Reducing the emissions of carbon dioxide and other greenhouse gases is the only realistic solution to the climate crisis. However, unlike some other forms of pollution, carbon dioxide is invisible to the human eye. This makes it harder to communicate the challenge of global warming to the public.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These&nbsp;visualisations&nbsp;by NASA \u2013 the&nbsp;US National Aeronautics and Space Administration&nbsp;\u2013 show CO<sub>2<\/sub> emissions build up in the atmosphere over the course of a year.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Cumulative CO2 emissions in 2021\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/ZJd8rKq8PsM?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The videos show emissions from a range of sources: human-caused burning of fossil fuels (yellow); human-caused burning biomass (red); land ecosystems (green) and the ocean (blue).
