In this year of extreme weather events — from devastating West Coast wildfires to tropical Atlantic storms that have exhausted the alphabet — scientists and members of the public are asking when these extreme events can be scientifically linked to climate change.

What Fuels the Beating Heart? Study Reveals Nutrients Used by Normal and Failing Hearts
A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has produced a detailed picture of fuel and nutrient use by the human heart. The study, published this week in Science, was the first of its kind, involving the simultaneous sampling of blood from different parts of the circulatory system in dozens of human participants, in order to record the levels of related molecules going into
Unprecedented Energy Use Since 1950 has Transformed Humanity's Geologic Footprint
A new study coordinated by CU Boulder makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as the Anthropocene. Distinct physical, chemical and biological changes to Earth’s rock layers began around the year 1950, the research found.
Led by Jaia Syvitski, CU Boulder professor emerita and former director of the Institute of Alpine Arctic Research (INSTAAR), the paper, published today in Nature Communications Earth and Environment, documents the natural drivers of environmental change throughout the past 11,700 years—known as the Holocene Epoch—and the dramatic human-caused shifts since 1950. Such planetary-wide changes have altered oceans, rivers, lakes, coastlines, vegetation, soils, chemistry and climate.
“This is the first time that scientists have documented humanity’s geological footprint on such a comprehensive scale in a single publication” said Syvitski, former executive director of the Community Surface Dynamics Modeling System, a diverse community of international experts from who study the interactions between the Earth’s surface, water and atmosphere.
