Climate Change May Prompt Rise in Skin Cancers

For decades, scientists have known that the effects of global climate change could have a potentially devastating impact across the globe, but new data suggests that it may also detrimentally affect human health.  James G. Anderson, from Harvard University (Massachusetts, USA), and colleagues warn of a newly-discovered connection between climate change and depletion of the ozone layer over the US that could allow more damaging ultraviolet (UV) radiation to reach the Earth's surface, leading to increased incidence of skin cancer. In the system described by the team, water vapor injected into the stratosphere by powerful thunderstorms converts stable forms of chlorine and bromine into free radicals capable of transforming ozone molecules into oxygen. Recent studies have suggested that the number and intensity of such storms are linked to climate changes, which could in turn lead to increased ozone loss and greater levels of harmful UV radiation reaching the Earth's surface, and potentially higher rates of skin cancer.  The study authors urge that: “Were the intensity and frequency of convective injection to increase as a result of climate [change]   … increased risk of ozone loss and associated increases in UV dosage would follow.”

30. Look on the Bright Side of Life
Older adults with a bright outlook on the future live longer than those who have a dimmer view. A nine-year long study conducted by Netherlands researchers found that men and women with the highest levels of optimism at the start of the study had the lowest death rates than those in the most pessimistic group. Considering all factors in-total, the risk of death was 29% lower among highly optimistic men and women. In addition, the most optimistic study participants experienced 77% less likelihood of dying of a heart attack, stroke, or other cardiovascular cause (as compared to the most pessimistic group).
