Climate change: Sea ice loss linked to spread of deadly virus

Climate change: Sea ice loss linked to spread of deadly virus

Science
The decline in sea ice seen in the Arctic in recent decades has been linked by scientists to the spread of a deadly virus in marine mammals. Researchers found that Phocine distemper virus (PDV) had spread from animals in the North Atlantic to populations in the North Pacific.The scientists say the spread of pathogens could become more common as ice declines further.The 15-year study tracked seals, sea lions and otters via satellite. The loss of sea ice in the Arctic has been one of the most visible signs of climate change on the planet over the past four decades. According to the Intergovernmental Panel on Climate Change, the ice has been retreating by around 12% per decade between 1979 and 2018."These sea ice changes in Septembe...
Carbon capture could be climate change solution, or a waste of time

Carbon capture could be climate change solution, or a waste of time

Science
Nov. 8 (UPI) -- Earlier this year, the U.S. Department of Energy's Office of Fossil Energy announced $ 110 million in federal funding for research and development of carbon capture and storage projects. According to DOE, carbon capture and storage technologies, or CCS, are "increasingly becoming widely accepted as a viable option" for coal- or gas-fired power plants to reduce their emissions. Carbon capture technologies promise to scrub CO2 from the flumes and exhaust pipes of coal and gas plants. The captured carbon can be permanently buried underground or sold for other uses like making fertilizers or boosting oil extraction. The technologies have been tested on small scales, but high costs have prevented wide-scale adoption. While subsidy-free wind and solar power now offer the cheape...
Climate change: ‘Clear and unequivocal’ emergency, say scientists

Climate change: ‘Clear and unequivocal’ emergency, say scientists

Science
A global group of around 11,000 scientists have endorsed research that says the world is facing a climate emergency.The study, based on 40 years of data on a range of measures, says governments are failing to address the crisis.Without deep and lasting changes, the world is facing "untold human suffering" the study says.The researchers say they have a moral obligation to warn of the scale of the threat. Released on the day that satellite data shows that last month was the warmest October on record, the new study says that that simply measuring global surface temperatures is an inadequate way of capturing the real dangers of an overheating world. So the authors include a range of data which they believe represents a "suite of graphical vital signs of clima...
Climate change: Thousands invited to join citizens’ assembly

Climate change: Thousands invited to join citizens’ assembly

Science
Letters are being sent to 30,000 households across the UK inviting people to join a citizens' assembly on climate change.Once participants are selected, the assembly will meet next year, with the outcome of their discussions reported back to Parliament.The initiative, set up by cross party MPs, will look at what members of the public can do to reduce CO2. The UK government has committed to cut carbon emissions to net zero by 2050.Rachel Reeves, chair of the Business, Energy and Industrial Strategy (BEIS) Committee, one of six select committees who commissioned the climate assembly, said a clear roadmap was needed to achieve this goal."Finding solutions which are equitable and have public support will be crucial," she said. "Parli...

Climate change: Spain offers to host COP25 in Madrid

Science
Just a day after the President of Chile said his country could no longer hold the world's annual climate conference, Spain has offered to host it in Madrid.The critical meeting, called COP25, was due to take place in Santiago for two weeks from 3 December.Chilean President Sebastián Piñera said his government needed "to prioritise re-establishing public order" after serious anti-government protests.Spain's offer will be considered by the UN's climate body next week.The Spanish government said it considered multilateral action on climate change to be a priority for the UN.The annual Conference of the Parties (COP) is usually an important moment for taking stock of where the world stands on climate change. For a quarter of a century, negotiators from almost
