Heat waves tied to flare-ups of digestive illness

Reuters: Flare-ups of inflammatory bowel disease and "stomach bugs" may be more common during and immediately after heat waves, a new study suggests. Swiss researchers looked at five years of records from one hospital and found more admissions related to inflammatory bowel disease (IBD) during long stretches of hot days. Hospitalizations for so-called infectious gastroenteritis, marked by vomiting and watery diarrhea, also increased, lagging behind IBD admissions by about a week. The study "shows...
More Frequent Heat Waves by 2020 Almost Certain

Climate News Network: Stand by for extreme weather. Prepare for heat waves on a scale that was once unprecedented. For once, there are no "ifs' in the forecast, no caveats about modeling business-as-usual-scenarios rather than dramatic reductions of emissions for near-term warming Even if governments abandon fossil fuels everywhere, immediately, and invest only in green energy, there will be new record temperatures. The greenhouse gas emissions of the last few decades now mean that regions of the planet subjected to...

Death tolls from summer heat waves are hazy
2013-08-17 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Wall Street Journal: Hot weather can be deadly, but a summer's full toll often isn't known until after fall has arrived. When a heat wave strikesas it has this summer in the U.S., Europe and Chinadeath rates rise. But heat's role usually isn't readily apparent. Instead, its victims die of underlying conditions, usually of the heart or lungs, that needed the extra ingredient of heat to become fatal. Moreover, those who succumb to heat often die alone and aren't discovered until after their bodies have cooled. So heat's...
Rise in Extreme Heat Waves Already Locked in for Next 30 Years

Nature World: The amount of global land affected by extreme heat waves classified as three-sigma events is set to double by 2020 and quadruple by 2040 regardless of changes in the amount of carbon dioxide released into the atmosphere, a study published in Environmental Research Letters reports. Heat waves classified as three-sigma events -- a reference to a rise in temperatures of three standard deviations above the norm -- include the one that hit Australia in 2009 and more recently the one that took place...
Heat waves make cities swelter synergistically

Scientific American: No wonder its gonna be a hot time in the old town tonight. Cities can be anywhere from 2 to 20 degrees Fahrenheit hotter than nearby countryside, due to whats known as the "urban heat island" effect. But when heat waves roll through, they interact synergistically with the urban heat islandboosting temperatures even higher than you might expect. Researchers used a June 2008 heat wave in Baltimore as a case study. They compared temperatures downtown to those near the Baltimore/Washington International...
