UArizona experts available to discuss extreme heat
TUCSON, Ariz. — University of Arizona researchers from a variety of disciplines are available to speak about the national and global impact of extreme heat.
The Global Meteorological Organization on Wednesday announced that "global temperatures are likely to surge to record levels" between 2023 and 2027, largely due to greenhouse gas emissions and a naturally occurring El Niño climate pattern in the coming months.
The following UArizona climate scientists and climate policy experts are available to speak about increasingly extreme heat.
Theresa Crimmins is a research professor in the School of Natural Resources and the Environment in the College of Agriculture and Life Sciences. She is the director of the USA National Phenology Network, based at UArizona. Crimmins' team, in partnership with scientists around the world, track when plants and animals undergo seasonal life cycle events throughout the growing season, then use those observations to better understand how the timing of seasonal events like spring bud burst and bloom and animal migration are changing, which can have major implications for human health, agriculture, tourism, wildfires and more.
