IPCC releases landmark report emphasizing the existence of and threat posed by human-driven climate change

The United Nation’s Intergovernmental Panel on Climate Change (IPCC) has published its most dire assessment on climate change ever as part of its Sixth Assessment Report (AR6). The report, Climate Change 2021: The Physical Science Basis, was contributed by Working Group 1, a group of 234 authors, including PCC Executive Board Member Kyle Armour (ATM S/OCEAN) as a Contributing Author, and cites over 14,000 scientific papers.

The Arctic Ocean's "Last Ice Area" may be vulnerable to climate change

The Arctic Ocean's "Last Ice Area" may be at risk according to a recent UW study led by scientists from the Polar Science Center at the Applied Physics Lab (APL), including Kristin Laidre (SAFS) and Mike Steele (APL). The "Last Ice Area," located north of Greenland and the Canadian Arctic Archipelago, is so named due to its potential to sustain the populations of ice-dependent species when the surrounding region is rendered uninhabitable, but this research asserts that some parts of the area are already experiencing a decline in summer sea ice. The team's research focused on ice in the Wandel Sea during the August of 2020, where sea ice has historically been thick and long-lasting. However, satellite images showed that the region experienced a record low 50% ice coverage on August 14, 2020. Using satellite data and sea ice models, the team found that 80% of the record low ice coverage could be accounted for due to weather-related factors including disruptive winds, but the remaining 20% was a result of the thinning of sea ice as a result of global warming. Critically, this melting occurred in spite of the presence of thick, aged sea ice, not without it, dispelling hopes that the reformation of older, thicker ice would significantly mediate the cycle of warming oceans leading to thinner ice. This data from the Wandel Sea cannot be immediately generalized to the entire "Last Ice Area," but if these trends are reflected across the region, the many creatures that depend on the presence of ice, including polar bears and walrus, will be greatly at risk.

The weakening of Pine Island's ice shelf is increasing the speed of a critical Antarctic glacier

Recent research led by Ian Joughin of the UW's Applied Physics Laboratory has shown that the ice shelf responsible for holding back one of the fastest-moving Antarctic glaciers is imploding, the culmination of decades of warming and stress. The ice shelf supports the Pine Island Glacier, which contains around 180 trillion tons of ice, an amount that could lead to 1.6 feet of sea level rise if it were allowed to completely flow into the ocean. The glacier's advance is already responsible for raising the global sea level by one-sixth of a millimeter per year, a rate equivalent to two-thirds of an inch per century, and one that is expected to increase in coming years. In the past, the glacier's acceleration was driven by warm ocean currents melting the undersides of the ice shelves supporting it, but Joughin and his team have noticed a different process in recent years, which is not directly caused by ocean warming. Instead, studying data from 2017-2020, the team observed that the glacier's previous acceleration had caused the ice shelf to rip itself apart. This phenomenon was responsible for the majority of the glacier's acceleration in recent years. However, the future of Pine Island is still unclear. Currently, the glacier's acceleration is not catastrophic, but if the Pine Island Ice Shelf is lost in upcoming decades, as seems possible, the rapid changes could lead to drastic, irreversible consequences felt all across the globe.

Can Communicating the Benefits of Novel Ecosystem Restoration Techniques Promote Climate Change Literacy and Action?

Learning about how restoration projects can benefit their communities can inspire people to take more than just the usual, low-effort actions meant to address climate change. Read about my online workshop held in fulfillment of the UW PCC Graduate Certificate in Climate Science. Written by James Lee I’m from a place in the San Francisco Bay Area where ecosystem restoration is talked about a lot.

South Pole and East Antarctica were warmer during the last ice age than previously thought, new studies show

Two new research papers, co-authored by PCC participants, show that temperatures in East Antarctica and other locations in the South Pole during the last ice age were several degrees warmer than previously thought. Research previously asserted that during the last ice age temperatures in Antarctica were an average of 9° C below modern values. However, that data did not match estimates from climate models and lacked calibration. The new research resolves these issues. Papers co-authored by TJ Fudge (UW ESS),  Eric Steig (UW ESS and current PCC Governing Board member), Emma Kahle a recent graduate of UW ESS, and Edwin Waddington (UW ESS), along with many other national and international partners used data from borehole thermometry, snowpack accumulation, and the South Pole Ice Core project to show that temperatures across Antarctica were 4-6° C cooler than today. Both studies reconcile observed data with climate model estimations, support the legitimacy of using models to reproduce climatic shifts, and help explain how the Antarctic responds to large-scale changes in climate.

Lessons Learned: How Can We Connect Middle School Students to Climate Change and Ocean Acidification?

A collaboration between UW students and DNR using local nearshore ecosystems as examples to center a climate change curriculum. A capstone in fulfillment of the UW PCC Graduate Certificate in Climate Science. Written by: Amanda Arnold, Katie Byrnes, and Lizzy Matteri Climate change is so vast and complex, riddled with intricate interactions, making  teaching it to young students daunting. Additionally, while many middle school teachers have training in biology and want to incorporate climate change and biological responses to climate change in their teaching, they often lack formal coursework in climate change.

The local economic impact of the “fracking boom” in Ohio

An ACORN Project completed by University of Washington graduate students Logan Arnold (Master’s Student, Quantitative Ecology and Resource Management) and Tyler Cox (PhD Student, Atmospheric Sciences) in collaboration with the Ohio River Valley Institute Technological advancements in the last decade have allowed companies to profit off of the shale gas reserves underlying portions of the U.S. – the so-called “Fracking Boom.” Ohio, in particular, has seen an enormous surge in natural gas production since 2013.
