GLOBAL warming could be twice as bad as predicted with “unstoppable” sea level rises and a green Sahara Desert, according to research published last week. Scientists say the world is warming at a rate “much faster than anything encountered in Earth’s history”. The impact could see the largest desert in the world turn lush green as the rise in temperature causes the rain belt surrounding Earth to swell. According to the study - conducted by dozens of researchers from 17 countries and published by Geoscience - there could be a 20-foot rise in sea level, leading to mass flooding. Ice caps will also collapse and the edges of tropical forests will be ravaged by fires due to "significant changes in ecosystems", the experts claim. Co-author Katrin Meissner, of the University of New South Wales in Australia, warned: “ In terms of rate of change, we are in uncharted waters.” This could mean the landmark Paris Climate Agreement – which seeks … [Read more...] about Global warming could be TWICE as bad as predicted with ‘unstoppable’ sea level rises and a GREEN Sahara desert
Global warming predictions
Doyle Rice USA TODAY Published 5:32 p.m. UTC Jul 6, 2018 Collapsing polar ice caps, a green Sahara Desert, a 20-foot sea-level rise. That's the potential future of Earth, a new study suggests, noting that global warming could be twice as warm as current climate models predict. The rate of warming is also remarkable: “The changes we see today are much faster than anything encountered in Earth’s history. In terms of rate of change, we are in unchartered waters,” said study co-author Katrin Meissner of the University of New South Wales in Australia. This could mean the landmark Paris Climate Agreement – which seeks to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels – may not be enough to ward off catastrophe. “Even with just 2 degrees of warming – and potentially just 1.5 degrees – significant impacts on the Earth system are profound,” said study … [Read more...] about Global warming could be far worse than predicted, new study suggests
From the Middle East to Russia, and Ireland to the US, temperature records the world over have been toppled during a week of unprecedented heatwaves that some will take as evidence of global warming. Records have been set in Belfast and Castlederg in Northern Ireland, where the mercury hit 29.5C (85.1F) and 30.1C (86.2F) respectively on 28 and 29 June, and south of the border it reached 32C (89.6F) in Shannon on 28 June.The Met Office also recorded the hottest June ever for Wales, where temperatures reached 33C (91.4F) in the coastal town of Porthmadog as the month drew to a close.Meanwhile, there have been some unprecedented conditions some 5,000 miles away in Oman.Residents in the small fishing village of Quriyat, on the northeast coast, had to endure temperatures of 42.6C (108.7F) for 51 hours straight last week.The unprecedented spell made for the highest nighttime temperature ever recorded anywhere in the world.While no records have fallen in Iraq, it has been so hot in parts of … [Read more...] about Proof of global warming?

James E. Hansen wiped sweat from his brow. Outside it was a record-high 98 degrees on June 23, 1988, as the NASA scientist testified before the Senate Committee on Energy and Natural Resources during a prolonged heat wave, which he decided to cast as a climate event of cosmic significance. He expressed to the senators his “high degree of confidence” in “a cause-and-effect relationship between the greenhouse effect and observed warming.” With that testimony and an accompanying paper in the Journal of Geophysical Research,... … [Read more...] about Thirty Years On, How Well Do Global Warming Predictions Stand Up?
Doyle Rice USA TODAY Published 6:20 p.m. UTC Jun 13, 2018 Global warming has caused over 3 trillion tons of ice to melt from Antarctica in the past quarter-century and tripled ice loss there in the past decade, a new study finds. The total is equivalent to over 4 quintrillion gallons of water added to the world's oceans, making Antarctica's melting ice sheets one of the largest contributors to rising sea levels. That amount of water is enough to fill over a billion swimming pools and cover Texas to a depth of nearly 13 feet. “Even though Antarctica is far from most human civilization, its ice sheet is losing mass to the ocean, and is an increasing contribution to sea-level rise," said study co-author Helen Amanda Fricker, a glaciologist at Scripps Institution of Oceanography. This "will have large impacts on coastlines all around all the world.” “The future we choose could determine when we need to rebuild airports, cities and infrastructure … [Read more...] about Global warming has melted over 3 trillion tons of ice in Antarctica since 1992, and it’s only getting worse
