The weekly round-up on the climate crisis and data on carbon dioxide levels in the atmosphere. 2022 was the year that saw the climate, energy and food crises combine.Energy markets have been on a roller coaster.In response to Russia's invasion of Ukraine, Western countries imposed financial sanctions on Russia and embargoed its oil exports.Russia has cut gas supplies to Europe and large importers, such as Germany, have had to reduce energy consumption and look elsewhere for supplies.Low- and middle-income countries have struggled to access affordable energy.Countries such as Pakistan, Bangladesh and Sri Lanka faced blackouts;rising fuel prices have spilled over into food markets.In 2023 (and in the years to follow), the energy crisis will change economic and energy balances and supply chains, and could have effects on the ecological transition. In an article on Nature, scholars Andrea Goldthau and Simone Tagliapietra have highlighted five issues that we will not be able to av...

More or less a year ago, on 15 June 2022, the lifeless bodies of the journalist from Guardian, Dom Phillips, and Bruno Pereira, the Brazilian expert from the body for the protection of indigenous peoples.They had disappeared about ten days earlier in the Yavarí valley, in the Amazon forest, during a trip to investigate the exploitation of the forest and the growing threats to which indigenous populations are subjected. Brazil, journalist Dom Phillips and activist Bruno Pereira killed while investigating illegal exploitation of the Amazon A year later, their killings appear to be increasingly linked to the interests of groups dedicated to illegal activities that the two were investigating.The Yavarí valley – one of the most isolated places on the planet, a reserve of 85 thousand square kilometers covered by the Amazon forest, without roads, where you can move by navigating the river and within which approximately 23 indigenous groups live who have no externa...

The weekly round-up on the climate crisis and data on carbon dioxide levels in the atmosphere. After more than half a century of research into nuclear fusion, a major breakthrough comes from the United States that could pave the way for enormous amounts of clean energy in the future.Researchers at the US National Ignition Facility, in California, said their fusion experiments released more energy than was pumped out by the lab's huge, high-powered lasers.This is a historic achievement, known as ignition or energy gain.Until now, in fact, experiments conducted around the world had required more energy than they had generated.However, writes the Guardian, this does not mean that we are in an energy utopia.This technology is still far from being ready to be transformed into power plants, it will not have any immediate effects on the climate crisis, but, as mentioned, it is a big step for science and research which demonstrates that fusion is a viable path to meet the planet's gr...

Underwater.This is how Faenza, Cesena, Forlì, some areas of the Ravenna area, some streets of Bologna ended, after the violent rains that hit Emilia Romagna and also the Marche since May 16th and which they provoked the death of 13 people, dozens missing, over 20 thousand displaced.41 municipalities were affected by the flood, 24 were flooded, 22 rivers flooded.Civil Protection he issued a new red alert for many territories of the two Regions until May 19th, both for the risk of landslides, collapses or mudslides, and for possible further flooding. “In terms of impacts on the territory, it is probably the most serious flood effect of at least the last 100 years.In terms of extension of the areas affected and quantity of precipitation, as well as damage to multiple provinces, it is something devastating, very serious", underlines Pierluigi Randi, president of AMPRO (Professional Weather Association).“A disaster announced, but we ignored the signs,” he comme...

The weekly round-up on the climate crisis and data on carbon dioxide levels in the atmosphere. Nord Stream, according to the Swedish prosecutor's office, a group linked to a state was behind the sabotage of the gas pipeline Update April 7, 2023: The Swedish prosecutor who is investigating the sabotage of the Nord Stream gas pipeline he stated that the "main scenario" prefigures that a "state actor" may be behind the attack, thus casting doubt on recent theories that hypothesized the responsibility of an independent group. The type of explosive used in the attacks excludes a "large part of possible perpetrators", prosecutor Mats Ljungqvist told the Reuters. According to a United Nations report, the three underwater explosions that severed the gas connection between Russia and Germany northeast and southeast of the Baltic Sea island of Bornholm on September 26, 2022 were equivalent to the power of several hundreds of kilograms of explosives.Swedish...
