    98% of the Earth's Surface is Hotter Now Than at Anytime in the Past 2000 Years

    The 3 graphs below are from an article at the website, carbonbrief.org, titled "The globally coherent rise in temperatures seen since the start of the industrial revolution is unparalleled in at

    least the past 2000 years." This article is a summary from a July 2019 article in the journal, Nature. The graph on the right represents the warmest 51 year periods during the past 2000 years.

    The tiny squares near the bottom represent areas where the earth (2% of it) was warmer in the past than than during the late 20th century. The middle graph represents the Medieval Warming

    Anomaly (MWA) with 40% of the globe experiencing warming at the same time. The Roman Warm Period, the MWA, and the "Little Ice Age" were all primarily regional events with warming or

    cooling not occurring simultaneously over most of the earth's surface.










    The bottom 2 graphs illustrate that the Medieval Warm Anomaly was not so warm compared to the 1999-2008 time frame; most regions were much cooler than the 1961 to 1990
    period.

    This science is consistent with previous studies and indicates that the present warming is not the result of natural (non-human) causes. Natural cycles tend to shift heat from
    one region of the globe to another without greatly affecting the global mean temperature.

    Gray areas indicate no adequate temperature data

    I like it warm. I am so glad we started coming out of the last ice age twenty thousand years ago.

    And we won't stop the next ice age from coming.

    Are you kidding? We're in a solar minimum, we should be cooling right now.

    Lol, who knew they had satellite imaging 2,000 years ago?

    Assuming the conclusion is true, 2000 years isn't that long on the geological scale. Modern humans have inhabited the earth for approximately 200,000 years. And living organisms have inhabited the earth for approximately 3.5 billion years. I'm not saying a 2000 year sample isn't a good sample. The data is worth examining. But "global warming" narratives are often quick to overlook any nuance that may exist whenever the discussion revolves around historical warming trends.
