A Wild Start for Weather in the New Year

Here we go again. The weather's going to extremes: a snowstorm in Jerusalem, wildfires in Australia, a cold snap in China, a heat wave in Brazil. Based on the first two weeks of the new year, 2013's picking up right where 2012 left off.

As much as 8 inches (20 centimeters) of snow fell on Jerusalem (map) last Thursday, closing roads across the city. It was the biggest winter storm there in 20 years. Scores of trees fell from the weight of the snow, snowball fights broke out in the parks, and Israeli President Shimon Peres was photographed building a snowman outside his residence with help from his bodyguards.

In Australia, where a heat wave was smashing records across the country, the national weather agency added two new colors to its maps to handle the possibility of unprecedented temperatures: deep purple for above 122°F (50°C) and pink for above 125.5°F (52°C). The first eight days of the year were among the warmest on record, with January 7 ranking as Australia's hottest day ever, with an average temperature of 104.6°F (40°C). Some beaches were so hot swimmers couldn't walk to the water without burning their feet on the sand.

Elsewhere around the globe, the weather has been equally extreme. While much of the eastern U.S. and northern Europe basked in springlike weather, Tokyo (map) saw 3 inches (7.6 centimeters) of snow fall on the city this weekend, nearly half of its typical total for a full year.

In China, the average temperature fell to 25°F (-4°C) in early January, the lowest in nearly three decades. More than a thousand ships in China's Laizhou Bay (map) have been frozen into the ice.

At the same time, a heat wave and drought in northeast Brazil prompted officials to consider rationing electricity for the first time in a decade, and the temperature in Rio de Janeiro (map) reached a record 109.8°F (43°C).
