Analysis of historic data about the mysterious El Niño, which periodically unleashes such devastating weather events, reveals that it has a bad local side, an even worse global side − and scientists warn that another storm may be brewing

Cities Twin Heat Problems Face Relief

Cities Twin Heat Problems Face Relief

Climate change aside, cities tend to be warmer than the surrounding ciuntryside. Now researchers in the US have found ways that may lessen the effects of both problems. Even without global warming, atmospheric temperatures are likely to rise later in the century: the expansion of the cities will see to that.
