2019 Was Second-Hottest Year On Record, Capping Off Hottest Decade

Since 1880, temperature records show a consistent warming trend. NASA and NOAA studies reveal that 2019 was one of the hottest years, with ocean heat content at its highest. This warming trend is attributed to human activities, primarily due to increased greenhouse gases. Every decade since the 1960s has been warmer than the previous one, indicating a persistent climate change pattern.

What year was the only one hotter than 2019 according to NOAA?

• 2018

• 2017

• 2016

• 2015

What is the significance of ocean heat content reaching its highest level in 2019?
