Climate upset

El Niño is set to disrupt the world’s weather again. This year’s
reversal of Pacific equatorial currents has raised sea surface temperatures near
the shores of South America by 5 °C. The US National Oceanic and Atmospheric
Administration says this is the highest since the huge El Niño of
1982-83, which disrupted climate around the world, triggering drought and
massive bush fires in Australia and Indonesia.
