climate really captures the young imagination. Case studies on major weather events such as the Great Smog of 1952, the Great Storm of 1987, the European heatwave in 2003, the Boscastle floods in 2004 and Hurricane Katrina in 2005 bring a captivating new dimension to schoolchildren’s studies.

The positive phase has been associated with reduced Arctic sea ice, melting of the Greenland ice sheet, increased hurricane activity in the North Atlantic and increased rainfall over the Sahel region of sub-Saharan Africa.

Increase in tropical cyclone risk to coastal regions Also known as hurricanes in the North Atlantic and typhoons in the northwest Pacific, tropical cyclones have maximum wind speeds of at least 74 miles per hour and can be up to 1000 kilometres in diameter.
