Four leading Italian scientists have undertaken a major review of historical climate trends and concluded that declaring a ‘climate emergency’ is not supported by the data. Reviewing data from a wide range of weather phenomena, they say a ‘climate crisis’ of the kind people are becoming alarmed about “is not evident yet”. The scientists suggest that rather than burdening our children with anxiety about climate change, we should encourage them to think about issues like energy, food and health, and the challenges in each area, with a more “objective and constructive spirit” and not waste limited resources on “costly and ineffective solutions”.
During the course of their work, the scientists found that rainfall intensity and frequency is stationary in many parts of the world. Tropical hurricanes and cyclones show 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 show no “clear positive trend of extreme events”. Regarding ecosystems, the scientists note 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 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 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 liberation from the “naïve belief in immature climate models”. In future, it says, “climate research must give significantly more emphasis to empirical science”.

In bubbling vents off the coast of Ischia, a volcanic island in the Gulf of Naples, lives a curious population of black sea urchins. For at least 30 years, they have lived in these low pH, carbon dioxide-rich environments — a proxy for climate change-induced acidic oceans.
Now, University of Sydney researchers have determined they can also tolerate unprecedentedly warm sea temperatures — another climate change by-product. This means that these urchins, already one of the most abundant animals in the Mediterranean Sea, will likely plunder further afield as oceans continue to warm and become more acidic.
The researchers have described their findings in Biology Letters, a publication of the Royal Society.
The Mediterranean Sea is warming 20 percent faster than the global average, with predicted warming of up to 5.8°C by 2100.
“Given their ability to withstand a large temperature range, these sea urchins are likely to continue spreading throughout the Mediterranean Sea, with serious consequences for coastal habitats,” said lead researcher, University of Sydney marine biologist Dr Shawna Foo.

HE LONGEST, DEEPEST UNDERWATER GAS NETWORK IN THE WORLD
Greece, Italy, and Cyprus have reached an agreement with Israel to lay a pipeline connecting the Jewish state’s gas reserves to the three countries, in a major project estimated at costing over $7 billion that will supply gas from the eastern Mediterranean to Europe, as the continent seeks to diversify its energy supply.
According to Hadashot TV, the European Union agreed to invest $100 million in a feasibility study for the project before the agreement was reached over the laying of the longest and deepest underwater gas pipeline in the world.

The timing and size of three deadly earthquakes that struck Italy in 2016 may have been pre-determined, according to new research that could improve future earthquake forecasts.
A joint British-Italian team of geologists and seismologists have shown that the clustering of the three quakes might have been caused by the arrangement of a cross-cutting network of underground faults.
The findings show that although all three earthquakes occurred on the same major fault, several smaller faults prevented a single massive earthquake from occurring instead and also acted as pathways for naturally occurring fluids that triggered later earthquakes.
