Food Crisis Due to Ukraine War Calls for Demand-Side Action
The global food system is impacted by the war in Ukraine, adding to the direct humanitarian and security crisis caused by the Russian aggression. Ukraine and Russia are major producers of grains and fertilizers. Experts say that focusing on short-term supply-side solutions is not the way to go. Rather, changes to the demand side of the global food system can lead to both a more resilient and more sustainable global food system.

Demographics Alone Do Not Explain COVID-19 Mortality Rates -- Place Matters, Too
Many Americans became amateur data scientists during the pandemic, tracking local rates of infection or vaccination to help them decide what activities may or may not be safe. Researchers examined this collected county-level data, and found that different demographic groups are vulnerable in different ways—often depending on their geographic location.

Global COVID-19 Deaths May Be 3 Times Higher Than Recorded
Today in The Lancet researchers say excess deaths data indicate that the global death toll from the COVID-19 pandemic may be more than three times higher than officially record. Excess mortality was calculated as observed mortality minus expected mortality. The authors excluded weekly death tolls during times of anomalies, such as heat waves, from their calculations.

Accelerated Impact of Climate Change on Human Wellbeing, Nature
Increased heatwaves, droughts and floods are already exceeding plants’ and animals’ tolerance thresholds, driving mass mortalities in species such as trees and corals. These weather extremes are occurring simultaneously, causing cascading impacts that are increasingly difficult to manage. They have exposed millions of people to acute food and water insecurity.

COVID Vaccines Offer Lasting Protection against Reinfection: Studies
Two new studies suggest good, durable protection of COVID-19 vaccines against recurrent infection. NEJM editor-in-chief said that COVID-19 survivors can still benefit from subsequent vaccination, although the ideal time to vaccinate is yet unknown: “There is an advantage, and although the absolute risk difference may be small, it’s real. Also, there doesn’t appear to be a safety issue with getting boosted.”

How a Two-century Megadrought Gap Set Up the West for Its Water and Climate Crisis
Since the turn of the 21st century, researchers probing evidence locked in tree rings and other clues to past climate conditions have been building an increasingly unnerving picture of southwestern North America as prone to deep, prolonged droughts. Megadrought is the emerging term for the worst of these extreme dry spells — those lasting two decades or more.

Speed and Surprises: Decline and Recovery of Global Electricity Use in COVID’s First Seven Months
The unprecedented plunge in electricity use around the world at the beginning of the global pandemic was tied to shut-down policies and other factors. Surprisingly, the recovery to pre-COVID levels was quite fast and not linked to those same factors.

U.S. Needs New Drought Assessment Framework as Droughts Become More Severe and Unpredictable
Droughts in the United States are becoming more intense and unpredictable, and the nation needs to develop a new drought assessment framework to better understand and address them. A new framework should be developed which distinguishes between short-term operational needs, such as drought monitoring and emergency response, and long-term planning for water management, infrastructure, and climate adaptation.
