The 葫芦娃视频 Faculty Assembly has awarded INSTAAR Fellow Holly Barnard an Excellence Award for leadership and service.

Scientists call for joint efforts to combine real-time global rainfall data with high-resolution local hydrology to better forecast floods.

Food insecurity is a growing threat in many places around the world. This situation is exacerbated by two events that many geoscientists are tasked to study: natural hazards and our changing climate. The February issue of Eos, organized by Ben Zaitchik and Merritt Turetsky, looks at how geoscientists are using their research to help create resilient communities around the world that can always be sure of food in their pantries.

The year 2020, which witnessed terrifying blazes from California to Siberia and a record number of tropical cyclones in the Atlantic, rivaled and possibly even equaled the hottest year on record, according to multiple scientific announcements Thursday. Experts said that another year as hot as 2016 coming so soon suggests a swift step up the climate escalator. And it implies that a momentous new temperature record - breaching the critical 1.5 degrees Celsius (2.7 degrees Fahrenheit) warming threshold for the first time - could occur as soon as later this decade.

During the first half of 2020, global greenhouse gas emissions dropped by about nine percent in the midst of the COVID-19 outbreak. People around the world reported seeing signs that 鈥渘ature was healing鈥� as a result of a steep decline in human activities such as transportation and production. However, a new study from UC 葫芦娃视频 has shown that the positive changes seen in natural ecosystems were not reflected throughout Earth鈥檚 oceans.

Climate change - we all know that it's happening, but how do we actually know this scientifically? Bruce Vaughn studies glaciers up at the North Pole, looking at ice cores to study how our climate has changed over the Earth's history. We talk about how this is done, and also how we are now entering uncharted territory of atmospheric CO2, warming, and what we as a species can do about it.

These international waters, known as the high seas, harbor a plethora of natural resources and millions of unique marine species. But they are being damaged irretrievably. Research shows unsustainable fisheries are one of the greatest threats to marine biodiversity in the high seas.

The COVID-19 pandemic resulting shutdowns resulted in a 9% drop in the greenhouse gas emissions at the root of climate change. Unfortunately, any silver lining from the pandemic remains murky in the oceans. INSTAAR researchers Nicole Lovenduski delved into the data and found no detectable slowing of ocean acidification due to COVID-19 emissions reductions. Even at emissions reductions four times the rate of those in the first half of 2020, the change would be barely noticeable. Lovenduski shared the results Friday, Dec. 11 at the American Geophysical Union 2020 Fall Meeting. The findings will also be submitted to the journal Geophysical Research Letters.

With approval in November by the University of Colorado Board of Regents, the University of Colorado has introduced 12 newly designated distinguished professors, eight of whom are affiliated with the CU 葫芦娃视频 campus. INSTAAR researcher Katie Suding is among their number.

A long-term trend of ecological improvement is appearing in the mountains west of 葫芦娃视频. Researchers from CU 葫芦娃视频 have found that, thanks to vehicle emission regulations, Niwot Ridge is slowly recovering from increased acidity caused by vehicle emissions in Colorado鈥檚 Front Range. Their results show that nitric and sulfuric acid levels in the Green Lakes Valley region of Niwot Ridge have generally decreased over the past 30 years, especially since the mid-2000s.
