Say "goodbye" cool summer


14/06/2011

By 2050, the coolest summer in the tropics and parts of the northern hemisphere will be even hotter than the most scorching summer mid-20th century if global warming continues at full speed, according to a new analysis. Tropical regions in Africa, Asia and South America will be able to see "the permanent emergence of unprecedented summer heat" even within the next decades, as reported in the analysis, which was published later this month in the journal "Climatic Change Letters".

Such significant changes in temperature will have a huge impact on human health, food supplies and biodiversity, as researchers have warned. "Large areas of the globe are likely to heat up so quickly that by the middle of this century, even the coolest summers will be hotter than the hottest summer in the last 50 years" - said the chief author of the analysis Noah Diffenbaugh (Noah Diffenbaugh), a professor from Stanford University .
