Researchers Emily Yeh and Brian Catlos are recognized for prior career achievements and exceptional promise

Two University of Colorado Boulder scholars have been named , recognizing not only their prior career achievements but also their exceptional promise.

Emily Yeh, a professor of geography and College of Arts and Sciences professor of distinction, and Brian Catlos, a professor of religious studies and director of the , are among a group of scholars, scientists, artists and writers representing 52 scholarly disciplines and artistic fields, who 鈥渁re meeting (humanity鈥檚 existential) challenges head-on and generating new possibilities and pathways across the broader culture as they do so,鈥 noted Edward Hirsch, award-winning poet and president of the John Simon Guggenheim Memorial Foundation, in announcing the fellowships.听

The monetary award that accompanies the Guggenheim recognition will support Yeh in writing a book about global geographies of weather modification in the context of climate change adaptation and growing discussions about geoengineering.

t鈥檚 going to be an expansion of my previous research on cloud seeding,鈥 Yeh explains. 鈥淐loud seeding as a practice has been around since the 1950s, but a lot of people don鈥檛 really know that it happens.

鈥淚 think it鈥檚 really important right now for two reasons: One is climate change and drought, with cloud seeding being seen as a form of climate adaptation which is being adopted by countries around the world. The second is the growing interest in stratospheric aerosol injection, a form of geoengineering, for climate mitigation, and the public conflation of this with cloud seeding.鈥

Yeh, who has conducted a significant amount of her scholarly research in China and Tibet, first became interested in cloud seeding through a Chinese project called Sky River, or Tian He: 鈥淭here were a whole bunch of reports about how the Chinese government was going to move water vapor from the Himalayas and channel it over the Tibetan Plateau to the north. I started following that issue, and through that realized that even though that idea of channeling water vapor itself isn鈥檛 a reality, some of the ideas behind it are very revealing of certain imaginations of nature that also underpin the Chinese state鈥檚 discourse of 鈥榚cological civilization.鈥欌

She says that in some of the Tibetan villages she鈥檚 visited on the border of Sichuan and Gansu provinces, few safety precautions accompany cloud seeding measures, so that rockets can fall without warning on herders鈥 pastures. They experience cloud seeding as a form of injustice, she explains. At the same time, experiences raise questions about what cloud seeding operations claim versus what effects they have. 鈥淥verclaiming of results is leading to conspiracy theories, like the idea that recent flooding in the United Arab Emirates was caused by cloud seeding rather than climate change,鈥 Yeh says.

Boulder, as a national and international center of cloud seeding research and technology, is an ideal place to study not only cloud seeding in the context of drought in the American west, Yeh notes, but also institutional and political economic contexts for cloud seeding research and practice globally.

Reassessing history

For Catlos, the Guggenheim recognition will support him in writing An Age of Convergence: Christians, Muslims and Jews in the Pre-Modern Mediterranean, a culmination of his scholarship to date showing when, how and why members of these three faith communities鈥攚hich hail from Africa, the Middle East and Europe鈥攖ogether laid the foundations of Western modernity.

鈥淭raditionally, the way we鈥檝e conceived of the West has been this sort of western European, essentially Christian culture that coalesced in the Middle Ages and led to Anglo-European culture and society today,鈥 Catlos explains. 鈥淭hat鈥檚 based on a lot of assumptions and perspectives that are rooted in 19th century ideas of how society works鈥攕ome racist, some colonial, some rooted in notions that the fundamental building block of history is the nation.

鈥淭hese are ideas that became popular in the 19th century, a great age of nationalism, racism and colonialization as well. When we look at data and pull back from presumptions and prejudices, what we see is that what became the modern West鈥攚estern Anglo-European culture and society鈥攅merged out of a much broader historical background.鈥

In 650 CE, as Islam began expanding from the area west of the Indus River to the Atlantic Ocean and all the way around the Mediterranean, a common telling of the history of that time holds that the area was uniformly Abrahamic in terms of faith and culture. 鈥淭here鈥檚 this idea that the three religious cultures were divided and oppositional鈥攁nd they were to certain degree鈥攂ut they also were deeply enmeshed and influenced each other both through polemic and also through collaboration and shared knowledge.鈥

Another prevalent myth, Catlos says, is that there were distinct spheres: a Christian sphere, a Muslim sphere, 鈥渕aybe a Latin-Christian sphere, a Christian and Byzantine sphere, a Christian and Muslim sphere, and they were somehow coherent, homogenous social, cultural and political entities in opposition with each other,鈥 Catlos says.

鈥淭hat鈥檚 not really the case. There were lots and lots of Muslims and Jews living in Christian lands and vice versa. The division was not really there except in certain contexts.

鈥淭hink about crusade and jihad, about Christianity and Islam, about this clash of civilizations. If we look at the political and economic history of the pre-modern period in the larger Mediterranean world, we see that both of these spheres are broken into a whole range of different kingdoms, city states, etc. that in fact are in competition with each other, for number of reasons, not the least of which is geography and how it impacted the way that resources appear and are accessed.鈥

Rather than a united front of Muslim states vs. Christian states, Catlos says, 鈥渨e see competition between Muslim states with each other, Christian states with each other, Muslims and Christian principalities seeking alliances with each other against rivals of their own faith. Much of the history of the West that we are taught is distorted and needs to be reassessed.鈥
