0 Have your say So there’s good news and bad news when it comes to predicting how hot the planet will get as a result of climate change, according to new research. Scientists from the University of Exeter and the UK’s Centre of Ecology and Hydrology have developed a new method they claim can more accurately estimate the likely global temperature rise due to greenhouse gases in the atmosphere. Their findings have narrowed the previously accepted, fairly wide, range by 60 per cent. Experts at the Intergovernmental Panel on Climate Change has forecast warming of between 1.5C and 4.5C if the atmospheric concentration of carbon dioxide is stabilised at double pre-industrial levels. But the latest study suggests a smaller range of 2.2C to 3.4C, based on analysis of year-on-year temperature fluctuations instead of warming trends to date.So it could be better, but also could be worse – depending on what the world does next.Exeter’s Professor Peter Cox explains: … [Read more...] about Ilona Amos: There’s some good news – and bad – about global warming
In 2015, something strange happened as nearly 90% of saiga antelopes living in central Kazakhstan dropped dead in a matter of three weeks. The mysterious demise of some 200,000 antelopes, which is 62% of the global population of the critically endangered animal, took the world by storm at that time. Now, a group of UK-based researchers has got some insights into what may have triggered the mass tragedy. When saiga antelopes started dying at an alarming rate, scientists from different parts of the world came together to study the dead animals and conduct autopsies. Soon, they figured out that all of them suffered from internal bleeding or blood poisoning, a condition called Hemorrhagic septicaemia caused by a bacterium called Pasteurella multocida. As the bacterium, found in the tonsils of saigas, is typically harmless, researchers had no clue how it became deadly enough to harm the animals. The mystery stood for three long years until an international team of researchers posited a … [Read more...] about Did global warming kill 200,000 critically endangered saiga antelope in just three weeks?
Findings should not been seen as taking pressure off the need to tackle climate change, researchers warn 0SHARES Share Tweet Email PHOTO: AFP PARIS: Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions. A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature. “Our study all but rules out very low and very high climate sensitivities,” said lead author Peter Cox, a professor at the University of Exeter. How effectively the world slashes CO2 and methane emissions, improves energy efficiency, and develops technologies to remove CO2 from the air will determine whether climate change remains manageable or unleashes a maelstrom of … [Read more...] about Study reveals worst-case global warming scenarios not credible
140 scientists from all over the world are participating in global conference on climate change 0SHARES Share Tweet Email PHOTO: FILE ISLAMABAD: Prime Minister Shahid Khaqan Abbasi has said that the government has set aside more than 8% of budget for climate-related actions. The PM was speaking at the inaugural session of the Science-Policy Conference on Climate Change organised on Monday by the Ministry of Climate Change’s research wing, the Global Change Impact Studies Centre (GCISC). Pakistan needs access to global funds to cope with climate change Other institutions that collaborated in the endeavour included the US-Pakistan Centre for Advanced Studies in Water (USPCAS-W), the Mehran University of Engineering and Technology (MUET), the University of Utah, the Sustainable Development Policy Institute (SDPI), the Commission on Science and Technology for Sustainable Development in the South (COMSATS), the Higher Education … [Read more...] about Global warming: 8pc allotted for climate actions, says PM
This future of the human race could depend on this humble looking bunker in the middle of the Arctic Circle. The 'doomsday' building contains the one vital resource humanity cannot live without. But it isn't filled with oil, or fuel, or money. Instead the bunker contains hundreds of thousands of varieties of seeds. Run by the Global Seed Vault and based on part of the Svalbard archipelago in Norway, the building contains 130,000 years of agricultural history. Inside its walls there are seeds for more than 930,000 varieties of food crops, which could prove vital to humanity should wars or global warming wipe out the food we grow. The doomsday seed vault is built 150 metres deep into the mountainside. A huge steel door marks the opening of the remote vault and there is a tunnel to enable trolleys to carry seeds into the vault. The building is made up of three vault rooms, but only the middle chamber contains the seeds. As well as modern varities of seeds, the vault contains wild and … [Read more...] about Arctic doomsday bunker holds the keys to human survival against wars and global warming
