“The weather is crazy” is a phrase that almost all of us have uttered when we go abruptly from hot to cold, or vice versa. The new study scientifically demonstrates how, indeed, the weather is getting crazier and crazier, and that climate change is behind the increasing craziness.  

When we talk about climate change, we are not just referring to it being warmer on average, but to a more general destabilization of the climate system: more heat waves (and cold waves in some cases), more extreme events and greater climate volatility (or increasingly crazy weather). This year has been a good example of the latter, as we have seen rapid swings between spring and winter temperatures. This climate volatility is a process that has not received much attention until now and the published study is among the first to address the influence of climate change on this phenomenon at a global level.

The study shows how climate volatility will increase as a consequence of climate change. The consequences for agriculture can be dramatic, because a few days of early warmth in winter can favor the flowering of many species which, after the return of freezing temperatures a few days later, can destroy that year's crop. These sudden temperature changes also have serious effects on infrastructure, because of the rapid expansion and contraction in response to these temperature changes. Human health can also suffer from these sudden changes in temperature, especially in the most vulnerable groups.
