The weekly round-up on the climate crisis and data on carbon dioxide levels in the atmosphere. “Hydrogen's big gamble:fluff or is it the Holy Grail of net zero emissions?”, was the headline of one article of Guardian last October who wondered whether we can really rely on green hydrogen to achieve climate goals. An article by Adrian Odenweller and Falko Ueckerdt of the Potsdam Institute for Climate Impact Research, authors of one study published on Nature Energy in September, he tried to answer this question by analyzing how quickly the world would need to produce green hydrogen – produced by splitting water with electricity generated from low-carbon sources – to help limit warming to 1.5°C. Hydrogen:a solution to climate change or another gift to the fossil fuel industry?   Hydrogen is set to become one of the building blocks for achieving global climate goals, but current production comes almost exclusively from high-carbon sources. It...

The weekly round-up on the climate crisis and data on carbon dioxide levels in the atmosphere. COP 27 ended just over a week ago leaving jarring sensations:if on the one hand we can celebrate a success in the thirty-year battle for climate finance, on the other we must point out yet another failure that takes us further away from the objective of the Paris Agreement to contain global warming to within 1.5°C.Giving up permanently on the 1.5°C climate target would be a nice gift to carbon advocates, he said the executive director of the International Energy Agency (IEA) in an interview with Guardian. We will see what the effects of the decisions (not) taken will be in the years to come. The talks highlighted the central role of nature actions in tackling the climate crisis.In a special the World Economic Forum analyzed the progress made after the COP in Egypt. 1) Call for structural reform of nature and climate finance In addition to loss and damage financing, much atte...

The weekly round-up on the climate crisis and data on carbon dioxide levels in the atmosphere. December 5th has entered into force the $60 per barrel cap on Russian oil transported by sea imposed by the G7 countries, the European Union (with the exception of Bulgaria, which was given a longer period to comply) and Australia.The measure allows Russian crude to be shipped to third countries using tankers, insurance companies and G7 and EU lenders, only if the cargo is purchased at or below the price cap.Given that major shipping and insurance companies are based in G7 countries, the imposed limit could make it difficult for Moscow to sell its oil at a higher price.The level of the cap will be reviewed by the EU and the G7 every two months.The first review is scheduled for mid-January and “will need to take into account the effectiveness of the measure, its implementation, international take-up and alignment, market developments and the potential impact on member countries...

“A disaster announced, but we ignored the signs.” Meteorologist Luca Mercalli doesn't mince words about the flood that hit Emilia-Romagna, causing 13 victims and leaving 20,000 people homeless:«Global warming must be stopped, we are all guilty.Nobody wants to make sacrifices except the kids who fight for the climate." 500 mm of rain in a few days, as much as falls in a year in Aosta.The rivers cannot absorb such a quantity of water, the soaked soil collapses, the entire system goes into crisis. Floods in Emilia Romagna:an announced disaster and because climate change is also involved In its annual report on global average temperatures, the World Meteorological Organization (WMO) said there is a good chance that in the next five years the Earth will experiment new temperature records and global warming will exceed 1.5°C above pre-industrial levels, a threshold beyond which there could be far-reaching repercussions for health, food safety, water management an...

The weekly round-up on the climate crisis and data on carbon dioxide levels in the atmosphere. The G20 in Indonesia could also have important repercussions on the climate agenda and give a small jolt to the United Nations Climate Conference underway in Egypt.On November 14, on the eve of the G20 in Indonesia, US President Joe Biden and Chinese President Xi Jinping met.It is the first direct contact after the congress in China and the mid-term elections in the United States.The two leaders have taken steps towards reopening the climate dialogue, meeting the demands of US special climate envoy John Kerry, who just three weeks ago he had urged the two countries to resume negotiations. “The world expects, I think, that China and the United States will play a key role in addressing global challenges, from climate change to food insecurity, and that they will be able to work together.The United States stands ready to do just that, to work with you, if that is your desire,&rdq...
