The American Geophysical Union (AGU) is a professional organization dedicated to advancing the understanding of Earth and space sciences. Founded in 1919, it brings together scientists from various disciplines, including geology, meteorology, and oceanography, to share research and collaborate on scientific issues. AGU publishes numerous scientific journals and organizes conferences to facilitate communication among researchers. AGU also plays a significant role in promoting science education and public engagement. It advocates for policies that support scientific research and works to increase awareness of the importance of Earth and space sciences in addressing global challenges, such as climate change and natural disasters.
