Reacción a "Reactions to the heat wave affecting Spain these days"

The current heat wave that is dramatically affecting Spain is a preview of the climate that awaits us as a consequence of the unstoppable increase in greenhouse gas concentrations in the atmosphere due mainly to the widespread - and still growing - use of fossil fuels (coal, oil derivatives and natural gas).  

Estimates for the evolution of heat waves made with the help of climate models show increasingly frequent, intense and long heat waves, depending on the degree of increase of these three characteristics, depending on the path followed by global greenhouse gas emissions. 

At present, the attribution of an extraordinary event - such as the current heat wave - to current anthropogenic climate change can only be made in terms of a change in the probability of its occurrence and after numerical simulations and comparisons with real observations.  

Surely, the studies that will be carried out when the heat wave is over and all the data are analyzed will indicate that, with the current perturbed climate, the probability of occurrence of this event has increased with respect to the probability of occurrence in a hypothetical climate not perturbed by human action. More seriously, the probability of similar events will continue to increase if the causes of current climate change, i.e., increasing greenhouse gas emissions, are not controlled.
