It is instructive to compare these numbers with those characteristic of a set of the years during 1979 — 2012 with no or only one major regional extreme event (in terms of land surface temperature and land precipitation anomalies) in the NH midlatitudes, from late April / early May to late September / early October, as reported yearly since 1993 in the World Meteorological Organization statements on the status of the global climate (see also ref.

Despite the well - recognized interdependence between temperature and precipitation... little attention has been paid to risk analysis of concurrent extreme droughts and heatwaves... We argue that the global warming and the associated increase in extreme temperatures substantially increase the chance of concurrent droughts and heatwaves.

Since increase in temperature leads to an increase in precipitation, global warming creates extreme storms and overall extreme weather.
