Four leading Italian scientists have undertaken a major review of historical climate trends and concluded that a ‘climate emergency’ is not supported by the data. Reviewing data from a wide range of weather phenomena, they say the climate crisis that many say we are currently experiencing “is not evident yet”. The scientists suggest that rather than burdening our children with the anxiety of a climate emergency, we should allow them to face various problems such as energy, food and health with a more “objective and constructive spirit” and not waste limited resources on “costly and ineffective solutions”.
During the course of their recent work, the scientists found that rainfall intensity and frequency was stationary in many parts of the world. Tropical hurricanes and cyclones showed little change over the long term, and the same is true of U.S. tornadoes. Other meteorological categories including natural disasters, floods, droughts and ecosystem productivity showed no “clear positive trend of extreme events”. Regarding ecosystems, the scientists noted a considerable “greening” of global plant biomass in recent decades caused by higher levels of carbon dioxide in the atmosphere. Satellite data show “greening” trends over most of the planet, increasing food yields and pushing back of deserts.
The four scientists are all highly qualified and include physics adjunct professor Gianluca Alimonti, agrometeorologist Luigi Mariani and physics professors Franco Prodi and Renato Angelo Ricci. The last two physicists are signatories to the rapidly growing “World Climate Declaration”. This petition states that there is no climate emergency and calls for climate science to be more scientific. It also calls for a freeing from the “naïve belief in immature climate models”. In future, it says, “climate research must give significantly more emphasis to empirical science”.
