An intensification of heat is forecast from the weekend onwards which could lead to some record high temperatures for September and October. While there are precedents for heat of a similar order of magnitude in other early autumns, there has been a significant concentration in recent years.  

We are witnessing a transition in which what was exceptional until not so long ago is becoming commonplace. This is the new climatic reality. The number of hot days is increasing, with more and more of them occurring in spring and autumn, which has the effect of lengthening the summer weather. In the past there have always been hot spells in both spring and autumn, but not with the frequency and magnitude that we are experiencing today. 

We need to adapt quickly to this new climate framework. High temperatures have a direct and negative impact on health, in addition to the dangers posed by extreme weather events, which we see are becoming more intense. We are vulnerable to them and need to take protective measures, starting with prevention. Beyond this, to avoid the worst-case scenarios of climate projections, we must urgently reduce emissions of greenhouse gases into the atmosphere from the burning of fossil fuels. This must be done decisively and on a global scale, which means profoundly changing the unsustainable model of society we have been creating. It is a difficult challenge, but not an impossible one.
