The “new abnormal” the world is facing from risks like nuclear war and climate change has led the symbolic Doomsday Clock to be frozen at the closest it has ever been to midnight. The clock, created by the Bulletin of the Atomic Scientists (BAS) in 1947, intends to warn of impending disasters. Its 2019 setting was announced on Thursday – staying in the same perilous position it was set at last year. The BAS has warned we are “normalizing a very dangerous world”.
Greenland’s ice is melting faster than scientists previously thought, with the pace of ice loss increasing fourfold since 2003, new research has found. This suggests surface ice is simply melting as global temperatures rise, causing gushing rivers of meltwater to flow into the ocean and push up sea levels. South-west Greenland, not previously thought of as a source of woe for coastal cities, is set to “become a major future contributor to sea level rise”, the research states.
An international team of scientists has developed a diet it says can improve health while ensuring sustainable food production to reduce further damage to the planet. The “planetary health diet” is based on cutting red meat and sugar consumption in half and upping intake of fruits, vegetables and nuts. The authors warn that a global change in diet and food production is needed as 3 billion people across the world are malnourished — which includes those who are under and overnourished — and food production is overstepping environmental targets, driving climate change, biodiversity loss and pollution.
A deal was made at the UN climate conference in Poland on Saturday to add fuel to the 2015 Paris Climate Accord and continue moving forward with plans to cut carbon emissions. With 25,000 delegates present the deal made clarified rules for nearly 200 countries to work on cutting greenhouse gas production.
The UN climate change summit begins on Monday amid warnings that the current generation is the last with the chance to prevent devastating global warming as well as the first that will experience its effects firsthand. The two-week summit includes nearly 200 nations. Senior figures opened the summit saying the planet ‘is at a crossroads.’
According to a report by 150 experts climate change is already damaging people’s health. The Lancet Countdown on Health and Climate Change says the health effects include dengue fever in tropics and deadly heatwaves in Europe. High temperatures damaged the ability to grow crops. The report highlights the lack of progress in preventing climate change.
A new study shows that there has been a serious underestimation about the amount of heat soaked up by oceans in the past 25 years. Researchers claim oceans soaked up 60% more heat than previously thought. This discovery shows that Earth is more sensitive to fossil fuel emissions than believed.
The UN Intergovernmental Panel on Climate Change (IPCC) released a shocking report on Monday warning that we have just 12 years to limit global warming to a maximum of 1.5C. Extending beyond the maximum will result in droughts, floods, extreme heat and poverty for millions. The authors of the report said urgent change is necessary.
President Trump will unveil a proposal this week in a major overhaul to the Obama administration’s signature climate policy. The proposal will allow states to establish emission standards for coal-fired power plants, causing at least 12-times more carbon dioxide to be released into the atmosphere. Trump aims to revive the US coal industry.
A study by an international team of researchers published in the journal Proceedings of the National Academy of Sciences claims the Earth is heading toward boiling hot temperatures and towering seas in the centuries to come. The study says a ‘hothouse Earth’ will threaten the ‘habitability of the planet for human beings.’
