|March 2019, NASA GISS|
GISS found March to be the 3rd warmest March in their records, and the 6th warmest of any month since their records began in 1880. The land-only anomaly of 1.39°C relative to 1951-1980 was the 2nd highest for March, and the 4th highest of all month.
Year-to-date 2019 is +0.12°C compared to last-year-to-date.
The land-only 30-year trend is 0.24°C/decade, meaning the warming over the last three decades is 0.73°C (1.32°F). That's over 0.4°F each decade.
The Japanese Meteorological Association also found the globe to be the 3rd warmest March (since 1890), and the 12th warmest of all months.
