A controversial new study claims we may breach the 2 degrees Celsius (3.6 degrees Fahrenheit) climate change increase threshold by the late 2020s — almost two decades earlier than current projections.
The study, published Feb. 5 in the journal Nature Climate Change, claims global surface temperatures had increased by 1.7 C (3 F) above pre-industrial averages by the year 2020.
However, other scientists have questioned the findings, saying that there are major flaws in the work.
The IPCC keeps rejecting “hot models” that show more warming than CO2 has caused in the past.
Those models keep coming up as accurate often enough that it’s now referred to as the “hot model problem”.
