Today is the 58th World Meteorological Day. This year has seen extreme weather events around the world, including blizzards, dust storm, and heat waves.

In the US, the fourth nor'easter in three weeks has slammed the east coast, leading to cancelled schools, flights and clogged roads. In Greece, a dust storm has blown from the Sahara desert and blanketed the country's capital. The dust cast haze over Athens and dampened the sunshine. Other parts of Europe are in the middle of a deadly cold snap. In Britain, London's Heathrow Airport cancelled over a hundred flights. Experts warn the electricity supply in rural areas may be affected. The death toll Europe-wide from the cold spell now surpasses 24.
