 What breaching 1.5C this year means for curbing climate change - Vox 

Month after record-breaking month, 2023 is on track to be the hottest year measured in human history. 
 
It has been a year of extraordinary drought, deadly rainfall, and searing heat waves. Extreme temperatures even reached underwater. Much of the southern hemisphere basked in summer-like weather through its winter, reaching all the way down to Antarctica. 
 
Particularly notable is that 2023 may mark the first time global average temperatures have risen above a critical line, providing a glimpse into a world where humanity fails to get climate change under control. By the end of the year, some datasets may show the earth’s temperature on average was 1.5 degrees Celsius, 2.7 degrees Fahrenheit, warmer than temperatures before the Industrial Revolution. 
 
That number — 1.5°C — stands out because it was a limit established as part of the 2015 Paris climate agreement. Almost every country in the world agreed that humanity needs to hold warming this century to “well below” 2°C, 3.6°F, above pre-industrial times, ideally limiting the rise to 1.5°C.
