But climate also changes locally, and many of these local changes are due to other human causes such as…

In the past week I’ve run across several sources of maps related to various aspects of climate that you might find useful. NOAA Global Vegetation Health Maps show the conditions of vegetation around the world on zoomable maps. Data are based on satellite scans from space. https://www.climate.gov/maps-data/dataset/global-vegetation-health-images for information or go directly to the map browser at https://www.star.nesdis.noaa.gov/smcd/emb/vci/VH/vh_browseVH.php.…

According to New Atlas, the Chinese satellite TanSat has provided the first global maps of carbon dioxide. In the article, it shows maps from two months, April and July 2017. This satellite view will allow scientists to study changes in carbon dioxide across the earth depending on the season as well as highlight local maximums…
