25 September 2019 Cyclones, hurricanes and more powerful typhoons; rising seas faster; coastal megalopolises that will suffer climatic catastrophes every year. The picture that emerges from the UN experts' report on the climate is disheartening. A cry of alarm that cannot leave the governments of the world indifferent.

More powerful cyclones, hurricanes and typhoons
Cyclones, hurricanes and typhoons will become more powerful even in a +2 C world, causing greater damage to the coasts. This is what emerges from the report of the UN experts on climate. "The average intensity" of tropical cyclones and the percentage of category 4 and 5 cyclones, which has already increased in recent decades, "should increase", although cyclones in general should not be more frequent.

Sea level rise 2.5 times faster than in the 20th century
Sea levels rose 2.5 times faster at the beginning of the 21st century than in the 20th, and will continue to increase mainly due to the reduction in ice caps, the report says. Whatever the scenarios, the sea will continue to rise after 2100. In a world of +2 C the growth rate could stabilize, reaching around 1 meter in 2300, compared to several meters if greenhouse gas emissions continue at the same rate as today, according to this document.

By 2050 coastal megalopolis will suffer climatic catastrophes every year
By 2050, therefore, many coastal megalopolises and small island nations will suffer climatic catastrophes every year, even with an aggressive reduction in greenhouse gas emissions. More than a billion people, by mid-century, will live in areas prone to cyclones, large-scale floods and other extreme weather events amplified by rising seas, as predicted by the Intergovernmental Committee on Climate Change.

"How much does it cost to protect the coasts?"
Building protection against rising water levels could reduce the risk of flooding from 100 to 1,000 times if it invested "from tens to hundreds of billions of dollars a year", according to the report. What works for coastal megalopolis, however, is less effective for agricultural deltas or small atolls, scientists warn, knowing that island states will not have the means to spend the equivalent of "different" points of GDP.

Global Strike For Climate: Friday thousands of Italian students in the square
Parades, demonstrations, sit-ins and flash-mobs with thousands of students in the streets in dozens of Italian cities and a general strike of all categories that threatens to create many inconveniences in public services, from schools, to health, to transport. It is the "Global Strike For Climate", the third global climate strike, called for 27 September by the environmental movement Fridays For Future (FFF), led by the young Swedish activist Greta Thunberg: after a week of mobilizations in coinciding with the UN climate summit in New York, mobilization will also culminate in Italy this Friday.

"It will be a historic event, an event for students and professors, an event for families, a peaceful and non-violent event. We will all be united for the climate", say the activists of FFF Italia. Supported by a massive Internet tam-tam, with numerous groups on the main social networks, the Italian mobilization to ask governments to change environmental policies, and avoid a point of no return on climate change, sees appointments already planned in over 150 cities, from Bolzano to Ragusa.

The largest demonstration will take place in Rome, with a procession of students starting from Piazza della Repubblica at 9.30am to reach Piazza della Madonna di Loreto, where a sit-in will be held until 2.30pm. But events including marches, demonstrations, sit-ins and flash-mobs are also planned in Milan (from 9.30 am from Largo Cairoli), Naples (from 9 am in Piazza Garibaldi), Turin (from 9.30 am in Piazza Statuto), Palermo (from 9 am in Piazza Verdi), Florence (from 9 in Piazza di Santa Maria Novella), Bologna (from 9.30 in Piazza San Francesco) and in dozens and dozens of other cities.

The participation of thousands of students is expected, also supported by the Minister of Education Lorenzo Fioramonti who with a circular said he hoped that the schools, in their autonomy, could justify the absence from classes, motivated by participation in the events, "given the civic value that participation has ".

"Until recently, having to study was a matter of course, needed to find a job, but if our governments, corporations, and our lifestyles were to continue to remain so and to act in unsustainable ways, the work we will dream of it ", say the activists of FFF:" What we will see will be war, drought, floods, famine, migration, death ... We are destined to live a scenario identical to that of a post-apocalyptic film ". The trade unions have also mobilized for the Global Strike For Climate.

Greenpeace Italy: "Report confirms serious impacts also on the oceans"
The special report of the IPCC (Intergovernmental Group on Climate Change) on oceans and ice-covered areas puts on paper the crisis of our oceans, seriously affected by climate change. "Science offers us a framework that is both chilling and convincing. The impacts that man-made carbon emissions have on our oceans are developing on a large scale and at a much faster pace than we expected: there is a need therefore of unprecedented political action to prevent our planet from suffering devastating human, environmental and economic consequences, "said Giorgia Monti, Greenpeace Italia campaign manager.
