(2020). The pace of global warming does seem to be undergoing a slowdown that is likely temporary, but it has by no means "stopped." Scientists attribute the global warming trend observed since the mid-20 th century to the human expansion of the "greenhouse effect" 1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Earth’s water is stored in ice and snow, lakes and rivers, the atmosphere and the ocean. doi: https://doi.org/10.5067/MEASURES/CRYOSPHERE/nsidc-0530.001. In the 1860s, physicist John Tyndall recognized Earth's natural greenhouse effect and suggested that slight changes in the atmospheric composition could bring about climatic variations. Significant changes are occurring on Earth, including increasing air and ocean temperatures, widespread melting of snow and ice, and rising sea levels. Many schools, organizations, government bodies, etc. In 1856, Eunice Foote discovered that blanket, showing that carbon dioxide and water vapor in Earth's atmosphere trap escaping infrared (heat) radiation. President Donald Trump mocked concerns about global warming, saying that oceans would rise just “[o]ne-eighth of an inch within the next 250 years.” He suggested something in the atmosphere must be acting like an insulating blanket. The polar bear standing on a chunk of shrinking ice, apparently stranded, has become a familiar image, a symbol of the devastating effects of climate change. The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950.
