in its tracks. Limiting global warming to less than 2ºC will hopefully allow ecosystems and animals to adapt to the gradually rising temperatures.
Former Vice President Al Gore Jr. warned that "time is running out" after the release of a United Nations special report Sunday giving the world 12 years to head off climate calamity by radically transforming "all aspects of society".
The report has predicted that India and other countries with large populations dependent on agriculture and fishery will be highly impacted due to greater sea level rise, higher frequency of droughts and floods, and heatwaves, the environmental think-tank CSE said. To get there, emissions would have to be cut by 45 per cent from 2010 levels by 2030, with further action required by 2050.
Coral reefs would decline by 70 per cent to 90 per cent at 1.5 deg C, whereas virtually all would be lost at 2 deg C.
Individuals and civic groups have a big role to play in pushing governments to tackle climate threats, and are stepping up pressure as recognition of the danger grows, she said. The report also examines pathways available to limit warming to 1.5 °C, what it would take to achieve them and what the consequences could be.
"The next few years are probably the most important in our history", Debra Roberts, co-chair of the IPCC Working Group II, said in a statement marking the report's release. It says that risk warnings in earlier reports underestimated damage already done as well as how quickly we are moving towards disaster.
The president in recent months has slammed wind power as a subsidy-dependent "killing field" for birds, all while rolling back a slew of regulations to boost the coal sector.
