The year was extraordinary, featuring the hottest year on record equalling 2005, the most extreme winter Arctic atmospheric circulation on record, the warmest and driest winter on record for North America-Canada, the lowest volume of Arctic sea ice on record and 3rd lowest in extent, a record melting in Greenland, the second most extreme shift from El Niño to La Niña, the second worst coral bleaching year, the wettest year over land, the Amazon rainforest experienced its 2nd 100-year drought in 5 years and, it must be said, we had the lowest global tropical cyclone activity on record. Here’s the precipitation graph: Continue reading Climate clippings 33→
