These proxy records are needed because accurate monitoring of climatic factors extends no farther back than the late 1800s.The graph above reveals what these proxy records along with modern monitoring reveal about the history of Arctic climate change over the past 1,500 years.(Source: NASA GISTEMP)Ima Geo is a visual blog focusing on the intersection of imagery, imagination and Earth.It focuses on spectacular visuals related to the science of our planet, with an emphasis (although not an exclusive one) on the unfolding Anthropocene Epoch.As the report states, the graph illustrates that “the significant post-industrial sea ice decline occurs in concert with significant atmospheric and ocean warming driven by an exponential increase in atmospheric COThis map shows how global temperatures in 2016 differed from those of the early 20th century, before post-industrial-revolution emissions of carbon dioxide began significantly influencing Earth’s climate system.As the map shows, the Arctic is warming more intensely than any other region on Earth.
