NASA Confirms That 2023 was the Hottest Summer on Record

Yesterday, NASA’s Goddard Institute of Space Studies (GISS) announced that the summer of 2003 was the hottest on record. This year saw a massive heat wave that swept across much of the world and was felt in South America, Japan, Europe, and the U.S. This exacerbated deadly wildfires in Canada and Hawaii (predominantly on the island of Maui) and are likely to have contributed to severe rainfall in Italy, Greece, and Central Europe. This is the latest in a string of record-setting summers that are the direct result of anthropogenic climate change.

2020 Ties for the Hottest Year on Record

According to multiple sources – which includes NASA, the NOAA, the Berkeley Earth research group, and the Met Office Hadley Centre (UK) – global temperatures over the past few years have been some of the hottest on record. This is the direct result of anthropogenic factors like overpopulation, urbanization, deforestation, and increased greenhouse gas emissions (like carbon dioxide and methane).

According to a recent press release from NASA, in terms of global temperatures, 2020 was the hottest year on record – effectively tying it with 2016 (the previous record-holder). The release includes a dramatic video that illustrates average temperature increases since 1880 and the ecological crises that have taken place just this past year. This is yet another warning of how human agency is impacting the very systems we depend upon for our continued survival.

There are a handful of major science institutions around the world that keep track of the Earth’s temperature. They all clearly show that the world’s temperature has risen in the past few decades. One of those institutions is NASA.
