Over the past 130 years, average temperatures over all land and ocean surfaces have warmed by roughly 1.53°F.
Earth’s temperatures have always been in flux, but only recently has warming change been so rapid. Ancient glaciers anchored on land are now melting, which is causing global ocean levels to rise and coastal lands to sink.
As eloquently stated by the American Geophysical Union, Earth’s citizens require a solid understanding of the Earth sciences to comprehend and effectively address many of the issues confronting society today, such as climate change, natural hazards, environmental changes, and resource availability.
Every autumn, the full moon takes on an orange color due to its closeness to the horizon. But this year’s “Harvest Moon” will be even more special.
