" over the last five years, several independent assessments have placed the sensitivity at about 1°C (1.8°F)"


We've already been above 1 degree, and we're just over 40% of the way to doubling pre-industrial levels. Feb.'16 was 1.51 degrees above pre-industrial.


2016 Temperatures Measure 1.2 Degrees C Above Pre-Industrial Levels

Nov 14, 2016 - This year is on track to become the hottest year on record, with global temperatures measuring 1.2 degrees Celsius (2.2 F) above pre-industrial

During 2018, 11 of 12 monthly global land and ocean temperature departures from average ranked among the five warmest for their respective months, giving way to the fourth warmest year in NOAA's 139-year record. The years 2015–2017 each had a global temperature departure from average that was more than 1.0°C (1.8°F) above the 1880–1900 average, which is a period that is commonly used to represent the pre-industrial conditions. However, 2018 was just shy of reaching the 1.0°C (1.8°F) mark at 0.97°C (1.75°F).The year began with a La Niña episode present across the tropical Pacific Ocean, transitioning to ENSO-neutral by April 2018.
