    The evidence is clear: Our planet is steadily warming

    Today, I decided to post the most recent long-term global, surface temperature data with trends.

    I am including data from NASA GISS, NOAA, UKMET, JMA and Berkeley. Most of the official data go back as far as the mid- or late 1800s. All sources clearly show a distinct, global warming trend.

    In addition, I also included the satellite measured global temperature data from the lower troposphere, which goes back to 1979. Courtesy Remote Sensing Systems.

    NASA GISS

    Monthly global surface temperature anomalies. Clearly, the bulk of monthly warming has taken place after 1990.

    Global temperature trend from 1880 to 1950.

    Global temperature trend from 1950-2016 clearly shows an acceleration of the warming trend.

    Actual long-term surface temperature trend versus the three emissions scenarios. Scenario A is the worst scenario followed by B then C. Based on the data, the globe seems to be running between scenario B and C over recent years.

    Berkeley Earth

    Berkeley Earth shows excellent agreement among several databases, especially since 1950.

    Remote Sensing Systems (Satellite)

    Global satellite measured trend of the lower troposphere since 1979. Anomalies are lower than surface temps due to a later base line and they are measuring the lower troposphere.
