By 2050, primary consumers are forecasted to shift their seasonal timing by more than twice as much as other species, potentially disrupting relationships between plants and animals.
A study found that 34% of hospitals in low- and middle-income countries lacked continuous running water, compromising patient care. Hospitals without running water often rely on trucked-in or rainwater, which can be contaminated and unsanitary.
A Harvard University study forecasts that boreal forests in far-northern latitudes may act as a climate refuge for black spruce trees due to higher rainfall. The research also suggests that the region's growing season will expand by 3 weeks, but drought stress could overwhelm trees south of the 49th parallel.
