On the heels of several consecutive record-breaking "hottest days ever," it has become increasingly clear that there is an urgent need to address human-caused climate change. After all, a recent study published in the scientific journal PNAS revealed that the types of so-called compound drought and heatwaves that humanity is currently experiencing — these are known as CDHW events — are projected to become what co-author Dr. Michael E. Mann labelled a "new abnormal."
By the late 21st century, the PNAS authors contend, approximately one-fifth of the species will endure CDHW events roughly twice a year, each one lasting approximately 25 days, with all of the wildfires and blistering, scorching heat they entail.
