NOAA just released their global land+sea temperature anomaly for March 2020: +1.16°C above the 20th century average (1901-2000). That makes it the second warmest hottest March in their records, after only 2016, and the 4th warmest (most anomalous) of any month beginning in 1880.
This is the 4th consecutive month with an anomaly above 1.0°C. It brings the total amount of warming (slope*interval) to 1.05°C, rising at 0.025°C/yr or 0.25°C/decade.
But a quadratic model gives a total warming of 1.15°C, with an acceleration of +0.016°C/decade2.
