Temperatures are Rising

A World of Agreement: Temperatures are Rising; Global Temperature Anomaly (℃)
This line plot shows yearly temperature anomalies from 1880 to 2018, with respect to the 1951-1980 mean, as recorded by NASA, NOAA, the Japan Meteorological Agency, the Berkeley Earth research group, and the Met Office Hadley Centre (UK). Though there are minor variations from year to year, all five temperature records show peaks and valleys in sync with each other. All show rapid warming in the past few decades, and all show the past decade has been the warmest.

2018 Was the Fourth Warmest Year on Record

2018 was the fourth hottest year on record. Earth has been warming up for decades. The last five years are the hottest five years on record and the last four were all more than 1 degree Celsius, warmer than the 19th Century average.

A warmer climate contributes to melting polar ice and mountain glaciers, rising sea levels, more severe droughts, longer fire seasons.

NASA and NOAA work together to study the temperature from weather stations, ships and buoys in the ocean, and Antarctic research stations.

2018 Was 4th Warmest for Globe

NOAA/NASA’s annual global analysis reveals that 2018 was the 4th warmest for the planet. The report shows record warmth for much of Europe, the Mediterranean, the Middle East, New Zealand and nearby ocean, and parts of the Atlantic and western Pacific. There were 14 billion dollar disasters in the U.S. in 2018 which accounted for $91 billion in direct losses, the 4th largest on record.
