When weather extremes meet climate change: how do scientists attribute single events to climate change?

When weather extremes meet climate change: how do scientists attribute single events to climate change?

One of the main new points of the IPCC reports AR6 with respect to the previous ones is the increased confidence that global climate change induced by anthropogenic emissions is critically affecting the dynamics of weather extremes. For summer, and specifically over Europe, the AR6 report states that we are already observing prolonged periods of extremely warm conditions with increased droughts bo ...[Read More]

From the eyes of tropical cyclones to flooded strands : how climatologists use weather events to make climate predictions?

From the eyes of tropical cyclones to flooded strands : how climatologists use weather events to make climate predictions?

While extreme events are meteorological in nature, climatologists collect them to draw conclusions about the state of the present climate and to get clues how they possibly change in the future. Thus, climate and weather find common ground. If we consider an event alone, we are not studying the climate, we are in the field of meteorology, the goal of climatologists is therefore to put extreme even ...[Read More]

Three reasons why Forest-Fires worsen with climate change

Three reasons why Forest-Fires worsen with climate change

The brand-new IPCC AR6 report clearly states that “Unless there are immediate, rapid and massive reductions in greenhouse gas emissions, limiting warming to around 1.5°C, or even 2°C, will be out of reach”. Although as human beings we do not perceive changes in global Earth average temperatures as a threat to our lives, the IPCC report also states that extreme weather events will worsen; actually ...[Read More]

Four reasons for still observing cold spells despite the undeniable global climate change

Four reasons for still observing cold spells despite the undeniable global climate change

The winter of 2020-2021 has been characterized by various cold waves affecting – at different times – Western and Eastern Europe and North America.  The most striking pictures show Madrid covered by up to 40 cm of fresh snow, frozen Thames near London and Canal St Martin in Paris, heavy snow in Amsterdam and even on the Eolian Islands, just offshore Sicily. At first this seems contradi ...[Read More]
