If 2014 was considered the warmest year ever recorded, with high temperatures and devastating floods, 2015 is emerging as a candidate to break new records.
The climatic anomalies leave no room for doubt. During March, there were heat records in parts of the western United States and Canada, several regions of East Africa, parts of Scandinavia, northwestern Russia, part of central and southern China, and an area of northeastern Australia. In contrast, central India, southeastern Mauritania, central Mexico and western Canada all experienced colder than normal temperatures.
Furthermore, Finland suffered the third warmest March in the last 116 years, only behind 2007 and 2014 and Australia had the eighth warmest March since there are records in the country (1910).
