Casi 60 países respaldan hojas de ruta voluntarias para desvincular al mundo del carbón, el petróleo y el gas. Se ha pedido a los gobiernos que desarrollen “hojas de ruta” nacionales que establezcan cómo pondrán fin a la producción y el uso de combustibles fósiles, tras una reunión climática histórica en la que participaron casi 60 países. Los planes voluntarios formarán la base de una nueva iniciativa para alejar al mundo del carbón, el petróleo y el gas, el foco de dos días de intensas conversaciones en Colombia esta semana.

Research finds global heating has already lengthened the pollen season in addition to worsening heatwaves and droughtsClimate breakdown has extended the pollen season in the UK and mainland Europe by between one and two weeks since the 1990s, a study has found, adding itchy eyes and runny noses to the harm wrought by fossil fuel pollution.The finding may be less dramatic than the floods and wildfires typically associated with a warming planet but represents a “huge” increase in the combined suffering of tens of millions of people, the researchers say.

Social workers in England say they often have no choice but to place children in unregistered settings because no one else will take themThe sinking feeling is familiar now, says Anna*. It’s Friday, the clock is ticking, and there is a vulnerable child in her care for whom – despite hitting the phones for days – she cannot find a place. Once the foster carers have been exhausted, and the registered private children’s homes begged, there is nothing for it but to look elsewhere.“It always seems to be on a Friday that you are struggling to place a child,” says the social worker. “They need somewhere safe tonight. You’re calling everywhere, already knowing the answer will be, ‘we haven’t got any spaces’. And then you’re left with what’s left of a hotel, a caravan … somewhere you know isn’t right, but you don’t have a choice.” Continue reading...

Prime minister elect says he expects new government to be in place by mid-MayElection winner Péter Magyar has confirmed work is under way to form the new Hungarian government by mid-May after holding talks with the country’s president, Tamás Sulyok, a loyalist of the outgoing prime minister, Viktor Orbán.The two leaders discussed the timetable for new parliament, which can be formed not before 4 May when the results of the Sunday’s vote need to be certified by, with Magyar saying he expected the new government to be in place by mid-May.“[Sulyok] is unworthy of representing the unity of the Hungarian nation. He is unfit to serve as the guardian of legality. He is not fit to serve as a moral authority or a role model.” Continue reading...

Rising temperatures and extreme drought are driving more destructive spring fires across the American Great Plains. This year, forces aligned to create the perfect storm in NebraskaIn a normal year, the vast grasslands that roll across the American Great Plains would be starting to green. But at the center of the US, where most of the nation’s beef producers graze their herds, this spring brought fire instead of moisture, leaving more than a million acres black and barren.Multiple blazes raged across Nebraska, where the records for the annual acreage burned were obliterated in a single month. The state logged the largest blaze ever recorded when the Morrill fire cascaded across more than 642,000 acres before it was contained in March. Continue reading...

Use of glyphosate has risen 10-fold in 30 years, raising fears for public healthIt was Scottish farmers in the 1980s who pioneered the practice of spraying glyphosate on their wheat just before harvest. Struggling in the damp glens to get their crop to dry evenly, they came up with the idea of accelerating the process by killing it a week or two before harvesting.Glyphosate, then a revolutionary herbicide that killed everything plant-based but spared animal life, seemed perfect for the job. Soon the practice spread to wetter, colder agricultural regions around the world. Continue reading...
